VCLEFT_a513 — LVBMS Fault MOS Open chg OC

Full alert identifier: VCLEFT_a513_LVBMSFault_MOS_Open_chgOC

Alert description

The low voltage battery management system (LVBMS) reports it has opened the low voltage (LV) battery internal protection transistor (MOSFET) after detecting a charge overcurrent condition.

Potential impact

The LV battery may be damaged and may be unable to support vehicle electrical systems.

Set condition

The LVBMS detects a charge overcurrent condition affecting the LV battery.

Clear condition

The LVBMS reports the charge overcurrent condition is resolved and internal protection transistor (MOSFET) has been requested closed again.
