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 an electric car wireless charging positioning device and a method thereof. The device comprises a ground end unit and a car end unit arranged on an electric car, wherein in theground end unit, a primary side coil is arranged on a first movement drive device and moves along a positioning sensor board along with the first movement drive device, the primary side coil is connected to a power supply and is powered by the power supply, a sensor is arranged on the positioning sensor board, and the sensor and the first movement drive device are connected with a first controller; and in the car end unit, an assistant side coil and a distance measuring sensor are arranged on a second movement drive device and are connected with a second controller, and the assistant side coil is connected into a charging circuit of an electric car battery so as to provide charging voltage for the electric car battery. According to the electric car wireless charging positioning device andthe method thereof provided by the invention, the accurate positioning of the primary side coil and the assistant side coil can be realized, and the electric car is automatically and effectively wireless-charged.

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...
