Background technique

Usually, manufacturers connect multiple single cells in series or parallel to form a module, and then connect multiple modules in series or parallel to obtain a battery pack; then pack and seal the battery pack to obtain a battery pack. Subsequently, a battery pack is installed on the vehicle, and the battery pack is used to provide power for the electric vehicle to ensure the safety of the entire vehicle.

Among them, the state of the battery pack affects the usability of the electric vehicle and the safety of the use of the vehicle; therefore, it is very important to monitor the state of the battery and find the battery fault in time. Since the inside and outside of the battery pack are completely sealed, the internal scene cannot be seen; therefore, temperature and humidity sensors, smoke sensors, etc. can be built in the battery pack to obtain the physical parameters of the battery; and then the state of the battery pack can be predicted based on the physical parameters collected by these sensors.

Since the deployed sensor can only collect the physical parameters of the battery at its location, it is obviously unrealistic to deploy sensors in every position in the battery pack, so the battery pack cannot be fully monitored.
