Description
Technical field
The present invention relates to the field of renewable energy resource utilization of auto manufacturing, particularly a kind of internal combustion engine drive that changes is the plurality of voltages adjuster that is used for solar energy PV excitation alternating current generator that solar energy PV excitation is relied on oneself and driven.
Background technology
Since Energy Situation, and serious environmental is polluted day by day, and relevant bodies of the United Nations and national governments progressively strengthened the environment management in recent years, were also strengthening the input on the renewable energy utilization on the policy with on human and material resources, the financial resources simultaneously.Internal combustion engine has reached the limit of performance boost in its 100 years of development course.The engine performance of driver's expectation now and efficient adopt any other substitute technology all to be difficult to realize.But internal combustion engine is doomed and will be substituted under the pressure of environmental protection pressure, and limited still more traditional fuel resource will further promote this process.It is reported that it is the power car or the novel hybrid car of power that annual car exhibition all over the world all can occur with solar energy.
These type regenerative resource cars respectively have pluses and minuses, and the advantage of the driving car of solar cell is can not consider the continuation of the journey problem, environment is not had any pollution.But needing overcast and rainy or night other power source, multiple conversion efficiency of solar cell lower, is the bottleneck that the restriction car is already used.
Reason in sum: though constantly interview of electric motor car, in various degree have a following problems: the charging interval is long, continuation mileages for one time charging is shorter, such car existence continue problem and charging interval problem; It is bigger that solar energy directly drives the shared spatial area of vehicle, is unsuitable for using in relatively more crowded city; Specific energy is low, useful life is short; Problems such as cost cost height and safety enforcement.Cause electric motor car slowly to be difficult to invest market.
The other deficiency of solar power car is: the multiple conversion efficiency of solar cell that need other power source overcast and rainy or night, has emerged is lower, is the bottleneck that the restriction car is already used.
Developed fuel cell-powered car in order to solve the many enterprises of above deficiency.For example: on the automobile Da Zhan of Tokyo, put on display the Daimler Chris and rein in the F500 Mind type fuel combination power sample car of company.The Fine-N that Toyota Company puts on display is an other concept car, and this car adopts fuel cell to be used as power, and Applied Biotechnology discerns human pilot, can start the engine automatically after affirmation.The outstanding behaviours of this car is that its driving range has reached 500km(by 10/15 pattern).The lifting of driving range is because the improvement of following two aspects.The first, improved the supply structure of motor and fuel and air, the electric energy output that makes the water of Unit Weight provide is improved.The second, improved the pressure of high pressure hydrogen storage tank.The highest present the blowing pressure is 70MPa, approximately is the twice of former 35Mpa.Though the said firm is reduced to 3 bottles with the sum of the storage tank that carries by 4 bottles, still makes total storage volume improve 10～20%.
Such design is to have improved driving range, has increased total storage volume 10～20%, and the highest present the blowing pressure is 70MPa, approximately is the twice of former 35Mpa.So it has also reduced safe enforcement coefficient, each dolly with the air-pot of 3,4 nearly 700kg pressure, is the several times of black blasting powder in case its destructive power of accident is arranged all.
The rely on oneself power producer of city car of solar energy PV of the present invention is that solar energy PV excitation exchanges from power generator.The excitation of generator can derive from solar energy, that is to say that solar energy PV conversion exciting current is a primary energy of the present invention.Secondary energy sources through exchanging from power generator conversion output are the power of this car.There are not safety problems such as specific energy, charging interval, continuation of the journey mileage, the area that takes up space, high-voltage power supply.So it is longer than internal combustion engine useful life that the cost cost is lower than internal combustion engine, dragging system does not have a large amount of mechanical wear.
