Inductive charging system in which primary power source is stopped before secondary side charger

摘要

593562 Disclosed is a resonance type non-contact charging device. The device is comprised of a power source (13), a primary-side resonant coil (11), a secondary-side resonant coil (21), a charger (24) receiving power from the secondary-side coil (21), a battery (25) connected to the charger (24) and a stop control unit (14, 27). The primary-side coil (11) receives electric power from the power source (13). The secondary-side resonant coil (21) is arranged apart from the primary-side resonant coil (11) in a non-contact manner and receives electric power from the primary side resonant coil (11) through magnetic field resonance between the primary-side resonant coil (11) and the secondary-side resonant coil (21). The stop control unit (14, 27) stops the power source (13) before the charger (24) is stopped when charging is to be stopped.
