The invention provides a charging pile sudden stop self-recovery circuit and method and a charging pile, which relate to the technical field of charging piles. The circuit comprises a control unit and a self-recovery unit. The self-recovery unit comprises a timer and a switch tube; the timer receives asudden stop signal from the sudden stop switch and outputs a level signal to the switch tube, and the switch tube receives the level signal, cuts off the power supply loop within a preset duration and restores the power supply loop after the preset duration; and the control unit receives the sudden stop signal and transmits a control signal to the power supply loop after the power supply loop is recovered. According to the charging pile sudden stop self-recovery circuit, the contactor is controlled to be disconnected rapidly, and the safety problems of fire disasters, electric shock of personnel and the like of the charging pile are avoided. And the charging pile can automatically recover a normal working state. Professionals do not need to go to the site to recover the sudden stop switch, manpower and material resource cost is reduced, operation of the charging station is facilitated, and the use feeling of users is improved.

    本发明提供了充电桩急停自恢复电路、方法以及一种充电桩,涉及充电桩技术领域。所述电路包括:控制单元、自恢复单元;自恢复单元包括:定时器、开关管;定时器接收来自于急停开关的急停信号,向开关管输出电平信号,开关管接收电平信号,在预设时长内,切断供电回路,以及,在预设时长后,恢复供电回路;控制单元接收急停信号,在供电回路恢复后,向供电回路传输控制信号。本发明的充电桩急停自恢复电路,控制接触器断开迅速,避免了充电桩发生火灾、人员触电等安全问题。充电桩可自行恢复正常工作状态。不需要专业人员到现场进行急停开关恢复,降低人力、物力成本的同时,便捷了充电站的运营,提升了用户的使用感。
