The car company of world each country has reached a consensus, car of new energy resources will be electric car sings leading role, and all new energy resources that we see now, for example raw material of diesel engine, biology, mixture motivation just transfers etc motivation. Passed controversy of ten years and exploration, motor-car of report of hydrogenous fuel cell has shown itself, also made the research way with each old car main manufacturer, and the successful case that the super capacitor that lays in one of means of energy as electric car had application in abroad and home, ever also made one of way of research and development with electric main vehicle.
11 buses of Shanghai are super electric capacity is economic change
2004 first Guangzhou car is exhibited on, honda revealed FCX of car of hydrogenous fuel cell. FCX power system uses system of cell of fuel of type of high-pressured pure hydrogen, because quantity of discharge of hydrogenous fuel cell is constant, because this cannot use it to carry acting n for electromotor directly, big n needs when be being quickened because of car, and glide, n does not need again when decelerate, must have then store electric equipment regards group of hydrogenous fuel cell as temporary memory n. On FCX, this store electric equipment is not traditional batteries group, use super capacitor however.
Another super capacitance car that causes world attention is practical the case that turn, it is the scientific research achievement of our country however, on 11 buses that are in Shanghai. 11 buses are a terminus and start station be in Shanghai old on the west the link line of the door is public transportation circuit, it is the used super capacitance bus exclusively now public transportation line on the world, and 11 operation time has had two years.
Inchoate investment runs bus of 11 super capacitance of Shanghai have 10 electric car, average specific power consumption is 0.98kWh/km, average energy recovers rate achieve 20% . That is to say, every kilometer uses up super capacitance bus only 1 degree of report, use cost wants than using the bus of internal-combustion engine far low. Similar such bus, will be in before world rich was met 2010, receive more wide application.
11 buses exterior connects traffic with general and differ without what, but it is OK to there is on roof control rises fall charge electric tool. Bus of this kind of super capacitance fills report, can travel 5 kilometers of 3 ―, then to solve super capacitance store n slants small issue, of 11 buses on the way a lot of stations provided equipment unit. Of super capacitance charge time is very fast, it jockeys in the bus the brief time of fluctuation guest, can fill report, satisfy the n requirement of next travel interval.
Why does the look have super capacitance and general electrify to differ?
Super capacitor (Supercapacitor) , call electric double layer capacitor again (capacitance of Electrical Doule-Layer Capacitor) , gold, farad capacitance. It and the biggest distinction that general electrify holds are the physical component that it is a kind of electrochemistry, but itself does not have chemical reaction, of super capacitance store n is particularly big, achieve the capacitance of farad class. Where is the area that how raises two plate? Super capacitance comes through infuse electrolyte store can, electrolyte falls in the action of electrode, electrode surface charge will be attracted all round the opposite sex in electrolyte solution is ionic, make these ion are added at electrode apparently form double charge layer, make capacitor of electric double layer. The space as a result of two charge layer is very little (general 0.5mm the following) , again together with uses special electrode structure, make electrode surface is accumulated of 10 thousand times increase, produce huge capacitance thereby.
