Battery Temperature Sensor

The battery temperature sensors are installed inside the battery pack. They measure the temperature inside the battery pack and the intake temperature.

The sensor uses a thermistor with a resistance value that varies according to changes in temperature. The electrical resistance of the thermistor decreases as the temperature increases.
