Abstract

The present application discloses a charging and discharging circuit, a battery control circuit and an electrical device. The charging and discharging circuit includes: a power supply module, a first driving assembly, a second driving assembly and a first switch; the power supply module includes a battery, the first driving assembly includes a first motor, and the second driving assembly includes a second motor; the first driving assembly and the second driving assembly are connected in parallel between a positive electrode end and a negative electrode end of the power supply module; and one end of the first switch is connected to a neutral point of the first motor, and the other end of the first switch is connected to a neutral point of the second motor. According to the present application, the first switch is connected between the neutral points of the two motors, different circuit loops are formed by switching by controlling on and off of each switch in the circuit, so that more functions can be supported and achieved. A plurality of inductors can be connected between the neutral points of the two motors in series, and the inductors can be connected in parallel with the switches, so that the inductance in the charging and discharging loop can be flexibly adjusted, and different battery heating requirements are met by adjusting the circuit structure.
