Title:
NON-CONTACT CHARGING SYSTEM, POWER TRANSMISSION DEVICE, AND METHOD
Document Type and Number:
Japanese Patent JP2017184609
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a non-contact charging system capable of performing a recover of a system.SOLUTION: A non-contact charging system comprises: a power transmission side device including a power transmission part 102 and communication means 112; a power reception part 202; and a power reception side device including communication means 212 and switching means 206. The power transmission part transmits a minimum power to the poser reception part before a charging of a battery 201 connected to the power reception side device is started. The communication means of the power transmission device and the power reception side device establish a bi-directional radio communication by a communication passage without passing through the power transmission part and the power reception part under a condition that the minimum power is transmitted and received between the power transmission part and the power reception part. The switching means switches a state according to the battery from a first state that cannot perform charging to a second state that can charging under the condition that the power reception part receives the minimum power. When information indicating that the battery is in the second state by the communication means, the power transmission part transmits an electric power larger than the minimum power to the power reception part instead of the minimum power.SELECTED DRAWING: Figure 2
