Description

technical field [0001] The invention discloses a new type of magnetically conductive rubber material, a magnetically conductive tire and a magnetically conductive tire charging belt system made of magnetically conductive rubber that can automatically and efficiently charge an electric vehicle during high-speed driving or stopping, and belongs to new energy sources. automotive field. Background technique [0002] The wireless non-contact charging technology has been realized in the laboratory more than ten years ago, and the short-distance non-contact charging technology has been applied in the chargers of telephones and various electric tools. There are two main technologies commonly used: one is electromagnetic induction coupling technology, and the other is electromagnetic resonance technology. There is also radio frequency or microwave technology, but because microwave wireless charging technology will cause harm to the human body, it is generally not commonly used in ci...

AI Technical Summary

Problems solved by technology

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 these wireless non-contact charging technologies used 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, the direct use of the existing wireless non-contact charging technology in the field of electric vehicles will also 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, since the pressure sensor cannot judge whether it is an ordinary car or an electric car, it still produces a large number of non-electric cars or cars that do not need to be charged. Electromagnetic radiation and waste charging power

To sum up, the shortcomings and supplements of the existing wireless non-contact electric vehicle charging technology and solutions include: 1. Low charging efficiency; 2. Large amount of radiation, resulting in electromagnetic radiation and energy waste
