Abstract

A charging method includes that after receiving a charging request, a master control device arranges a parking space for an electric vehicle to be charged and sends a traction device a movement instruction generated from the charging request; the traction device drives, according to the movement instruction, a charging controller to move along a guide rail to above the electric vehicle to be charged; the master control device sends a cable transferring instruction to a cable transferring device and the cable transferring device starts to lower a cable; after the cable transferring device lowers the cable to a preset position, the master control device sends a stop instruction to the cable transferring device and the cable transferring device stops lowering the cable; and the cable charges the electric vehicle to be charged.

Dependent claims

A charging method comprising:

using a master control device, after receiving a charging request, to allocate a parking space for an electric vehicle to be charged and send to a traction device a movement instruction generated from the charging request;
using the traction device to drive, according to the movement instruction, a charging controller to move along a guide rail to a place above the electric vehicle to be charged;
using the master control device to send a cable transferring instruction to a cable transferring device and using the cable transferring device to start to lower a cable;
using the master control device, after lowering the cable to a preset position, to send a stop instruction to the cable transferring device to stop lowering the cable by the cable transferring device;
and
using the cable to charge the electric vehicle to be charged;
wherein the using the cable to charge the electric vehicle to be charged comprises:
inserting a charging plug on the cable into a charging socket of the electric vehicle and using the charging controller to detect whether the charging plug is successfully connected to the charging socket of the electric vehicle;
charging the electric vehicle to be charged if it is detected that the connection is successful;
and
using the charging controller to prompt the charging user for a reconnection if it is detected that the connection is not successful;
wherein the using the charging controller to prompt the charging user for the reconnection comprises:
detecting whether the charging user makes the reconnection for a preset time;
using, if no connection is made, the master control device to stop responding to a current charging request and turn to respond to a next charging request;
and
using, if the connection is made, the charging controller to detect whether the charging plug is successfully connected to the charging socket of the electric vehicle;
and
wherein the using, if the connection is made, the charging controller to detect whether the charging plug is successfully connected to the charging socket of the electric vehicle comprises:
determining whether the number of reconnections exceeds the preset number of times;
using, if the number of reconnections exceeds the preset number of times, the master control device to turn to respond to the next charging request;
and
if the number of reconnections does not exceed the preset number of times, using the charging controller to detect whether the charging plug is successfully connected to the charging socket of the electric vehicle.
