CHARGE CONTROL DEVICE AND CHARGE CONTROL METHOD

A charge control apparatus controlling charge of a battery 3 comprising a charger 2 for charging a battery with rectified power obtained by rectifying AC power supplied from a power supply by full-wave rectification or half-wave rectification as charge power, a sensor 4 for detecting a state of the battery 3, and controller for setting voltage lower than limit voltage of the battery 3 as upper limit charge voltage chargeable to the battery 3 from the charger 2 and controlling the charger 2. The controller manages the power chargeable to the battery 3 as chargeable power on a basis of a detected value of the sensor 4 and the upper limit charge voltage, controls the charge power on a basis of the chargeable power, sets the upper limit charge voltage to first upper limit charge voltage when the charge power is higher than a predetermined threshold value, and sets the upper limit charge voltage to second upper limit charge voltage higher than the first upper limit charge voltage when the charge power is lower than the threshold value.
