With the rapid development of the new energy vehicle market, the testing of the performance and safety of the battery core module as a core component is particularly important.
With the rapid development of the new energy vehicle market, the testing of the performance and safety of the battery core module as a core component is particularly important.
Fix a single electric core in a three-piece steel tooling, add aerogel felt boards for heat insulation between the electric core and the steel plate, put the sensor close to the side wall of the tooling, and place the mounted tooling in a constant temperature box at 25 ° C. Through multiple charging and discharg- ing cycles, we view the measured images and data to determine the pressure changes of the power battery during its entire life cycle, and thus judge the battery’s health level.
From the whole charging and discharging process, it is found that the film pressure measurement system can accurately find out where the problem of abnormal bulging of the battery cell lies, and detect the abnormal pressure area of the battery cell in the charging and discharging process, and through the test data, it can enable the R&D personnel to make further improvement for the problem of the battery cell to improve the safety of the battery.
