DTC P0A82 (63): Battery Module Overheating: General Description

To control the battery module temperature, the IMA (integrated motor assist) system is equipped with a battery module fan. The motor assist stops regeneration and the IMA system is shut down when there is an increase in the battery module temperature because the battery module fan is malfunctioning. Therefore, a malfunction in the battery module fan is detected to avoid problems caused by overheating. If the battery module cooling system works normally when the battery module temperature is high and the battery module is in the power save mode, the battery module temperature decreases depending on the input/output current.

If the amount of decrease in the battery module temperature is out of a set value when comparing both the input/output current and the battery module temperature with their predetermined values, a malfunction is detected and a DTC is stored.
