MULTIPLE CURRENT-COLLECTING COILS FOR WIRELESSLY CHARGING ELECTRIC VEHICLES AND INDUSTRIAL EQUIPMENT AND CURRENT-COLLECTING DEVICE COMPRISING SAME

The present invention relates to multiple current-collecting coils for wirelessly charging in-motion or stationary electric vehicles and industrial equipment, such as electric buses or electric cars, and a current-collecting device comprising same, the multiple current-collecting coils allowing, per unit area, high-capacity and high-efficiency wireless charging by comprising: central coils disposed in the center; wing coils disposed on both sides of the central coils; and outer coils disposed on the boundary, enclosing the central coils and wing coils. La présente invention concerne des bobines multiples de collecte de courant pour la charge sans fil de véhicules électriques en mouvement ou stationnaires et d'équipements industriels, tels que des autobus électriques ou des voitures électriques, et un dispositif de collecte de courant les comprenant, les bobines multiples de collecte de courant permettant, par unité de surface, une charge sans fil à haute capacité et à haut rendement en comprenant : des bobines centrales disposées au centre ; des bobines latérales disposées des deux côtés des bobines centrales ; et des bobines externes disposées à la périphérie, entourant les bobines centrales et les bobines latérales. 본 발명은 전기 버스 또는 전기 승용차와 같은 전기 차량과 산업용 장비의 정차 또는 주행 중 무선충전을 위한 멀티 집전코일 및 이를 구비한 집전장치에 관한 것으로서, 중앙에 배치된 중앙코일, 중앙코일의 양측에 배치된 날개코일, 및 중앙코일과 날개코일을 포함하여 외곽에 배치된 외곽코일을 포함하는 멀티 집전코일로 구성됨으로서, 단위면적 대비 고용량, 고효율의 무선충전이 가능한 효과를 가진다.
