Abstract
Official abstract text for this publication.
A vehicle-mounted controller mounted on a vehicle includes communication state determination unit and a battery charging control unit. The communication state determination unit is configured to determine whether or not vehicle-mounted information equipment performs communication with external charging equipment or an external information device via a charging cable. The battery charging control unit is configured to control, in a case where the communication state determination unit determines that the vehicle-mounted information equipment performs the communication with the external charging equipment or the external information device via the charging cable, a voltage converter so as to charge a low-voltage battery by supplying electric power from a high-voltage battery to the low-voltage battery when a first specific time has elapsed since start of the communication. The high-voltage battery, the vehicle-mounted information equipment, the low-voltage battery, and the voltage converter are provided with the vehicle.
