In order to increase testing coverage and the efficiency of the power storage battery industry, Chroma ATE has developed an automated inspection system that can be applied to the EOL (End Of Line) of battery packs production for testing the assembly defects, Battery Management System (BMS) communication, internal power switches, battery balancing circuits/consistency, and temperature distribution, etc. before battery packs are shipped out of the factory.

The comprehensive PASS/FAIL tests can not only be used in production lines, but may also be used in a development phase nearing completion or used during battery pack acceptance inspection for EV or energy storage station.
