An electric vehicle non-contact charging automatic guidance and control system and method

Abstract

The invention discloses an electric vehicle non-contact charging automatic guiding and control system and a method. The system comprises a non-contact charging device, a non-contact charging positioning device and a charging monitoring backstage, wherein the charging monitoring backstage communicates with the electric vehicle and the non-contact charging device respectively; the non-contact charging device comprises a vehicle-mounted electric energy receiving device and a ground electric energy transmitting device; the ground electric energy transmitting device carries out charging electric energy transmission and transmits the electric energy to the vehicle-mounted electric energy receiving device; the vehicle-mounted electric energy receiving device transmits the received non-contact charging electric energy to a power battery of the electric vehicle; and the non-contact charging positioning device is provided with the ground electric energy transmitting device. Rough charging vehicle positioning and accurate charging position are carried out via a vehicle charging guiding device and a vision precision positioning device, and a basis is provided for high-efficiency non-contact charging.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a non-contact charging automatic guidance and control system and method for electric vehicles. Background technique [0002] Under the influence of the dual factors of energy crisis and air pollution, the development and popularization of electric vehicles are vigorously advocated all over the world. With the support of new energy policies in my country, the demand for electric vehicles has grown rapidly, and the construction of charging and swapping facilities has also developed rapidly. Contactless The charging device does not need to connect the vehicle to the power supply system with a power plug, socket, cable, etc., and can directly charge it quickly. In addition, non-contact fast charging can be arranged in various places such as parking lots, residences, and roadsides, making it possible to charge electric vehicles anytime and anywhere. However, the non-contact charging d...

However, the non-contact charging device also has certain limitations, including short power transmission distance and low charging efficiency. The charging efficiency is especially affected by the transmission distance and positioning accuracy. the efficiency of the

[0003] Compared with the laboratory environment, the charging efficiency of non-contact charging equipment in practical applications has dropped significantly. The reason is that there is currently a lack of reasonable automatic guidance and charging control methods for non-contact charging of electric vehicles, resulting in the inability to fully utilize the non-contact charging equipment. The maximum efficiency of the contact charging device not only causes a huge waste of energy, but also affects the charging time
