Specifically, as the selectable priority increases, the maximum charge value of the preset charge range corresponding thereto decreases.
That is, the lower the remaining charge in the charging pile, the higher the priority of energy supply determined for it, so that it is more timely to distribute energy supply.
Under the condition that the energy supply priority of a plurality of electric pile of filling is the same, according to a plurality of energy supply priorities from high to low order, select a plurality of electric piles of filling as a plurality of target electric piles, include: determining the residual output power of a power grid and the AC-DC maximum conversion power of each charging pile; under the condition that the sum of the AC-DC maximum conversion power of a plurality of charging piles with the same energy supply priority is smaller than or equal to the residual output power of the power grid, determining that the plurality of charging piles with the same energy supply priority are all target charging piles; and under the condition that the sum of the AC-DC maximum conversion power of the plurality of charging piles with the same energy supply priority is larger than the residual output power of the power grid, determining part of the plurality of charging piles with the same energy supply priority as target charging piles.
By adopting the above arrangement, under the condition that the energy supply priorities of the charging piles are the same, in order to more effectively determine which part of the charging piles are supplied with energy, the energy is distributed according to the residual output power of the power grid, specifically, under the condition that the sum of the AC-DC maximum conversion powers of the charging piles with the same energy supply priorities is less than or equal to the residual output power of the power grid, the residual output power of the power grid is sufficient, at this moment, all the charging piles under the priorities can be determined as target charging piles, and the charging piles are charged at the same time. Under the condition that the sum of the AC-DC maximum conversion power of the plurality of charging piles with the same energy supply priority is larger than the residual output power of the power grid, the residual output power of the power grid is insufficient, at the moment, part of the charging piles are selected from the plurality of charging piles under the priority to serve as target charging piles, the power grid overload can be avoided, and the safety of the charging piles during energy supplement is ensured.
Specifically, control carries out the energy supply to a plurality of target charging stake, includes: determining the current allowable power of each target charging pile; controlling the energy supply of each target charging pile with corresponding current allowable power; wherein, confirm the current power of allowwing of each target stake of charging, include: if the vehicle-end required power of a certain target charging pile is smaller than or equal to the DC-DC maximum conversion power of the target charging pile, taking the smaller of the allowable battery pack charging power of the target charging pile and the AC-DC maximum conversion power of the target charging pile as the current allowable power; and if the vehicle-end required power of a certain target charging pile is greater than the DC-DC maximum conversion power of the target charging pile, taking the smaller of the vehicle-end required power of the target charging pile and the AC-DC maximum conversion power of the target charging pile as the current allowable power.

When the vehicle end required power of the target charging pile is larger than the DC-DC maximum conversion power of the target charging pile, the fact that the output power of the DC-DC module of the target charging pile cannot meet the power requirement of the vehicle end is indicated, AC-DC cross-over connection needs to be carried out, at the moment, the smaller of the vehicle end required power of the target charging pile and the AC-DC maximum conversion power of the target charging pile is used as the current allowable power, the vehicle end requirement can be met through energy compensation, and the reliability of vehicle end charging is guaranteed.
In order to conveniently obtain the residual output power of the power grid and the AC-DC maximum conversion power of each charging pile, the method for determining the residual output power of the power grid and the AC-DC maximum conversion power of each charging pile comprises the following steps: calculating the difference value between the rated output power of the power grid and the real-time output power of the power grid to obtain the residual output power of the power grid; and determining the AC-DC maximum conversion power of each charging pile according to the real-time temperature of the AC-DC conversion module of each charging pile.

Specifically, when the sum of the AC-DC maximum conversion power of a plurality of charging piles with the same energy supply priority is greater than the remaining output power of the power grid, determining that a part of the plurality of charging piles with the same energy supply priority is a target charging pile includes: if the energy supply priorities of the charging piles with the same energy supply priority are the preset priorities, the charging piles are selected as the target charging piles according to the sequence from front to back when the charging piles are started.
That is to say, when the vehicle end required power of a plurality of charging piles is greater than the maximum DC-DC conversion power, it indicates that the charging piles have AC-DC cross-over connection requirements, at this moment, the charging piles are all configured to a preset priority level, if the residual output power of the power grid cannot meet the energy supply requirements of all the charging piles under the preset priority level, the target charging piles are determined according to the sequence from the front to the back at the moment that each charging pile starts to charge, it is ensured that the charging pile which charges first obtains energy supply earlier, therefore, the charging of a corresponding vehicle is finished as soon as possible, and the situation that the charging time of a part of vehicles is too long is avoided.
