CONTROL APPARATUS, POWER SUPPLY CONTROL APPARATUS, CHARGE CONTROL METHOD, CHARGE CONTROL APPARATUS, AND POWER SUPPLY APPARATUS FOR VEHICLES

摘要

A control apparatus charging a storage battery is provided. A control apparatus controls charging from a power generator to a storage battery. A switch is provided on a first charge channel via which the power generator charges the storage battery, and a DCDC converter is provided on a second charge channel via which the power generator charges the storage battery. The DCDC converter steps up a voltage generated by the power generator, and applies the stepped-up voltage to the storage battery via an electric wire. A controller controls the switch and the DCDC converter such that, when a charge current value detected by an electric current detector becomes smaller than a predetermined value under a condition where the storage battery is being charged via the first charge channel, charging to the storage battery is switched to charging via the second charge channel.

1. A control apparatus that controls charging from a power generator to a storage battery, comprising:
a first charge channel and a second charge channel via which the power generator charges the storage battery; a switch that is provided in the first charge channel; a voltage converter that is provided in the second charge channel, steps up a voltage generated by the power generator, and applies the stepped-up voltage to the storage battery; an electric current detector that detects a charge current to the storage battery; and a controller that controls the switch and the voltage step-up circuit so that, when a charge current value detected by the current detector becomes smaller than a predetermined value under a condition where the storage battery is being charged via the first charge channel, charging to the storage battery is switched to charging via the second charge channel.
