CONTACTLESS POWER TRANSMISSION SYSTEM AND ELECTRIC TRANSMISSION DEVICE

摘要

A power reception unit (100) includes a resonance circuit for contactlessly receiving electric power output from power transmission units (700A to 700C). Each of the power transmission units (700A to 700C) is configured to be able to form a plurality of resonance circuits having circuit configurations different from each other. A communication unit (510) transmits information about a configuration of the resonance circuit of the power reception unit (100) to a communication unit (810). A power supply ECU (800) controls the power transmission units (700A to 700C) such that a resonance circuit of the plurality of resonance circuits which has a circuit configuration identical to that of the resonance circuit of the power reception unit (100) is formed in the power transmission units (700A to 700C).
