Advanced Battery Chamber Next

  • Overview of Equipment
  • Features

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.

In addition, when charge-discharge testing several batteries installed in the test area at the same time, deviations in temperature uniformity and heat generation of a battery to be cause of changes in the heat history of the batteries, thereby hindering correct evaluation.

In an effort to solve these problems, ESPEC applied its long-cultivated environment control technology to develop the Advanced Battery Chamber Next (precision temperature control chamber) with multi-area temperature control.
