Development of New Energy Vehicles -Lithium - Ion Battery Equipment

As my country's oil price officially enters the era of 8 yuan, the voice of popularizing new energy vehicles is getting louder and louder. Faced with the people's high expectations, the government announced plans to actively carry out new energy vehicle demonstrations in the public service areas of large and medium-sized cities. energy supply. In terms of industry, many Chinese vehicle manufacturing companies have also begun to promote their electric vehicles, and new energy auto exhibitions and power lithium-ion battery exhibitions have been staged one after another. Relevant experts said that new energy vehicles are the development direction of the automobile industry, but there is no rush. While developing new energy vehicles, more attention should be paid to the energy saving and emission reduction of traditional vehicles.

Lithium-ion battery project construction accelerated

With the publication of the "Twelfth Five-Year Special Plan for the Development of Electric Vehicle Science and Technology (Summary)", the technical route of pure electric drive in my country's new energy vehicle industry has become more clear, and the industry's previous disputes about hybrid drive and pure electric drive have finally been settled. The "Plan" clearly states that it is necessary to focus on the power lithium-ion battery module to achieve a breakthrough in the large-scale industrialization of the energy-type lithium-ion power lithium-ion battery for vehicles in my country. Policy is the direction. After the announcement of the plan, the investment and construction of power lithium-ion battery projects in cities across the country are accelerating day by day.(Lithium - Ion Battery Equipment)

The stability of power lithium-ion batteries still needs to be solved

The emergence of large-capacity lithium-ion batteries provides good conditions for the realization of electric vehicles, but the current immaturity of lithium-ion battery technology also limits the rapid development of electric vehicles.

It is understood that Zhengzhou Nissan recently conducted an electric vehicle test ride experiment, but the results were not very satisfactory, and the vehicle speed demonstration failed to reach the best 120 state. Because the driving ability of an electric vehicle is closely affected by the working state of the battery, the battery pack of each electric vehicle is composed of 105 batteries connected in series, and a failure of one battery is likely to affect the entire vehicle. Therefore, the reliability of the power lithium-ion battery Performance and stability are still technical problems. It will take time to solve this technical problem, and it will also take time for technical progress in battery capacity expansion. The existence of these technical problems determines that the popularization of electric drives will not happen overnight. Even in order to understand the urgent need for energy saving and emission reduction, the promotion of new energy methods must be promoted smoothly.

In addition, the electric drive characteristics of electric vehicles also limit their power performance, so there is a particularly obvious gap between electric vehicles and fuel vehicles in terms of speed, climbing ability and power durability. This reality also limits the application range of electric vehicles to On the roads in urban areas in plain areas with relatively gentle undulating terrain. Therefore, although the policy is inclined to pure electric drive, there is still a market for hybrid vehicles in the future. Even so, with its unparalleled power advantages, it seems impossible to eliminate fuel vehicles at present, and it will still be the mainstream for a long time.

Energy saving and emission reduction must start from technological upgrading

In such a relatively long historical period when fuel vehicles still exist as the mainstream, in order to save energy and reduce emissions, we must start with the technical upgrading of internal combustion engines. During the National Two Sessions, internal combustion engine manufacturers, represented by Chairman Tan Xuguang of Weichai Group and Yan Ping, head of Guangxi Yuchai, clamored loudly that the development of the internal combustion engine industry urgently needs government policy support.

Tan Xuguang said bluntly: I hope that the whole society will pay attention to the internal combustion engine industry, and we also hope that our government functional departments will care about the energy conservation and emission reduction of internal combustion engine companies, give policy guidance, and promote the realization of our energy conservation and emission reduction goals. He emphasized: Grasping the energy saving and emission reduction of the internal combustion engine industry is the key to my country's energy saving and emission reduction.
