Expo this year, the practice of new energy laptop battery bus zone Expo fairly obvious over 150 new energy vehicles, with buses running, no nasty petrol fumes, but there is no noise, so that visitors were very happy. Is this the future development of the transportation experience in low carbon economy.
bus low carbon “very refreshing” laptop battery
Shanghai Bus (Group) Co., Ltd. Hung Jen-president and general manager, said the start of Expo underway, the bus center in the nation to low-carbon most advanced, is the last of achievements in the development of new energy vehicles presentation concentrated.
The Expo will have over 1,000 new energy vehicles in the scene of the World Expo in and around the race, is the most important event in the world of new energy vehicles running, including 120 bus capacity pure 36 passengers and six super capacitor hydrogen buses.
Hung Jen-first, as expected, train and bus 4 percent of all passengers bear park, take the ferry in two. But statistics show that more than half the journey Expo, buses take more than 75% of traffic: “The results have exceeded expectations.”
City bus line system operations were over 16,000 units of vehicles, the average daily flow of travelers from more than 700 million euros, while Expo bus low-carbon, the maximum commitment of time about 900,000 passengers. Hung Jen-first said: “Expo Area 1% of vehicles with the city, take the tenth of a passenger.”
Liu entered the public visited the Expo 10 times, mostly in the park, take the bus. He said, take public transportation to low-carbon public feeling “fresh.” “There is no pollution, noise is minimal.”
Expect revolution in battery technology
■ EXPO electric buses, each with advantages and disadvantages
Although the super capacitor charge faster bus, but the reserves are small, and charging 25% of its energy into heat energy, causing energy waste. Hong Ren said the beginning of the current use of point of view, the relatively low cost super capacitor.
Expo Boulevard line with the car super capacitor, before the passengers in the bus 11 on the highway operations, capacity through technology upgrades continues the extension of 4 km, the original of each station must be raised by a “pigtail” free 1 minute, now Station Road, then two or three on a single charge.
Pure capacity buses, large reserves, but charge a long time, unable to meet the needs of continuous operation.
■ The canalization of the river, national development using the bus pure capacity
When the battery to reach the minimum deposit, the pilot pulls the price of the room charge. A total of 120 charging stations equipped with battery backup group can be transferred in time, just answer the request. charging time of battery is more than two hours, after adequate travel about 80 km.
Hung Jen-first said: “Both technologies still need to improve and we look forward to a revolution of the battery.” EXPO low carbon buses for the future of low carbon public transport, provision of technical support and data. low carbon future, buses will increase the quality and reliability. “But the development of new energy bus takes time. Originally upgraded to diesel fuel, used for 10 years. However, upgrading of new energy, it will take time.”
He also said that the recent development of low carbon direction of public transport are hybrids. The benefits are increased fuel efficiency, the relative effect of the environment is good. For example, the launch will not be “black smoke”, idling time and reduce oil consumption.
