Chargeable electric device

摘要

A chargeable electric device (12) includes a rechargeable battery (35). A secondary coil (31) is arranged to be coupled by electromagnetic induction to a primary coil (26) of a non-contact charger (11) when charging the rechargeable battery (35). A resonance capacitor (32) is connected to the secondary coil (31). A rectification unit (33) is connected to the secondary coil (31). A charging current control unit (34) arranged between the rectification unit (33) and the rechargeable battery (35) controls charging current supplied from the rectification unit (33) to the rechargeable battery (35). A resonance obstruction element (36) obstructs normal resonance produced by the secondary coil (31) and the resonance capacitor (32) in synchronism with the control performed by the charging current control unit (34) to suppress the charging current.
