The invention discloses a motor controller, a motor circuit, a discharging system, a discharging method, discharging equipment, a discharging system and an automobile. The motor controller comprises a plurality of first bridge arms and further comprises a first inductor and/or a second inductor. The first ends of the plurality of first bridge arms are connected with the positive electrode of the power battery through the first switch and are connected with the first end of the direct-current charging port; the second ends of the plurality of first bridge arms are connected with the negative electrode of the power battery and the second end of the direct current charging port; the first end of the first inductor is connected with the midpoint of a first bridge arm, and the second end of the first inductor is connected with the positive electrode of the power battery through the second switch; the first end of the second inductor is connected with the midpoint of a first bridge arm, and the second end of the second inductor is connected with the first end of the direct-current charging port through the third switch, so that the power battery can perform direct-connection charging, boost charging or buck charging on an electric load, and the first bridge arm is multiplexed; switching of different discharging functions can be achieved by adding the inductor and the switch, and the circuit is simple in structure, small in size and low in cost.

    本发明公开一种电机控制器、电路、放电系统、方法、设备、系统和汽车。电机控制器包括多个第一桥臂,还包括第一电感和/或第二电感;多个第一桥臂的第一端通过第一开关连接动力电池的正极,并连接直流充电口的第一端;多个第一桥臂的第二端连接动力电池的负极和直流充电口的第二端;第一电感的第一端与一第一桥臂的中点相连,第一电感的第二端通过第二开关连接动力电池的正极;第二电感的第一端与一第一桥臂的中点相连,第二电感的第二端通过第三开关连接直流充电口的第一端,可使动力电池可对用电负载进行直连充电、升压充电或者降压充电,且复用第一桥臂,通过增加电感和开关即可实现不同放电功能切换,电路结构简单,体积较小,成本较低。
