Specifically, as shown in fig. 2, a two-dimensional code may be disposed on the gate 112 of each charging grid 110 of the charging device, and a user may send the charging request by scanning the two-dimensional code, of course, when the grid gate 112 is not disposed on the charging grid 110, the two-dimensional code may also be disposed at other positions of the charging grid 110, for example, on a sidewall of the charging grid 110, and after the charging device receives the charging request, since the charging request is sent according to the two-dimensional code on the charging grid, it may be determined which charging grid the charging request corresponds to, and open a locking structure of the charging grid corresponding to the charging request, that is, open the grid gate 1. The charging request may also be issued by other manners, for example, the two-dimensional code is not set on the charging grid 110, but a card reader is set, and the user issues the charging request by swiping a card.
And S120, detecting the state of the locking structure, and charging the electric automobile through a charging line connected with a socket in the charging grid after detecting that the locking structure is switched from open to closed.
When the user sends the charging request, after the locking structure of the charging grid corresponding to the charging request is opened, the user can charge one end of the electric automobile on the vehicle to be connected with the electric automobile, one end of the electric automobile is connected with the socket, the locking structure is closed, and when the charging equipment detects that the locking structure generates a process of opening firstly and then closing, the electric automobile can be charged through the charging line connected with the socket of the charging grid.
It can be seen that, in this embodiment, through the above-mentioned method, the user needs to send out the charging request, the battery charging outfit is right open after the charging request is authenticated the grid that charges that the request corresponds, and after the user closes the locking structure once more, battery charging outfit just charges to electric automobile through the vehicle-mounted charging, for the user provides the condition that uses the vehicle-mounted charging normatively, avoided the user because do not fill the electric pile and act as go-between by oneself and charge the condition of charging with the vehicle-mounted charging, both realized that the user conveniently charges to electric automobile through the vehicle-mounted charging, can guarantee again that the vehicle-mounted charging can not receive the damage in the charging process, promoted the security that uses the vehicle-mounted charging to charge.

In this embodiment, the start times corresponding to the charging grids to be charged are determined according to the time sequence that the charging grids to be charged receive the charging requests, that is, the principle of receiving the charging requests first is implemented, for example, the time sequence that the charging requests are received by 4 charging grids A, B, C, D to be charged in the charging system is A, C, B, D, the available capacitance of the charging system is 100, the used capacitance of all charging devices in the charging system is 80, the expected capacitance corresponding to A, B, C, D is 30, then, when the charging of other charging grids in the charging system is completed and the available capacitance is released and is equal to or greater than 30, the charging can be controlled to start A, B, C, D, and according to the expected charging completion times of the rest charging grids, the start time of charging at A, B, C, D can be determined and the start time priority of A, B, C, D should be A, C, B, D, although the start times of the two charge compartments can be set to coincide when the amount of available charge that is released can meet the expected charge capacity of the two charge compartments. And at each starting time, the sum of the estimated capacitances of the used capacitance and the charging grid corresponding to the starting time is not greater than the available capacitance, for example, A, C corresponds to the charging time of X time, namely, the charging grid corresponding to X time is A and C, the estimated capacitances corresponding to A and C are a and b respectively, and the used capacitance at X time is Y, then the sum of Y, a and b must not be greater than the available capacitance.
