Critical and non-critical battery modules

After an error or a status change (e.g., after a shock sensor is triggered), the condition of a battery module 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 has expanded or is hot.

  • The connectors of the DC lines are discolored or deformed.

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