摘要： A battery safety valve and temperature detection circuit, includes a battery, a temperature sensor, and a reference resistor that are connected in series to form a loop, and a safety valve sensor arranged outside a battery safety valve. The temperature sensor is arranged on the battery, voltage acquisition wires are connected to a positive electrode and a negative electrode of the battery respectively, a partial voltage acquisition wire is connected to a wire connected between the temperature sensor and a reference resistor, the voltage acquisition wires and the partial voltage acquisition wire are connected to corresponding voltage acquisition ports of an acquisition chip respectively. The safety valve sensor is connected in parallel to the reference resistor; and when the safety valve is open, a liquid in the battery is in contact with a bottom of the safety valve sensor, and the safety valve sensor is short-circuited.
