PROTECTION DEVICES, PROTECTION CIRCUITS, AND BATTERY SYSTEMS

Abstract

The invention relates to the field of electronic control devices, specifically to protective devices, protective circuits, and battery systems. The protective device comprises a stationary contact element, a fixed assembly, a moving assembly, and an actuator, in which: the moving assembly can move relative to the stationary assembly, and the moving assembly includes a moving contact element; the moving assembly has an initial state and a driven state; when the moving assembly is in the initial state, the electrical connection between the moving contact element and the stationary contact element does not exist; when the moving assembly is in the driven state, the electrical connection between the moving contact element and the stationary contact element exists; the actuator is fixed to the stationary assembly, and the actuator can be activated to switch the moving assembly from the initial state to the driven state. The protective device can meet the requirements of short-circuit and discharge protection.
