Description
The battery management system (BMS) has limited charge rate until cell temperatures increase.
Potential Impact
The HV battery charge rate is limited by cold cell temperature, and input charge power is applied to heating the pack.
Set Condition
BMS_userChargeStatus is BMS_CHARGING, and BMS_minModeledPackTemp < BATT_COLD_ALERT_TEMP_THRESHOLD, and BMS_iTarget < BATT_COLD_ALERT_CURRENT_THRESHOLD.
Clear Condition
BMS_userChargeStatus is not BMS_CHARGING, OR BMS_minModeledPackTemp > BATT_COLD_ALERT_TEMP_HYST_THRESHOLD, OR BMS_iTarget > BATT_COLD_ALERT_CURRENT_HYST_THRESHOLD.
