Reset Range Life Model

Gen3/tasks/PROC_HVC_X_RESET-LIFE-MODEL

What this task does

This routine resets the High Voltage Controller (HVC) life model algorithm to enhance range estimations when an untrustworthy condition is detected. In cases where significant accumulated errors occur, this routine can reset the calculated amp-hour capacity (CAC) and/or life model histogram records, ensuring more accurate range predictions.

Service procedures

After HV Battery Replacement

Before running this routine, a Controller Area Network (CAN) Electronic Control Unit (ECU) redeploy needs to pass. After a High Voltage (HV) Battery replacement, this routine runs all required tasks.

Clear HVC Isolation Condition

Clears the High Voltage Controller (HVC) isolation counters and alerts BMS_a027_SW_Repeated_Isolation_Failure_In_Drive, BMS_a172_SW_Isolation_Failure_In_Drive_Warning, BMS_a123_SW_Internal_Isolation, and BMS_a124_Battery_Coolant_Flood, if set. This routine shall only be executed after repairing a HV system component for loss of isolation.
