Abstract

The invention discloses an explosion-proof protection system of a power battery, which relates to the technical field of electric vehicle battery protection and comprises at least one unit battery and an explosion-proof protection device arranged outside the unit battery, the explosion-proof protection device comprises a thermistor attached to the surface layer of the unit battery; the strain gauge series resistor is wound on the peripheral side of the unit battery; the resistance measurement module is connected with the thermistor and the strain gauge series resistor and is configured to periodically and synchronously obtain the resistance value of the thermistor and the strain gauge series resistor; and the explosion early warning module is connected with the resistance measurement module and is configured to judge whether the unit battery has an explosion hidden danger or not according to the obtained current resistance value of the thermistor and the current resistance value of the strain gauge series resistor. According to the application, the unit batteries are monitored in real time by utilizing battery expansion and temperature change occurring before the power battery in the electric vehicle explodes, so that the explosion hidden danger of the power battery can be found in time, and the explosion-proof protection on the explosion of the power battery can be realized.

Description

technical field [0001] The present application relates to the technical field of electric vehicle battery protection, in particular to an explosion-proof protection system for power batteries. Background technique [0002] With the development and popularization of electric vehicles, the number of electric vehicles is increasing. As the power source of electric vehicles, power battery, the situation of safety accidents caused by its explosion is also on the rise, so it is necessary to monitor and warn the power battery before it explodes. [0003] The temperature of the battery of an electric vehicle will rise before it explodes. In related technologies, methods such as battery box structure optimization and charge-discharge balance are often used to prevent explosion of the electric vehicle battery. However, the battery box structure optimization method can reduce the probability of battery explosion by optimizing the battery box structure to reduce battery collisions duri...
