The invention relates to a wake-up circuit for a vehicle battery. The wake-up circuit comprises a power supply module; an input pin; an output pin; a trigger module; the self-locking module comprises a control end, an input end and an output end, the control end of the self-locking module is connected to the output end of the trigger module, the input end of the self-locking module is connected to the power supply module, the output end of the self-locking module is connected to the output pin, and the output end of the self-locking module is connected to the output pin. The trigger module is configured to output a trigger signal to the self-locking module when receiving a gun insertion signal from the input pin, and the self-locking module is configured to switch on a current path between the power supply module and the output pin when receiving the trigger signal. Therefore, a stable wake-up signal is continuously output to the battery management system of the vehicle. The invention also relates to a battery management system comprising the wake-up circuit.
