Sub Battery Temperature Sensor

Sub battery temperature sensor is integrated in battery current sensor.

The sensor measures temperature around the battery.

This sensor uses a thermistor and its electrical resistance varies as the temperature varies. EMCM detects a voltage change caused by the change in electrical resistance.
