Japanese Patent JP6384566
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a non-contact power transmission and reception system, including a power reception apparatus which receives electric power from a power transmission apparatus in a non-contact manner and which is capable of charging a battery, that suppresses the power reception apparatus and peripheral apparatuses thereof from becoming relatively hot temperature while suppressing enlargement of the power reception apparatus or the like and increase in the number of parts.SOLUTION: A non-contact power transmission and reception system calculates a loss Plo as power difference between transmission power Ptr of a transmission unit of a power transmission apparatus and reception power Pre of a reception unit of a power reception apparatus (S130) and, when the calculated loss Plo is higher than a threshold value Ploref, a value smaller than a value when the loss Plo is not higher than the threshold value Ploref is set to target transmission power Ptr* (S140-S170) to control a high-frequency power supply circuit by using the target transmission power Ptr* (S180).SELECTED DRAWING: Figure 3
