To solve a problem that it is difficult to simultaneously supply sufficient electric power to all vehicles on a charging road, in a conventional contactless charging system.SOLUTION: In a contactless charging system 10 of the present invention, when a charging road 11 has received a charging request signal from a traveling vehicle 12, the charging road 11 transmits a charging interruption request signal to other vehicles 12 which travel on the charging road 11. In the other vehicles 12, a vehicle control unit 21 determines whether or not the battery 24 needs to be charged, and stops charging to the battery 24 as appropriate; and thereby, it becomes possible for the capability of supplying electric power to power supply units 14A of the charging road 11 to respond to the above problem with normal specifications. This system enables preferential charging to the vehicle 12 which requires rapid charging just before running out of power, and prevents the occurrence of the vehicle 12 which runs out of power while traveling.SELECTED DRAWING: Figure 1

    【課題】従来の非接触充電システムでは、充電路上の全ての車両に対して、同時に、十分な電力の供給を行うことが難しいという課題がある。【解決手段】本発明の非接触充電システム10では、充電路11は、走行中の車両12から充電要請信号を受信した場合に、充電路11を走行するその他の車両12に対して充電中断要請信号を送信する。その他の車両12では、車両制御部21が、バッテリ24への充電の要否を判断し、適宜、バッテリ24への充電を停止させることで、充電路11の給電部14Aへの電力の供給能力が通常のスペックにて対応可能となる。このシステムにより、電欠直前の急速充電が必要な車両12への優先的な充電が可能となり、走行中に電力不足に陥る車両12の発生が防止される。【選択図】図1
