Development of Electric Vehicles Cannot Abandon Functional Requirements

It is understood that from January 10 to January 14, 2013, the 2012 Global New Energy Vehicle Conference (GNEV2012) will be held in Boao, Hainan, China. The conference will discuss "micro-electric vehicles". What should be the development of micro-electric vehicles?

In cities such as Shandong, Jiangsu, and Zhejiang, in the second- and third-tier cities and in the urban-rural areas, a small-size, low-profile, micro-electric vehicle using lead-acid batteries has emerged quietly because of low acquisition costs and operating costs. It can satisfy some of the travel needs and is popular with consumers. It has formed a certain market scale and is showing rapid development. What are the concepts and standards of “mini electric vehicles” acceptable to consumers, who will buy them, what are their purchase purposes and preferences, and what technological innovations will companies need to make to improve consumer satisfaction?

The first electric network invites people from all walks of life to discuss the topic of “How can I love you?” and looks forward to sharing the best views and consensus with more netizens.

“At present, many low-speed electric vehicles are built on a low-level basis, which can only solve temporary needs, but they cannot solve long-term problems and therefore cannot win the trust of the people. We must develop electric vehicles to meet the growing needs of consumers. Instead of reducing their existing car use levels." Shi Hengkuan, vice chairman of the China High-tech Industrialization Research Association, said.

Ji Hengkuan believes that the current car purchased by consumers is generally aesthetically pleasing, driving and riding comfortably, and less likely to be anchored. The development of electric vehicles should also meet these conditions and achieve certain performance parameters, otherwise they will be complained by consumers.

In Ji Hengkuan's view, the maximum speed and driving range of 100 kilometers are the basic requirements for electric vehicles, and the current low-speed electric vehicles obviously cannot meet these parameters. This point of view coincides with the “appropriate parameters” of electric vehicles proposed by Wang Binggang, head of the supervision consulting expert group of the National 863 “Energy-saving and New Energy Vehicle” major project.

However, Ji Hengkuan frankly stated that even if it is a "basic requirement" of 100 kilometers, many non-low-speed electric car companies cannot achieve it. The key reason is that the bottleneck of battery technology is difficult to break through. Therefore, he hopes that the state will increase investment, strengthen battery R&D and technology transformation, and promote the rapid development of the electric vehicle industry.

In addition, Ji Hengkuan pointed out that low-speed electric vehicles are not conducive to improving people’s living standards, and there are also great potential safety risks. Talking about his experience of riding a low-speed electric car in a suburb of the city, he was deeply impressed. “The suburbs can't hit a taxi. Only a low-speed electric car can be chosen. The car I'm sitting on has no license plate and runs parallel with other cars in the fast lane. It makes people scared."

It is worth mentioning that another expert in the field of power batteries expressed their different views on the “safety issues” of low-speed electric vehicles when they were interviewed by Ji Hengkuan.

The expert told the reporter that since the electrolyte of the lead-acid battery is an aqueous solution, there is no smoke or ignition problem. Therefore, the lead-acid battery itself has a very good safety performance. If the speed is controlled, an electric vehicle equipped with a lead-acid battery is not available. Too much safety problem. However, he also pointed out that given the low speed of low-speed electric vehicles, the driving range is too short, and it is only suitable for appropriate sales in some rural areas.

In fact, although many experts including Ji Hengkuan did not favor the development of low-speed electric vehicles, in recent years, low-speed electric vehicles have achieved rapid development in Shandong and other places with great price advantages and convenience. According to information released by the Shandong Economic and Information Commission, in the first half of this year, local sales of low-speed electric vehicles in Shandong reached 44,000, an increase of 74.8% year-on-year, which is a “record” of other electric vehicles.

At the same time, the media has recently revealed that low-speed electric vehicles will obtain the Ministry of Industry and Information Technology's new energy vehicle production qualifications, saying that low-speed electric cars or renamed 'short-haul pure electric passenger cars', once suffered from low-speed electric vehicles away from the "positive" It seems to be close at hand.

For this news, Ji Hengkuan said it was unclear, but he pointed out that even if low-speed electric vehicles may “turn positive”, they must meet certain standards, and maintaining the current level of low-speed electric vehicles cannot obtain national recognition, and it is impossible to guarantee the basic interests of ordinary people. And the use of the car.
