Background technique

With the continuous improvement of the level of technology and people's living standards, more and more people have begun to buy cars to enhance the convenience and quality of life. However, due to the continuous increase of the current car capacity, the emission of car exhaust has brought a greater impact on the ecological environment. In order to improve the deteriorating ecological environment, electric vehicles were born. Electric vehicles use electricity to provide energy to drive vehicles. They will not produce vehicle exhaust during driving, which has a greater effect on reducing vehicle exhaust and improving environmental pollution. However, limited by the bottleneck of the development of electric vehicle battery technology, the current range of electric vehicles is generally low, which cannot meet people's long-term and long-distance use.

Please refer to FIG. 1, which shows a structural block diagram of a charging control system according to a preferred embodiment of the present invention.

In this embodiment, in the community, in order to facilitate charging by residents, a charging device is provided near the community parking space so that the user can use the charging device for charging after parking the vehicle in the parking space. Further, the charging devices are all connected to the charging control system 100 to receive a control command from the charging control system 100 to perform charging control.

Further, the charging control system 100 includes a power acquisition unit 10, a comparison unit 20, a processing unit 30 and a control unit 40. The power acquisition unit 10 is used to acquire the real-time power load of the community and transmit the real-time power load to the comparison unit 20. The real-time power load includes the electric current of the residents and the charging current of the charging device, specifically, In this embodiment, the real-time power load is the sum of the residential electricity current and the charging current of the charging device; the comparison unit 20 is electrically connected to the power acquisition unit 10 for comparing the real-time The electric load and the pre-stored safe current threshold value and get the comparison result. The processing unit 30 is electrically connected to the comparison unit 20, and is configured to receive the comparison result of the comparison unit 20 and calculate the total regulated current and at least one adjustable current of the charging device according to the comparison result, and according to The total regulated current and the at least one adjustable current screen the charging device to be regulated and obtain the current regulating target value of the charging device to be regulated. The current regulating target value includes a first preset value and a second preset value. At least one of the preset value, the third preset value, and 0.

Further, in this embodiment, the total regulated current is the total current that needs to be reduced by the charging equipment connected in the grid when the real-time electric load is not less than the safe current threshold, or the real-time electric load When it is less than the safe current threshold, the total current that needs to be increased by the charging equipment connected in the power grid.

Further, in order to maintain the stability of the community power load, it is necessary to reduce or increase the charging current of the charging device according to the real-time power load condition of the community power grid. Therefore, the total regulated current calculated by the processing unit 30 includes the total reduced current or the total increased current. Current. The total reduced current is the sum of the charging currents required to be reduced by all charging devices in the power grid when the real-time electrical load is greater than the safe current threshold; the total reduced current is the sum of the real-time electrical load less than When the safe current threshold is set, the sum of the charging currents that all charging devices in the power grid need to increase. For example: when the real-time power load is 20A higher than the safe current threshold, the total regulated current is the total reduced current, and the total reduced current is 20A; the real-time power load is lower than the safe current At 10A, the total regulated current is the total ramp-up current, and the total ramp-up current is 10A.

Further, in order to determine how to perform charging regulation, the processing unit 30 also needs to further calculate the adjustable current of the charging device, and the adjustable current is that all the charging devices in the power grid reduce the charging current to the The sum of at least one of the second preset value, the third preset value, and 0, the charging current that needs to be reduced, or the charging current is increased to the third preset value and the second preset value At least one of and the first preset value is the sum of charging currents that need to be increased. It can be understood that, because the charging current of the charging device needs to be adjusted down or up according to the real-time power load, the adjustable current includes an adjustable down current and an adjustable up current, and the adjustable down current is the same as the total adjusted current. The corresponding setting of the reduced current is used as a basis for reducing the charging current of the charging device, and the adjustable reduced current is that all the charging devices in the power grid reduce the charging current to the second preset value, the first The sum of the charging current that needs to be reduced by any one of the three preset values and 0; the adjustable up current is that all the charging devices in the power grid increase the charging current to the third preset value, the The sum of the charging current that needs to be increased by any one of the second preset value and the first preset value. Further, the adjustable boost current and the total boost current are set correspondingly to serve as a basis for boosting the charging current of the charging device. For example, the current power grid includes one charging device A, and the charging current of the charging device A is 31A. In this embodiment, there are three current levels, namely 32A, 16A, and 10A. Then the adjustable boost current is 1A, the adjustable drop current is 15A, 21A or 31A.

Further, in order to ensure the safety of charging regulation, when reducing the charging current, it is necessary to ensure that the adjustable reduction current is not less than the total reduction current, that is, the sum of the reduced charging currents of all charging devices is not less than the total reduction current. To reduce the current, when increasing the charging current, it is necessary to ensure that the adjustable up current is not greater than the total boosted current, that is, the sum of the up-regulated charging currents of all charging devices is not greater than the total boosted current, so as to ensure charging after regulation The current of the device does not exceed the safe current threshold.

The regulating unit 40 is electrically connected to the processing unit 30, and is configured to receive the charging device to be regulated and the current regulating target value, and regulate the charging current of the charging device to be regulated to the first At least one of a preset value, the second preset value, the third preset value, and 0. Further, in this embodiment, since the charging current of the charging device can be controlled to any one of the first preset value, the second preset value, the third preset value, and 0, Therefore, the current control target value includes at least one of the first preset value, the second preset value, the third preset value, and zero.

Further, the power obtaining unit 10 is set on the community power line, and can obtain the power consumption current of the residential power line in the community and the charging current of the charging equipment to obtain the real-time power load of the community. The electric current of the residential power line and the charging current of the charging device are in a changing state with the residential electric and vehicle charging. Therefore, the real-time power load obtained by the electric power acquisition unit 10 is also in a changing state, and it is possible As the residents' electricity current or the charging current of the charging equipment increases and exceeds the upper limit of the circuit line of the community, accidents such as tripping may occur. For example, if the residential electricity current acquired by the power acquisition unit 10 is 1000A, and the charging current of the charging device is 500A, then the real-time power load is 1000A+500=1500A.

Further, the power acquisition unit 10 obtains the real-time power load and transmits it to the comparison unit 20, and the comparison unit 20 compares the real-time power load with a pre-stored safe current threshold to obtain a comparison result . It can be understood that because the community power line has a rated current, in order to prevent the community power current from exceeding the rated current setting a safety factor, the safe current threshold is obtained based on the rated current and the safety factor, and When the real-time electric load exceeds the safe current threshold, charging control will be performed to prevent the real-time electric load of the community from reaching or exceeding the rated current, which may cause a trip or power failure. Further, in this embodiment, the safe current threshold is the product of the rated current of the community power grid and a safety factor. For example, if the rated current of the community power grid is 2000A, and the safety factor is 0.9, the safe current threshold is 2000A*0.9=1800A.

Further, since the safe current threshold is less than the rated current, if the real-time power load of the community is less than the safe current threshold, it means that the current total load of the community is low, and the charging current of the charging device can be increased at this time. Improve charging efficiency; if the real-time power load of the community is greater than the safe current threshold, it means that the total load of the current community is relatively high, and charging regulation needs to be carried out in time to reduce the charging current of the charging device so as not to exceed the safe Under the premise of current threshold, priority is given to ensuring residential electricity consumption. Therefore, it is necessary to compare the real-time power load and the safe current threshold to determine how to perform charging regulation to maintain the normal operation of the community power grid.

Further, when the comparison result received by the processing unit 30 is that the real-time electrical load is not less than the safe current threshold, it indicates that the current community load is relatively high, and the charging current of the charging device needs to be reduced. The processing unit 30 needs to calculate the total reduced current, and also needs to calculate the adjustable reduced current of the charging device in order to determine how to perform charging adjustment, so as to facilitate the calculation of the total reduced current and the adjustable reduced current The charging equipment to be regulated is screened and the current regulation target value of the charging device to be regulated is obtained.

Further, when the comparison result received by the processing unit 30 is that the real-time power load is less than the safe current threshold, it indicates that the current community load is low, and the charging current of the charging device needs to be increased. The processing unit 30 needs to calculate the total boost current, and also needs to calculate the adjustable boost current of the charging device in order to determine how to perform charging regulation, so as to screen based on the total boost current and the adjustable boost current The charging device to be regulated and obtain the current regulating target value of the charging device to be regulated.

Further, in this embodiment, the processing unit 30 is specifically configured to divide the charging device into at least one charging set according to the charging current of the charging device, and according to the total regulation current and the adjustable current The charging device is selected as the charging device to be regulated from the charging set. It can be understood that the charging device to be regulated is a charging device that needs to increase or decrease the charging current. Further, in this embodiment, the charging set includes a first charging set, a second charging set, and a third charging set, and the processing unit 30 further determines that the charging current is not greater than a first preset value and greater than all The charging equipment of the second preset value is classified into the first charging set, and the charging current is not greater than the second preset value and greater than the third preset value. The charging equipment is classified into the second Charging set, and dividing the charging current not greater than the third preset value into the third charging set. In this embodiment, the first preset value is 32A, the second preset value is 16A, and the third preset value is 10. It can be understood that dividing the charging device into different charging sets based on the difference in charging current facilitates the rapid calculation of the level of the adjustable current and the comparison of the adjustable current with the total regulated current so as to quickly filter out the proposed model. And calculate the current regulation target value of the charging device to be regulated. For example: the power grid includes a charging device a, a charging device b, and a charging device c. The charging current of the charging device a is 30A, the charging current of the charging device b is 28a, and the charging current of the charging device c is 25A, since the three current values of 30A, 28A, and 25A are all greater than 16A and less than 32A, the charging device a, the charging device b, and the charging device c are all divided into the first charging set; in the power grid Including charging device d, charging device e, and charging device f. The charging current of the charging device d is 22A, the charging current of the charging device e is 20A, and the charging current of the charging device c is 15A. The two current values are greater than 16A and less than 32A, so the charging device d and the charging device e are classified into the first charging set. Since 15A is greater than 10A and less than 16A, the charging device f is classified into the second charging set The power grid includes charging equipment A, charging equipment B, charging equipment C, charging equipment D, charging equipment E, the charging current of the charging equipment A is 20A, the charging current of the charging equipment B is 25A, the If the charging current of the charging device C is 15A, the charging current of the charging device D is 9A, and the charging current of the charging device E is 8A, the processing unit 30 divides the charging device A and the charging device B into In the first charging set, the charging device C is classified into the second charging set, and the charging device D and the charging device E are classified into the third charging set. In summary, since the current value of the charging equipment in the power grid is between 0-32A, when dividing the charging set, the charging equipment in the power grid can be divided into at least one charging set.

Further, in this embodiment, when the charging device is performing current reduction, the current control target value is the first preset value, the second preset value, the third preset value or 0, so the calculation is adjustable. When the current is reduced, the adjustable reduced current can be obtained according to the difference between the current current and the first preset value, the second preset value, the third preset value or 0. Further, in this embodiment, the charging devices of the first charging set, the second charging set, and the third charging set adjust the charging current according to the first charging set, the second charging set, The order of the third charging set sequentially reduces the charging current. For example, when reducing the charging current, the charging current of the charging device of the first charging set is first adjusted to the first preset value, and then the charging current of the charging device of the second charging set is adjusted to the desired value. According to the second preset value, the charging current of the charging device of the third charging set is adjusted to 0, and the charging current of the charging device of the first charging set is adjusted to the second preset value , And finally adjust the charging current of the charging device of the first charging set to zero.

Further, further, in this embodiment, when the charging device performs current increase, the current increase target value is the first preset value, the second preset value, and the third preset value. Therefore, when calculating When the current is adjustable, the adjustable current can be obtained according to the first preset value, the second preset value, the third preset value and the current current. Further, in this embodiment, the charging devices of the first charging set, the second charging set, and the third charging set increase the charging current according to the third charging set, the second charging set, The order of the first charging set increases the charging current in turn. For example: when the charging current is increased, the charging current of the charging device of the third charging set is first increased to the third preset value, and then the charging current of the charging device of the second charging set is increased to In the second preset value, the charging current of the charging device of the first charging set is increased to the first preset value, and then the charging current of the charging device of the third charging set is increased to The second preset value finally increases the charging current of the charging device of the third charging set to the first preset value.

Further, the charging current of the charging equipment in the first charging set can be adjusted to the second preset value, the third preset value or 0, and the charging current of the charging equipment in the second charging set is adjustable If it is lowered to the second preset value or 0, the charging current of the charging device in the third charging set can be adjusted to 0. Therefore, in this embodiment, the adjustable drop current includes the first adjustable drop. Current, the second adjustable drop current, the third adjustable drop current, the fourth adjustable drop current, the fifth adjustable drop current, and the sixth adjustable drop current, the first adjustable drop current is the first The sum of the quasi-reduced current, the first quasi-reduced current is the difference between the charging current of the charging device in the first charging set and the second preset value, and the second adjustable current is The sum of the second quasi-reduced current, the second quasi-reduced current is the difference between the charging current of the charging device in the second charging set and the third preset value, and the third can The reduced current is the sum of the third quasi-reduced current, the third quasi-reduced current is equal to the charging current of the charging device in the third set, and the fourth adjustable current is the fourth The sum of the quasi-reduced current, the fourth quasi-reduced current is the difference between the charging current of the charging device in the first charging set and the third preset value, and the fifth adjustable current is The sum of the fifth quasi-reduction current, the fifth quasi-reduction current is equal to the charging current of the charging device in the second charging set, and the sixth quasi-reduction current is the sixth quasi-reduction The sum of the currents, the sixth standard reduced current is equal to the charging current of the charging device in the first charging set.

Further, the charging current of the charging devices in the first charging set can be adjusted to the first preset value, and the charging current of the charging devices in the second charging set can be adjusted to the second preset value. Setting value or the first preset value, the charging current of the charging device in the third charging set can be adjusted to the third preset value, the second preset value, or the first preset Therefore, the adjustable rise current includes the first adjustable rise current, the second adjustable rise current, the third adjustable rise current, the fourth adjustable rise current, the fifth adjustable rise current, and the sixth adjustable rise current. The first quasi-boost current is the sum of the first quasi-boost current, and the first quasi-boost current is the third preset value and the charging current of the charging device in the third charging set The second quasi-boost current is the sum of the second quasi-boost current, and the second quasi-boost current is the difference between the second preset value and the charging equipment in the second charging set The difference between the charging current, the third adjustable boost current is the sum of the third quasi-boost current, and the third quasi-boost current is the first preset value and the charging in the first charging set The difference between the charging current of the device, the fourth quasi-boosting current is the sum of the fourth quasi-boosting current, and the fourth quasi-boosting current is the second preset value and the third charging set The difference between the charging current of the charging device, the fifth adjustable up current is the sum of the fifth quasi up current, and the fifth quasi up current is the first preset value and the second charging The difference between the charging currents of the charging devices in the set, the sixth adjustable rising current is the sum of the sixth quasi-raising current, and the sixth quasi-raising current is the first preset value and the first The difference between the charging currents of the charging devices in the three charging sets.

Further, after calculating the total reduced current and the adjustable reduced current, it is necessary to further select the total reduced current and the adjustable reduced current from the first charging set and the second charging set. The charging device to be regulated is selected from the collection and the third charging collection and the current regulating target value of the charging device to be regulated is determined.

Further, the processing unit 30 is configured to select some charging devices from the first charging set as the charging devices to be regulated when the first adjustable drop current is not less than the total drop current, And it is obtained that the current regulation target value of the charging device to be regulated in the first charging set is the second preset value. It can be understood that if the first adjustable drop current is not less than the total regulation current, it means that the regulation requirement can be met by reducing the part of the charging equipment in the first charging set to the second preset value. Therefore, according to the sequence of the charging access time, some charging devices from the first charging set may be selected as the charging devices to be regulated. Further, the processing unit 30 is specifically configured to form the charging devices in the first charging set into a first down-regulating sequence according to the sequence of charging access time, and to select a part of the charging devices from the first down-regulating sequence. The device serves as the charging device to be regulated. Further, the processing unit 30 is specifically configured to sequentially accumulate the first quasi-down-regulated currents of the charging devices in the first down-regulation sequence and compare with the total down-regulated current, and compare the results in the first step-down sequence. When the sum of a quasi-reduction current is not less than the total reduction current, the accumulated charging device corresponding to the first quasi-reduction current is selected as the charging device to be regulated. For example: the total reduced current is 20A, the charging devices in the first charging set are charging device A, charging device B, and charging device C. The charging access time of charging device A is 8:01, and the charging current Is 24A, the charging connection time of charging device B is 8:30, the charging current is 31A, the charging connection time of charging device C is 9 o’clock, and the charging current is 27A, then the first downgrade sequence is the charging device A. Charging device B and charging device C, the first adjustable drop current is 8A+15A+11A=34A, the first adjustable drop current is greater than the total drop current, and the processing unit 30 The first quasi-dropping current of the charging device A and the charging device B accumulates to 8A+15A=23A, which is greater than the total reduced current of 20A, and the processing unit 30 selects from the first drop-down sequence The charging devices corresponding to 8A and 15A, namely charging device A and charging device B, are used as the charging devices to be regulated; if the total reduced current is 33A, the processing unit 30 will charge device A and charging device B The accumulated first reduced current of the charging device C is 8A+15A=23A, which is less than the total reduced current of 33A, so continue to accumulate the first reduced current of the charging device C to 8A+15A+11A=34A, which is greater than If the total reduced current is 33A, the processing unit 30 selects from the first reduced sequence the charging devices corresponding to the accumulated third reduced current, namely 8A, 15A, and 11A, that is, charging The device A, the charging device B, and the charging device C serve as the charging device to be regulated, and the current regulating value of the charging device to be regulated is 16A.

Further, the processing unit 30 is specifically configured to calculate a third current difference value of the charging device in the third downscaling sequence, where the third current difference value is equal to the third preset value, and the The third current difference value is sequentially accumulated with the difference value obtained by subtracting the third adjustable down current, the fourth adjustable down current, and the fifth adjustable down current from the total down-regulated current. Compare, and when the sum of the third current difference is not less than the total reduced current minus the fifth adjustable reduced current, the fourth adjustable reduced current and the third adjustable reduced current When summing the obtained difference, it is obtained that the current control value of the charging device corresponding to the third current difference is 0, and it is obtained that the current control value of other charging devices in the first charging set is the third default value. For example: the total reduced current is 110A, the charging devices in the first charging set are charging device A, charging device B, and charging device C, the charging access time of charging device A is 8:01, and the charging current Is 24A, the charging connection time of charging device B is 8:30, the charging current is 31A, the charging connection time of charging device C is 9 o'clock, and the charging current is 23A, then the first downgrade sequence is the charging device A. Charging device B and charging device C, the fourth adjustable drop current is 24A-10A+31A-10A+23A-10A=48A, and the charging device in the second charging set is charging device D, charging device E. Charging device F, the fifth adjustable drop current is 41A, the charging device G, the charging device H, and the charging device I of the charging devices in the third charging set, the third adjustable drop current is 19A , 48A+41A+19A=108A<110A, that is, the sum of the fifth adjustable drop current, the fourth adjustable drop current, and the third adjustable drop current is less than the total drop current, and The sixth adjustable drop current is 24A+31A+23A=78A, 78A+41A+19A=138A>110A, that is, the sixth adjustable drop current, the fifth adjustable drop current, and the third adjustable drop current The sum of the reduced current is greater than the total reduced current. At this time, the processing unit 30 calculates that the third current difference value of the charging device in the third down-regulation sequence is 10A-0=10A, and the total down-regulation current is compared with the third adjustable down-current, so The difference between the fourth adjustable down current and the fifth adjustable down current is 110A-19A-48A-41A=2A, and 10A>2A, so the processing unit 30 further obtains the first down-regulating sequence The charging device corresponding to the accumulated third current difference, that is, the current regulation value of charging device A is 0, and the other charging devices in the first charging set, namely, charging device B and charging The current control value of the device C is the third preset value.

Further, after calculating the total boost current and the adjustable boost current, it is necessary to further select the total boost current and the adjustable boost current from the first charging set and the second charging set. The charging device to be regulated is selected from the collection and the third charging collection and the current regulating target value of the charging device to be regulated is determined.

Further, the processing unit 30 is specifically configured to select some charging devices from the third charging set as the charging devices to be regulated when the first adjustable boost current is not less than the total boost current , And obtain the current regulation target value of the charging device to be regulated in the third charging set as the third preset value. It can be understood that the first adjustable boost current is not less than the total boost current, which means that only a portion of the charging devices selected from the third charging set to increase the charging current can already meet the requirements of charging regulation. Therefore, The processing unit is specifically configured to preferentially select a charging device with a charging current of 0 in the third charging set as the charging device to be regulated. It can be understood that due to charging regulation, the charging current of some charging devices will be reduced to 0 to meet the requirements of charging regulation. Therefore, when increasing the charging current, priority is given to increasing the charging device with a charging current of 0 to meet the needs of users. Charging demand. Further, the processing unit, after screening the charging devices with the charging current of 0, selects some charging devices from the first charging set according to the sequence of charging access time as the charging devices to be regulated. Device, and obtain the current control target value of the charging device to be regulated to the third preset value.

Further, the processing unit 30 is specifically configured to form a first ramp-up sequence according to the sequence of the charging access time, and select some charging devices from the first ramp-up sequence as the charging devices to be regulated. Further, the processing unit 30 is specifically configured to sequentially accumulate and compare the first quasi-up current of the charging device in the first up-sequence with the total up-up current, and compare the results in the first step-up sequence. When the sum of the first quasi-up current is greater than the total step-up current, the charging device corresponding to the accumulated first quasi-up current except the last first quasi-up current is selected as the proposed Upgraded charging equipment. For example: the total boost current is 8A, the charging devices in the third charging set are charging device A, charging device B, and charging device C. The charging access time of charging device A is 8:1, and the charging current Is 2A, the charging connection time of charging device B is 8:30, the charging current is 9A, the charging connection time of charging device C is 9 o’clock, and the charging current is 5A, then the first ramp-up sequence is the charging device A. For charging equipment B and charging equipment C, the first adjustable boost current is 10A-2A+10A-9A+10A-5A=14A, and the first adjustable boost current is greater than the total boost current, so The processing unit 30 accumulates the first boost current of the charging device A and the first quasi boost current of the charging device B to 8A+1A=9A, which is greater than the total boost current 8A, and the accumulated The first quasi-up current is 8A and 1A, and the last first quasi-up current is 1A, then the accumulated first quasi-up current except the last first quasi-up current is 8A, and The charging device corresponding to 8A is charging device A, and the processing unit 30 selects charging device A as the charging device to be upgraded.

Further, if the total boost current is less than the first quasi boost current of any one of the charging devices in the third charging set, in this case, the charging in any one of the third charging sets Raising the charging current of the device to the third preset value will cause the real-time power load to exceed the safe current threshold. Therefore, the processing unit 30 does not select the charging device from the third charging set as the to-be-regulated charging device. Charging equipment.

Further, the processing unit 30 is specifically configured to: when the first adjustable boost current is less than the total boost current and the sum of the first adjustable boost current and the second adjustable boost current is not less than When the total current is increased, all charging devices in the third charging set are screened as the charging devices to be regulated, and the current regulation of the charging devices to be regulated in the third charging set is obtained The target value is the third preset value, and some charging devices are selected from the second charging set as the charging devices to be regulated, and the charging devices to be regulated in the second charging set are obtained. The current control target value of the device is the second preset value. It can be understood that the first adjustable boost current is less than the total boost current, indicating that when the charging currents of all charging devices in the third charging set are increased to the third preset value, there is still Surplus current, so it is necessary to continue to screen part of the charging equipment as the charging equipment to be regulated for charging regulation; further, the sum of the first adjustable boost current and the second adjustable boost current is not less than the total regulation When the current is increasing, it means that screening some charging devices from the second charging set to perform charging regulation can meet the requirements of charging regulation. Therefore, the processing unit 30 further forms a second increase sequence according to the sequence of the charging access time. , And select some charging devices from the second ascending sequence as the charging devices to be regulated.

Further, the processing unit 30 is specifically configured to sequentially add the second quasi-up current of the charging device in the second step-up sequence to the total step-up current and the first step-up current. The current difference is compared, and when the sum of the second quasi-up current is greater than the difference between the total step-up current and the first quasi-up current, select and divide the last one of the second quasi-up The charging device corresponding to the accumulated second quasi-raising current other than the rising current is used as the charging device to be raised. For example: the total boost current is 17A, the charging devices in the third charging set are charging device A, charging device B, and charging device C, the first adjustable boost current is 10A, and the charging devices in the second charging set The charging equipment of is charging equipment D, charging equipment E, and charging equipment F, and the charging access time of charging equipment D is 8:1 minute, the charging current is 11A, and the charging access time of charging equipment E is 8:30, The charging current is 13A, the charging access time of charging device F is 9 o’clock, and the charging current is 15A. Then the second adjustable boost current is 16A-11A+16A-13A+16A-15A=9A, 10A+9A= 19A>17A, that is, the sum of the first adjustable boost current and the second adjustable boost current is not less than the total boost current, and the second boost sequence is charging device D, charging device E, charging Device F, the processing unit 30 accumulates the second quasi-raised current of the charging device D and the charging device E to 5A+3A=8A, and the total raised current is the same as the first adjustable current The difference is 17A-10A=7A, 8A>7A, which is greater than the total ramp-up current, the accumulated second standard ramp-up current is 5A and 3A, and the last second standard ramp-up current is 3A, then Excluding the last second quasi-up current, the accumulated second quasi-up current is 5A, and the charging device corresponding to 5A is the charging device D, and the processing unit 30 selects the charging device D as the The charging equipment to be upgraded.

Further, if the difference between the total boost current and the first boost current is less than the second quasi boost current of any charging device in the second charging set, in this case, Increasing the charging current of any charging device in the second charging set to the second preset value will cause the real-time power load to exceed the safe current threshold. Therefore, the processing unit 30 does not receive The charging device is selected as the charging device to be regulated in the second charging set.

Further, the processing unit 30 is specifically configured to: when the sum of the first adjustable boost current and the second adjustable boost current is less than the total boost current and the first adjustable boost current, the When the sum of the second adjustable boost current and the third adjustable boost current is not less than the total boost current, select all charging devices from the third charging set as the charging devices to be regulated, and obtain The current control target value of the charging device to be regulated in the third charging set is the third preset value, and all charging devices in the second charging set are selected as the charging to be regulated Device, and obtain the current regulation target value of the charging device to be regulated in the second charging set as the second preset value, and select some charging devices from the first charging set as the The charging device to be regulated is obtained, and the current regulating target value of the charging device to be regulated in the first charging set is obtained as the first preset value. It can be understood that the sum of the first adjustable boost current and the second adjustable boost current is less than the total boost current, indicating that the charging currents of all charging devices in the third charging set are increased to At the third preset value, when the charging currents of all charging devices in the second charging set are increased to the second preset value, there is still a surplus current, so it is necessary to continue to screen some charging devices Perform charging regulation as a charging device to be regulated; further, the sum of the first adjustable boost current, the second adjustable boost current, and the third adjustable boost current is not less than the total boost current When, it is explained that further screening some charging devices from the first charging set to perform charging regulation can meet the requirements of charging regulation. Therefore, the processing unit 30 further forms a third increase sequence according to the sequence of the charging access time. And select some charging devices from the third ascending sequence as the charging devices to be regulated.

Further, the processing unit 30 is specifically configured to sequentially add the third quasi-up current of the charging device in the third step-up sequence to the total step-up current minus the first adjustable current. The boost current is compared with the difference obtained from the sum of the second adjustable boost current, and the sum of the third quasi boost current is greater than the total boost current minus the first adjustable boost current and When the difference obtained from the sum of the second adjustable boost current is selected, the charging device corresponding to the accumulated third quasi up current except the last one of the third quasi up current is selected as the proposed Upgraded charging equipment. For example: the total boost current is 26A, the charging devices in the third charging set are charging device A, charging device B, and charging device C, the first adjustable boost current is 10A, and the charging devices in the second charging set The charging equipment is charging equipment D, charging equipment E, charging equipment F, the second adjustable current is 9A, the charging equipment in the first charging set is charging equipment G, charging equipment H, charging equipment I, charging equipment The charging connection time of G is 8:1, the charging current is 30A, the charging connection time of charging device H is 8:30, the charging current is 27A, the charging connection time of charging device I is 9 o’clock, the charging current Is 25A, the third adjustable boost current is 32A-30A+32A-27A+32A-25A=14A, 10A+9A+14A=33A>26A, that is, the first adjustable boost current, the first The sum of the second adjustable boost current and the third adjustable boost current is not less than the total boost current, the third boost sequence is charging equipment G, charging equipment H, and charging equipment I, and the processing unit 30 The third quasi-boosting current of the charging device G and the charging device H is accumulated to 2A+6A=8A, and the total boosting current is the sum of the first and second quasi-boosting currents. The difference is 26A-10A-9A=7A, 8A>7A, which is greater than the total ramp-up current, the accumulated third standard ramp-up current is 2A and 6A, and the last third standard ramp-up current is 6A, Then the accumulated third quasi-up current except the last third quasi-up current is 2A, and the charging device corresponding to 2A is the charging device G, and the processing unit 30 selects the charging device G as the charging device G. Describe the charging equipment to be upgraded.

Further, if the difference obtained by subtracting the sum of the first adjustable up current and the second adjustable up current from the total boost current is less than the total value of any one charging device in the first charging set The third quasi-increasing current. In this case, increasing the charging current of any charging device in the first charging set to the first preset value will cause the real-time electrical load to exceed the safe current Therefore, the processing unit 30 does not select a charging device from the first charging set as the charging device to be regulated.

Further, the processing unit 30 is specifically configured to: when the sum of the first adjustable boost current, the second adjustable boost current, and the third adjustable boost current is less than the total boost current and the When the sum of the fourth adjustable boost current, the second adjustable boost current, and the third adjustable boost current is not less than the total boost current, all charging devices from the third charging set are selected as all charging devices. Describe the charging equipment to be regulated, and obtain that the current regulation target value of part of the charging equipment to be regulated in the third charging set is the third preset value, and that of the other part of the charging equipment The current control target value is the second preset value, and all charging devices in the second charging set are screened as the charging devices to be regulated, and the proposed regulation in the second charging set is obtained The current regulation target value of the charging device is the second preset value, and all the charging devices in the first charging set are selected as the charging devices to be regulated, and the charging devices in the first charging set are obtained The current regulation target value of the charging device to be regulated is the first preset value. It can be understood that the sum of the first adjustable boost current, the second adjustable boost current, and the third adjustable boost current is less than the total boost current, which means that all the components in the third charging set are When the charging currents of the charging devices are all increased to the third preset value, the charging currents of all the charging devices in the second charging set are increased to the second preset value, and the first When the charging currents of all charging devices in the charging set are increased to the first preset value, there is still a surplus current. Therefore, it is necessary to continue to adjust the current control target values of some charging devices to perform charging control; further, the When the sum of the fourth adjustable boost current, the second adjustable boost current, and the third adjustable boost current is not less than the total boost current, it means that the third charging set is further added to the The charging current of part of the charging equipment to be regulated is adjusted to the second preset value, and the charging current of the other part of the charging equipment to be regulated is adjusted to the third preset value to meet the requirements of charging regulation. Therefore, The processing unit 30 is specifically configured to calculate a fourth current difference value of the charging device in the first ramp-up sequence, where the fourth current difference value is equal to the difference between the second preset value and the third preset value. The difference value, and the fourth current difference value is sequentially added to the total boost current minus the first adjustable boost current, the second adjustable boost current, and the third adjustable boost current And the difference value obtained, and when the sum of the fourth current difference value is greater than the total boost current minus the first adjustable boost current, the second adjustable boost current and the first The difference value obtained by the sum of the three adjustable boost currents yields the current control value of the charging device corresponding to the fourth current difference value other than the last fourth current difference value as the second preset value, And it is obtained that the current control value of other charging devices in the third charging set is the third preset value.

The second adjustable-up sequence is charging device A, charging device B, and charging device C. The current is 9A, the charging device G, the charging device H, and the charging device I of the charging device in the first charging set, the third adjustable boost current is 14A, 14A+9A+14A=37A<45A, that is, The sum of the first adjustable boost current, the second adjustable boost current, and the third adjustable boost current is less than the total boost current, and the fourth boost current is 16A-2A+16A- 9A+16A-5A=32A, 32A+14A+9A=55A>45A, that is, the sum of the second adjustable rise current, the third adjustable rise current and the fourth adjustable rise current is greater than the said Total boost current. At this time, the processing unit 30 obtains that the fourth current difference of the charging equipment in the first ramp-up sequence is 16A-10A=6A, and the total ramp-up current is compared with the first ramp-up current, The difference between the second adjustable boost current and the third adjustable boost current is 45A-14A-9A-14A=8A, 6A+6A=12A>8A, and the accumulated fourth standard boost current 6A and 6A, the last fourth quasi-raising current is 6A, and the accumulated fourth quasi-raising current except the last fourth quasi-raising current is 6A, and the charging equipment corresponding to 6A is The charging device A obtains that the current control value of the charging device A is the second preset value, and the current control value of the charging device B and the charging device C is the third preset value.

Further, if the total boost current minus the first adjustable boost current, the second adjustable boost current and the third adjustable boost current, the difference is less than the third charging current The fourth current difference in the set. In this case, increasing the charging current of any charging device in the third charging set to the second preset value will cause the real-time power load to exceed all The safe current threshold value, therefore, the processing unit 30 does not select a charging device whose current regulation value is the second preset value from the third charging set as the charging device to be regulated, that is, the processing unit 30 selects the charging device to be regulated from All the charging devices in the third charging set are selected as the charging devices to be regulated, and the current regulation value of all the charging devices in the third charging set is the third preset value.

Further, the processing unit 30 is specifically configured to: when the sum of the fourth adjustable boost current, the third adjustable boost current, and the second adjustable boost current is less than the total boost current and the When the sum of the fifth adjustable boost current, the fourth adjustable boost current, and the third adjustable boost current is not less than the total boost current, all charging devices from the third charging set are selected as all charging devices. Describe the charging device to be regulated, and obtain the current regulation target value of the charging device to be regulated in the third charging set to the second preset value, and select all from the second charging set The charging device is used as the charging device to be regulated, and it is obtained that the current regulation target value of part of the charging device to be regulated in the second charging set is the first preset value, and the other part of the charging device to be regulated is The current control target value of the charging device is the second preset value, and all charging devices in the first charging set are selected as the charging devices to be regulated, and all the charging devices in the first charging set are obtained. The current regulation target value of the charging device to be regulated is the first preset value. It can be understood that the sum of the fourth adjustable boost current, the second adjustable boost current, and the third adjustable boost current is less than the total boost current, which means that all the components in the third charging set are When the charging currents of the charging devices are all increased to the second preset value, the charging currents of all charging devices in the second charging set are increased to the second preset value, and the first When the charging currents of all charging devices in the charging set are increased to the first preset value, there is still a surplus current. Therefore, it is necessary to continue to adjust the current control target values of some charging devices to perform charging control; further, the When the sum of the fifth adjustable boost current, the fourth adjustable boost current, and the third adjustable boost current is not less than the total boost current, it means that on the basis of the above, the second charging set The charging current of part of the charging equipment to be regulated is adjusted to the first preset value, and the charging current of the other part of the charging equipment to be regulated is adjusted to the second preset value to meet the requirements of charging regulation. The processing unit 30 is specifically configured to subtract the second quasi-up current from the fifth quasi-up current of the charging device in the second quasi-up sequence to obtain a fifth current difference, and then The fifth current difference value is sequentially accumulated and compared with the difference value obtained by subtracting the second adjustable up current, the third adjustable up current and the fourth adjustable up current from the total boosted current , And when the sum of the fifth current difference is greater than the total boost current minus the second adjustable boost current, the third adjustable boost current and the fourth adjustable boost current to obtain The difference value is derived from the current control value of the charging device corresponding to the fifth current difference value other than the last fifth current difference value, and the first preset value is obtained, and the second charging set is obtained The current control value of other charging devices in the charging device is the second preset value.

For example: the total boost current is 80A, the charging devices in the third charging set are charging device A, charging device B, and charging device C, the fourth adjustable boost current is 32A, and the second charging set The charging equipment in the collection is charging equipment D, charging equipment E, and charging equipment F. The charging access time of charging equipment D is 8: 1 minute, the charging current is 11A, and the charging connection time of charging equipment E is 8: 30 minutes. , The charging current is 13A, the charging access time of the charging device F is 9 o'clock, and the charging current is 15A, then the second ramp-up sequence is charging device D, charging device E, and charging device F. The second adjustable The rising current is 16A-11A+16A-13A+16A-15A=9A, the fifth adjustable rising current is 32A-11A+32A-13A+32A-15A=57A, and the charging equipment in the first charging set For charging equipment G, charging equipment H, and charging equipment I, the third adjustable boost current is 14A, 32A+9A+14A=55A<80A, that is, the fourth adjustable boost current and the second adjustable boost current The sum of the boost current and the third adjustable boost current is less than the total boost current, and 57A+33A+14A=104A>80A, that is, the fifth adjustable boost current and the fourth adjustable boost current The sum of the third step-up current and the third step-up current is greater than the total step-up current. At this time, the processing unit 30 obtains that the fifth current difference between the charging devices in the second ramp-up sequence is 32A-16A=16A, and the total ramp-up current is compared with the second ramp-up current, The difference between the third adjustable boost current and the fourth adjustable boost current is 80A-32A-14A-9A=25A, 16A+16A=32A>25A, and the accumulated fifth quasi boost current 16A and 16A, the last fifth quasi-raising current is 16A, then the accumulated fifth quasi-raising current except the last fifth quasi-raising current is 16A, and the charging equipment corresponding to 16A is Charging device D, the processing unit 30 obtains that the current control value of the charging device D is the first preset value, and the current control value of the charging device E and the charging device F is the second default value.

Further, if the total boost current minus the second adjustable boost current, the sum of the third adjustable boost current and the fourth adjustable boost current is smaller than the second The fifth current difference in the charging set. In this case, increasing the charging current of any charging device in the second charging set to the first preset value will cause the real-time power load to exceed The safe current threshold, therefore, the processing unit 30 does not select a charging device whose current regulation value is the first preset value from the second charging set as the charging device to be regulated, that is, the processing unit 30 All the charging devices in the second charging set are selected as the charging devices to be regulated, and the current regulating value of all the charging devices in the second charging set is the second preset value.

Further, the processing unit 30 is specifically configured to: when the sum of the fifth adjustable boost current, the fourth adjustable boost current, and the third adjustable boost current is less than the total boost current and the When the sum of the sixth adjustable boost current, the fifth adjustable boost current, and the third adjustable boost current is not less than the total boost current, all charging devices from the third charging set are selected as all charging devices. Describe the charging equipment to be regulated, and obtain that the current control target value of part of the charging equipment to be regulated in the third charging set is the first preset value, and that of the other part of the charging equipment to be regulated The current control target value is the second preset value, and all charging devices in the second charging set are screened as the charging devices to be regulated, and the proposed regulation in the second charging set is obtained The current control target value of the charging device is the first preset value, and all charging devices in the first charging set are screened as the charging devices to be regulated, and all the charging devices in the first charging set are obtained. The current regulation target value of the charging device to be regulated is the first preset value. It can be understood that the sum of the fifth adjustable boost current, the fourth adjustable boost current, and the third adjustable boost current is less than the total boost current, indicating that all charging devices in the third charging set When the charging currents of all the charging currents are increased to the second preset value, the charging currents of all the charging devices in the second charging set are increased to the first preset value, and the first charging set When the charging currents of all the charging devices in the charging device are increased to the first preset value, there is still a surplus current. Therefore, it is necessary to continue to adjust the current control target value of some charging devices to perform charging control; The sum of the adjustable boost current, the fifth adjustable boost current, and the fourth adjustable boost current is not less than the total boost current, indicating that the part of the third charging set is further simulated on the basis of the above. The charging current of the regulated charging device is adjusted to the first preset value, and the charging current of the other part of the charging device to be regulated is adjusted to the second preset value to meet the requirements of charging regulation. Therefore, the processing unit 30 further calculates a sixth current difference value of the charging device in the first ramp-up sequence, where the sixth current difference value is equal to the difference between the first preset value and the second preset value, and The sixth current difference value is sequentially accumulated and the difference obtained by subtracting the fifth adjustable up current, the fourth adjustable up current and the third adjustable up current from the total boosted current Value, and when the sum of the sixth current difference value is greater than the total boost current minus the fifth adjustable boost current, the fourth adjustable boost current, and the third adjustable boost current The difference value obtained from the sum of the current values of the charging equipment corresponding to the sixth current difference value other than the last sixth current difference value is the first preset value, and the first preset value is obtained. The current control value of other charging devices in the third charging set is the second preset value.

For example: the total boost current is 130A, the charging devices in the third charging set are charging device A, charging device B, and charging device C. The charging access time of charging device A is 8:1, and the charging current Is 2A, the charging connection time of charging device B is 8:30, the charging current is 9A, the charging connection time of charging device C is 9 points, the charging current is 5A, and the fourth adjustable boost current is 32A, The first step-up sequence is charging device A, charging device B, and charging device C, the charging devices in the second charging set are charging device D, charging device E, and charging device F. The fifth step-up sequence is charging device A, charging device B, and charging device C. The current is 57A, the charging device G, the charging device H, and the charging device I of the charging device in the first charging set, the third adjustable boost current is 14A, 32A+57A+14A=103A<130A, that is, The sum of the fifth adjustable boost current, the fourth adjustable boost current, and the third adjustable boost current is less than the total boost current, and the sixth boost current is 32A-2A+32A- 9A+32A-5A=80A, 80A+57A+14A=151A>130A, that is, the sum of the sixth adjustable rise current, the fifth adjustable rise current and the third adjustable rise current is greater than the said Total boost current. At this time, the processing unit 30 obtains that the sixth current difference of the charging equipment in the first ramp-up sequence is 32A-16A=16A, and the total ramp-up current is compared with the fifth ramp-up current, The difference between the fourth adjustable boost current and the third adjustable boost current is 130A-57A-32A-14A=27A, 16A+16A=32A>27A, the accumulated sixth quasi boost current 16A and 16A, the last sixth quasi-raising current is 16A, and the accumulated sixth quasi-raising current except the last sixth quasi-raising current is 16A. The charging equipment corresponding to 16A is Charging device A, the processing unit 30 obtains that the current control value of the charging device A is the first preset value, and the current control value of the charging device B and the charging device C is the second default value.

Further, if the difference between the total boost current minus the fifth adjustable boost current, the sum of the fourth adjustable boost current and the third adjustable boost current is smaller than the first The sixth current difference in the charging set. In this case, increasing the charging current of any charging device in the first charging set to the first preset value will cause the real-time power load to exceed The safe current threshold, therefore, the processing unit 30 does not select a charging device whose current regulation value is the first preset value from the third charging set as the charging device to be regulated, that is, the processing unit 30 All the charging devices in the third charging set are selected as the charging devices to be regulated, and the current regulating value of all the charging devices in the third charging set is the second preset value.

Further, the processing unit 30 selects the charging device to be regulated from the first charging set, the second charging set, and the third charging set, and obtains the current of the charging device to be regulated After regulating the target value, the charging device to be regulated and the corresponding current regulating target value are sent to the regulating unit 40, and the regulating unit 40 charges the charging device to be regulated according to the current regulating target value. The current is adjusted to the corresponding current control target value, thereby ensuring that the power grid is in a safe state and ensuring that the charging device is efficiently charged.

Since the charging control system of the present invention sets the current control target value to any one of the first preset value, the second preset value, the third preset value, and 0, it can quickly and accurately calculate according to the current current of the charging device Multiple adjustable currents of the current charging device, and then select an adjustable current that best matches the total adjustable current from the multiple adjustable currents according to the total adjustable current, so that the adjustable current can be selected according to the adjustable current The charging device to be regulated is quickly screened out from the first set, the second set, and the third set, and then the current to be regulated of the charging device to be regulated is accurately calculated based on the adjustable current, and the current to be regulated is determined for the regulated current. The charging equipment is controlled in batches, which not only guarantees the accuracy of the regulation, but also ensures the efficiency of the regulation. Only one charge regulation is required to meet the community current safety threshold requirements, and the regulation process is very precise and rapid. Moreover, when reducing the charging current in this case, the charging devices in the charging set with the higher charging current are sequentially selected as the charging devices to be regulated, and the charging current is sequentially reduced by one current level within the total regulated current range to calculate the available Adjusting the current will not reduce the charging equipment in the charging set with the lower charging current when the total control current is low, nor will it directly adjust the charging set in the charging set with the higher charging current when the total control current is higher. The charging current of the charging equipment is reduced to 0, thus ensuring that all charging equipment can maintain a relatively high charging efficiency, and the intelligent charging control is realized.

Please refer to FIG. 2, another preferred embodiment of the present invention provides a charging method. The charging method is applied to any embodiment or permutation and combination of the foregoing charging control system, including the following steps:

Step S210: Obtain a real-time power load, where the real-time power load includes electric current used by residents and charging current of the charging device.

In this embodiment, in the community, in order to facilitate charging by residents, a charging device is provided near the community parking space so that the user can use the charging device for charging after parking the vehicle in the parking space. Further, the charging devices are all connected to a charging control system to receive a control command from the charging control system to perform charging control.

Further, after the charging device is connected to the charging control system, before performing charging control, it is necessary to obtain the real-time power load of the community and load the real-time power, the real-time power load includes the current of the residents and the charging of the charging device The current, specifically, in this embodiment, the real-time power load is the sum of the residential electricity current and the charging current of the charging device.

Further, since the electric current of the residential power line and the charging current of the charging device are in a changing state as the residential electric and the vehicle are charged, the real-time electric load obtained is also in a changing state, and it may follow As the electric current of residents or the charging current of charging equipment increases and exceeds the upper limit of the circuit line of the community, accidents such as tripping may occur. For example, if the acquired residential electricity current is 1000A, and the charging current of the charging device is 500A, then the real-time power load is 1000A+500=1500A.

Step S220: Compare the real-time power load and the safe current threshold to obtain a comparison result.

Further, after obtaining the real-time electric load, it is necessary to compare the real-time electric load with a pre-stored safe current threshold and obtain a comparison result. Further, the comparison result includes that the real-time electric load is not less than the safe current threshold, or the real-time electric load is less than the safe current threshold.

It can be understood that because the community power line has a rated current, in order to prevent the community power current from exceeding the rated current setting a safety factor, the safe current threshold is obtained based on the rated current and the safety factor, and When the real-time electric load exceeds the safe current threshold, charging control will be performed to prevent the real-time electric load of the community from reaching or exceeding the rated current, which may cause a trip or power failure. Further, in this embodiment, the safe current threshold is the product of the rated current of the community power grid and a safety factor. For example, if the rated current of the community power grid is 2000A, and the safety factor is 0.9, the safe current threshold is 2000A*0.9=1800A.

Step S230: Calculate the total regulated current and the at least one adjustable current of the charging device according to the comparison result, and screen the charging device to be regulated according to the total regulated current and the at least one adjustable current, and obtain the The current control target value of the charging device to be regulated, where the current control target value includes at least one of a first preset value, a second preset value, a third preset value, and zero.

Further, the total regulated current is the total current that needs to be reduced by the charging equipment connected in the grid when the real-time electric load is not less than the safe current threshold, or the real-time electric load is less than the safe current threshold At that time, the total current that the charging equipment connected in the grid needs to increase.

Further, in order to maintain the stability of the community power load, it is necessary to reduce or increase the charging current of the charging device according to the real-time power load condition of the community power grid. Therefore, the total regulated current needs to be calculated according to the comparison result. Further, in this embodiment, the total regulated current includes a total regulated current or a total regulated current. The total reduced current is the sum of the charging currents required to be reduced by all charging devices in the power grid when the real-time electrical load is greater than the safe current threshold; the total reduced current is the sum of the real-time electrical load less than When the safe current threshold is set, the sum of the charging currents that all charging devices in the power grid need to increase. For example: when the real-time power load is 20A higher than the safe current threshold, the total regulated current is the total reduced current, and the total reduced current is 20A; the real-time power load is lower than the safe current At 10A, the total regulated current is the total ramp-up current, and the total ramp-up current is 10A.

Further, in order to determine how to perform charging control, it is necessary to further calculate the adjustable current of the charging device, where the adjustable current is that all the charging devices in the power grid adjust the charging current to the second preset value , The sum of at least one of the third preset value and 0, the charging current that needs to be reduced, or the charging current is increased to the third preset value, the second preset value, and the first At least one of the preset values is the sum of the charging currents that need to be increased. It can be understood that because the charging current of the charging device needs to be adjusted or adjusted according to the real-time power load, the adjustable current includes an adjustable down current and an adjustable up current, and the adjustable down current is the same as the total adjusted down current. The current corresponding setting is used as a basis for reducing the charging current of the charging device, and the adjustable current reduction is that all the charging devices in the power grid reduce the charging current to the second preset value, the third The sum of at least one charging current that needs to be reduced by a preset value and 0; the adjustable boost current is that all the charging devices in the power grid increase the charging current to the third preset value, the first The sum of the charging current required to be increased by any one of the two preset values and the first preset value. Further, the adjustable boost current and the total boost current are set correspondingly to serve as a basis for boosting the charging current of the charging device. For example, the current power grid includes one charging device A, and the charging current of the charging device A is 31A. In this embodiment, there are three current levels, namely 32A, 16A, and 10A. Then the adjustable boost current is 1A, the adjustable drop current is 15A, 21A or 31A.

Further, when the received comparison result is that the real-time power load is not less than the safe current threshold, it indicates that the current community load is relatively high, and the charging current of the charging device needs to be reduced. At this time, the total power load needs to be calculated. Adjust the current, and at the same time, in order to determine how to perform charging regulation, it is also necessary to calculate the adjustable drop current of the charging device, so as to screen the charging device to be regulated according to the total drop current and the adjustable drop current and obtain the result The current regulation target value of the charging equipment to be regulated is described.

Further, when the received comparison result is that the real-time power load is less than the safe current threshold, it indicates that the current community load is low, and the charging current of the charging device needs to be increased. At this time, the total adjustment needs to be calculated. At the same time, in order to determine how to perform charging regulation, it is also necessary to calculate the adjustable boost current of the charging device, so as to screen the charging device to be regulated according to the total boost current and the adjustable boost current and obtain the The current regulation target value of the charging device to be regulated.

Further, in this embodiment, the charging device is further divided into at least one charging set according to the charging current of the charging device, and selected from the charging set according to the total regulation current and the adjustable current As the charging device to be regulated, it can be understood that the charging device to be regulated is a charging device that needs to increase or decrease the charging current. Further, in this embodiment, the charging set includes a first charging set, a second charging set, and a third charging set. When dividing, the charging current is further not greater than the first preset value and greater than the second charging set. The charging devices of the preset value are classified into the first charging set, and the charging devices with the charging current not greater than the second preset value and greater than the third preset value are classified into the second charging set, And divide the charging current not greater than the third preset value into the third charging set. In this embodiment, the first preset value is 32A, the second preset value is 16A, and the third preset value is 10A. It can be understood that dividing the charging device into different charging sets based on the difference in charging current facilitates the rapid calculation of the level of the adjustable current and the comparison of the adjustable current with the total regulated current so as to quickly filter out the proposed model. And calculate the current regulation target value of the charging device to be regulated. For example: the power grid includes a charging device a, a charging device b, and a charging device c. The charging current of the charging device a is 30A, the charging current of the charging device b is 28a, and the charging current of the charging device c is 25A, since the three current values of 30A, 28A, and 25A are all greater than 16A and less than 32A, the charging device a, the charging device b, and the charging device c are all divided into the first charging set; in the power grid Including charging device d, charging device e, and charging device f. The charging current of the charging device d is 22A, the charging current of the charging device e is 20A, and the charging current of the charging device c is 15A. The two current values are greater than 16A and less than 32A, so the charging device d and the charging device e are classified into the first charging set. Since 15A is greater than 10A and less than 16A, the charging device f is classified into the second charging set The power grid includes charging equipment A, charging equipment B, charging equipment C, charging equipment D, charging equipment E, the charging current of the charging equipment A is 20A, the charging current of the charging equipment B is 25A, the If the charging current of the charging device C is 15A, the charging current of the charging device D is 9A, and the charging current of the charging device E is 8A, the processing unit 30 divides the charging device A and the charging device B into In the first charging set, the charging device C is classified into the second charging set, and the charging device D and the charging device E are classified into the third charging set. In summary, since the current value of the charging equipment in the power grid is between 0-32A, when dividing the charging set, the charging equipment in the power grid can be divided into at least one charging set.

Further, further, in this embodiment, when the charging device performs current increase, the current increase target value is the first preset value, the second preset value, and the third preset value. Therefore, when calculating When the current is adjustable, the adjustable current can be obtained according to the first preset value, the second preset value, the third preset value and the current current. Further, in this embodiment, the charging devices of the first charging set, the second charging set, and the third charging set increase the charging current according to the third charging set, the second charging set, The order of the first charging set increases the charging current in turn. For example: when increasing the charging current, the charging current of the charging device of the third charging set is first increased to the third preset value, and then the charging current of the charging device of the second charging set is increased to the specified value. According to the second preset value, the charging current of the charging device of the first charging set is increased to the first preset value, and the charging current of the charging device of the third charging set is increased to the first preset value. The second preset value, and finally the charging current of the charging device of the third charging set is increased to the first preset value.

Further, when the first adjustable drop current is not less than the total drop current, select some charging devices from the first charging set as the charging devices to be regulated, and obtain the first The current regulation target value of the charging device to be regulated in the charging set is the second preset value. It can be understood that if the first adjustable drop current is not less than the total regulation current, it means that the regulation requirement can be met by reducing the part of the charging equipment in the first charging set to the second preset value. Therefore, according to the sequence of the charging access time, some charging devices from the first charging set may be selected as the charging devices to be regulated. Further, it is specifically configured to form the charging devices in the first charging set into a first down-regulation sequence according to the sequence of charging access time, and select some charging devices from the first down-regulation sequence as the proposed Regulated charging equipment. Further, it is specifically configured to sequentially accumulate the first standard reduced current of the charging device in the first reduced sequence to compare with the total reduced current, and reduce the current in the first standard When the sum is not less than the total reduced current, the accumulated charging device corresponding to the first quasi-reduced current is selected as the charging device to be regulated. For example: the total reduced current is 20A, the charging devices in the first charging set are charging device A, charging device B, and charging device C, the charging access time of charging device A is 8:01, and the charging current Is 24A, the charging connection time of charging device B is 8:30, the charging current is 31A, the charging connection time of charging device C is 9 o’clock, and the charging current is 27A, then the first downgrade sequence is the charging device A. Charging device B and charging device C, the first adjustable drop current is 8A+15A+11A=34A, the first adjustable drop current is greater than the total drop current, the charging device A and If the first quasi-dropped current of the charging device B is accumulated to 8A+15A=23A, which is greater than the total reduced current of 20A, the charging devices corresponding to 8A and 15A are selected from the first down-regulated sequence, namely Charging device A and charging device B are used as the charging devices to be regulated; if the total reduced current is 33A, the first standard reduced current of charging device A and charging device B is accumulated to 8A+15A=23A, If it is less than the total reduced current of 33A, then continue to accumulate the first quasi-reduced current of the charging device C to 8A+15A+11A=34A, and if it is greater than the total reduced current of 33A, start from the first adjusted current In the descending sequence, the charging devices corresponding to the accumulated third quasi-decreasing current, namely 8A, 15A, and 11A, namely, charging device A, charging device B, and charging device C are selected as the charging devices to be regulated, and The current regulation value of the charging device to be regulated is 16A.

Further, it is specifically used when the first adjustable drop current is less than the total drop current and the sum of the first adjustable drop current and the second adjustable drop current is not less than the total drop current When, select all the charging devices from the first charging set as the charging devices to be regulated, and obtain the current regulation target value as the second preset value, and select it from the second charging set Part of the charging equipment is selected as the charging equipment to be regulated, and the current regulation target value is obtained as the third preset value. It can be understood that the first adjustable drop current is less than the total drop current, indicating that reducing the charging current of the charging devices in the first charging set to the second preset value still cannot satisfy current regulation Demand; further, the sum of the first adjustable drop current and the second adjustable drop current is not less than the total drop current, which means that the charging current of the charging device in the first charging set is reduced to The second preset value then reduces the selected part of the charging devices in the second charging set to the third preset value to meet the current regulation requirements, so all charging devices in the first charging set are selected And some of the charging devices in the second charging set are used as the charging devices to be regulated, and the current regulating target value of the charging devices to be regulated in the first charging set is set to the second preset value , Setting the current regulation target value of the charging device to be regulated of the charging device in the second charging set to the third preset value can meet the current regulation requirement.

Further, it is specifically configured to form the charging devices in the second charging set into a second downscaling sequence according to the sequence of the charging access time, and to select some of the charging devices from the second downscaling sequence as the proposed Regulated charging equipment. Further, it is specifically configured to sequentially accumulate the second quasi-adjusted down current of the charging device in the second down-regulated sequence with the difference between the total down-regulated current and the first adjustable down current. Compare, and select the one corresponding to the accumulated second quasi-down current when the sum of the second quasi-down current is not less than the difference between the total down-down current and the first quasi-down current The charging device serves as the charging device to be regulated. For example: the total reduced current is 35A, the charging devices in the first charging set are charging device A, charging device B, and charging device C, the first adjustable falling current is 30A, and the charging devices in the second charging set The charging equipment of is charging equipment D, charging equipment E, and charging equipment F, and the charging access time of charging equipment D is 8:1 minute, the charging current is 11A, and the charging access time of charging equipment E is 8:30, The charging current is 13A, the charging access time of charging device F is 9 o’clock, and the charging current is 15A. Then the second adjustable drop current is 1A+3A+5A=9A, 30A+9A=39A>35A, that is, The sum of the first adjustable drop current and the second adjustable drop current is not less than the total drop current, and the second drop sequence is charging device D, charging device E, and charging device F. The second quasi-reduced current of the charging device D and the charging device E is accumulated to 1A+3A=4A, and the difference between the total reduced current and the first adjustable-reduced current is 35A-30A=5A, 4A <5A, so the second quasi-dropping current of the charging device F is further accumulated as 1A+3A+5A=9A, and 9A>5A, then the second quasi-dropping current that has been accumulated is further selected from the second down-down sequence The second quasi-decreasing current, that is, the charging devices corresponding to 1A, 3A, and 5A, that is, charging device D, charging device E, and charging device F are used as the charging device to be regulated, and the current of the charging device to be regulated is regulated The value is 10A.

Further, when the sum of the first adjustable drop current and the second adjustable drop current is less than the total drop current and the first adjustable drop current, the second adjustable drop current and When the sum of the third adjustable drop current is not less than the total drop current, all charging devices in the first charging set are selected as the charging devices to be regulated, and the current control target value is obtained Is the second preset value, and selects all charging devices from the second charging set as the charging devices to be regulated, and obtains the current regulation target value as the third preset value, and Part of the charging devices are selected from the third charging set as the charging devices to be regulated, and it is obtained that the current regulation target value is 0. It can be understood that the sum of the first adjustable drop current and the second adjustable drop current is less than the total drop current, indicating that the currents of all charging devices in the first rechargeable set are adjusted to all levels. The second preset value and reducing the current of the charging equipment in the second charging set to the third preset value still cannot meet the demand of current regulation; further, the first adjustable current reduction, If the sum of the second adjustable drop current and the third adjustable drop current is not less than the total drop current, it means that the current of all charging devices in the first rechargeable set is adjusted to all levels. The second preset value and the current of the charging device in the second charging set is reduced to the third preset value, and then some charging devices in the third charging set are selected as the intended charging device , And setting the current regulation value of the device to be charged in the third charging set to 0 can meet the current regulation requirement.

Further, it is specifically configured to form the charging devices in the third charging set into a third downscaling sequence according to the sequence of charging access time, and to select some of the charging devices from the third downscaling sequence as the proposed Regulated charging equipment. Further, it is specifically configured to sequentially accumulate the third quasi-tune-down current of the charging device in the third tune-down sequence with the total tune-down current minus the first tune-down current and the The difference obtained from the sum of the second adjustable drop current is compared, and the sum of the third standard drop current is not less than the total drop current minus the first adjustable drop current and the second When adjusting the difference obtained from the sum of the adjustable drop currents, the charging device corresponding to the accumulated third standard drop current is selected as the charging device to be regulated. For example: the total reduced current is 55A, the charging devices in the first charging set are charging device A, charging device B, and charging device C, the first adjustable falling current is 30A, and the charging devices in the second charging set The charging equipment of is charging equipment D, charging equipment E, and charging equipment F, the second adjustable drop current is 8A, charging equipment G, charging equipment H, and charging equipment I of the charging equipment in the third charging set, And the charging connection time of the charging device G is 8:1, the charging current is 9A, the charging connection time of the charging device H is 8:30, the charging current is 6A, and the charging connection time of the charging device I is At 9 o'clock, the charging current is 4A, then the third adjustable drop current is 9A+6A+4A=19A, 30A+8A+19=57A>55A, that is, the sum of the first adjustable drop current, the second adjustable drop current and the third adjustable drop current is not less than the total drop current, The third reduction sequence is charging device G, charging device H, and charging device I. The third quasi reduction current of said charging device G and said charging device H is accumulated to 9A+6A=15A, and the total reduction is The difference between the current and the first adjustable drop current and the second adjustable drop current is 55A-30A-8A=17A, 15A<17A, so the processing unit 30 further calculates the first step of the charging device I The accumulated three-level down current is 9A+6A+4A=19A, and 19A>17A, then the third down-down sequence is further selected from the third down-down sequence and the accumulated third-level down current, namely 9A, 6A, and 4A The corresponding charging devices, namely, the charging device G, the charging device H, and the charging device I are used as the charging device to be regulated, and the current regulating value of the charging device to be regulated is 0.

All charging devices in the set are screened as the charging devices to be regulated, and the current regulation target value is obtained as the third preset value, and all charging devices in the third charging set are screened as the intended charging devices. The charging device is regulated, and the current regulation target value is 0. It can be understood that the sum of the first adjustable drop current, the second adjustable drop current, and the third adjustable drop current is less than the total drop current. The charging currents of all charging devices are reduced to the second preset value, the charging currents of all charging devices in the second charging set are reduced to the third preset value, and the third charging The charging current of all the charging devices in the set is reduced to 0 and still cannot meet the requirements of current regulation; further, the fourth adjustable drop current, the second adjustable drop current, and the third adjustable drop current If the sum is not less than the total reduced current, it means that the charging current of some of the charging devices in the first charging set is reduced to the third preset value, and the charging current of the other part of the charging device is reduced to the specified value. The second preset value, and adjust the charging currents of all the charging devices in the second charging set to the third preset value, and reduce the charging currents of all the charging devices in the third charging set Adjusting to 0 can meet the demand of current regulation.

The charging device is used as the charging device to be regulated, and it is obtained that the current regulating target value is 0. It can be understood that if the sum of the fourth adjustable drop current, the second adjustable drop current, and the third adjustable drop current is less than the total drop current, it means that the first charging set is set The charging currents of all the charging devices in the charging set are reduced to the third preset value, the charging currents of all the charging devices in the second charging set are reduced to the third preset value, and the first The charging current of all the charging devices in the three charging set is reduced to 0 but the current regulation is not required; further, the charging currents of all the charging devices in the first charging set are adjusted to the third preset value, Adjust the charging current of some charging devices in the second charging set to 0, and adjust the charging current of another part of the charging devices to the third preset value, and charge all the charging devices in the third charging set When the current is adjusted down to 0, the demand for current control is satisfied.

At this time, the second current difference of the charging equipment in the second down-regulation sequence is calculated to be 10A-0=10A, and the total down-regulation current is the same as the second adjustable down-current and the third adjustable down-current. The difference between the lowering current and the fourth adjustable lowering current is 90A-48A-8A-19A=15A, 10A+10A=20A>15A, so it is further obtained that the sum of the accumulated value in the second lowering sequence The current control value of the charging device corresponding to the second current difference, that is, charging device D and charging device E, is 0, and the current control value of other charging devices in the second charging set, namely, charging device F is obtained Is the third preset value.

Further, the sum of the fifth adjustable drop current, the fourth adjustable drop current, and the third adjustable drop current is less than the total drop current and the sixth adjustable drop current, When the sum of the fifth adjustable drop current and the third adjustable drop current is not less than the total drop current, select all charging devices from the first charging set as the charging devices to be regulated, and It is obtained that the current control target value of the charging equipment in the first charging set is the third preset value, and the current control target value of the other part of the charging equipment is 0, and all are selected from the second charging set The charging device is used as the charging device to be regulated, and the current control target value is obtained as 0, and all charging devices are selected from the third charging set as the charging device to be regulated, and the The current control target value is 0. It can be understood that if the sum of the fifth adjustable drop current, the fourth adjustable drop current, and the third adjustable drop current is less than the total drop current, it means that the first charging set The charging currents of all charging devices in the second charging set are adjusted to the second preset value, the charging currents of all charging devices in the second charging set are adjusted to 0, and all the charging currents in the third charging set are adjusted to 0. The charging current of the charging device is reduced to 0, but the current adjustment is not possible; further, the charging current of some of the charging devices in the first charging set is adjusted to 0, and the charging current of the other part of the charging device is adjusted to the required value. According to the third preset value, the charging current of all the charging devices in the second charging set is adjusted to 0, and the charging current of all the charging devices in the third charging set is adjusted to 0.

For example: the total reduced current is 110A, the charging devices in the first charging set are charging device A, charging device B, and charging device C, the charging access time of charging device A is 8:01, and the charging current Is 24A, the charging connection time of charging device B is 8:30, the charging current is 31A, the charging connection time of charging device C is 9 o'clock, and the charging current is 23A, then the first downgrade sequence is the charging device A.

At this time, the third current difference of the charging equipment in the third down-regulating sequence is calculated to be 10A-0=10A, and the total down-regulating current is the same as the third adjustable down current and the fourth adjustable down current. The difference between the lowering current and the fifth adjustable lowering current is 110A-19A-48A-41A=2A, and 10A>2A, so it is further obtained that the first lowering sequence and the accumulated third current The current control value of the charging device corresponding to the difference, that is, the current control value of the charging device A is 0, and the current control value of the other charging devices in the first charging set, namely, the charging device B and the charging device C is obtained. Three preset values.

Further, when the first adjustable boost current is not less than the total boost current, select some charging devices from the third charging set as the charging devices to be regulated, and obtain the third The current regulation target value of the charging device to be regulated in the charging set is the third preset value. It can be understood that the first adjustable boost current is not less than the total boost current, which means that only a portion of the charging devices selected from the third charging set to increase the charging current can already meet the requirements of charging regulation. Therefore, The processing unit is specifically configured to preferentially select a charging device with a charging current of 0 in the third charging set as the charging device to be regulated. It can be understood that due to charging regulation, the charging current of some charging devices will be reduced to 0 to meet the requirements of charging regulation. Therefore, when increasing the charging current, priority is given to increasing the charging device with a charging current of 0 to meet the needs of users. Charging demand. Further, the processing unit, after screening the charging devices with the charging current of 0, selects some charging devices from the first charging set according to the sequence of charging access time as the charging devices to be regulated. Device, and obtain the current control target value of the charging device to be regulated to the third preset value.

Further, it is specifically configured to sequentially accumulate the first quasi-up current of the charging device in the first step-up sequence and compare it with the total quasi-up current, and to increase the current in the first quasi-up sequence. When the sum is greater than the total boost current, the charging device corresponding to the accumulated first quasi-up current except the last first quasi-up current is selected as the charging device to be boosted . For example: the total boost current is 8A, the charging devices in the third charging set are charging device A, charging device B, and charging device C. The charging access time of charging device A is 8:1, and the charging current 2A, the charging connection time of charging device B is 8:30, the charging current is 9A, the charging connection time of charging device C is 9 o’clock, and the charging current is 5A, then the first ramp-up sequence is the charging device A. For charging equipment B and charging equipment C, the first adjustable boost current is 10A-2A+10A-9A+10A-5A=14A, and the first adjustable boost current is greater than the total boost current. The first ramp-up current of the charging device A and the first standard ramp-up current of the charging device B add up to 8A+1A=9A, which is greater than the total ramp-up current 8A, and the accumulated first standard adjustment The rising current is 8A and 1A, the last first quasi-up current is 1A, then the accumulated first quasi-up current except the last first quasi-up current is 8A, which corresponds to the charging of 8A If the device is charging device A, then charging device A is selected as the charging device to be upgraded.

Further, if the total boost current is less than the first quasi boost current of any one of the charging devices in the third charging set, in this case, the charging in any one of the third charging sets Increasing the charging current of the device to the third preset value will cause the real-time power load to exceed the safe current threshold. Therefore, the charging device is not selected from the third charging set as the charging device to be regulated.

Further, when the first adjustable boost current is less than the total boost current and the sum of the first adjustable boost current and the second adjustable boost current is not less than the total boost current, All charging devices in the third charging set are screened as the charging devices to be regulated, and it is obtained that the current regulating target value of the charging devices to be regulated in the third charging set is the third preset value. Set a value, and select some charging devices from the second charging set as the charging devices to be regulated, and obtain the current regulation target value of the charging devices to be regulated in the second charging set. The second preset value. It can be understood that the first adjustable boost current is less than the total boost current, indicating that when the charging currents of all charging devices in the third charging set are increased to the third preset value, there is still Surplus current, so it is necessary to continue to screen part of the charging equipment as the charging equipment to be regulated for charging regulation; further, the sum of the first adjustable boost current and the second adjustable boost current is not less than the total regulation When the current is increased, it means that screening some charging devices from the second charging set to perform charging regulation can meet the needs of charging regulation. Therefore, a second increase sequence is further formed according to the sequence of charging access time, and the Part of the charging devices are selected in the second up-scaling sequence as the charging devices to be regulated.
