Description
Technical field
The present invention relates to a kind of power coordination control type fuel cell charging pile, particularly one utilizes high temperature solid oxide fuel cell to realize charging electric vehicle, belongs to technical field of new energies.
Background technology
Chinese automobile volume of production and marketing is the most fast-developing, and Ministry of Industry and Information issues annual auto industry Economic Operation in 2014.Data show, China in 2014 is accumulative produces 2372.29 ten thousand, automobile, increase by 7.3% on a year-on-year basis, and selling automobiles 2349.19 ten thousand increases by 6.9% on a year-on-year basis, and volume of production and marketing keeps the first in the world.Automobile has become as indispensable important component part in our daily life, the increase of automobile, brings serious pollution, the most most importantly the tail gas severe contamination air of motor vehicle emission to my living environment.Effective solution is development new-energy automobile, and on the one hand new-energy automobile can solve oil crisis problem, on the other hand solves car exhaust gas environmental pollution problem.
The new-energy automobile new model of money more than totally 300 listing in 2014, produces 8.39 ten thousand, increases by nearly 4 times on a year-on-year basis.Wherein December produces 2.72 ten thousand, creates whole world new-energy automobile list monthly output highest record.Wherein, electric automobile is the main force of new-energy automobile, but the Pinch technology run in Development of Electric Vehicles is exactly battery technology.When battery technology does not obtain breaking through, by rapid nitriding to electric vehicle rapid charging, but rapid nitriding needs high-power, it is generally required to the electric energy of more than 50KW, even 100KW, the biggest charge power is equivalent to the electricity consumption of a large-scale office building.In general community or common place, quick charge stake cannot be installed.
Execute Traubel to say in this way in the Dialogue An Interview of MIT: I thinks that we can shorten to 5-10 minute the time.He mentions, and " current super charging station, using the teaching of the invention it is possible to provide 120 KW power, this is the most inconceivable before 10 years.Conventional public charging station can only provide 10 KW power below ".By super charging technique, tesla has led and bounds ahead of rival.Such as, current most popular rich power technology standard based on electric motor car charging association of Japan is quickly filled, using the teaching of the invention it is possible to provide 50KW charge power.SAE's brand-new quick charge standard that even if last October just decides on a verdict, just used by the Main Auto manufacturer such as general, 100KW power the most also can only be provided.One of difficult problem of quick charge is: quickly battery can be caused overheated to battery transmission of electricity.For avoiding damaging battery, external charger needs and the electronic equipment communication of detection battery status (including voltage and temperature), and the most quickly adjusts charging rate." in order to realize such charging modes, all must be well-designed, reaches perfect synchronization." execute Traubel and say.
One electric automobile needs the power of nearly 100KW when quick charge, and along with electric automobile constantly increases, 10,000 electric automobile quick charges simultaneously, the impact to electrical network is the most fearful, 1,000,000 amount electric automobiles？This may is that electrical network does not has a major reason of Large scale construction charging pile.
