Improving quality of EV battery module and pack assembly process
Capacity variation issues during battery cell production can lead to poorly assembled battery packs. OMRON offers cell sorting to construct batteries from cells with same capacities eliminating the effect of cell capacity variations in order to optimize the performance of the cells.
Challenge
Capacity varies from battery cell to battery cell, which can lead to overcharge, over discharge, and overcurrent to battery packs. The capacities of cells in protective circuits should be equal to avoid this problem.
Solution
Our solutions provide traceability for individual products by quickly and reliably reading and writing data on cell capacity and characteristics during the manufacturing process. OMRON has extensive expertise in the area of traceability and data applications essential to the EV battery manufacturing process. The RFID technologies developed through our years of experience in automotive manufacturing helps to minimize configuration, operation, and maintenance effort.
