Abstract

The invention provides an electric bicycle wireless charging system and relates to electric bicycles. The system comprises an emission end and a receiving end. The emission end is provided with an emission coil, a full-bridge high-frequency inverter circuit, an AC-DC switch power source, an emission end auxiliary power source, a primary side control circuit, a driving circuit, a primary side wireless communication module and a voltage regulating circuit. The emission coil is connected with a power supply network through the full-bridge high-frequency inverter circuit and the AC-DC switch power source. The receiving end is provided with a receiving coil, a rectifier filter circuit, a vehicle-mounted battery, a detection circuit, a receiving end auxiliary power source, a secondary side control circuit, a user interaction interface and auxiliary side wireless communication module, and the receiving coil is connected with the vehicle-mounted battery through the rectifier filter circuit. The receiving end auxiliary power source supplies power to the primary side control circuit and the secondary side control circuit. The input end of the voltage regulating circuit is connected with the output end of the primary side control circuit, and the output end of the voltage regulating circuit is connected with the AC-DC switch power source.

Description

technical field [0001] The invention relates to electric bicycles, in particular to a wireless charging system for electric bicycles. Background technique [0002] In recent years, electric bicycles have been welcomed by consumers, because they can achieve almost zero pollution and zero emissions, and have the advantages of green environmental protection, economy and convenience, which are very beneficial to environmental protection and air governance; at the same time, they are small and light, which is convenient for people travel by means of transportation. [0003] With the promotion of new energy sources, the advantages of electric bicycles are more obvious, and they are becoming more and more important in daily life. Existing electric bicycles all adopt wired mode charging, must have power supply and charging line. However, such a method has relatively large potential safety hazards, and electric leakage and electric shock accidents may occur during use, which may br...
