Abstract
(EN)
In the present invention, a contactless power supply system (10) transmits power in a contactless manner between a power transmission device (20) provided on a road and a power reception device (30) provided on a vehicle, and charges a storage battery (12) provided in the vehicle. The power transmission device comprises: a plurality of power transmission units (20a-20c) each having single-phase or multi-phase power transmission coils (26u, 26v, 26w) and transmitting power in a contactless manner to the power reception device; a detection unit (SE1) that detects a power transmission unit which is not involved in power transmission among the plurality of power transmission units; a switching unit (22) that switches between energization and energization cutoff of an electrical path between one end and another end of the power transmission coils; and a control unit (60) that controls the switching unit so as to short-circuit the one end and the other end of the power transmission coil of the power transmission unit which is not involved in power transmission and which was detected by the detection unit.

Dans la présente invention, un système d'alimentation électrique sans contact (10) transmet de l'énergie sans contact entre un dispositif de transmission d'énergie (20) disposé sur une route et un dispositif de réception d'énergie (30) disposé sur un véhicule, et charge une batterie de stockage (12) disposée dans le véhicule. Le dispositif de transmission d'énergie comprend : une pluralité d'unités de transmission d'énergie (20a-20c) ayant chacune des bobines de transmission d'énergie monophasée ou polyphasée (26u, 26v, 26w) et transmettant de l'énergie sans contact au dispositif de réception d'énergie ; une unité de détection (SE1) qui détecte une unité de transmission d'énergie qui n'est pas impliquée dans la transmission d'énergie parmi la pluralité d'unités de transmission d'énergie ; une unité de commutation (22) qui commute entre l'excitation et la coupure d'excitation d'un trajet électrique entre une extrémité et une autre extrémité des bobines de transmission d'énergie ; et une unité de commande (60) qui commande l'unité de commutation de manière à court-circuiter la première extrémité et l'autre extrémité de la bobine de transmission d'énergie de l'unité de transmission d'énergie qui n'est pas impliquée dans la transmission d'énergie et qui a été détectée par l'unité de détection.
