Embodiment 1

[0043] This embodiment discloses a wireless charging positioning device for electric vehicles, such as figure 1 As shown, including vehicle end unit and ground end unit.

[0044] The ground end unit is set in an area where electric vehicles can be charged, such as a charging station. The ground end unit includes a first controller, a positioning sensing board, a first motion drive device and a sensor, wherein,

[0045] The first motion driving device is connected to a first controller. In this embodiment, the first motion driving device is a mechanical arm, and the steering gears on each joint of the robotic arm are respectively connected to the first controller, and the first controller controls the rotation of the steering gear to control the motion state of the robotic arm. Specifically, the first motion driving device may be a six-joint mechanical arm. The number of steering gears is the same as the number of joints, which is also six. The six steering gears control the ...

Abstract

The invention discloses a wireless charging positioning device for an electric vehicle and a method thereof. The device includes a ground end unit and a vehicle end unit arranged on the electric vehicle. In the ground end unit, the primary side coil is installed on a first motion drive device and As the first motion drive device moves along the positioning induction plate, the primary side coil is connected to the power supply and powered by the power supply, the inductor is installed on the positioning induction plate and is connected to the first controller with the first motion drive device; In the end unit, both the secondary coil and the ranging sensor are installed in the second motion drive device and connected to the second controller, and the secondary coil is connected to the charging circuit of the electric vehicle battery to provide charging voltage for the electric vehicle battery. The invention can realize the precise positioning of the primary coil and the secondary coil and automatically and effectively wirelessly charge the electric vehicle.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a wireless charging positioning device for electric vehicles and a method thereof. Background technique [0002] With the development of cities and the advancement of science and technology, electric vehicles that can meet people's daily transportation needs have been developed and popularized. At the same time, wireless charging technology has also been promoted to a certain extent. At present, it is more common for electric vehicles to use traditional charging piles for wired charging. This method is simple and reliable, but the safety problems of excessive current and voltage of the charging connector and waterproof in rainy days are serious. The use of wireless charging technology to supply energy to electric vehicles can not only improve the problems caused by traditional charging pile power supply, but also has the advantages of small infrastructure investment, en...
