Problems solved by technology

One of the main problems at present is that wireless charging technology is only suitable for wireless charging of vehicles traveling at low speeds, and cannot meet the driving needs of vehicles traveling at high speeds
At the same time, the coupling between the generating device and the receiving device is poor, and the charging efficiency is low
When working, the frictional resistance caused is large and the energy loss is large

Abstract

The invention discloses a high-speed mobile suspension wireless charging system, which comprises a ground rail generating device, a suspension device, a suspension wireless generating device and a charging receiving device installed on a vehicle chassis. The invention adopts the magnetic levitation technology, after the generating coil of the device is coupled with the receiving coil of the vehicle, the moving speed of the generating coil of the device in the magnetic field is kept synchronous with the driving speed of the vehicle, realizing 100% coupling, and solving the existing problem of the prior art that can only satisfy low speed The wireless charging problem of driving vehicles can realize high-speed mobile charging. At the same time, the suspended wireless generating device can move left and right with the movement of the vehicle to achieve 100% coupling, which overcomes the energy caused by the low degree of coupling during the movement of the existing technology. Loss, significantly improve the charging efficiency.

Description

technical field [0001] The present invention belongs to the field of dynamic wireless charging, and in particular relates to a high-speed mobile floating wireless charging system. Background technique [0002] With the rapid development of China's automobile industry today, automobiles have entered thousands of households. Among them, electric vehicles are powered by on-board power supplies, driven by motors to drive wheels, and meet the requirements of road traffic and safety regulations. Electric vehicles use batteries to provide kinetic energy. Compared with traditional internal combustion engine vehicles, they have the advantages of energy saving, low noise, strong power, simple structure, and low maintenance costs. Environmental protection and air cleanliness are very beneficial, and the direct pollution is almost zero. When the battery power is insufficient, it needs to be charged in time. At present, the mainstream charging method is to use wired charging piles and c...
