Currently on the market there have been a lot of wireless charging products. For example, mobile phone wireless charging, car wireless charging and so we are very familiar with these people, but for wireless charging electric bicycle may be known. Bicycle is a more environmentally friendly means of transport, and now we all advocate environmental protection. Electric bicycle can face a problem is the charge is very troublesome, and filled with electricity can not be long. For the electric bicycle race to go halfway suddenly no electricity is a common thing. So in order to solve this problem we researchers thought of wireless charging bicycle configuration of coil and the electromagnetic converter, when riding it through the paved road of the electromagnetic coil launching, the magnetic field is activated, and generate an electric current is bicycle use and storage. Therefore, it can be used to significantly reduce the volume and weight of the electric bicycle. Since this reduces a lot of trouble, but also let us very useful.
