A vehicle includes a traction battery and an auxiliary battery. A battery management system may be configured to transfer energy from the traction battery to the auxiliary battery during an ignition-off period. A controller is programmed to, in response to detecting conditions during the ignition-off period inhibiting an energy transfer from the traction battery to the auxiliary battery while a voltage of the auxiliary battery is less than a threshold and the traction battery is decoupled from the auxiliary battery, output a low-voltage alert. Conditions inhibiting the energy transfer include a state of charge of the traction battery being less than a predetermined state of charge and a traction battery voltage being less than a predetermined value. The low-voltage alert may be output via a wireless communications network to a device remote from the vehicle to alert the operator of the condition.
