The invention discloses an electric vehicle charging pile with a charging and discharging function, and relates to the technical field of electric vehicle charging piles. A charging and discharging module is installed in the charging pile shell. The charging and discharging module comprises a charging and discharging board and is connected with a discharging switch through an electric wire, the discharging switch is installed on the outer side face of the charging pile shell, and a charging and discharging circuit, K1, K2, K3, R1, R2 and a wiring terminal are welded to the charging and discharging board. The charging and discharging module is connected with a charging and discharging gun head, a dual-power change-over switch and a user distribution box; the charging and discharging module is connected with the charging and discharging gun head through a multi-core cable. The charging pile is connected with the electric vehicle and can discharge outwards, the short-time electricity utilization requirement of a family can be met, through electrical interlocking isolation control, power grid power supply is automatically switched to when power supply of an urban power grid is recovered, the phenomenon of electric energy emptying of the electric vehicle is avoided, and the phenomenon of ignition and short circuit of emergency power supply cannot occur.
本发明公开一种具有充放电功能的电动汽车充电桩,涉及电动汽车充电桩技术领域,包括充电桩外壳;充电桩外壳内安装有充放电模块;充放电模块包括充放电板,且通过电线连接有放电开关,放电开关安装在充电桩外壳的外侧面,充放电板上焊接有充放电电路、K1、K2、K3、R1、R2和接线端子;充放电模块连接有充放电枪头、双电源切换开关和用户配电箱;充放电模块与充放电枪头之间采用多芯线缆连接。本发明充电桩连接电动汽车能够对外放电,能满足家庭短时间的用电需求,通过电气互锁隔离控制,城市电网恢复供电时自动切换至电网供电,避免电动汽车电能放空现象发生,更不会出现与应急供电打火短路现象。
