Summary

Complaint The following symptoms with electrical range: • Displayed electrical range is implausible for charging process (SOC) . • Displayed electrical range reduces rapidly after short period of driving. • High-voltage battery can no longer charge. Cause The voltage difference (maximum cell voltage minus minimum cell voltage) within the high-voltage battery is too great (> 100 mV). In an extreme case, no individual cell voltages are displayed in the Battery Management System (BMS) anymore (signal not available). Remedy Replace high-voltage battery. Note on analysis for transportability: The transportability assessment should be conducted promptly, as the high self-discharge level means that an assessment at a later stage may no longer be possible. Conduct the transportability assessment using the diagnostic system, to do so, select menu item "Special procedures" -> see also WISnet AR54.10-P-1140SRE, operation step 2. The procedure, if no individual cell voltages can be read out (signal not available - SNA), is also described in the diagnosis procedure.
