Critical and non-critical battery modules


The condition of a battery module after a status change or an error may be critical or non-critical. A qualified person must assess on site whether a battery module is critical or non-critical.

  • Critical battery modules are potentially dangerous. The following symptoms serve as orientation:

    • The battery module has a notable smell, e.g. of plastic or gas.

    • Gases are leaking from the battery module.

    • The enclosure of the battery module is no longer closing properly and the inside of the battery module is visible.

    • The enclosure of the battery module is expanded or hot.

  • Non-critical battery modules are battery modules, for example, whose storage capacity is no longer sufficient.
