Summary:

The charging device of the electric vehicle is equivalent to the filling station of the automobile fuel, and can provide the energy of the continuous operation of the vehicle through repeated charging. When the country began to build cable charging piles and charging stations in a big way, three kinds of non-contact electric vehicle charging devices emerged in foreign countries, and entered commercial operation to varying degrees. What types of non-contact charging devices are there? What is the basic working principle? How is its charging efficiency, safety and convenience? These are all people's concerns.

Type of non-contact charging device

The non-contact charging device has three modes: electromagnetic induction, magnetic resonance, and microwave.

Advantages of non-contact charging devices

Compared with electric vehicles, traditional fuel vehicles not only have many advantages in terms of convenience, maintenance quality, driving capacity, manufacturing and use cost, but also do not need to spend more time when refueling.

The electric vehicle not only has a long charging time, but also replaces the battery or uses a charging pile or the like to charge through a cable, etc., and there is indeed an inconvenience in operation. And the safety of rainy days is even more worrying.

The non-contact charging device does not require a cable to connect the vehicle to the power supply system, so it can be quickly charged directly. In addition, non-contact fast charging can be arranged in parking lots, houses, roadsides, etc., and can provide charging services for various types of electric (including external charging hybrid) vehicles, making it possible for electric vehicles to be charged anywhere, anytime. . For buses, charging facilities can be placed at terminals, hub stations, transfer stations, etc., and fast charging can be completed with a short parking time.
