Abstract

A vehicle includes a low-voltage battery, a high-voltage battery, and a converter that decreases voltage provided from the high-voltage battery to the low-voltage battery. A system controller of the vehicle is programmed to use the converter, in a key-off cycle, to charge the low-voltage battery a calibrated number of times that the low-voltage battery drops below a predefined state-of-charge threshold, and send a wireless notification a subsequent time the low-voltage battery drops below the threshold. A notification is sent to a predefined contact address when a periodically computed state of charge of a low-voltage battery of a vehicle falls below a predefined threshold. Using a converter, voltage provided from a high-voltage battery of the vehicle to the low-voltage battery is decreased to charge the low-voltage battery responsive to receipt from the contact address of a response indicating approval of the charge.
