Description

technical field [0001] The present invention provides a brand-new electromagnetic auto-focusing wireless charging belt technology for charging electric vehicles at high speeds, a wireless charging belt control system and a technical implementation plan, as well as the laying construction equipment and laying construction method of the wireless charging belt , which belongs to the field of new energy vehicles. Background technique [0002] With the development of electric vehicle technology, the charging problem of electric vehicles will become increasingly prominent, and even become the throat that restricts the popularization of electric vehicles. Charging piles can solve the problem of charging electric vehicles while parked, but due to the relatively long charging time, it is difficult to solve the problem of charging during travel. The wireless non-contact charging technology has been realized in the laboratory more than ten years ago, and the short-distance non-contact...

AI Technical Summary

Problems solved by technology

The three technologies have their own advantages and disadvantages. Microwave technology can transmit energy at a relatively long distance, but high-power microwaves have certain damage to the human body; electromagnetic resonance technology can transmit energy at a distance of tens of centimeters, but the transmission power is relatively free of electromagnetic coupling. Large technology; electromagnetic coupling technology is more suitable for high-power energy transmission, but the environment used is close distance: the distance between the charging transmitter and receiver is less than tens of millimeters

Since the charging efficiency of the existing wireless non-contact charging technology is inversely proportional to the square of the distance between the charging transmitter and the receiver, the farther the distance is, the lower the efficiency is, and the distance between the site of an electric vehicle and the road is generally 200-500 mm Therefore, the charging efficiency of the existing wireless non-contact charging technology in the field of electric vehicles is relatively low

It was also proposed to install a height-adjustable bracket under the chassis of the car to reduce the distance between the receiving antenna and the road. This method is acceptable for non-contact charging in the parking lot when the electric car is stationary, but for high-speed For electric vehicles in motion, if the distance between the receiving antenna and the road is too small, any bumps will cause serious safety hazards

In addition, if the existing wireless non-contact charging technology is directly used in the field of electric vehicles, it will cause serious electromagnetic radiation and energy waste.

Someone once proposed to use the pressure sensor to detect the passage of the vehicle before turning on the charging current. However, it still generates electromagnetic radiation and wastes charging energy for a large number of non-electric vehicles or vehicles that do not need to be charged.

Moreover, the direct application of existing wireless non-contact charging technology solutions in the field of electric vehicles still has a series of problems such as complex implementation and construction, which is not conducive to large-scale and large-area construction.

To sum up, the shortcomings and deficiencies of existing wireless non-contact charging technology include: 1. Low charging efficiency; Cause electromagnetic radiation and energy waste
