How can wireless charging be applied to electric vehicles? Below, we will finally propose a specific application method for wireless charging in electric vehicles through a simple research and analysis of charging locations, charging methods, and rechargeable batteries.

   First of all, the choice of charging location. Wireless charging technology is related to the distance and status of the charger and the device being charged, that is, the distance between the two cannot be too large, and there is no relative movement between the two, otherwise it will not be able to transmit power stably and effectively. Therefore, the charging location can only be the place where the car stays, that is, the garage, parking lot, intersection, etc. The charging device of the bus can also be set on the bus website. Of course, charging stations can be specially set up in places where conditions permit or beside highways to facilitate vehicle charging.

   Next, the choice of charging method. It can be seen from the three charging methods that the distance required for electromagnetic induction charging is too small, the efficiency of radio wave charging is too low, and the distance and efficiency of electromagnetic resonance charging can meet the needs of battery vehicles.

   Finally, the choice of rechargeable batteries. Electric vehicles are charged at any time in the city, so it is necessary to choose a battery that is pollution-free and has no memory effect for charging.

After comparison and selection, we have a clear idea about the application of wireless charging in electric vehicles: On the one hand, in the construction of roads and construction projects, the power supply unit will advance parking spaces and units at intersections and public parking lots according to the planning drawings. Or a wireless charging charger is embedded under the parking spaces and garages in the community, and the charger is connected to the grid or solar panels; on the other hand, the car manufacturer should install a wireless charging receiver on the bottom of the car and connect it with The battery and other equipment are connected; in addition, the relevant national departments must unify the frequency of transmitting and receiving signals to make them universal.

   Problems that should be paid attention to in the application and development of wireless charging technology

   1. The state must issue corresponding policies to encourage, support and regulate the development of wireless charging vehicles and the construction of charging facilities. The development of an industry or enterprise, especially an industry or enterprise that benefits the country and the people, is inseparable from the support of the state. Wireless charging is a field that has just started, and its effective development can largely solve a bottleneck in the development of electric vehicles, but due to the huge investment in its research and development, it needs more encouragement and support from the state to speed up its research and development process , So that it can be applied as soon as possible.

2. Regardless of the final charging method and the battery used, the state and various local authorities must conduct research on its frequency, safety, environmental protection, and energy saving to avoid waste, avoid adverse effects on human health, and avoid The environment is causing new pollution, and at the same time, it must be publicized to avoid people's fear of electromagnetics.

   3. In practice, since the transmitter is placed underground, care must be taken to protect it.

   4. In areas with a lot of rain, in addition to the waterproofing of underground facilities, the waterproof treatment of the vehicle receiving end is also an issue that needs to be considered.
