Non-contact charge control system, non-contact charge control device, and non-contact charge control method

摘要

PPROBLEM TO BE SOLVED: To efficiently and certainly charge a secondary battery of electronic equipment with a secondary coil regardless of a positional relationship between a primary coil of a power transmission side and the secondary coil of a charging side. PSOLUTION: A charger 200 with the primary coil 221 and the secondary coil 111 are included, a first current value is acquired from the charger 200 through the primary coil 221 and the secondary coil 111, and an internal battery 300 is charged. The electronic equipment includes a non-contact charge control device 100 to charge the battery 300. The non-contact charge control device 100 includes a rectification smoothing circuit 110 which acquires the first current value through the secondary coil 111, a plurality of switching units 151 to 154 which designate a second current value of the battery 300, a control unit 140 which compares the first current value with a third current value set in advance and selects a first switching unit from the plurality of switching units 151 to 154, and a charge control unit 120 which controls the first current value acquired from the rectification smoothing circuit 110 to the second current value designated by the first switching unit and provides the current value to the battery 300.
