Electric vehicle charging device: three non-contact charging ways

Electric vehicle charging device of automobile fuel filling station, can provide vehicles run continuously through repeated charging energy. When domestic began to vigorously build cable charging pile and charging stations, foreign emerging out of the three kinds of non-contact electric vehicle charging device, and entered the commercial operation in different degrees. What are the types of non-contact charging device? The basic principle of work is what? Charging efficiency, safety, convenience of it? These are people of concern. Non-contact charging device type contactless charging device of electromagnetic induction, magnetic resonance (NMR), microwave three ways. The advantages of non-contact charging device compared with electric cars, not only in traditional fuel cars use convenience, curb weight and limited driving ability, manufacture and use cost etc. There are many advantages, but also added fuel without consuming more time. Electric vehicle charging time is long, not only and replace the battery or by cable charging mode of charging pile, it does exist for the inconvenience. And rainy day job security issues, is worrying. Non-contact charging device does not need the vehicle with cable connected to the power supply system, can be directly on the quick charge. Combined with non-contact quick charge to decorate in the parking lot, house, road and other places, and for various types of electric ( Including the plug-in hybrid) Auto recharge service, make the electric vehicle charging whenever and wherever possible. For bus, charging infrastructure can be set in the terminal, hub station, transfer station location, use of temporary parking time can complete the quick charge. The work principle of non-contact charging device is an electromagnetic induction and electromagnetic induction way by sending and receiving coil wire between the transmission power, is one of the most close to the practical application of charge method. When sending coil of alternating current through the send ( Primary) And receiving ( Secondary) Produce variations between the two coils magnetic beam, resulting in the secondary coil induction electromotive force changing with magnetic beam, by receiving coil terminal external output alternating current.
