Battery Temperature

The battery management system continuously monitors the battery temperature. The Sunny Island adjusts the specification of the current usable battery capacity and the charging voltage to the current battery temperature ( > Automatic Temperature Compensation).

The battery management system issues a warning message if one of the following events occurs:

  • The battery temperature is within 5°C of the maximum permissible battery temperature.

  • The battery temperature is less than -10°C.

If the maximum permissible battery temperature is exceeded, the Sunny Island switches off. As soon as the battery has cooled down to a specified temperature, the Sunny Island restarts.
