Circuit/System Description

WARNING: This page is about a different variant/trim than selected.

Sixteen temperature sensors are used to monitor the battery temperature. The non-serviceable battery temperature sensors are located within the battery sections. Two temperature sensors are located in each battery section.

The hybrid/EV battery temperature sensor is a variable resistor that measures the temperature of the hybrid/EV battery cell groups. The hybrid/EV battery interface control module supplies 5V to the signal circuit and a ground for the low reference circuit. The hybrid/EV battery temperature sensor resistance changes with battery temperature. The lower the temperature, the higher the resistance of the sensor. The higher the temperature, the lower the resistance of the sensor. The hybrid/EV battery interface control module communicates the battery temperature values to the hybrid/EV powertrain control module 2 via serial data. The hybrid/EV powertrain control module 2 uses the battery temperature sensors to control the battery cooling system operation.
