Intelligent thermal control explosion-proof safety protection device for lithium battery

Abstract

The invention relates to a lithium battery intelligent thermal control explosion-proof safety protection device which is provided with an outer protection shell, an inner protection shell, an explosion-proof heat exchange module, a temperature controller, a three-color warning lamp and a buzzer, and the temperature controller, the three-color warning lamp and the buzzer are installed on the surface of the top of the outer protection shell. A heating resistance wire is wound on the outer side face of the inner protective shell, and a semiconductor chilling plate connected with the anti-explosion heat exchange module is fixed to the outer side face of the inner protective shell. A safe separation module is arranged on the outer side of the outer protective shell and is provided with a spring for throwing the lithium battery away from the vehicle in a deflagration state of the lithium battery; the three-color warning lamp and the buzzer are in circuit connection with the temperature controller, and the temperature controller receives and processes signals of the temperature sensor. The temperature of the lithium battery can be monitored in real time, intelligent thermal control can be performed on the lithium battery, it is ensured that the lithium battery is at the optimal working temperature, the danger degree of the lithium battery in the using process is judged and early warned, the personal safety of a vehicle and a user is ensured, and harm is reduced.

Description
