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.

Abstract: A method for charging an electric vehicle is provided. The method includes that a mobile charging apparatus transmits its own status information to a centralized battery distribution station; the centralized battery distribution station determines, according to the received status information, whether power of a battery of the mobile charging apparatus is less than a first threshold; if the power of the battery of the mobile charging apparatus is less than the first threshold, the battery of the mobile charging apparatus is processed so that the power of the battery of the mobile charging apparatus is greater than a second threshold, wherein the second threshold is greater than the first threshold; and if the power of the battery of the mobile charging apparatus is not less than the first threshold, the mobile charging apparatus charges the electric vehicle.
