Patent number: 8212520Abstract: A resonance type non-contact charging device includes a high frequency power source, a primary side resonant coil, a secondary side resonant coil, a charger, a secondary battery, and a stop control unit. The primary side resonant coil receives supply of high frequency electric power from the high frequency power source. The secondary side resonant coil is arranged apart from the primary side resonant coil in a non-contact manner. The secondary side resonant coil receives electric power from the primary side resonant coil through magnetic field resonance between the primary side resonant coil and the secondary side resonant coil. The charger receives supply of high frequency electric power from the secondary side resonant coil. The secondary battery is connected to the charger. The stop control unit stops the high frequency power source before stopping the charger when charging is to be stopped.Type: GrantFiled: December 24, 2009Date of Patent: July 3, 2012Assignees: Kabushiki Kaisha Toyota Jikoshikki, Toyota Jidosha Kabushiki KaishaInventors: Kazuyoshi Takada, Sadanori Suzuki, Kenichi Nakata, Shimpei Sakoda, Yukihiro Yamamoto, Shinji Ichikawa, Tetsuhiro Ishikawa
