Buffering With buffering, vehicle functions (e.g. car radio, sliding roof, etc.) may be demonstrated
during the charging process. Please note the following:
-
The current used over a long period must be less than the charging current.
- If the charging current is less than the current used over a long period, the battery will
become discharged.
- The charging period is longer in buffering mode and may therefore trigger a safety cut-
out.
