Charge control device, vehicle control device, vehicle, charge control method and vehicle control method

摘要

A charge control device for a battery is mounted on a vehicle, the vehicle comprises an engine, a generator driven with power of the engine, the battery configured to be chargeable with electric power generated by the generator, and auxiliary machinery operated with electric power of the battery. The charge control device comprises: a load condition detector that is configured to detect a load condition of the auxiliary machinery; and a charge controller that is configured to control charging into the battery, based on the load condition of the auxiliary machinery, wherein in response to detection of a state change from a state in which a magnitude of the load of the auxiliary machinery is smaller than a predetermined threshold value to a state in which a magnitude of the load is larger than the predetermined threshold value, the charge controller controls a generated voltage by the generator based on the magnitude of the load of the auxiliary machinery prior to the state change during a time period until a specified time has elapsed after the detection of the state change, and the charge controller controls a generated voltage by the generator based on a magnitude of the load of the auxiliary machinery detected by the load condition detector during a time period after elapse of the specified time.
