Live incidence rate

<0.01% (Extremely rare)

Vehicle messages

Battery is heating - Keep charge cable inserted
Charge rate will increase once battery is warm

Impact

The HV battery charge rate is limited by cold cell temperature, and input charge power is applied to heating the pack.

Description

The battery management system (BMS) has limited charge rate until cell temperatures increase.

Cause

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.
