On August 28th, 2006, the Shanghai Science and Technology Innovation Mountaineering Action Plan Demonstration Line 1 1, which was participated by Aowei Technology and other units, was officially opened, marking the pace of commercial operation of the first supercapacitor electric bus line in China and even the world. These 10 "zero pollution" supercapacitor buses and 10 intelligent charging stations look like trolleybuses, but the difference is that two big "pigtails" are cut off from the top of the car and a supercapacitor is installed under the car. After the car enters the station, using the gap between the upper and lower passengers, the roof charging equipment will automatically rise vertically, ride on the cable hidden under the "eaves" of the waiting station, and complete charging in 30 seconds, which can run smoothly for 3-8 kilometers and the top speed can reach 44 kilometers per hour. Compared with trams and trolleybuses, supercapacitor buses have no ground track and overhead catenary, which is conducive to "purifying" urban space. It is understood that when the air conditioner is turned on, the energy consumption per kilometer of the air-conditioned supercapacitor bus is only 1.4kWh, the energy consumption cost is only 33% of that of the fuel vehicle, and the energy recovery rate reaches 40% when braking. Although the technology of this kind of car is not perfect, the driver's control is not in place, and there will be some minor problems, but its running prospect is beyond doubt.
The typical driving structure of an electric vehicle is shown in the figure.
In addition, supercapacitors are used in power distribution stations, tax controllers, tax-controlled cash registers, and DC systems that shake flashlights (you don't need to replace batteries, you can light them for 5 minutes only by shaking them for 30 seconds; The irradiation distance is 1 m), smart meters (such as smart water meters and gas meters) and computer UPS power supplies are also widely used. You can find several shops selling this new type of power supply by opening Taobao, which is enough to show its marketization. Some experts predict that one day, the technology of electric double layer capacitor will become mature, the cost will be accepted by people, and the streets will be full of electric vehicles!
