Fig. 1 is an electric vehicle charging apparatus according to an embodiment of the present application. As shown in fig. 1, the apparatus includes: power supply device 100, control device 200, charging device 300, and power distribution device 400.

The power supply device 100 is used for supplying power to the electric vehicle charging equipment.
The control device 200 is configured to obtain vehicle information of a currently-charged vehicle from the power distribution device 400, and select at least one charging module required for charging from the charging device 300 according to the vehicle information, where the vehicle information includes a current charging current of the vehicle.
Of course, the control device 200 may also obtain other information of the charging vehicle from the power distribution device 400 according to the need, for example, the voltage, the state of charge, the temperature, the remaining capacity, and the like of the battery of the charging vehicle.
The charging device 300 includes a plurality of charging modules, and there are charging modules with different rated output currents, and further, the charging device 300 is configured to charge the vehicle according to at least one selected charging module.
The power distribution device 400 is configured to adjust each output of the determined at least one charging module to an output, so as to charge the vehicle through the output.
When the vehicle charging device is used, when a vehicle needs to be charged, the power supply device 100 is firstly connected with the vehicle charging equipment to supply power to the vehicle charging equipment; then, the power distribution device 400 acquires the required current of the vehicle to be charged and sends the required current to the control device 200, the control device 200 calculates the number of each charging module required by the vehicle to be charged according to the required current and sends the distribution result to the charging device 300 and the power distribution device 400, and the control device 200 schedules the power module to be started; the power distribution apparatus 400 adjusts each charging module required by the vehicle to be charged into one output, and connects the one output with the vehicle to be charged, thereby charging the vehicle to be charged.
Further, during the charging process, the control device 200 may calculate the utilization rate of the charging device 300 in real time, and when the utilization rate is low, the control device 200 recalculates the types of the required power modules and the corresponding number thereof according to the current required current of the charging vehicle, so as to improve the utilization rate of the charging device 300.
As can be seen from the above, the charging device 300 in the electric vehicle charging apparatus provided in the embodiment of the present application includes a plurality of charging modules, and different modules can provide different charging currents; the power distribution device 400 is arranged, different charging modules can be selected according to different charging vehicles, and the different charging modules are combined and output through one output end; compared with the prior art that only one fixed charging module can be used for charging the electric vehicle, the charging module can select various modules with different output powers to charge, and thus the high-power module and the low-power module can be combined, waste of the high-power module is reduced, and the utilization rate of the charging equipment is improved.
Optionally, still referring to fig. 1, the charging device 300 includes a high power module 310, a medium power module 320, and a low power module 330.
Further, the high power module 310 may include a first preset number of charging units, the medium power module 320 may include a second preset number of charging units, and the low power module 330 includes a third preset number of charging units.
Further, the rated output power of each charging unit included in each of the high power module 310, the medium power module 320, and the low power module 330 is the same.
Further, the rated output power of each charging unit included in the high power module 310 is greater than the rated output power of each charging unit included in the medium power module 320, and the rated output power of each charging unit included in the medium power module 320 is greater than the rated output power of each charging unit included in the low power module 330.
Further, each charging unit is provided with a charging connection terminal, so that the power distribution apparatus 400 adjusts each output terminal of the determined at least one charging module to one output terminal through the charging connection terminal.
Exemplarily, as shown in fig. 1, the high power module 310 includes four charging units, namely a first charging unit 311, a second charging unit 312, a third charging unit 313 and a fourth charging unit 314, and rated output powers of the four charging units are the same, for example, 40W; the middle power module 320 includes three charging units, namely a fifth charging unit 321, a sixth charging unit 322 and a seventh charging unit 323, and rated output powers of the three charging units are the same, for example, 15W; the low power module 330 includes three charging units, namely an eighth charging unit 331, a ninth charging unit 332 and a tenth charging unit 333, and the rated output powers of the three charging units are the same, such as 2.5W.
Of course, the charging device 300 may also set other power modules according to actual situations, for example, the power modules between the above power levels, which is not limited in this application.
Optionally, the electric vehicle charging apparatus further includes a plug gun, one end of the plug gun is connected to the adjusted output end of the power distribution device 400, and the other end of the plug gun is connected to the charging vehicle, that is, the vehicle charging apparatus and the vehicle are connected through the plug gun, so as to charge the vehicle.
After using the plugging gun, the user only needs to perform the operation of connecting the plugging gun with the vehicle, so that the vehicle is connected with the vehicle charging device, without paying attention to the connection relationship inside the power distribution apparatus 400, and the operation is convenient.
Optionally, the power distribution apparatus 400 is further configured to obtain battery information of the vehicle battery in real time during charging, where the battery information includes a current charging current of the battery.
Of course, the power distribution apparatus 400 may also obtain other information of the charging vehicle according to the requirement, for example, the state of charge, the voltage, the temperature, the remaining capacity, and the like of the battery of the charging vehicle may also be obtained.
The battery information acquired by the power distribution apparatus 400 may be stored in the memory of the power distribution apparatus 400, or may be sent to the control apparatus 200 in time and stored in the memory of the control apparatus 200, so that the battery information can be directly used in data statistics in a later period.
Alternatively, the control device 200 includes a monitoring unit for determining the first module number of the high power modules, the second module number of the medium power modules, and the third module number of the low power modules required for charging the vehicle, based on the vehicle information, such as the charging demand current, and the information of the charging device 300.
The monitoring unit is also used for detecting the utilization rate of the charging modules or the charging units in use in real time, and when the utilization rate is lower than a preset value, determining the number of the first modules in the high-power modules, the number of the second modules in the medium-power modules and the number of the third modules in the low-power modules required by the charging vehicle again.
When determining whether the high-power module needs to be started, the following formula can be used for judging:
I1-N*12>X/I2
wherein I1 is the current demand of charging the charging vehicle at present, I2 is the rated output current of the single module, N is the number of high-power modules, and X is a fixed coefficient.
And when the charging vehicle does not meet the formula, the N +1 high-power modules and the power modules smaller than the high-power modules are determined to be started.
Wherein, X can be confirmed according to actual conditions, for example, when obtaining that the place of charging fills the high-power vehicle more according to long-term statistics, can set up X to the less value to make high-power module be used by big vehicle as far as possible, when filling the low-power vehicle more, thereby improve charging device's utilization ratio, can set up X to the more value, in order to make every power module all utilized as far as possible.
For example, the charge vehicle demand 208A, one unit rated output 150A of the high power module, N208/150 ═ 1, one high power module removed and 58A left, if X15, 150/15 ═ 10A, satisfies the above formula, thus turning on 2 high power modules.
When the vehicle charges, insert the rifle and open, the vehicle can be because of the continuation of charging, and the state of charge can change, and then changes demand voltage and electric current, and battery management module can real-time detection battery state, and the monitoring unit can calculate the module utilization ratio that charges according to the battery state in real time, when great module power utilization ratio is lower, excessively become the miniwatt module with it and charge, releases great power module simultaneously and gives other great vehicles of demand electric current. Or when the high-power module is fully occupied, the power modules of other grades are used for splicing, the principle is from big to small, and the utilization rate of the modules in the system is maximized as much as possible.
Certainly, along with the development of electric vehicles, the battery capacity is increased, the module power can be more diversified, 3 or 4 grades of power modules can exist in one system, and the power modules in different grades meet the charging requirements in different grades, so that the vehicle charging efficiency and the utilization rate of charging equipment are improved.
For example, refer to fig. 2 and fig. 3, where fig. 2 is an electric vehicle charging apparatus implemented in the present application, and fig. 3 is a conventional electric vehicle charging apparatus.
Referring to fig. 2, the charging apparatus 300 of the electric vehicle charging equipment configuration is divided into three types, the first type is a high-power module, the maximum output is 150A, the power is 40kW, and the total number is 4; the second is a middle power module, the maximum output can be 50A, the power can be 15kW, and the total number is 4; the last one is a small power module, which can output 10A at most and 2.5kW of power, and the total number is 8. The total output power of the system is 240 kW.
Referring to fig. 3, the module configuration of the charging device 300 has only one high power module, which can output 150A at the maximum, power 40kW, and 6 in total, and the total power output of the electric vehicle charging apparatus is also 240 kW.
Comparing fig. 2 and 3, the total output power is the same for both electric vehicle charging apparatus schemes, but the kind of configuration module is different.
Further, assuming that there are 10 insertion guns, there is a charging demand for 7 vehicles at present.
In the first scheme, referring to fig. 2, module power is calculated and collocated, and charging of 7 vehicles can be simultaneously satisfied, and the specific allocation scheme is as follows:
the first step is as follows: the No. 1 vehicle needs 160A, a module of 40kW and a module of 2.5kW are distributed at the time, and the highest total current 160A can be output to meet the requirement;
the second step is that: the No. 2 vehicle needs 180A, a module of 40kW and a module of 15kW are distributed at the time, and the highest total current of 200A can be output to meet the requirement;
the third step: the No. 3 vehicle needs 208A, one module of 40kW, one module of 15kW and one module of 2.5kW are distributed at the time, and the highest output can be 210A, so that the requirement is met;
the fourth step: the No. 4 vehicle needs 200A, a 40kW module and a 15kW module are distributed at the time, and the highest output can be 200A, so that the requirement is met;
the fifth step: the number 5 vehicle is in a nearly full state, needs 2A, is distributed with a 2.5kW module at the moment, can output 10A at the highest and meets the requirement;
and a sixth step: the No. 6 vehicle is the same as the No. 5 vehicle;
the seventh step: the No. 7 vehicle is the same as the No. 5 vehicle.
The benefit of this scheme is that after each vehicle is met, 1 15kW and 3 2.5kW modules remain.
Of course, this is only one of the combination modes, and other powers can be used for splicing together to release the high-power module, and the ultimate goal is to maximize the utilization rate of the module.
Second, referring to fig. 3, first, car No. 1 requires 160A, 1 40kW module is not sufficient, and two are allocated. Second, car number 2 requires 180A, 1 module of 40kW is not sufficient, and two are also allocated. Finally, car number 3 requires 208A, two are allocated.
No. 4, No. 5, No. 6 and No. 7 vehicles have no available module and cannot be charged.
Figure BDA0003117570730000101
It is obvious through comparison that the power utilization rate of the module in the scheme 1 reaches 94%, and the charging requirements of more than 7 vehicles can be met simultaneously. And the power utilization rate of the module in the scheme 2 is only 60 percent, the utilization rate is extremely low, the charging requirement of 3 vehicles can be met, and other vehicles cannot be charged.
