Problems solved by technology
[0003] In the related technology, the new energy vehicle adopts a groove on the road surface to charge the vehicle. The technical solution is actually a concave arc surface groove installed under the road surface groove, and the receiver is charged in contact with the arc surface groove. The charging current contactor has complex structure and heavy weight, which affects the cruising range of the car body, and this technical solution is not suitable for use on rail vehicles

Description
technical field [0001] The invention belongs to the field of rail transportation, and in particular relates to a charging device for rail vehicles and a rail transportation system with the charging device. Background technique [0002] Existing rail vehicles usually use flexible catenary to take power, and use pantograph or shoe-rail contact charging. This way of taking power is arranged along the entire line of the power grid, and the investment cost of the way of taking power is generally high. For this, the energy storage charging method is adopted. The development potential of rail vehicles for small short-distance transportation is huge. [0003] In the related technology, the new energy vehicle adopts a groove on the road surface to charge the vehicle. The technical solution is actually a concave arc surface groove installed under the road surface groove, and the receiver is charged in contact with the arc surface groove. The charging current receiving contactor is co...
