Developing 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, Zhejiang, and other provinces and cities and rural areas, a small-size, low-profile, micro-electric vehicle using a lead-acid power battery has emerged quietly due to 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 purchasing 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 with mini-electric vehicles?” and we look forward to sharing wonderful 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 thus cannot obtain 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." According to Ji Hengkuo, vice chairman of China High-tech Industrialization Research Association.

Ji Hengkuan believes that the current car purchased by consumers is generally aesthetically pleasing, driving, and comfortable to ride, and it is less likely that anchoring will occur. 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 the electric vehicle 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 vehicle 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 and can only choose a low-speed electric car. 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 reporters that since the electrolyte of lead-acid batteries is an aqueous solution of sulfuric acid, there are no smoke and fire problems. Therefore, the safety of lead-acid batteries is very good. If the speed is controlled, electric vehicles equipped with lead-acid batteries are not too Great security issues. 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 vehicles 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 cannot guarantee the basic interests of ordinary people. And the use of the car.
