VCFRONT_a213 — LV Overcharge
Full alert identifier: VCFRONT_a213_LVOvercharge
Alert description
Over multiple discharge and recharge cycles, the low voltage (LV) battery has been overcharged by more than 5 Amp hours (Ah) compared to initial charge level. Indicates a condition affecting LV battery performance that makes replacement necessary (another alert specific to replacement should be present). May also indicate aftermarket device(s) installed on the vehicle, whose current draw interferes with LV battery management.
Potential impact
The LV battery may enter thermal runaway if the chronic overcharge condition is not resolved. The LV battery requires replacement, with a separate alert present to directly indicate that condition.
Set condition
Over multiple charge cycles, the LV battery has recharged by more than 5Ah compared to the energy initially discharged.
Clear condition
The LV battery is replaced and the vehicle controller is reset.
