When the lock is unlocked, the storage battery car is charged with constant current and then constant voltage, the current is reduced along with the increase of power during later charging, when the current is reduced to the jump current of turning a red light to a green light (full), the single chip microcomputer judges that the storage battery car is fully charged, a switch originally connected into a small led lamp circuit jumps to a circuit for controlling the bidirectional electric push rod 10, and the small led lamp stops working;

the bidirectional electric push rod 10 acts 0.2cm towards two ends respectively, at the moment, the opening part 1002 of the electric push rod 10 is inserted into the middle of the locking piece 9 and the bolt shell 8, so that the distance between the locking piece 9 and the bolt shell is increased, the locking groove 907 is higher than the top of the locking piece 7, the locking piece 7 (and the whole bolt 3) loses the limiting effect of the locking groove 907 and moves upwards under the elastic force of the first spring 12, the bolt 3 which is extended out of the box body 1 is driven to be retracted into the box body, the box body lock shell can be opened, the electric push rod 10 resets after completing the action, and the circuit switch is disconnected;

the storage battery car charges unfinished, but the charging time is not enough, perhaps the user passes through the customer end and stops charging, and cloud system can send to the control system who fills electric pile and stop output (electric current) signal during the outage, does not have the electric current in the point circuit of charging, and the singlechip judges to stop charging, and the switch that originally inserts led small lamp circuit jumps to the circuit of the two-way electric putter of control, and the electric putter effect is as above-mentioned automatic action of unblanking of accomplishing.

The provision of the plunger portion 1001 is to ensure that the end of the power push rod is between the locking element and the latch housing.

When the current in the charging circuit is jumping current or no current, the singlechip controls the switch originally connected to the led circuit to jump to the electric push rod circuit, and the subsequent automatic unlocking action is completed.

The utility model discloses only increase the improvement of small-size spare part on original electric pile that fills, do not have too big change to the whole manufacturing cost who fills electric pile, prevent pulling out and set up reliably, it is little that the electric pile outward appearance whole changes, and the space occupies for a short time, and box size and other parts can be according to filling the electric pile size and carrying out the adaptability adjustment, and the application is wide, easily uses widely.

It will be understood by those skilled in the art that all or part of the steps in the method for implementing the above embodiments may be implemented by relevant hardware instructed by a program, and the program may be stored in a computer-readable storage medium, such as ROM/RAM, magnetic disk, optical disk, etc.
