Description
Technical field
The present invention relates to a kind of automobile charger, be specifically related to the wireless electric vehicle charging device that travels based on solar photovoltaic powered.
Background technology
Since scientist discloses electromagnetic induction phenomenon, the transmission of electric energy is mainly directly contacted and is transmitted by wire.The charging of electrical equipment is generally to be undertaken by plug and socket, but when carrying out high-power charging, the danger that this charging modes exists high pressure to get an electric shock.Owing to there being friction and wear, have a certain impact to fail safe, the reliability band of voltage levels electric power system and shortened useful life of power equipment, when being powered to sports equipment, as the electric car in urban transportation, be generally to adopt the mode of sliding contact to be powered, this mode exists in the use such as skimming wear, contact sparking, carbon deposit and dangerous bare exposed conductor etc. drawback.
Day by day exhausted today in fossil energy, electric automobile is as the breach of the economic growth of a new round and realize the fundamental way that the transportation and energy makes the transition, having become the common strategic choice of each major country of the world and automobile manufacturing company, is also the strategic choice of various countries' automobile market.Under the promotion energetically of national governments, the world car industry entry period of comprehensive transportation and energy transition, electric automobile has entered the new stage of accelerated development.China has taked the action of a series of essence to start exploitation and the use of electric automobile.Stipulate before China to 2012 year to have 10% automobile to use and can replace fuel.Started " 863 plan " that be intended to the electric vehicle engineering research and development.The Department of Science and Technology has also announced a plan recently, will dispose 10,000 hybrid powers, electric power and fuel cell locomotives in 10 cities in the whole nation.Accelerate the electric automobile market operation, not only need ripe technology, longer course continuation mileage, sharp acceleration, more need a series of huge systems such as post-processed of charging station laying, battery to support the routine use of electric motor car, the quick charge station that especially spreads all over each corner, city is the key point that can electric motor car put goods on the market as early as possible.Electric automobile is in and is charged and inconvenience, even if can charge with 220 volts of voltages of family expenses, owing to existing wire to connect, the interface plug, the charging interval is long etc., and this contact charging modes has brought serious inconvenience to people's production and life, also there is certain hidden danger on safety, particularly limited in the flying power of the electrokinetic cell of electric automobile, the automobile that stop frequently charges the battery, and has affected the development of electric automobile.
Realize not having between electric power system and electric equipment the wireless power of conductor contact to become one of important research direction of delivery of electrical energy, particularly high power load is filled, powered, someone proposed the idea of wireless transmission of electricity very early, but but by a lot of scientists, was thought and can't realize at all.Because the electromagnetic energy that reflector sends disperses to transmit to surrounding, the mankind can't carry out centralized control to electromagnetic energy, just more out of the question are used.In November, 2006, the assistant professor of department of physics of Massachusetts Institute Technology (MIT) Sol Jia Xike (Marin Soljacic) proposes a kind ofly can utilize by the wireless power transmission technology new theory of electromagnetic energy.According to the theory of Sol Jia Xike, as long as allow the electromagnetic energy reflector produce resonance with receiving equipment on same frequency, between them, just can carry out exchange energy.Its leader's 6 people groups test on this theoretical foundation.Utilize two copper wire coils to serve as resonator, a coil is connected with power supply, as reflector; Another is connected with desk lamp, serves as receiver.Result, they successfully light one apart from 60 watts of electric lights over 2.13 meters of reflectors, but, the electromagentic resonance bulky coils, and two coils will be positioned over relative fixed position, simultaneously, through-put power only has 60 watts, and the efficiency of transmission of electric energy only has 40% left and right, and certain electromagnetic radiation etc. is arranged, can only be under test, can't carry out spread.
Solar-photovoltaic technology is widely used aspect a lot, become the important component part of regenerative resource, but solar energy power generating does not have not to be combined well utilization with New-energy electric vehicle, prior art is directly at the top of automobile, to lay photovoltaic array, but the automobile top area is limited, can't meet electric automobile electricity consumption demand, do not possess substantive application, the solar photovoltaic car power supply technique, wireless technology of transmission of electricity and quick charge technological deficiency have affected socioeconomic development, particularly affect the universal of electric automobile and promote, affect the realization of target for energy-saving and emission-reduction, above problem is urgently to be resolved hurrily.
