The power receiving ECU sets a power transmitting/receiving efficiency by performing a gradual changing process of a ratio of an output power of a rectifier to an output power of an AC/DC converter, and sends an output demand power obtained by dividing the charge demand power by the power transmitting/receiving efficiency to a power transmission ECU. The power transmission ECU controls the AC/DC converter and an inverter to control the output power of the AC/DC converter to the output demand power. This enables the battery to be charged with a charging power approximate to the charge demand power. As a result, this provides power transmitting/receiving so as to charge the battery with an adequate charging power."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Non-contact power transmitting/receiving system","description":"A battery ECU sets a charge demand power based on the state of a battery and sends the set charge demand power to a power receiving ECU.
