Full alert identifier: VCLEFT_a561_LVBMSEFuseOvertemperature
Alert description
The Low Voltage Battery Management System (LVBMS) detects high temperature at the low voltage (LV) battery MOSFET (internal protection transistor).
Potential impact
The low voltage (LV) battery may show degraded performance or become unavailable due to high temperatures.
Set condition
The LVBMS MOSFET temperature has reached 100 deg C for 1 second.
Clear condition
The LVBMS is no longer reporting high MOSFET temperature.
