Switch fault detection method and device, battery system, equipment and storage medium

Abstract

The invention discloses a switch fault detection method and device, a battery system, equipment and a storage medium, and the method comprises the steps: controlling the connection and disconnection of bridge arms in a first motor controller and a second motor controller; according to the current of the first motor and the current of the second motor, whether the adjusting switch breaks down or not is determined; wherein the adjusting switch is connected between the first motor and the second motor, the first motor is connected with the first motor controller, and the second motor is connected with the second motor controller. According to the method, rapid and accurate fault detection can be carried out on the adjusting switch on the dual-motor neutral line, and the method is relatively low in cost and relatively high in reliability.
