Abstract

The invention discloses a suspension type wireless charging system of an electric bus platform. The suspension type wireless charging system comprises an electric energy emission device and an electric energy receiving device, wherein the electric energy emission device is arranged on the bus platform, the electric energy receiving device is arranged on an electric bus, the electric energy emission device comprises a linear motor, a position sensing adjustment system, a height adjustment arm, an emission coil, a primary electric energy adjustment device and a signal receiving processing system, and the electric energy receiving device comprises a receiving coil, a secondary electric energy adjustment device, a signal emission device, a vehicle-mounted battery pack, a vehicle-mounted display control device and a shielding device. The brand-new suspension type wireless charging system of the electric bus platform, proposed by the invention, can be used for an ordinary structural electric bus, the electric bus driving to the bus platform can be charged in a wireless way, the electric energy transmission efficiency can be effectively improved, the capacity of the battery pack is reduced, the service lifetime of a battery is prolonged, and the charging cost is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of wireless charging. More specifically, the invention relates to a suspension type wireless charging system for an electric bus platform, which can perform high-power wireless charging for an electric bus parked on the platform in a short time. technical background [0002] With the intensification of global warming, energy conservation and emission reduction has become the focus of attention around the world. Traditional fuel-powered buses can no longer meet the needs of energy conservation and emission reduction. Electric new energy buses can greatly reduce emissions or even achieve zero emissions. , which is not only conducive to energy saving and emission reduction, but also can effectively reduce operating costs. It has become the best choice for the public transportation system and has huge development potential in China. According to relevant statistics, the daily mileage of each bus in my country is...
