Title:
POWER RECEPTION EQUIPMENT FOR RESONANCE-TYPE NON-CONTACT POWER SUPPLY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2011/142418
Kind Code:
A1
Abstract:
Power reception equipment (20) is provided with: a secondary side resonance coil (21b) which receives power from a primary side resonance coil (13b) of power supply equipment (10); and a rectifier (23) which rectifies the received power. The power reception equipment is further provided with: a secondary matching unit (22) which is provided between the secondary side resonance coil (21b) and the rectifier (23); a charger (24) to which rectified electric power is supplied; a power storage device (25) which is connected to the charger; and a control unit (26) which adjusts the secondary matching unit when the power storage device is being charged. The control unit stores, as data on a storage device (33), the relationship between the charge power from the power supply equipment during the power ascension phase and the matching status of the secondary matching unit (22) when charging. During the phase in which the power output from the supply equipment is reduced, the control unit adjusts, on the basis of the data stored in the storage device during the power ascension phase, the secondary matching unit (22) so as to reach a suitable status corresponding to the charge power.
