The invention, which relates to the technical field of the bidirectional charging pile, discloses an automatic switching system based on grid-connected/off-grid work of a bidirectional charging pile, comprising a first air switch, a second air switch, a third air switch, a fourth air switch, a first AC contactor and a second AC contactor. The input side of the first alternating current contactor is connected with the power supply side of a power grid through the first air switch, the input side of the first alternating current contactor is connected with the side, connected with the power grid, of the two-way charging pile through the second air switch, and the input side of the second alternating current contactor is connected with the inversion side of the two-way charging pile through the third air switch. The output side of the first alternating current contactor and the output side of the second alternating current contactor are connected with the load side of the electric equipment through the fourth air switch. The problem of automatic switching between grid connection and grid disconnection of the bidirectional charging pile can be effectively solved, and damage to the bidirectional charging pile caused by secondary power on after power failure of the power grid is effectively avoided.

    本发明公开了一种基于双向充电桩并/离网工作的自动切换系统,涉及双向充电桩技术领域,包括:第一空开、第二空开、第三空开、第四空开、第一交流接触器和第二交流接触器;所述第一交流接触器的输入侧通过所述第一空开与电网供电侧连接,所述第一交流接触器的输入侧通过所述第二空开与双向充电桩连接电网侧连接,所述第二交流接触器的输入侧通过所述第三空开与双向充电桩逆变侧连接;所述第一交流接触器的输出侧和所述第二交流接触器的输出侧均通过所述第四空开与用电设备负载侧连接。本发明能够有效解决双向充电桩并网与离网的自动切换问题,有效避免电网停电后的二次来电对双向充电桩的损伤。
