Embodiment Construction

[0019] A set of primary and secondary electromagnetic mutual inductance coils are respectively wound on the magnetic conductive material, and the primary and secondary turns ratios are calculated according to the primary and secondary voltages. A set of infrared scanning positioning control system is customized by using the existing technology, and it can also be a laser scanning positioning control system. In this example, an infrared scanning positioning control system is adopted. In addition, a set of wireless transceivers, manipulators, voltage detection devices and rectifiers are also customized.

[0020] The car-end components installed on the electric vehicle are mainly composed of a battery voltage detection device, a wireless transmission device, a secondary electromagnetic mutual inductance coil and a rectifier. The charging end component is mainly composed of an infrared scanning positioning control system, a manipulator, a primary electromagnetic mutual ind...

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging, in particular to an automatic wireless charging method and a complete device for an electric vehicle. Background technique [0002] Electric vehicles are in line with the national energy policy and are being gradually popularized. The electric vehicle needs to charge the battery after driving for a certain distance. The current charging method is to park the electric vehicle near the charging device, and insert the output cable of the charging device into the charging socket of the electric vehicle for charging. Because the charging plugs and sockets need to be plugged and unplugged frequently, it will cause poor contact or increase in contact resistance over time, prolong the charging time, and affect the normal driving of the vehicle. In addition, it will seriously affect the normal travel of the driver because the driver forgets to charge. SUMMARY OF THE INVENTION [...
