Description

Wireless accurate charging device of electric automobile Technical Field The utility model belongs to the technical field of wireless charging, and particularly relates to a wireless accurate charging device for an electric automobile. Background With the increasing prominence of environmental pollution caused by fuel automobiles and the increasing shortage of petroleum resources, new energy automobiles are actively developed and popularized in all parts of the world, the new energy automobile industry is in a recovery period which is developed accordingly, and the conservation amount of the new energy automobiles in the market is steadily increased year by year. However, the new energy automobile is not easy to advance. On the one hand, the highest speed ratio of the vehicle is not higher than that of the fuel vehicle, the driving mileage is easy to cause anxiety of a driver, and the market competitiveness is weakened. At present, the traditional electric automobile mainly relies on to install wired electric pile in parking stall and charges, but this kind of charging mode has a lot of drawbacks.
