P0C33 Description

The battery temperature sensors are provided at 3 locations of the HV battery. The resistance of the thermistor, which is built into each battery temperature sensor, varies in accordance with changes in the HV battery temperature. The lower the battery temperature, the higher the thermistor resistance. Conversely, the higher the temperature, the lower the resistance. The battery smart unit uses the battery temperature sensors to detect the HV battery temperature, and sends the detected value to the power management control ECU. Based on the results of this detection, the power management control ECU controls the blower fan. (The blower fan starts when HV battery temperature rises above a predetermined level.)
