CHARGE CIRCUIT, CHARGE SYSTEM AND WIRELESS POWER RECEIVER

摘要

A charge circuit includes a battery part for mounting a chargeable battery, a charging part, and a controller. The charging part supplies a charge current to the chargeable battery mounted on the battery part based on a DC voltage which an AC voltage is changed into, and charges the chargeable battery. The controller controls the charge part with a charge current. Based on the charge current, the battery voltage of the chargeable battery, and the temperature of the chargeable battery, in the first range of at least first charging mode, the charge current is the first charge current which fallows a first current profile in the first charge mode which is less than an available maximum current.
