Abstract
A battery charge control apparatus to be installed in a vehicle includes a current regulation circuit and a controller. The vehicle is provided with a first battery, a voltage converter, a second battery, and an onboard device. The voltage converter lowers an output voltage of the first battery. The second battery is electrically charged by an output from the voltage converter and outputs a voltage lower than an output voltage of the first battery. The onboard device is operated by an output from the second battery and an output from the voltage converter. The current regulation circuit is disposed between the voltage converter and the second battery and reduces an amount of a charging current to be delivered via the voltage converter to the second battery. The controller controls the current regulation circuit on the basis of an output current from the voltage converter.
