CONTACTLESS CHARGE CONTROL SYSTEM, CONTACTLESS CHARGE CONTROL APPARATUS, AND CONTACTLESS CHARGE CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To provide a contactless charge control system capable of efficiently and surely charging a secondary battery of an electronic apparatus including a secondary coil independently of positional relation between a primary coil on the power transmission side and a secondary coil on the charging side in a contactless charge system.SOLUTION: A first current value is acquired from a charger 200 through a primary coil 221 and a secondary coil 111 to charge an inner battery 300. A contactless charge control apparatus 100 includes: a rectifying and smoothing circuit 110 for acquiring a charging current of the first current value through the secondary coil 111; a plurality of switching parts 151-154 for specifying a second current value of the charging current to be supplied to the battery 300; a control part 140 for selecting a first switching part from the plurality of switching parts 151-154 on the basis of comparison of the first current value with a third current value which is previously set for charging the battery; and a charge control part 120 for controlling the charging current of the first current value acquired from the rectifying and smoothing circuit 110 to the second current value specified by the first switching part and providing the charging current of the second current value to the battery 300.
