Resonance type non-contact charging device
First Claim
1. A non-contact power reception device that receives electric power from a power transmission device having a primary side coil receiving electric power from a power source, the non-contact power reception device comprising:
- a secondary side coil configured to receive electric power from the primary side coil through a magnetic field;
a charger configured to receive the electric power received at the secondary side coil; and
a control unit configured to stop the charger after the power source is stopped when charging is to be stopped.

Abstract
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.
