Abstract

The invention provides a deformation monitoring device and monitoring method for a battery pack, the deformation monitoring device comprises a deformation acquisition module, a control module and a high-voltage disconnection module, the deformation acquisition module is used for acquiring the deformation quantity of the outer envelope of the battery pack; and the control module is used for controlling the working state of the high-voltage disconnection module based on the deformation quantity. The deformation state of the outer envelope of the battery pack can be monitored in real time without being affected by the high-voltage power-on and power-off state of the whole vehicle, high-voltage connection of the battery pack can be disconnected after deformation reaches a certain degree, the arc discharge risk in the battery pack is reduced, faults caused by deformation of the battery pack can be effectively prevented, risks caused by deformation of the battery pack can be prevented, and the safety of the battery pack is improved. Safety and reliability of the battery pack are improved, and property safety and life safety of users are effectively protected.

Description

technical field [0001] The present disclosure relates to the field of battery technology, and in particular, to a deformation monitoring device for a battery pack, a battery pack, a monitoring method, a storage medium, and an electronic device. Background technique [0002] Many transmission fuel vehicle platforms directly change the power source of the vehicle from fuel to battery by replacing the engine structure with the power battery pack structure. As one of the important assemblies of electric vehicles, how to ensure the safety of the power battery has always been the key research direction of the researchers. When the power battery outer envelope (the envelope composed of the battery box frame, bottom guard and upper cover) is When the deformation is severe, the external structural parts of the battery will invade the battery, causing the battery to lose control. [0003] The battery pack safety warning method in the prior art generally places the pressure collection...
