AI Technical Summary

Technical Problem

Existing lithium-ion battery sensors are prone to displacement under vibration, leading to inaccurate monitoring data, affecting the BMS's judgment and decision-making on battery status, and increasing the risk of safety accidents.

Method used

A sensor mounting structure is designed, which forms an installation space through the sealed connection of a first sensor mounting base and a second sensor mounting base, fixes the outer edge of the sensor, and sets the communication connector along the axial direction of the sensor to avoid the battery terminals and busbars, thereby achieving stable connection and wiring.

Benefits of technology

It effectively reduces the possibility of sensor movement, improves the accuracy and stability of data acquisition inside the battery, and enhances the BMS's ability to monitor and warn of battery safety status.
