Abstract:
1. A charging apparatus connected between a utility grid and an electric vehicle, the charging apparatus comprising: a measurement unit connected to the utility grid and configured to measure an output voltage and an output current of the utility grid; a communication unit configured to receive an output voltage information and an output current information of the utility grid, a charging voltage information and a charging current information of the electric vehicle, and a load condition information of the utility grid; a control unit connected to the measurement unit and the communication unit; wherein the control unit configured to control the utility grid to adaptively charge the electric vehicle via a charging connection unit according to the output voltage information, the output current information, the charging voltage information, the charging current information, and the load condition information when the control unit meets a charge authorization condition; wherein the charge authorization condition is a charging permit authorization mode; the electric vehicle judges whether to receive the charging permit command according to the output voltage information and the output current information of the utility grid when the utility grid provides a charging permit command to the electric vehicle via the charging apparatus; wherein the electric vehicle receives the charging permit command when the output voltage and output current of the utility grid meet the required charging voltage and charging current of the electric vehicle.
