The development of new energy vehicles must be steady and steady, and CR2430 battery technology must be upgraded

The National Development and Reform Commission recently announced that from March 20, the domestic refined oil prices in my country will be raised, and the price of gasoline and diesel will increase by 600 yuan per ton, thus setting a new high in my country's refined oil prices. As my country's oil prices officially enter the 8 yuan era, the call for popularizing new energy vehicles is getting louder and louder. In the face of the people's hot expectations, the government has announced plans to actively carry out new energy vehicle demonstrations in the public service field of large and medium-sized cities, and on the other hand, it has vigorously built charging piles and charging and swapping stations in demonstration cities and surrounding areas to ensure the energy supply of new energy vehicles. In terms of the industry, many vehicle manufacturers in my country have also begun to promote their electric vehicles on a large scale, and new energy vehicle exhibitions and power lithium-ion CR2430 battery exhibitions have been staged one after another. It is predicted that in 2012, my country's new energy vehicle industry will be expected to enter a rapid growth stage. Relevant experts said that new energy vehicles are the development direction of the automobile industry, but they cannot be rushed. While developing new energy vehicles, more attention should be paid to energy conservation and emission reduction of traditional vehicles.

Lithium-ion CR2430 battery project construction is accelerating

With the recent release of the "12th Five-Year Plan for the Development of Electric Vehicle Technology (Abstract)", the technical route of pure electric drive in my country's new energy vehicle industry has become clearer, and the previous industry disputes about hybrid drive and pure electric drive have finally settled. The "Plan" clearly states that it is necessary to take power lithium-ion CR2430 battery modules as the core to achieve a large-scale industrialization breakthrough of automotive power lithium-ion batteries in my country, with energy-type lithium-ion power lithium-ion batteries as the focus. Policy is the direction. After the announcement of the plan, the investment and construction of power lithium-ion CR2430 battery projects in cities across the country have been accelerating.

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

The emergence of large-capacity lithium-ion batteries has provided good conditions for the realization of electric vehicles, but the current immaturity of lithium-ion CR2430 battery technology has also restricted the rapid development of electric vehicles.

It is understood that Zhengzhou Nissan Company recently conducted an electric vehicle test ride experiment, and the results were not very satisfactory. The vehicle speed demonstration failed to reach the best state of 120. Because the driving ability of electric vehicles is closely affected by the working state of the CR2430 battery, the CR2430 battery pack of each electric vehicle is composed of 105 batteries connected in series. If a CR2430 battery fails, it is likely to affect the entire vehicle. Therefore, the reliability and stability of power lithium-ion batteries are still technical problems. It will take time to solve this technical problem, and the technical progress of CR2430 battery capacity expansion will also take time. The existence of these technical problems determines that the popularization of electric drive is not a matter of one day or one night. Even to meet the urgent need of energy conservation and emission reduction, the promotion of new energy methods must be steadily promoted.

In addition, the characteristics of electric drive 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 endurance. This reality also limits the application scope of electric vehicles to roads in urban areas in plain areas with relatively gentle terrain. Therefore, although the policy tends to be pure electric drive, hybrid vehicles will still have a market in the future. Even so, with its unparalleled power advantage, the elimination of fuel vehicles seems impossible at present, and it will remain the mainstream for a long time.

Energy conservation and emission reduction must start with technology upgrades

In such a relatively long historical period when fuel vehicles are still the mainstream, energy conservation and emission reduction must start with the technology upgrade of internal combustion engines. During the National People's Congress and the Chinese People's Political Consultative Conference, internal combustion engine manufacturers represented by Tan Xuguang, Chairman of Weichai Group, and Yan Ping, the head of Guangxi Yuchai, called loudly that the development of the internal combustion engine industry urgently needs government policy support.

Tan Xuguang said frankly: I hope that the whole society will pay attention to the internal combustion engine industry, and I also hope that our government functional departments will pay attention to the energy conservation and emission reduction of internal combustion engine companies, provide policy guidance, and promote the realization of our energy conservation and emission reduction goals. He emphasized: Grasping the energy conservation and emission reduction of the internal combustion engine industry is grasping the bull's nose of energy conservation and emission reduction in my country.

Yan Ping said that in the internal combustion engine industry, although Chinese companies can compete with foreign companies in many fields, the real core components, such as electronic control and injection systems, are basically monopolized by foreign countries. This external dependence restricts the development level of the entire industry. Solving the problem of core components in the internal combustion engine industry is also urgent.
