Description
Technical field
The present invention relates to charging pile field more particularly to a kind of multi-functional charging piles based on radio frequency identification.
Background technology
Traditional energy automobile gradually shows its irreconcilable drawback after developing centuries.First, traditional energy automobile
Quantity increase, used excessive petroleum resources, and petroleum resources itself are to be difficult to regenerated, are to form global energy crisis
One of key factor；Secondly, traditional energy automobile is necessarily required to transmitter, causes body of a motor car larger, occupies excessive sky
Between, heavy congestion is caused to city；Again, the exhaust emissions of traditional energy automobile brings pollution to ambient enviroment, when serious very
To leading to haze；Finally, traditional energy automobile can also bring noise problem, and to surrounding cities, resident brings noise pollution,
The severe jamming normal life of city dweller.
Various problems based on traditional energy automobile, people are also in the substitute products for actively finding traditional energy automobile.Its
In, electric vehicle is gradually received because of haing the following advantages by people：1. zero-emission.Pure electric automobile uses electric energy, is expert at
Middle no exhaust gas discharge is sailed, it is free from environmental pollution.2. electric vehicle drives the energy utilization rate of automobile high than gasoline engine.3. because using
Single electric energy eliminates engine, speed changer, fuel tank, cooling and exhaust system, so structure is simpler.4. noise is small.
5. automobile charging can be carried out in electricity consumption ebb, the peak-valley difference of power grid can be stabilized, generating equipment is made to be fully used.
Electric vehicle, relatively for fuel-engined vehicle, essential difference (different) is four big components, driving motor, speed regulating control
Device, power battery, onboard charger.For gas station, he is completed to charge by public charging pile.The quality of electric vehicle
