Wireless charging positioning system and method, electric vehicle, and wireless charging emitting system

Abstract

The invention discloses an electric vehicle wireless charging positioning system. The wireless charging positioning system includes a charging emitting end, a charging guide device, a charging positioning device, a charging receiving end, a positioning detection device, and a control device; the charging guide device generates a charging guide signal; the charging positioning device generates a charging positioning signal; the positioning detection device detects the charging guide signal and the charging positioning signal; the control device acquires a current operation parameter of an electric vehicle after receiving a charging start signal, generates a charging guide control signal according to the current operation parameter and the charging guide signal, generates a charging positioning control signal according to the charging positioning signal so as to position the charging receiving end and the charging emitting end; and the charging receiving end, the positioning detection device and the control device are arranged on the electric vehicle. The wireless charging positioning system is accurate in positioning, and can improve the charging efficiency. The invention also discloses an electric vehicle, a wireless charging emitting system, and a wireless charging positioning method.

Description

technical field [0001] The invention belongs to the technical field of vehicles, and in particular relates to a wireless charging alignment system for electric vehicles, an electric vehicle, a wireless charging transmission system, and a wireless charging alignment method for electric vehicles. Background technique [0002] With the rapid development of electric vehicles, users have higher and higher requirements for charging electric vehicles. For example, the distribution of electric vehicle charging stations, convenient charging of electric vehicles and wireless charging of electric vehicles. Among them, the wireless charging of electric vehicles is favored by more and more automobile manufacturers because of its safety and convenience. However, the wireless charging transmitter and receiver of electric vehicles need to be more accurately aligned during charging. The more accurate the positioning position, the higher the charging efficiency of the wireless charging syst...

Problems solved by technology

[0004] However, since the appearance and size of electric vehicles are not uniform, each reference marking line can only be used for one type of electric vehicle, and another electric vehicle can be replaced. The above reference marking lines are completely useless

In addition, for electric vehicles of the same model, due to personal technical reasons, it cannot be aligned at one time, and it needs multiple times to complete the alignment function, which is a waste of time and resources

Furthermore, environmental factors have a greater impact on the alignment method, such as heavy rain, smog and other weather, the marking line cannot be seen clearly, and alignment is more difficult
