8. Charging Current Limitation of the Wallbox
Important Notes
• Use this setting option to limit the maximum charging current. Therefore, the duration of a HV Battery diagnostics
PRO can take more time.
• The one-off setting made will be saved. Therefore, the active charging current limitation will be indicated as a note
when starting a HV Battery diagnostics PRO.
• The maximum charging current of the wallbox (16 A or 32 A) will not be exceeded, even if the setting for the charging
current limitation should be higher than the maximum charging current of the wallbox.
• The setting of the charging current limitation will have an effect only if the wallbox is used for a HV Battery diagnostics
PRO. The current for standard charging of electric vehicles is not affected by this setting.
When does a charging current limitation make sense?
• Fuse blows out during charging procedure
The fusing of the electric supply is lower than the maximum possible charging current of the wallbox. The setting
makes sense if an adapter cable from 32A to 16A of another manufacturer is used and if the adapter cable is not rec-
ognized by the wallbox. Many wallboxes do recognize only original adapter cables of the wallbox manufacturer.
• Abortion of the HV Battery diagnostics PRO due to inconsistent charging current (Error: SOH_CON-
STANT_CHARGING_EXCEPTION)
Ensure the constant charging power during the charging procedure for a HV Battery diagnostics PRO. Charge man-
agement systems or electric power consumers with high capacity can briefly reduce the charging power. The deacti-
vation of charge management systems or cutting off electric power consumers with high capacity is the best solution
for this issue. If the cutoff is not possible a reduction of the charging current can help to successfully perform the HV
Battery diagnostics PRO. A reduction of the current limitation in intervals is recommended as the duration of the HV
Battery diagnostics PRO increases with the reduction of the charging current limitation.
NOTICE
It is recommended to limit the charging current only if there is a reason for that.
