Description
Technical field
The invention discloses a kind of dynamic magnetic coupled resonance array technique supporting electric automobile wireless mobile to charge, intersection resonance array technology, intersection resonance ejection array technique, automatic resonance frequency tracker adjustment technology and method, belong to new-energy automobile field.
Background technology
According to the planning of State Council, to the year two thousand twenty, the accumulative sales volume of electric automobile will more than 5,000,000.The technology of current electric automobile has entered the extensive commercial maturity period.Along with electric automobile is commercial on a large scale, the charging problems of electric automobile will become increasingly conspicuous, and even become the throat of restriction electric automobile penetration and promotion.The charging method of electric automobile can be divided into wired static state charging substantially, wired mobile charging, and wireless static state charging and wireless mobile charge four kinds of charging modes.Wired mobile charging tramcar in early days, trolley bus are applied to some extent, and current subway and high ferro are all also adopt wired mobile charging or supply power mode.Wired static state charging is exactly so-called charging station and charging pile, just can solve electric automobile at the Line Contacts type charging pile of Large scale construction at present to charge in berthing, but because the charging interval is relatively long, general charging pile needs the battery of an electric automobile could be full of for 6-8 hour, in road, wait for that charging in 6-8 hour is difficult to allow most of car owner and passenger accept, therefore, even if itinerary built a lot of charging piles be also difficult to the problem that solution charges during the journey.Charging interval can be shortened to about 20 minutes by high-power quick charge stake, but the energy ezpenditure of quick charge will be tens times of common charging, will be not only that switch-time load impacts to electrical network, and waste energy.
Just achieved in laboratory before the wireless static charging technique more than ten years, closely noncontact wireless charging technology has been applied in the charger of telephone set, in the charger of various electric tool several years ago.Conventional technology mainly contains three kinds: one is magnetic coupling techniques, and the second is electromagentic resonance technology, and the third is microwave technology.Three kinds of technology respectively have pluses and minuses, and the distance of microwave technology transmitting energy is relatively far away, but powerful microwave has certain injury and efficiency also lower to human body, does not therefore just consider and is used in civilian use electric automotive field; The Energy Transfer distance of electromagentic resonance technology can reach tens centimetres, but through-put power does not have the large of magnetic coupling techniques relatively; Magnetic coupling techniques is relatively applicable to high-power energy transmission, but the environment used is all closely: the distance between charging reflector and receiver is all less than tens millimeters.Along with the development of New-energy electric vehicle technology, wireless charging is more and more higher in the demand in electric automobile field.Many people propose and existing electromagnetic coupled charging technique and electromagentic resonance charging technique are applied to electric automobile field.The Research Team of many universities and colleges and enterprises and institutions, comprise the domestic and international Research Team of the present inventor and cooperation thereof, all move in energy transmission technology at high-power wireless and done a large amount of research work, comprise the application of electromagnetic coupled charging technique and electromagentic resonance technology.
At electromagentic resonance technical elements, the disruptive technology that the research group of Massachusetts Institute Technology proposed in 2007, they use the helical coil of two radius 30cm in laboratory, Energy Transfer is carried out under the frequency of 9.9MHz, 2m of being separated by transmits 60W power, successfully lighted the bulb of a 60W, efficiency of transmission is 40%.Follow-up several Research Teams at home, by fine setting electromagentic resonance technology and optimum configurations, efficiency is made to obtain further raising, such as: Harbin Institute of Technology has carried out related experiment and scale-model investigation to electromagentic resonance formula wireless charging, achieve 50W power delivery, efficiency reaches 60%.South China Science & Engineering University has carried out follow-up study to electromagentic resonance formula wireless charging technology, achieves 50 centimetres of multikilowatt wireless power transfer, efficiency of transmission about 85% in laboratory.And these technology also all rest on wireless static charging aspect.The domestic and international Research Team of the present inventor and cooperation thereof has also carried out a large amount of comprehensively experimental study and test to electromagentic resonance formula wireless charging technology, first proposed " electromagnetism automatic focus " technology and " automatic focus of Electromagnetic Dynamic array " technology (number of patent application: 2014105594928,2014206066332,2014103885755) make wireless mobile rechargeable energy efficiency of transmission bring up to more than 90%.
In electromagnetic coupled charging technique, be just applied in the wireless charger of telephone set and electric tool before the electromagnetic coupled charging technique more than ten years, but be generally all small-power Energy Transfer.The Research Team of many enterprises and institutions, comprised the domestic and international Research Team of the present inventor and cooperation thereof in recent years, carried out having done large quantifier elimination in high-power charging electromagnetic coupled charging technique being applied to electric automobile field.Due to square being inversely proportional to of the charge efficiency of existing electromagnetic coupled charging technique and the distance between charging reflector and receiver, distance efficiency far away is lower, and the domain of electric automobile is general all between 200-500 millimeter far from the distance on road surface, therefore existing electromagnetic coupled charging technique is lower for the charge efficiency in electric automobile field.Also someone proposes and install a support that can adjust height for reducing the distance of reception antenna and road surface below automobile chassis, this method is carried out non-contact charge for parking lot and can also be accepted under electric automobile inactive state, but for the electric automobile in running at high speed, too reduce the distance on reception antenna and road surface, any jolting will cause serious potential safety hazard.Some researchers directly use air core coil transmitting energy, and when power output 2kW, transmission range 15 centimetres, system effectiveness is 82%; And be all for wireless static charging method." the magnetic conduction rubber " of the domestic and international Research Team proposition of the present inventor and cooperation thereof, " magnetic conduction rubber column array " technology, " the charging take-up coil array group of Heterogeneous Permutation " technology, and " chargeable magnetic conduction the tire " (number of patent application: 2014104028097 using these Technology design to make, 2014204622343) wireless charging receiving coil is made to have transferred to inside tire below the chassis of electric automobile, shorten the distance between transmitting coil and receiving coil and effectively raise electromagnetic coupled coefficient, the high-power wireless mobile charging energy transmission efficiency of electric automobile is made to bring up to more than 95%.
In sum, existing wireless charging technology major part is all based on static wireless charging method, is directly used in electric automobile wireless mobile charging field and will has certain loss in efficiency.The shortcoming and defect that existing wireless mobile charging technique exists comprises: 1, be only adapted to static wireless charging; 2, charge efficiency is relatively low; 3, certain high frequency loss is had.
