Electric automobile charging pile based on infrared positioning and magnetic principles and charging method of charging pile

Abstract

The invention discloses an electric automobile charging pile based on infrared positioning and magnetic principles and a charging method of the charging pile. The electric automobile charging pile comprises a pile body, the pile body is provided with an infrared camera, a main control chip, a driving module, an x, y and z linear mechanical device, a power supply module, a charging module and a charging gun, the infrared camera is connected with the main control chip through electric signals, coordinate information of an automobile charging interface is detected and transmitted to the main control chip, the charging gun is mounted on the x, y and z linear mechanical device, the x, y and z linear mechanical device can correspondingly drive the charging gun to move along three mutually perpendicular coordinate directions of an X axis, a Y axis and a Z axis according to the coordinate information of the automobile charging interface, the charging gun is provided with an electromagnet unit,and the electromagnet unit can attract or repel a permanent magnet of the automobile charging interface under control of the main control chip, so that corresponding positioning charging or disconnection is achieved.

Description

technical field [0001] The invention relates to the technical field of intelligent charging piles, in particular to an electric vehicle charging pile based on infrared positioning and magnetic principles and a charging method thereof. Background technique [0002] As the global auto industry is facing huge challenges of energy and environmental issues, there has been a broad international consensus on the development of new energy electric vehicles, the electrification of automotive energy and power systems, and the promotion of the strategic transformation of the traditional auto industry. At present, my country has introduced many policies to support and guide the rapid development of the electric vehicle industry. The government expects to accelerate the improvement of the competitiveness of the domestic electric vehicle industry, shorten the maturity period, and realize the "curve overtaking" of the foreign automobile industry. The development of electric vehicles has en...

AI Technical Summary

Problems solved by technology

[0004] (1) For larger charging stations, the distance between the charging pile and the charging machine is relatively long, and the construction workload and cost are relatively high;

[0005] (2) There is a large power loss on the long DC cable, which makes the charging process take too long and the charging speed is slow;

[0007] (4) The charging pile works under the long-distance communication control of the charging machine, and the reliability and safety of the system are reduced

[0008] (5) Existing charging equipment will generate large harmonics during operation, and the generated harmonics will not only pollute the power grid and increase the loss of transmission lines such as cables, but also reduce the power factor of the charging equipment, resulting in a decline in communication quality

[0009] (6) The intelligence of the charging pile is low, and the user needs to hold the charging gun and connect the charging connector of the car to achieve charging.
