Description
Technical Field
The invention relates to a control device, a charging control apparatus, a charging system, a control method, and a storage medium.
Background
There is known a charging system for charging a Vehicle mounted with a battery, such as an EV (Electric Vehicle) or a PHV (Plug-in Hybrid Vehicle). The charging system includes a monitoring device (master) that monitors the amount of electricity used and outputs a charging control instruction corresponding to the amount of electricity used, and a charging control device (slave) that controls the charger based on the charging control instruction output from the monitoring device. The monitoring apparatus manages the electric power so as to avoid exceeding the contract electric power with the power supply carrier (avoid exceeding the required electric power) (for example, refer to japanese patent laid-open No. 2007-318907).
Disclosure of Invention
The monitoring device and the charge control device are connected so as to be able to communicate with each other. In a case where the communication between the monitoring apparatus and the charging control apparatus is interrupted for some reason (a case where the connection is disconnected), the transmission of the charging control instruction from the monitoring apparatus to the charging control apparatus is stopped. In this case, the charging control apparatus controls the charger to stop charging. For example, when the monitoring device and the charge control device are connected by wireless communication, communication may be interrupted in a short time when a large vehicle or the like passes between the monitoring device and the charge control device or when interference of radio waves (noise) occurs. In such a case, if the charging is stopped each time the communication is interrupted, the charging is not performed until the charging is resumed after the charging is stopped, and therefore, the charging efficiency is lowered.
The invention aims to provide a control device, a charging system, a control method and a storage medium, which can improve charging efficiency.
A control device according to the present invention is a control device for controlling a charger based on a charging control instruction transmitted from a monitoring device in a charging system that performs charging based on a power value set based on a usage amount of electricity measured by the monitoring device, the control device including: a receiving unit that receives a charging control instruction; and a control unit that controls the charger based on the charging control instruction received by the receiving unit, wherein when the charging control instruction is not received by the receiving unit, the control unit determines whether to continue charging or stop charging based on the charging control instruction received before a time point when the charging control instruction is not received again.
In the control device according to the present invention, when the charging control instruction is not received by the receiving unit, the control unit determines whether to continue charging or stop charging based on the charging control instruction received before the time point when the charging control instruction is not received any more. Thus, even when communication with the monitoring device is temporarily interrupted, the control device can continue charging in the charger when it is determined that charging can be continued based on a past situation obtained from the charging control instruction received before the time point when the charging control instruction is not received any more. Therefore, the control device can improve the charging efficiency.
The control device may further include a storage unit that stores the power value included in the charging control instruction received by the receiving unit, and the control unit may calculate a predicted value based on a power value within a predetermined period before a time point at which the charging control instruction is not received again, from among the power values stored in the storage unit, and determine whether to continue or stop the charging based on the predicted value. In this configuration, since it is determined whether to continue charging or stop charging based on the estimated value, it is possible to avoid charging beyond the power value even when the charging control instruction from the monitoring device cannot be received. Therefore, the control device can continue charging in the charger while monitoring the electric power.
The control unit may calculate the inclination of the transition of the plurality of power values in a predetermined period and calculate the predicted value based on the inclination of the transition. With this configuration, the predicted value can be calculated with high accuracy.
The storage unit may store the power value each time the charging control instruction is received. In this configuration, the storage unit stores the power value included in all the charging control instructions transmitted from the monitoring device at predetermined communication intervals. Therefore, the control device can calculate the predicted value with high accuracy.
The storage unit may store a current value of the maximum increase in the power value, and the control unit may acquire the current value of the maximum increase associated with a situation at a time point when the receiving unit has not received the charging control instruction any more from the storage unit, and determine whether to continue charging or stop charging based on the predicted value and the current value of the maximum increase. In this configuration, it is determined whether to continue charging or stop charging based on the predicted value and the current value of the maximum increase amount, and therefore it is possible to more reliably avoid charging beyond the electric power value.
The control unit may calculate a time until the reference value of the power value is reached when charging is performed at the current value of the maximum increment with respect to the predicted value from a time point when the charging control instruction is not received again, continue charging from the time point when the charging control instruction is not received again until the time, and stop charging when the time is reached from the time point when the charging control instruction is not received again. In this configuration, charging beyond the power value can be avoided more reliably.
The charge control device according to the present invention includes the control device and a charger controlled by the control device.
The charging control apparatus according to the present invention includes the control device. Thus, the charge control apparatus can achieve an improvement in charging efficiency.
When the charging instruction from the control device is not input, the charger may continue charging until the predetermined target value is reached based on the charging instruction input before the time point when the charging instruction is not input again. In this configuration, even when communication between the control device and the charger is temporarily interrupted, the charger continues charging. Thus, in the charge control apparatus, improvement in charging efficiency can be achieved.
When the charging control instruction is not received by the receiving unit, the charger may not accept a new charging request. In this configuration, charging beyond the power value can be reliably avoided.
The charging system according to the present invention includes: a monitoring device that monitors the amount of electricity used, sets a power value according to the amount of electricity used, and transmits a charging control instruction based on the power value; and the control device.
The charging system according to the present invention includes the control device. Therefore, in the charging system, the charging efficiency can be improved.
A control method according to the present invention is a control method for controlling a charger based on a charging control instruction transmitted from a monitoring device in a charging system that performs charging based on a power value set based on a usage amount of electricity measured by the monitoring device, the control method including: a receiving step of receiving a charging control instruction; and a control step of controlling the charger based on the charging control instruction received in the receiving step, and when the charging control instruction is not received in the receiving step, determining whether to continue charging or stop charging based on the charging control instruction received before a time point at which the charging control instruction is not received any more in the control step.
In the control method according to the present invention, when the charging control instruction is not received in the receiving step, the control step determines whether to continue charging or stop charging based on the charging control instruction received before a time point at which the charging control instruction is not received any more.

Therefore, in the control method, the charging efficiency can be improved.
A storage medium according to the present invention stores a control program for controlling a charger based on a charging control instruction transmitted from a monitoring device in a charging system that performs charging based on a power value set based on a used electric quantity measured by the monitoring device, the control program causing a computer to execute: a receiving step of receiving a charging control instruction; and a control step of controlling the charger based on the charging control instruction received in the receiving step, and when the charging control instruction is not received in the receiving step, determining whether to continue charging or stop charging based on the charging control instruction received before a time point at which the charging control instruction is not received any more in the control step.

Detailed Description
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the description of the drawings, the same or corresponding elements are denoted by the same reference numerals, and redundant description is omitted.
[ first embodiment ]
Fig. 1 is a diagram illustrating a vehicle charging system according to a first embodiment. As shown in fig. 1, a Vehicle charging system 1 is a system that charges a battery (not shown) of a Vehicle V such as an EV (Electric Vehicle) or a PHV (Plug-in Hybrid Vehicle). In the vehicle charging system 1, charging of one or more vehicles V is performed. In the vehicle charging system 1, a plurality of vehicles V can be charged simultaneously. In the vehicle charging system 1, the vehicle V is charged with commercial power P, for example.
The commercial power P supplies alternating current (three-phase 200V). The utility power P is connected to the load L1 via a transformer TA and to the load L2 via a transformer TB. The commercial power P is connected to a charger 24 described later via a transformer TB. The transformers TA and TB are step-down converters that convert electricity received at high voltage into low voltage electricity. The load L1 is, for example, an air conditioner or the like. The load L2 is, for example, lighting. The transformers TA, TB may be three-phase transformers or single-phase transformers. Three-phase power is supplied to the load L1 via a transformer TA as a three-phase transformer. Single-phase power (100V, 200V) is supplied to the load L2 and the charger 24 via a transformer TB that is a single-phase transformer.
The vehicle charging system 1 includes a monitoring device 3 and a charging control device 5. The monitoring device 3 and the charging control device 5 can be arranged at spaced-apart positions. The monitoring device 3 and the charge control device 5 are connected so as to be able to communicate with each other.
< monitoring apparatus >
The monitoring apparatus 3 monitors the amount of power usage (amount of power received) of the commercial power P, and outputs a charge control instruction according to the amount of power usage to the charge control apparatus 5. The monitoring device 3 is provided in, for example, a casing of a high-voltage power receiving device. The monitoring device 3 is supplied with single-phase power as a power source. The monitoring device 3 includes a measuring instrument 10, a current sensor 12, a monitoring control device 14, and a communicator 16. The supervisory control device 14 and the communicator 16 may be different devices or may be one device.
The measuring device 10 measures the amount of commercial power P used. The measuring instrument 10 is connected to the commercial power P. The measuring device 10 includes, for example, a pulse sensor that outputs a pulse signal in accordance with the amount of electricity used by the commercial power P. The pulse sensor outputs a pulse every predetermined power set in advance. The measuring instrument 10 outputs measurement data (pulse data) as a measurement result to the monitoring control device 14.
The current sensor 12 detects a current. The current sensor 12 is, for example, a zero-phase current transformer. The current sensor 12 detects current values of the apparent power supplied to the load L1 and the load L2, respectively. The current sensor 12 outputs a current value as a detection result to the monitoring control device 14.
The supervisory control device 14 is a computer system or processor mounted on an integrated circuit. The monitor and control device 14 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and an input/output interface. Various programs or data are stored in the ROM.
Fig. 2 is a diagram showing a configuration of the monitoring and control device 14. As shown in fig. 2, the monitoring and control device 14 includes a storage unit 140 and a control unit 142.
The storage unit 140 stores various data. The storage unit 140 stores measurement data output from the measuring instrument 10 and a current value output from the current sensor 12. Further, the storage unit 140 stores the reference value. The reference value is a value (power value) set to be smaller by, for example, about 10% than the maximum required value of the required power value described later. The reference value is set as appropriate by a demander (operator).
The reference value is set for the following reason. That is, in the basic charge of the electricity fee, the maximum value (maximum required value) of the required values (maximum value in one month per 30 minutes of average used electric power) in the past year (the current month and the previous eleven months) is applied, so if the required value greater than the required value in the past eleven months is measured at least once in one month, the basic charge of the electricity fee in the following year is decided based on the value. In order to suppress or reduce the electricity charge, it is effective to perform control (demand control) for suppressing the maximum demand value. Therefore, the reference value set at a value not exceeding the maximum required value is used.
The control unit 142 calculates the amount of electricity used by the commercial power P based on the measurement data and the current value stored in the storage unit 140. The control section 142 calculates the amount of electricity used at predetermined time intervals. The predetermined time is, for example, 1 minute. The control unit 142 calculates a power value of the required power of the commercial power P (hereinafter, also referred to as "required power value") based on the used power amount. The control unit 142 stores the required power value in the storage unit 140. The storage unit 140 stores the required power value for every 1 minute.
The control unit 142 generates and outputs a charging control instruction. The charge control instruction includes at least a charging power value (current value) and a required power value in the charger 24 of the charge control apparatus 5. The control unit 142 sets the charging power value based on the amount of used power and the reference value. Specifically, the control unit 142 compares the amount of electricity used with a reference value, and sets a predetermined charging power value to a predetermined value when determining that the amount of electricity used does not exceed the reference value.
When determining that the used electric energy exceeds the reference value, the control unit 142 sets a charging power value (power value with a reduced current value) lower than a predetermined charging power value. Control unit 142 outputs a charging control instruction including the set charging power value to communicator 16. The control section 142 outputs a charging control instruction at intervals of a predetermined time. The predetermined time is, for example, 1 minute.
As shown in fig. 1, the communicator 16 communicates with the charge control apparatus 5. In the present embodiment, the communicator 16 performs wireless communication with a communicator 20 (described later) of the charging control apparatus 5. The communicator 16 is capable of, for example, 920MHz band wireless communication. The communicator 16 transmits the charging control instruction output from the monitoring control device 14 to the charging control apparatus 5.
< charging control apparatus >
The charging control apparatus 5 controls the charger 24 based on the charging control instruction transmitted from the monitoring apparatus 3. The charge control device 5 is provided, for example, in the vicinity of a parking lot or the like where the vehicle V is parked. The single-phase power is supplied to the charge control device 5 as a power supply. The charging control device 5 includes a communicator (receiving unit) 20, a charging control apparatus 22, and a charger 24. The communicator 20 and the charging control device 22 constitute a control device. The communicator 20 and the charge control device 22 may be different devices or may be one device.
The communicator 20 communicates with the monitoring apparatus 3. The communicator 20 wirelessly communicates with the communicator 16 of the monitoring apparatus 3. The communicator 20 is capable of, for example, 920MHz band wireless communication. The communicator 20 transmits and receives information. The communicator 20 receives a charging control instruction from the monitoring device 3 (receiving step). The communicator 20 outputs the received charge control instruction to the charge control device 22.
The charging control device 22 controls the charger 24 based on the charging control instruction output from the communicator 20. The charge control device 22 is a computer system or processor mounted on an integrated circuit. The charge control device 22 is configured by a CPU, ROM, RAM, and the like, and an input/output interface and the like. Various programs or data are stored in the ROM.
Fig. 3 is a diagram showing the configuration of the charge control device 22. As shown in fig. 3, the charge control device 22 includes a storage unit 220 and a control unit 222.
The storage unit 220 stores various data. Storage unit 220 stores the required power value included in the charge control instruction output from communicator 20. The storage unit 220 stores the required power value at predetermined time intervals. The interval of the predetermined time is an interval at which the monitoring device 3 transmits the charging control instruction, and is, for example, 1 minute. That is, storage unit 220 stores the required power value each time the charge control instruction is received. Further, the storage unit 220 stores a current value of the maximum increase amount of the required power value. The maximum increment current value is a current value having the largest increment among the required power values stored on the same date and time in the past. The storage unit 220 stores a reference value set by the monitoring device 3. The reference value is stored in the storage unit 220 at an appropriate timing.
The storage unit 220 stores a control program P1. The control program P1 is a program for operating the charging control device 22, and controls the control unit 222 by operating a computer or the like. The control program P1 causes the computer to execute a receiving step of receiving a charging control instruction and a control step of controlling the charger based on the charging control instruction received in the receiving step. The control program P1 may be provided in a form of being fixedly stored in a tangible storage medium such as a CD-ROM, a DVD-ROM, or a semiconductor memory. Alternatively, the control program P1 may be provided as a data signal superimposed on a carrier wave via a communication network.
When charger 24 is charging and the charging control instruction is not received by communicator 20, control unit 222 determines whether to continue or stop charging based on the charging control instruction received before the time point at which the charging control instruction is no longer received (control step). When the charge control instruction is not input at intervals of a predetermined time (1 minute), that is, when the charge control instruction is not output from the communicator 20 at intervals of a predetermined time, the control unit 222 determines that the charge control instruction is not received at the communicator 20. Control unit 222 sets the time at which it is determined that the charging control instruction is not received in communicator 20 to the time at which the charging control instruction is not received again. The time point when the charge control instruction is not received again may be a time point corresponding to an interval of a predetermined time. Specifically, control unit 222 may set the time at which the charging control instruction was originally received (the time 1 minute after the charging control instruction was received last time) to the time at which the charging control instruction is not received any more.
When determining that the charging control instruction has not been received by the communicator 20, the control unit 222 controls the charger 24 in accordance with a state before the charging control instruction is no longer input. That is, when communication between the monitoring device 3 and the charging control device 5 is interrupted, the control unit 222 controls the charger 24 in accordance with the situation before the interruption of communication.
Specifically, control unit 222 calculates a demand prediction value based on the demanded power value stored in storage unit 220. Control unit 222 acquires the required power value for a predetermined period before the time point at which the charge control instruction is not input again. Specifically, control unit 222 acquires the required power value for a predetermined period including the required power value before the time point at which the charging control instruction is not input any more. The predetermined period is, for example, 30 minutes. The control unit 222 calculates a demand prediction value based on the gradient of the transition of the acquired demand power value. Specifically, the control unit 222 obtains the slope from the change in the required power value (30-point group) in the past 30 minutes. The control unit 222 obtains a prediction line passing through the nearest point of the required power value based on the slope, and calculates a predicted required value from the relationship between the prediction line and the required curve.
The control unit 222 predicts the time exceeding the reference value stored in the storage unit 220 based on the calculated demand prediction value and the maximum increase current value stored in the storage unit 220. Specifically, the control unit 222 adds the current value of the maximum increment to the demand prediction value to calculate the time exceeding the reference value. That is, the control unit 222 calculates how many hours (minutes) the maximum increase current value is supplied in addition to the demand prediction value, and then exceeds the reference value.
The control unit 222 acquires data on the current value of the maximum increase amount (hereinafter, also referred to as "increase data") from the storage unit 220. Control section 222 acquires from storage section 220 a current value of the maximum increase amount associated with the situation at the time point at which the charging control instruction is no longer received in communicator 20. The maximum increase amount of current value associated with the situation may be the maximum increase amount of current value for the same time of month as the time point at which the charge control instruction is not received any more, the same time of day as the time point, the season at the time point, and the like. In the present embodiment, the control unit 222 acquires the added data based on a priority set in advance. The control section 222 acquires the increasing data in the order of priority from high to low. The priority is set, for example, as follows. The priority level becomes lower in the order of "1", "2", "3", and "4". The priority is appropriately set by an operator or the like.
1: the data increase in the same month and the same time of the last year
2: data increase on same day of week and same moment in last year
3: increased data of the previous day and the same time
4: past 30 minute incremental data
When the time point when the charge control instruction is not input again is "YYYY year MM month DD day", "tuesday", and "AA time BB point", the control unit 222 searches the memory unit 220 for the added data of the same month (MM month) and the same time (AA time BB point) of the previous year. When the storage unit 220 stores the addition data of the same month and the same time of the previous year, the control unit 222 acquires the addition data.
If the storage unit 220 does not store the same month and same time of the previous year as the added data, the control unit 222 searches the storage unit 220 for the added data of the same day (tuesday) and the same time (AA-time BB point). When the storage unit 220 stores the addition data of the same day and the same time, the control unit 222 acquires the addition data.
If the storage unit 220 does not store the same day and same time of day increment data, the control unit 222 searches the storage unit 220 for the increment data of the previous day and the same time (AA and BB). When the storage unit 220 stores the addition data of the same time of the previous day, the control unit 222 acquires the addition data.
When the data of the maximum increase amount at the same time on the previous day is not stored in storage unit 220, control unit 222 acquires the increase data of the past 30 minutes at the time point when the charging control instruction is not input again from storage unit 220. The control unit 222 stores the incremental data acquired as described above in the storage unit 220 as data used in the current processing.
The control unit 222 calculates an excess time exceeding the reference value based on the acquired increase data and the demand prediction value. Control unit 222 determines whether to continue charging or stop charging based on the elapsed time. If the time is within the excess time, control unit 222 determines that charging is to be continued. In this case, control unit 222 generates a charging instruction and outputs the instruction to charger 24 to charge charger 24. If the time has elapsed, control unit 222 determines to stop charging. In this case, control unit 222 stops outputting the charging instruction to charger 24. Thereby, the charging in the charger 24 is ended.
The operation (control method) of the charge control device 5 will be described with reference to fig. 4. Fig. 4 is a flowchart showing the operation of the charge control device 5. The following describes an operation performed when the charge control instruction is not received again by the charge control device 5.
As shown in fig. 4, the charging control apparatus 5 determines whether or not a charging control instruction is received (step S01). When determining that the charging control instruction has been received (yes in step S01), the charging control apparatus 5 ends the process. If it is determined that the charging instruction has not been received (no in step S01), the charging control apparatus 5 proceeds to step S02.
In step S02, the charge control apparatus 5 calculates a demand prediction value. Next, the charge control device 5 acquires the added data (step S03). Next, the charge control device 5 adds the current value of the maximum increase amount to the demand prediction value, and calculates an excess time exceeding the reference value (step S04). The charging control device 5 generates a charging instruction and outputs the charging instruction to the charger 24 so that the charger 24 performs charging within the calculated excess time (step S05).
Next, the charge control device 5 determines whether the excess time has reached (step S06). When determining that the elapsed time has elapsed (yes in step S06), the charge control device 5 stops outputting the charge instruction (step S07). If it is determined that the elapsed time has not been reached (no in step S06), the charging control apparatus 5 returns to the process in step S05.
As shown in fig. 1, one or more chargers 24 are provided in the charge control apparatus 5. The charger 24 charges the battery of the vehicle V. The charger 24 is supplied with single-phase 200V power from the commercial power P via a transformer TB. The charger 24 and the charge control device 22 are connected so as to be able to communicate with each other. Charger 24 controls the charging current based on the charging instruction (current value) output from charge control device 22, and charges the battery of vehicle V. The charger 24 and the vehicle V are connected by a charging cable C.
When the charging instruction from charging control device 22 is not input during the charging process, charger 24 performs charging control based on the current value of the immediately preceding charging instruction. That is, in the case where the communication between the charging control apparatus 5 and the charger 24 is interrupted, the charger 24 performs charging based on the charging instruction immediately before the communication interruption. Specifically, for example, when receiving a charging instruction based on the current value of "30A", charger 24 continues charging at "30A". The charger 24 performs charging based on the current charge amount and the target value. When the charge amount reaches the target value, charger 24 ends the charging.
In the case where the charging control instruction is not received in the communicator 20, the charger 24 does not accept the charging request in the case where there is a new charging request. That is, in a state where the charge control instruction is not received in the charge control apparatus 5, the charger 24 does not accept an instruction of a new charge start.
The operation of the charger 24 will be described with reference to fig. 5. Fig. 5 is a flowchart showing the operation of charger 24. The following describes an operation in a case where the charger 24 does not receive any more charging instruction.
As shown in fig. 5, the charger 24 determines whether or not a charging instruction is received (step S11). When determining that the charge control instruction has been received (yes in step S11), the charge control device 5 ends the process. When determining that the charging instruction has not been received (no in step S11), the charging control apparatus 5 proceeds to step S12.
In step S12, the charger 24 performs charging based on a charging instruction (current value) immediately before the communication interruption. The charger 24 determines whether the charge amount has reached the target value (step S13). When determining that the amount of charge has reached the target value (yes in step S13), charger 24 stops charging (step S14). When determining that the amount of charge has not reached the target value (no in step S13), charger 24 returns to the process of step S12.
As described above, in the vehicle charging system 1 according to the present embodiment, when the charging control instruction is not received by the communicator 20, the control unit 222 of the charging control device 22 determines whether to continue charging or stop charging based on the charging control instruction received before the time point when the charging control instruction is not received again. Thus, even when communication with the monitoring device 3 is temporarily interrupted, the charging control device 22 can continue charging in the charger 24 when it is determined that charging can be continued based on the past situation obtained from the charging control instruction received before the time when the charging control instruction is no longer received. Therefore, in the vehicle charging system 1, the charging efficiency can be improved.
In the vehicle charging system 1 according to the present embodiment, the required power value is included in the charging control instruction transmitted from the monitoring device 3. The charging control device 22 includes a storage unit 220, and the storage unit 220 stores the required power value included in the charging control instruction received by the communicator 20. The control unit 222 calculates a demand prediction value based on the demand power value stored in the storage unit 220 for a predetermined period before the time point when the charging control instruction is no longer received, and determines whether to continue or stop charging based on the demand prediction value. In this configuration, since it is determined whether to continue charging or stop charging based on the demand prediction value, even when the charging control instruction from the monitoring device 3 cannot be received, it is possible to avoid the charging exceeding the demand power value. Therefore, the charging control device 22 can continue charging in the charger 24 while performing demand monitoring.
In the vehicle charging system 1 according to the present embodiment, the control unit 222 obtains the slopes of the transition of a plurality of required power values within a predetermined period, and calculates the predicted required value based on the slopes of the transition. In this configuration, the demand prediction value can be calculated with high accuracy.
In the vehicle charging system 1 according to the present embodiment, the storage unit 220 stores the required power value each time the charging control instruction is received. In this configuration, storage unit 220 stores the required power value included in all the charging control instructions transmitted from monitoring device 3 at predetermined communication intervals. Therefore, the charge control device 22 can calculate the demand prediction value with high accuracy.
In vehicle charging system 1 according to the present embodiment, storage unit 220 stores a current value of the maximum increase in the required power value. The control section 222 acquires, from the storage section 220, the current value of the maximum increase amount associated with the situation at the time point at which the charging control instruction is no longer received in the communicator 20, and determines whether to continue charging or to stop charging based on the demand predicted value and the current value of the maximum increase amount. In this configuration, it is determined whether to continue charging or stop charging based on the demand prediction value and the current value of the maximum increase amount, and therefore it is possible to more reliably avoid charging beyond the demand power value.
For example, when the time point at which the charging control instruction is no longer received in the communicator 20 (when the communication between the monitoring device 3 and the charging control device 5 is interrupted) is midday in summer (for example, 8 months), since the air conditioner such as an air conditioner is being used, the current value of the maximum increase amount is larger than that in spring or the like. Therefore, by acquiring the current value of the maximum increase amount associated with the situation at the time point at which the charging control instruction is not received again in the communicator 20 from the storage unit 220 and determining whether to continue charging or stop charging based on the demand predicted value and the current value of the maximum increase amount, it is possible to make a determination appropriate to the time point at which the charging control instruction is not received again.
In the vehicle charging system 1 according to the present embodiment, the control unit 222 calculates the excess time to reach the reference value relating to the required power when the vehicle is charged at the current value of the maximum increase amount with respect to the required predicted value from the time point when the charging control instruction is no longer received. Control unit 222 continues charging until the excess time is reached from the time point when the charging control instruction is not received again, and control unit 222 stops charging when the excess time is reached from the time point when the charging control instruction is not received again. In this configuration, charging beyond the required power value can be avoided more reliably.
In vehicle charging system 1 according to the present embodiment, when a charging instruction is not input from charge control device 22, charger 24 continues charging until a predetermined target value is reached based on the charging instruction input before the time point at which the charging instruction is not input again. In this configuration, charger 24 continues charging even when communication between charge control device 22 and charger 24 is temporarily interrupted. Therefore, in the vehicle charging system 1, the charging efficiency can be improved.
In the vehicle charging system 1 according to the present embodiment, when the charging control instruction is not received by the communicator 20, the charger 24 does not receive a new charging request. In this configuration, charging beyond the required power value can be reliably avoided.
[ second embodiment ]
Next, a second embodiment will be explained. Fig. 6 is a diagram illustrating a vehicle charging system according to a second embodiment. As shown in fig. 6, the vehicle charging system 1A includes a monitoring device 3, a charging device 7, and a server (control device) 9.
The monitoring device 3 and the server 9, and the charging device 7 and the server 9 are connected via a network N so as to be able to communicate with each other. The configuration of the network N is not limited. For example, the network N may be configured to include the internet (public network), a communication carrier network, a carrier network, and the like.
< monitoring apparatus >
The communicator 16 of the monitoring device 3 communicates with the server 9. The communicator 16 communicates with the server 9 via the network N. The communicator 16 transmits a charging control instruction to the server 9.
< charging apparatus >
The charging device 7 performs charging based on the charging instruction transmitted from the server 9. The charging device 7 is provided, for example, in the vicinity of a parking lot or the like where the vehicle V is parked. The single-phase power is supplied to the charging device 7 as a power source. The charging device 7 is provided with a communicator 30 and a charger 32.
The communicator 30 communicates with the server 9. The communicator 30 communicates with the server 9 via the network N. The communicator 30 receives a charging instruction from the server 9. Communicator 30 outputs the received charging instruction to charger 32.
One or more chargers 32 are provided. Charger 32 charges the battery of vehicle V. Charger 32 is supplied with single-phase 200V power from commercial power P via transformer TB. Charger 32 controls the charging current based on the charging instruction (current value) output from communicator 30, and charges the battery of vehicle V. The charger 24 and the vehicle V are connected by a charging cable C.
When the charging instruction from communicator 30 is not input during the charging process, charger 32 performs charging control based on the current value of the immediately preceding charging instruction. That is, when communication between charging apparatus 7 and server 9 is interrupted or when communication between communicator 30 and charger 32 is interrupted, charger 32 performs charging based on a charging instruction immediately before the interruption of communication. Specifically, for example, when receiving a charge instruction based on the current value of "30A", charger 32 continues the charging at "30A". Charger 32 performs charging based on the current charge amount and the target value. When the charge amount reaches the target value, charger 32 ends the charging.
If the communication unit 90 of the server 9 does not receive the charge control instruction, the charger 32 does not accept the charge request if there is a new charge request. That is, in a state where the charging control instruction is not received in server 9, charger 32 does not accept a new instruction to start charging.
< Server >
The server 9 may be configured by one or more devices provided on the cloud, for example. The server 9 generates a charging instruction based on the charging control instruction transmitted from the monitoring device 3. The server 9 is a computer system or processor mounted on an integrated circuit. The server 9 is composed of a CPU, ROM, RAM, and the like, and an input/output interface and the like. Various programs or data are stored in the ROM.
Fig. 7 is a diagram showing the configuration of the server 9. As shown in fig. 7, the server 9 includes a communication unit 90, a storage unit 92, and a control unit 94.
The communication unit 90 communicates with the monitoring device 3 and the charging device 7. The communication unit 90 transmits and receives information to and from each of the monitoring device 3 and the charging device 7 via the network N. The communication unit 90 receives a charging control instruction from the monitoring device 3 (receiving step). Communication unit 90 outputs the received charge control instruction to storage unit 92 and control unit 94. The communication unit 90 transmits a charging instruction to the charging device 7.
The storage unit 92 stores various data. Storage unit 92 stores the required power value included in the charge control instruction output from communication unit 90. The required power value is stored at intervals of a predetermined time. The interval of the predetermined time is an interval at which the monitoring device 3 transmits the charging control instruction, and is, for example, 1 minute. Further, the storage unit 92 stores a current value of the maximum increase amount of the required power value. The maximum increment current value is a current value having the largest increment among the required power values stored on the same date and time in the past. The storage unit 220 stores the reference value. The reference value is stored in the storage unit 220 at an appropriate timing.
The storage unit 92 stores a control program P2. The control program P2 is a program for operating the server 9, and controls the control unit 94 by operating a computer or the like. The control program P2 causes the computer to execute a receiving step of receiving the charging control instruction and a control step of controlling the charger based on the charging control instruction received in the receiving step.
When charger 32 is charging and the charging control instruction is not received at communication unit 90, control unit 94 determines whether to continue charging or stop charging based on the charging control instruction received before the time point at which the charging control instruction is not received any more (control step). When the charge control instruction is not input, that is, when the charge control instruction is not output from communication unit 90, control unit 94 controls charger 32 in accordance with a state before the charge control instruction is no longer input. That is, when communication between monitoring apparatus 3 and server 9 is interrupted, control unit 94 controls charger 32 in accordance with the situation before the interruption of communication.
The control unit 94 calculates the excess time exceeding the reference value based on the increase data and the demand prediction value acquired by the same method as the above-described method. The control unit 94 determines whether to continue or stop charging based on the elapsed time. The control unit 94 determines that charging is continued for the excess time. In this case, control unit 94 generates a charging instruction and transmits the charging instruction to charging device 7 to charge charger 32. If the time has elapsed, control unit 94 determines to stop charging. In this case, the control unit 94 stops transmitting the charging instruction to the charging device 7. Thereby, charging in charger 32 ends.
As described above, the vehicle charging system 1A according to the present embodiment provides the same operational advantages as the vehicle charging system 1. That is, in vehicle charging system 1A, when the charging control instruction is not received in communication unit 90, control unit 94 of server 9 determines whether to continue charging or stop charging based on the charging control instruction received before the time point when the charging control instruction is not received again. Thus, in the vehicle charging system 1A, even when communication between the monitoring device 3 and the server 9 is temporarily interrupted, if it is determined that charging can be continued based on a past situation obtained from a charging control instruction received before a point in time when the charging control instruction is not received any more, charging can be continued in the charger 32. Therefore, in the vehicle charging system 1A, the charging efficiency can be improved.
[ third embodiment ]
Next, a third embodiment will be explained. Fig. 8 is a diagram illustrating a vehicle charging system according to a third embodiment. As shown in fig. 8, in the vehicle charging system 1B, the vehicle V is charged with commercial power P. The commercial power P supplies alternating current (three-phase 200V). A charger 24 is connected to the commercial power P via a transformer T as a single-phase transformer.
The vehicle charging system 1B includes a monitoring device 3B and a charging control device 5B. The monitoring device 3B and the charging control device 5B can be disposed at positions separated by a distance. The monitoring device 3B and the charging control device 5B are connected so as to be able to communicate with each other.
< monitoring apparatus >
The monitoring device 3B monitors the amount of electricity used by the commercial power P, and outputs a charge control instruction corresponding to the amount of electricity used to the charge control device 5. The monitoring device 3B includes a measuring instrument 10, a current sensor 12, a monitoring control device 14B, a communicator 16, and a breaker 18. The supervisory control device 14 and the communicator 16 may be different devices or may be one device.
The current sensor 12 detects a current. The current sensor 12 is, for example, a zero-phase current transformer. The current sensor 12 detects a current value of apparent power supplied to the charger 24. The current sensor 12 outputs a current value as a detection result to the monitoring control device 14.
Fig. 9 is a diagram showing the configuration of the monitoring control device 14B. As shown in fig. 9, the monitoring and control device 14B includes a storage unit 140B and a control unit 142B.
The storage unit 140B stores various data. The storage unit 140 stores measurement data output from the measuring instrument 10 and a current value output from the current sensor 12. Further, storage unit 140B stores a capacity value related to the capacity (rated breaking capacity) of breaker 18. The capacity value is stored at an appropriate timing.
The control unit 142B calculates the amount of used electricity based on the measurement data and the current value stored in the storage unit 140B. The control portion 142B calculates the amount of electricity used at predetermined time intervals. The control unit 142B generates and outputs a charge control instruction based on the used electric quantity and the capacity value. The charging control instruction includes at least a charging power value (current value) in the charger 24 of the charging control apparatus 5B. The control unit 142B sets the charging power value based on the used electric energy and the capacity value. Specifically, the control unit 142B compares the amount of electricity used with the capacity value, and sets a predetermined charging power value set in advance when determining that the amount of electricity used does not exceed the capacity value.
When determining that the used electric energy exceeds the capacity value, the control unit 142B sets a charging power value (power value with a reduced current value) lower than a predetermined charging power value. Control unit 142B outputs a charging control instruction including the set charging power value to communicator 16. The control section 142B outputs a charging control instruction at intervals of a predetermined time. The predetermined time is, for example, 1 minute.
As shown in fig. 8, when the used electricity amount exceeds the rated cutoff capacity, the breaker 18 cuts off the supply of electric power from the commercial power P to the charger 24.
< charging control apparatus >
The charging control apparatus 5B controls the charger 24 based on the charging control instruction transmitted from the monitoring apparatus 3B. The charging control apparatus 5B includes a communicator (communication unit) 20, a charging control device 22B, and a charger 24. The communicator 20 and the charging control device 22B constitute a control device. The communicator 20 and the charging control device 22B may be different devices or may be one device.
The storage unit 220B stores various data. The storage unit 220 stores the capacity value of the breaker 18. The capacity value is stored in the storage unit 220B at an appropriate timing.
The storage unit 220B stores a control program P3. Control program P3 is a program for operating charging control device 22B, and causes a computer or the like to operate to execute control of control unit 222B. The control program P3 causes the computer to execute a receiving step of receiving the charging control instruction and a control step of controlling the charger based on the charging control instruction received in the receiving step.
When charger 24 is charging and the charging control instruction is not received by communicator 20, control unit 222B determines whether to continue charging or stop charging based on the information on the capacity of breaker 18. Specifically, control unit 222B determines whether to continue charging or stop charging based on the capacity value stored in storage unit 220B. The control unit 222B performs charging control based on the power value of the charging control instruction before the charging control instruction is no longer received in the communicator 20, and determines that charging is to be continued when the amount of electricity does not exceed the capacity value. In this case, control unit 222B generates a charging instruction and outputs the instruction to charger 24 to charge charger 24. The control unit 222B performs charging control based on the power value of the charging control instruction before the charging control instruction is no longer received by the communicator 20, and determines that charging is to be stopped when the electric energy exceeds the capacity value. In this case, control unit 222B stops outputting the charging instruction to charger 24. Thereby, the charging in the charger 24 is ended.
One or more chargers 24 are provided in the charge control device 5B. The charger 24 charges the battery of the vehicle V. The charger 24 is supplied with single-phase 200V power from the commercial power P via the transformer T. Charger 24 and charge control device 22B are connected so as to be able to communicate with each other. Charger 24 controls the charging current based on the charging instruction (current value) output from charge control device 22B, and charges the battery of vehicle V. The charger 24 and the vehicle V are connected by a charging cable C.
When the charging instruction from charging control device 22B is not input during the charging process, charger 24 performs charging control based on the current value of the immediately preceding charging instruction. That is, the charger 24 performs charging based on a charging instruction before the communication interruption in the case where the communication between the charging control apparatus 5B and the charger 24 is interrupted. Specifically, for example, when receiving a charging instruction based on the current value of "30A", charger 24 continues charging at "30A". The charger 24 performs charging based on the current charge amount and the target value. When the charged amount reaches the target value, charger 24 ends the charging.
When the communication device 20 is in a state where the charge control instruction is not received, the charger 24 does not accept the charge request when there is a new charge request. That is, in a state where the charge control instruction is not received in the charge control apparatus 5B, the charger 24 does not accept an instruction of a new charge start.
As described above, in the vehicle charging system 1B according to the present embodiment, when the charging control instruction is not received by the communicator 20, the control unit 222B of the charging control device 22B determines whether to continue charging or stop charging based on the information on the capacity of the breaker 18. Thus, in the vehicle charging system 1B, even when communication between the monitoring device 3B and the charging control device 5B is temporarily interrupted, if it is determined based on the information on the capacity of the breaker 18 that charging can be continued within the range of the capacity, charging can be continued in the charger 24. Therefore, in the vehicle charging system 1B, the charging efficiency can be improved.
While the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various modifications can be made without departing from the scope of the invention.
In the above embodiment, a description has been given of an example of a mode in which the measuring instrument 10 measures the amount of power used by the commercial power P. However, the power usage may be acquired based on the received power information of the smart meter.
In the above embodiment, the description has been given taking as an example a mode in which the communicator 16 of the monitoring device 3, 3B wirelessly communicates with the communicator 20 of the charge control device 5, 5B. However, communicator 16 and communicator 20 may also be in wired communication.
In the above embodiment, a description has been given of an example of a mode in which the charging control device 22 collectively controls the plurality of chargers 24 in the vehicle charging system 1. However, a plurality of charging control devices may be provided, and the charging device 24 may be controlled by each charging control device.
In addition to the above embodiment, the monitoring control device 14 of the monitoring device 3B of the vehicle charging system 1A may be provided in a server on the cloud.
