Low-speed electric cars and lithium-ion batteries match the best

Recently, Dong Yang, executive vice President of China association of automobile manufacturers, published the article "Reflections on the Standard of Four-wheel Low-speed Electric Vehicle" (hereinafter referred to "Low-speed Electric Vehicle"). He said he was appointed to be the head of the standard drafting group by the equipment department of the ministry of industry and information technology, and made it clear that low-speed electric vehicles would not be allowed to use lead-acid batteries for safety reasons. This is consistent with the policy trend of the "Technical Conditions for Four-wheel Low-speed Electric Vehicle" national standard (hereinafter referred to the "National Standard") when the project was officially launched last October, the power battery equipped with low-speed electric vehicle should be upgraded from lead-acid battery to lithium-ion battery.

Definition and management of electric vehicles at low speed itself is complicated and intricate work, especially now the issue of regulating power batteries is back in the spotlight. It is conceivable that the formulation of future national standards will play a decisive role in the development of low-speed electric vehicles and power battery market.

National recognition of low speed lithium electric motor is the "right way"

Low-speed electric car industry is finally going to the national standard.

Low-speed electric cars in China produced more than millions of vehicles, and growth are over 50%, although there is no support from the policy, but its depend entirely on the market need to be developed. Therefore, industry sources said, low-speed electric cars as "brutal forces". At present about 95% of low-speed electric vehicles use lead-acid batteries, which have the characteristics of good abuse resistance, simple battery control system and layout requirements, low cost and so on. But with the large-scale application of lead-acid batteries, the production and recycling process of lead smoke and lead dust and pollutants such as wastewater containing lead, has caused great harm to the environment, at the same time for the production and living of people also brings some adverse effects.

At present, the national key support for new energy vehicles is given priority to with lithium batteries, and increasingly become the mainstream direction. According to reporter understanding, the development of China's new energy bus situation is good, most of the adopted lithium iron phosphate batteries, its security is good, relatively high energy density, the volume is relatively small. The battery enterprises in our country the basic mastered the core technology of lithium iron phosphate, but manganese acid lithium and ternary lithium battery technology is still control by the Japanese and south Korean companies. In the policy support and market demand under the background of gradually expanding, in recent years, lithium battery enterprises have sprung up.

In 2015, the ministry of industry and information technology, national development and reform commission, ministry of science and technology, ministry of public security, ministry of transport to the state council has reported on the low speed on the management of electric vehicles of instruct ", put forward "upgrade a batch, standardize a batch of elimination, a batch of" working train of thought, the department of state has instructions to agree. In April 2016, the national standard project plan to solicit opinions from the public, on November 18, the same year the first meeting was held in Beijing. It was at this meeting, low-speed electric cars are not allowed to use lead-acid batteries view is the first official mention.

The market has a soft spot for lead-acid batteries

Dong Yang said in the article, "the government management department's disagreement, (do not allow the low-speed electric cars use lead-acid batteries) most of the opposition". The reporter also discovers in interview, the voice that opposes inside and outside industry is not little really.

Yusheng. Yang, a member of the Chinese academy of engineering, is the most prominent. He pointed out that the national standard should not limit battery varieties, and each battery has advantages and disadvantages, which should be chosen by the market.

"The lithium-ion battery and no major breakthrough, also not solve the key pain points, otherwise wouldn't be so challenging to spreading new energy cars."Chinese battery industry association vice President of original Jingzhong, Wang told reporters, for lithium battery technology further mature and improve the performance and cost have fallen sharply, more cost-effective compared with lead-acid batteries, the audience will naturally choose lithium battery.

The reporter interviewed the Shandong wind (group) co., LTD. Relevant personage, and they produce products including low-speed electric cars. The enterprise according to the current the low-speed electric cars have equipped with lead-acid batteries, and use of lithium-ion batteries, but the market acceptance of the former is higher.

In addition, according to the reporter, Avic lithium battery and other lithium battery enterprises have also opened up the market of low-speed electric vehicles, but later chose to give up because the effect is not good. Jingzhong. Wang thinks, lithium battery is in at present field of low speed electric vehicle popularize very hard wide range, and will make cycle cost increases 10 thousand yuan.

On the issue of whether lead-acid batteries should be allowed, Mr. Dong argues that too much attention is likely to drag on. The implication is that, from the perspective of environmental protection and the long-term development of the new energy automobile industry, it should be cut off.

Lithium battery market may ignite new vitality

"If a million low-speed electric cars a year all use lithium batteries, it will obviously bring a huge market space to the industry." Henan Huanyusai new energy technology co., LTD. Executive vice President Han Guangxin told reporters.

According to the government department "upgrade a batch, standardize a batch, eliminate a batch" working ideas, Han Guangxin speculate that the future enterprise production low-speed electric cars need to apply for qualification, the driver vehicle license and driving license shall be on the road, traffic is subject to the registration and pay the insurance."So, the quality and performance of the low speed electric vehicles must further improve, because of its flexible and convenient, and is lower than traditional gasoline vehicles and new energy automobile price, It is likely to squeeze 20% of the private car market."He said.

It is understood that the lithium battery manufacturers such as Sinergy and Huanyuserl, and even the enterprises in the field of battery management system, have some expectations for this emerging market, and some are even on the way. "If the timing is right and the market needs to be strong, we will enter the market again," Ruan Yiliang, head of the lithium power market department at Avic, told reporters.

At present, the outside world to the lithium battery can be "qualified" low-speed electric car market is worried about is, the cost, safety, recovery and the problems of the vehicle allocation, still needs further investigation. In the long run, though, the price of lithium-ion batteries will surely fall, no doubt about it.

Han Guangxin tells the reporter that Lithium-ion battery enterprises are actively developing new platforms that are suitable for low-speed electric vehicles and actively looking for battery combinations with advantages of cost and energy density ratio. Chinese companies are also actively studying battery management systems, such as managing each battery chip to further improve the safety of lithium-ion batteries, he said.
