The invention provides a control method of a bidirectional charging pile. The auxiliary power supply in the bidirectional charging pile supplies power to the control system in the bidirectional charging pile when the bidirectional charging pile is powered down, so that the control function of the bidirectional charging pile is normal, and the control method can be executed; when the power supply of the power supply system connected with the bidirectional charging pile is abnormal and the reverse discharging function of the electric vehicle connected to the bidirectional charging pile is started, the reverse charging function of the bidirectional charging pile is started, so that the reverse charging function of the bidirectional charging pile can be started when the power supply of the power supply system connected with the bidirectional charging pile is abnormal. The electric vehicle supplies power to other equipment or loads through the two-way charging pile; besides, the power supply system connected with the two-way charging pile can be a power grid, so that the control method can enable the electric vehicle to supply power to other equipment or loads through the two-way charging pile when the power supply of the power grid is abnormal, namely, the V2H function is realized.
本申请提供一种双向充电桩的控制方法。由于双向充电桩中的辅助电源在双向充电桩掉电时向双向充电桩中的控制系统供电,所以双向充电桩的控制功能正常,即可以执行该控制方法;又由于在与双向充电桩相连的供电系统供电异常且接入双向充电桩的电动汽车已开启反向放电功能时,开启双向充电桩的反向充电功能,所以该控制方法可以在与双向充电桩相连的供电系统供电异常时,使电动汽车通过双向充电桩向其他设备或负载供电;另外,由于与双向充电桩相连的供电系统可以为电网,所以该控制方法可以在电网供电异常时,使电动汽车通过双向充电桩向其他设备或负载供电,即实现V2H功能。
