Batt. Low Temp.

Batt. Low Temp.

This alarm is generated only for the power system that has a battery temperature sensor installed.

Possible Causes

  • The low battery temperature alarm threshold is incorrectly set on the SMU.
  • The battery temperature control system is faulty.
  • The battery temperature sensor is faulty.


  1. Check whether the low battery temperature alarm threshold (-10°C by default) is correctly set. If not, set the threshold to the correct value.
  2. Check whether the temperature control system for the battery compartment is faulty. If so, rectify the fault. The alarm is cleared when the temperature in the battery compartment becomes normal.
  3. Check whether the battery temperature sensor is faulty. If so, replace the battery temperature sensor.
