　　Application of wireless charging in electric vehicles

　　How is wireless charging applied to electric vehicles? Below, we will briefly study and analyze charging locations, charging methods, and rechargeable batteries, and finally propose specific application methods for wireless charging in electric vehicles.

　　First, choose the charging location. Wireless charging technology is related to the distance and status of the charger and the device being charged. That is to say, the distance between the two cannot be too large, and there is no relative movement between the two, otherwise power cannot be transmitted 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 up at the bus site. Of course, special charging stations can also be set up in places or beside highways where conditions permit to facilitate vehicle charging.

　　Secondly, 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 and the efficiency of radio wave charging is too low, while the distance and efficiency of electromagnetic resonance charging can meet the needs of battery cars.

　　Finally, the choice of rechargeable batteries. Electric vehicles will be charged at any time in the city, so it is necessary to choose a non-polluting and non-memory effect battery for charging.

　　After comparison and selection, we have a clearer idea of 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 pre-install parking spaces and units at intersections and public parking lots according to the planning drawings. Or bury wireless charging chargers under community parking spaces and garages, and connect the chargers to the power grid or solar panels; on the other hand, car manufacturers should install wireless charging receiving devices at the bottom of the car and connect them with Connect batteries and other equipment; in addition, relevant national departments must unify the frequency of transmitting and receiving signals to make them universal.

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

　　1. The state should 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, cannot be separated from the support of the state. Wireless charging is a field that has just started. Its effective development can largely solve a bottleneck in the development of electric vehicles. However, due to the huge investment in its research and development, it requires 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. No matter what charging method is used and what kind of battery is used, relevant national and local departments must conduct research on its frequency, safety, environmental protection, energy saving and other aspects to avoid waste, adverse effects on human health, and adverse effects on human health. The environment will cause new pollution, and publicity must be in place to avoid people's fear of electromagnetics.

　　3. In practice, since the transmitter is placed underground, attention should be paid to its protection.

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