The invention provides a split type group control alternating current charging method, aiming at improving the charging utilization rate of an alternating current charging device.
Referring to fig. 1, in an embodiment of the present invention, a split-type group-control ac charging method includes the following steps:
step S100, detecting the capacity of a power distribution device and the number of charging terminals connected to the power distribution device;
step S200, when the number of the charging terminals connected to the power distribution device is multiple and the capacity of the power distribution device is smaller than the total amount of the charging demands of the charging terminals, detecting the time when the charging terminals send out the charging request instructions;
step S300, determining the charging priorities of the plurality of charging terminals according to the time for sending the charging request instruction;
and S400, sequentially charging the plurality of charging terminals according to the sequence of the charging priorities from high to low.
In this embodiment, when the charging terminal needs to charge, the charging terminal sends a corresponding charging request instruction to the power distribution device, and compares the remaining capacity of the power distribution device with the capacity requested by the charging terminal for charging. When the residual capacity of the power distribution device is larger than the capacity requested to be charged by the charging terminal, the power distribution device charges the charging terminal according to the requested charging capacity; when the remaining capacity of the power distribution device is less than or equal to the capacity requested to be charged by the charging terminal, the power distribution device does not charge the charging terminal.
The sum of the capacity of the power distribution device and the capacity for charging each charging terminal is always kept at a constant value, and when the power distribution device finishes charging the charging terminal, the capacity of the power distribution device is restored to the level before the charging terminal is charged, and the capacity of the power distribution device is not reduced after the charging terminal is finished.
In the application scene of electric automobile mass installation, need be equipped with a plurality of charging terminal, simultaneously because every monomer alternating-current charging stake's distribution capacity is great, distribution device can not satisfy all charging terminal's demand, and distribution device hardly satisfies all charging terminal's the demand of charging simultaneously.
When the number of the charging terminals connected to the power distribution device is detected to be multiple, and the capacity of the power distribution device is smaller than the total amount of the charging demands of the charging terminals, the capacity of the power distribution device is not enough to simultaneously meet the charging demands of the charging terminals, at the moment, the power distribution device determines the charging priorities of the charging terminals according to the time of sending the charging requests by the charging terminals, and sequentially charges the charging terminals according to the sequence from high to low of the charging priorities. The earlier the charging terminal sends the charging request, the higher the charging priority of the charging terminal.
Specifically, in the first stage, the capacity of the power distribution device is large enough, that is, the capacity of the power distribution device is larger than the requested electric quantity of the charging terminal, the charging terminal sends the charging request, the power distribution device charges the charging terminal according to the requested electric quantity of the charging terminal, and the earlier the charging request command is sent by the charging terminal in this stage, the earlier the charging request command is sent by the power distribution device to the charging terminal, the higher the charging priority of the charging terminal is.
In the second stage, the capacity of the power distribution device is insufficient, namely the capacity of the power distribution device is less than or equal to the requested electric quantity of the charging terminal, the charging terminal sends a charging request, a part of the capacity of the power distribution device is already distributed to other charging terminals, the residual capacity is less than or equal to the requested electric quantity of the charging terminal, and the power distribution device does not charge the charging terminal. When a charging request sent by the charging terminal is received, recording the time of the charging request sent by the charging terminal for the first time, and sequencing according to the time of the charging request sent by the charging terminal for the first time. When the power distribution device finishes charging other charging terminals, the capacity of the power distribution device is partially increased, the capacity of the power distribution device is larger than the requested electric quantity of the charging terminal, the power distribution device charges the charging terminal which sends the charging request with the earliest time, the earlier the charging terminal sends the charging request instruction at the stage, the earlier the power distribution device charges the charging terminal, and the higher the charging priority of the charging terminal.
For example, the total capacity of the power distribution device is 100 units, and a total of 5 charging terminals are connected. In the first stage, the first charging terminal first requests 30 units of power, the power distribution device satisfies the charging request of the first charging terminal, 70 units remain, the second charging terminal requests 50 units of power, and the electrical device satisfies the charging request of the second charging terminal, 20 units remain. In the second stage, the third charging terminal requests 40 units of electric quantity, the power distribution device has 30 units of electric quantity for satisfying the charging request of the first charging terminal, 50 units of electric quantity for satisfying the charging request of the second charging terminal, the remaining 20 units of electric quantity are not enough for satisfying the 40 units of electric quantity requested by the third charging terminal, and the power distribution device records the charging time requested by the third charging terminal without charging the third charging terminal. After the third charging terminal requests charging, the fourth charging terminal requests 30 units of electric quantity, after the fourth charging terminal requests charging, the fifth charging terminal requests 30 units of electric quantity, and the power distribution device does not charge the fourth or fifth charging terminal, but records the time when the fourth and fifth charging terminals send charging requests. After the power distribution device finishes charging the first charging terminal, the capacity of the power distribution device is recovered to 50 units, the time of sending a charging request instruction by the third charging terminal is earlier than that of the fourth charging terminal and that of the fifth charging terminal, the power distribution device charges the third charging terminal, the capacity of the power distribution device is 20 units, after the second charging terminal is charged, the capacity of the power distribution device is recovered to 70 units, the charging request of the fourth charging terminal and that of the fifth charging terminal can be simultaneously met, and at the moment, the power distribution device sequentially charges the fourth charging terminal and the fifth charging terminal.
The split type group control alternating current charging method comprises the steps of S100, detecting the capacity of a power distribution device and the number of charging terminals connected to the power distribution device; step S200, when the number of the charging terminals connected to the power distribution device is multiple and the capacity of the power distribution device is smaller than the total amount of the charging demands of the charging terminals, detecting the time for the charging terminals to send out charging request instructions; step S300, determining the charging priorities of a plurality of charging terminals according to the time of sending the charging request instruction; and S400, sequentially charging the plurality of charging terminals according to the sequence of the charging priorities from high to low. When the capacity of the charging device is smaller than the capacity requested by the charging terminal, the charging device does not charge the charging terminal, the sum of the capacity of the power distribution device and the capacity for charging each charging terminal is always kept at a constant value, when the power distribution device finishes charging the charging terminal, the capacity of the power distribution device can be restored to the level before charging the charging terminal, and the situation that the capacity of the power distribution device is reduced after the charging terminal finishes charging is avoided. When the charging terminal works, in the first stage, the capacity of the power distribution device is larger than the requested electric quantity of the charging terminal, the charging terminal sends a charging request, and the power distribution device charges the charging terminal according to the requested electric quantity of the charging terminal; in the second stage, a part of capacity in the distribution device is already distributed to other charging terminals, and when the remaining capacity is smaller than or equal to the requested electric quantity of the charging terminals, the time of the charging request sent by the charging terminals for the first time is recorded, and sequencing is performed according to the time of the charging request sent by the charging terminals for the first time. After the power distribution device completes charging of other charging terminals, the capacity of the power distribution device is larger than the requested electric quantity of the charging terminals, the power distribution device charges the charging terminal which sends the earliest charging request time, and the earlier the power distribution device charges the charging terminal, the higher the charging priority of the charging terminal is. By the charging method, the charging utilization rate of the alternating current charging device is improved.
In an embodiment, after the step of detecting the capacity of the power distribution device and the number of the charging terminals connected to the power distribution device in step S100, the split type group control ac charging method further includes the steps of:
when the number of the charging terminals connected to the power distribution device is multiple and the capacity of the power distribution device is smaller than the total amount of the charging demands of the charging terminals, matching the capacity of the power distribution device with the demands of the charging terminals of the power distribution device to obtain a matching result;
and charging the corresponding charging terminal according to the matching result.
In this embodiment, the capacity of the power distribution apparatus is matched with the requirements of the charging terminals according to two principles, the first principle is to satisfy the charging requirements of the charging terminals with the largest number as possible, and the second principle is to maximize the capacity utilization rate of the power distribution apparatus.
According to a first principle, since the total capacity of the distribution device available for charging is constant, the smaller the capacity of the distribution device for a single charging terminal, the greater the number of charging terminals. Therefore, according to the required charge amount of each charging terminal, the power distribution device sequentially charges the plurality of charging terminals in the order from low to high in the required charge amount.
Specifically, the total capacity of the power distribution device is 100 units, and 5 charging terminals are connected in total. The demand of the first charging terminal is 10 units, the demand of the second charging terminal is 25 units, the demand of the third charging terminal is 10 units, the demand of the fourth charging terminal is 35 units, the demand of the fifth charging terminal is 40 units, and the power distribution device charges the first charging terminal, the second charging terminal, the third charging terminal and the fourth charging terminal and simultaneously meets the charging demands of the four charging terminals.
According to a second principle, the total capacity of the distribution device available for charging is constant, the greater the capacity of the distribution device available for charging, the higher the capacity utilization of the distribution device. Therefore, the required charging amount of each charging terminal is combined, and when the required charging amount of the combined charging terminal is less than or equal to the total capacity of the power distribution device and is closest to the total capacity of the power distribution device, the capacity utilization rate of the power distribution device is the highest.
Specifically, the total capacity of the power distribution device is 100 units, and 5 charging terminals are connected in total. The demand amount of the first charge terminal is 20 units, the demand amount of the second charge terminal is 25 units, the demand amount of the third charge terminal is 30 units, the demand amount of the fourth charge terminal is 35 units, and the demand amount of the fifth charge terminal is 40 units. The sum of the demand quantities of the second charging terminal, the fourth charging terminal and the fifth charging terminal is 100 units, and the distribution device charges the second charging terminal, the fourth charging terminal and the fifth charging terminal.
In an embodiment, after the step S100 of detecting the capacity of the power distribution apparatus and the number of the charging terminals connected to the power distribution apparatus, the split type group control ac charging method further includes the steps of:
when the number of the charging terminals connected to the power distribution device is multiple and the capacity of the power distribution device is larger than or equal to the total amount of the charging demands of the charging terminals, the charging terminals are charged respectively.
In this embodiment, when the capacity of the power distribution device is greater than or equal to the total amount of the charging demands of the plurality of charging terminals, the capacity of the power distribution device can satisfy the charging demands of all the charging terminals, and the power distribution device charges the charging terminals according to the charging demands of the charging terminals.
In an embodiment, after the step of detecting the capacity of the power distribution device and the number of the charging terminals connected to the power distribution device in step S100, the split type group control ac charging method further includes the steps of:
setting output power according to the detected number of the charging terminals and the capacity of the power distribution device;
and charging the charging terminal according to the output power.
In this embodiment, when the number of the charging terminals is only one and the capacity of the power distribution device can meet the charging request of the charging terminals, the power distribution device charges according to the maximum power of the charging terminals; when the number of the charging terminals is only one and the capacity of the power distribution device cannot meet the charging request of the charging terminal, the power distribution device uses the remaining capacity for charging the charging terminal.
When the number of the charging terminals is multiple and the capacity of the power distribution device is smaller than the capacity required by all the charging terminals, the output power of the charging terminals is set to reduce the capacity required by all the charging terminals so as to realize that all the charging terminals are in the charging state.
In an embodiment, the step S100 specifically includes the following steps:
and setting a preset detection period, and detecting the number of the charging terminals connected to the power distribution device according to the preset detection period.
In this embodiment, assuming that the preset detection period is T, the number of the charging terminals of the power distribution device is detected every T time, so as to avoid excessive energy consumption caused by detecting the number of the charging terminals all the time.
In an embodiment, before the step of detecting the capacity of the power distribution device and the number of charging terminals connected to the power distribution device in step S100, the split type group control ac charging method further includes the steps of:
detecting the working time of the power distribution device;
setting output power according to the detected working time of the power distribution device;
and charging the charging terminal according to the output power.
In this embodiment, distribution device's operating time overlength can cause the damage, needs in time to change. When the working time of the power distribution device is detected to be longer, the output power of the power distribution device is reduced, and the damage of the power distribution device caused by long-time high-power output is avoided.
