The two sessions focused on the field of new energy public transportation, and accelerated the advancement of lithium battery fast charging pilots

　　Li Xiangbin also found in the investigation that cities such as Ningbo and Hangzhou have already experimented with fast charging of lithium batteries. Vehicles can quickly charge while waiting for passengers to get on and off the bus, and can run seven or eight kilometers longer. "The fast charging mode of lithium batteries is still in the development stage. I hope the country can increase investment and speed up research and development."

　　It is reported that during this year's "Two Sessions", Li Xiangbin, a public transportation "old acquaintance" who was re-elected as a representative, focused his attention on the field of new energy public transportation. As an important position for new energy vehicles in the country, public transportation has always been a signboard, "but there are still shortcomings in battery life, and the country should speed up research and development."

　　The new energy electric bus started early. As early as January 23, 2010, the Public Transport Group opened 18 bus lines, which consisted of 30 pure electric vehicles and became the world's first pure electric vehicle bus line. However, Li Xiangbin, who works on the front line, also admitted that years of operations have also exposed some shortcomings. The most troublesome is the battery life of the bus.

　　The large size of the battery, the slow charging, and the small amount of stored power have restricted the rapid development of new energy buses. "For example, one of our buses needs to operate 300 kilometers per day, but the current battery life of new energy electric buses is about 250 kilometers. In case of traffic jams, it may only run 200 kilometers. A line requires two vehicles to complete. Increased operating costs.” He suggested that we should summarize development experience at the national level, organize several key enterprises, concentrate capital investment, and concentrate superior talents for research and development. Intensified research and development efforts on the traction motors and frequency converters of pure electric vehicles, and developed motor equipment with low power consumption and high traction, as well as power-saving and more efficient transmissions, so as to increase the battery's cruising range.
