Charging and discharging tests of batteries, such as lithium-ion batteries, are important tests to evaluate the life of batteries.

During the test, there is a possibility of gas leakage from the battery, ignition, smoking, or destruction.

The Advanced Battery Tester is a completely new battery charge-discharge tester with an integrated charge-discharge system and chamber. This system has four functions (performance test, endurance test, temperature characteristic test, and impedance evaluation) to make the most of the battery characteristic evaluation.

One unit with four functions. Introducing an all-in-one safety tester. The function elements of the safety tester are in separate modules, enabling flexible system construction and expansion. The combination of each unit enables support of batteries from small cells to large packs.

Charge-discharge tests of automotive secondary batteries have problems of being unable to perform accurate evaluation and having differences in environment temperature due to high heating of the battery during high input-output characteristic measurement and increased heat generation caused by battery degradation during long cycle and life testing.
