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...

AI Technical Summary

Problems solved by technology

In addition, wireless charging cannot solve the problem of electric buses' need for large-capacity battery packs and short battery life

[0007] To sum up, the disadvantages of electric bus charging include: 1. The battery has a large volume and weight, which reduces the operating efficiency of the bus

2. Short battery life

For the wireless charging of electric buses, its disadvantages include: 1. The transmission distance between the ground and the chassis is large, and the transmission efficiency is low; 2. Metal objects on the ground have fire hazards; 3. A metal detection device needs to be designed separately, and the cost is high; 4. The space under the vehicle is limited, and the design of the electromagnetic field shielding system is more difficult
