Changsha is one of the first demonstration and promotion cities for energy-saving and new-energy vehicles in China. Since the first batch of pure electric bus trial operation in 2011, the number of new energy buses has exceeded 5,000. According to the development plan, 2017 Changsha plans to add another 1,000 pure electric buses. By the end of 2020, new energy buses account for 100%, of which pure electric buses account for 50%. Like many large and medium-sized cities, in the process of rapidly promoting the application of new energy buses, Changsha has become a problem that restricts the development of new energy buses due to the scarcity of land resources in the urban areas. After extensive research, Changsha decided to try to use fast-filled pure electric buses to solve this problem.
Recently, Changsha Wanzhong Bus Company has purchased 100 fast-filled pure electric buses. The first batch of 12 buses were put into operation at the Changsha Dongsheng Road bus station. These vehicles also marked the first batch application of fast charge technology in Changsha bus. .
Different from the pure electric vehicles used before, the vehicles are equipped with micro-macro fast-charge batteries from Huzhou, which can be charged in 10-15 minutes, which improves the charging efficiency and reduces the number of charging piles for bus companies. Claim. It is reported that there are 576 new charging piles in Changsha in 2016. By the end of 2016, there were 903 charging piles put into operation in the city, and the problem of fewer piles was quite prominent.
According to Hu Gangwen, manager of the operation department of Changsha Wanzhong Bus Company, under normal circumstances, one slow-filling pile can meet the daily charging needs of two ordinary electric buses, while one fast-filling pile can charge up to 7-10. Bus charging. The Wanzhong Bus Company has built six 300kW fast-filling piles in the limited space of the Dongsheng Road bus station by self-raising, which can meet the charging needs of the large-scale vehicles after they are put into use.
In addition, pure electric buses equipped with micro-macro fast-charge batteries are very suitable for replenishing electricity at intervals, and are basically similar to traditional vehicles in line operation scheduling. Micro-macro fast-charge batteries also have high safety and long life. Characteristics, these advantages have been unanimously recognized by bus company drivers, dispatch management and crew, laying a good foundation for later promotion and application.
With the gradual improvement of the operation and dispatching plan and the use of other new stations and fast-filled piles, more fast-fill buses will be put into operation in Changsha, which will bring Changsha's city image and taste to a new level. It is of great significance to the development and promotion of new energy industry in Changsha and the development of public transportation service industry.
