The embodiment of the invention provides charging and discharging equipment, a charging and discharging system and a charging and discharging method. The charging and discharging device comprises a resistance conversion circuit, a connection confirmation CC interface and an AC interface. One end of the resistance conversion circuit is grounded, the other end of the resistance conversion circuit is connected with the CC interface, and the CC interface and the AC interface are both used for being connected with an electric automobile. The resistance conversion circuit comprises a plurality of switches and a plurality of resistors, and the plurality of switches are used for adjusting the equivalent resistance value of the resistance conversion circuit. The equivalent resistance value of the resistance conversion circuit is used for the electric vehicle to output the alternating current to the alternating current interface or for the electric vehicle to receive the alternating current output by the alternating current interface, so that the electric vehicle can realize a charging function and a discharging function through the charging and discharging equipment, the charging and discharging operation is simple, and the equipment cost is relatively low.
本申请实施例提供了一种充放电设备、充放电系统和充放电方法。其中,充放电设备包括电阻转换电路、连接确认CC接口和交流接口。电阻转换电路的一端接地,另一端与CC接口连接,且CC接口和交流接口均用于与电动汽车连接。电阻转换电路包括多个开关和多个电阻,多个开关用于调整电阻转换电路的等效电阻值。电阻转换电路的等效电阻值用于电动汽车向交流接口输出交流电,或者用于电动汽车接收交流接口输出的交流电,从而可以使电动汽车通过充放电设备实现充电功能和放电功能,且充放电操作简单,设备成本较低。
