The embodiment of the invention provides a charging system, a method and a device thereof, electronic equipment and a storage medium, and the charging system comprises a battery module, an inversion module, a three-phase motor, a charging module, a rectification module, a charging interface and a first switch. The inversion module is connected in parallel between the first end of the battery module and the second end of the battery module; the inversion module is connected with the three-phase motor and is used for controlling the working state of the three-phase motor; the charging module is connected with a neutral point of the three-phase motor through the first switch; the first end of the charging module is also connected with the main positive common end of the inversion module; the charging interface is connected with the charging module through the rectification module. By means of the first switch, functions of charging and motor inversion can be multiplexed, the advantage of electrical integration is fully played, a secondary full-bridge power device of the charging module is omitted, functions of the motor inversion module are multiplexed, use of power devices is greatly reduced, and cost is effectively reduced.
本申请实施例提供一种充电系统及其方法、装置、电子设备和存储介质,其中,充电系统包括:电池模块、逆变模块、三相电机、充电模块、整流模块、充电接口和第一开关;逆变模块并联于电池模块的第一端和电池模块的第二端之间;逆变模块和三相电机连接,用于控制三相电机的工作状态;充电模块通过第一开关和三相电机的中性点连接;充电模块的第一端还和逆变模块的主正公共端连接;充电接口通过整流模块和充电模块连接。通过第一开关,可以实现充电和电机逆变的功能复用,充分发挥了电气集成化的优势,取消了充电模块的副边全桥功率器件,由电机逆变模块功能复用,大幅减少了功率器件的使用,有效降低了成本。
