VCFRONT_a533 — T LVBMS Mosfet Over Temperature Fault

Full alert identifier: VCFRONT_a533_TLVBMS_MosfetOverTemperatureFault

Alert description

The Low Voltage (LV) battery internal protection transistor (MOSFET) temperature is greater than the temperature limit.

Potential impact

There may be a loss of LV battery pack power. This alert may indicate a high impedance or other conditions affecting the expected operation of the LV battery MOSFET.

Set condition

The MOSFET temperature is greater than the expected set temperature limit for longer than expected.

Clear condition

The MOSFET temperature is within the expected temperature threshold.
