If you want to ask, where does China’s new energy vehicles started? The answer is probably more than 10m city bus electric bus. Because this is apparently the solution of pure electric vehicles is the simplest. Of course, the extended-range does not rule out future possibilities bus. But hybrid technology is clearly the most complex models and lower government subsidies.
And in terms of electric passenger cars, because the main consumer target is private, so the price is the primary constraint, followed by charging infrastructure, again more or reliability, maintenance costs and so on. These factors for the public services of the city bus was weaker.
In the “city of one thousand ten” model notice under the impetus of the pilot, the current 25 model city has been under way. Who do not want to work in the environmental performance image of the city lost the competition. In 2012, to complete the project if its electric city buses should reach 25,000. Net of the past two years has completed 5,000 units, it takes at least 20,000. If the battery power is 160kWh per vehicle basis, the total energy needs 3.2 million kWh, then the 2011 and 2012 the demand for each of its battery power for the 1.6 million kWh. And this figure is not only high-low comparisons with each other is the “Chinese characteristics.”
The moment, though customary, such as “herd” was heard, but in terms of production capacity, is still a gap. At present, lithium-ion batteries have been built production capacity of about 300 million Ah, equivalent to 9,600,000 Wh. Consistency of these products assume all the standards, can only assemble 19,200 more than 10m city bus. However, each enterprise in the factory before, must produce their products quality and consistency, and security testing, the exclusion of “short-board effect” and other defects, the passing rate of its products only about 70% or so. And these products can also include a significant proportion of export and domestic passenger facilities, and power grid energy storage, industrial and other large markets outside the automotive industry. It seems that despite the lithium-ion battery production line successor to a lot of people, but the outlook remains optimistic.
Recently, the editorial board of nearly 10 in the Pearl River Delta to conduct research when the battery business, pleasantly surprised to find each company’s product line has emerged as the scene in full swing. Worth Fortunately, each company’s senior leadership see themselves described as the country’s best products, reflecting confidently optimistic picture. More valuable is that most business leaders believe that their products and that there is such a problem, there is room for further improvement. For example, on the battery positive and negative materials, structure, and process improvement, weight and volume in the same case, the energy increased by 60%. Corporate commitment and even the price per Ah battery, a year from now reduced by 1 million.
At the national policy to promote energy saving and battery efforts of their own greatness, the Chinese city buses will eventually be out of the “city of one thousand ten” framework, there will be 2012 new blueprint.
