The battle for low-speed electric car power batteries

In recent years, China's low-speed electric vehicle development momentum is rapid, the average annual growth rate of more than 50 %. Some people even hailed low-speed electric vehicles as China's "fourth-generation national cars." After bicycles, motorcycles and electric bicycles, low-speed electric vehicles gradually began to become popular. The well-known brands such as Dayang Qiaoke and Redding have increased their production and sales year after year. However, on the eve of the spring of the industry, the formulation of the "national car" standard has been controversial, and lead batteries or lithium batteries have become the focus of current discussions.

Compared with traditional cars and "high-speed electric vehicles", "low-speed electric vehicles" are slow to drive, small in size, and lightweight. They have many advantages such as low cost, energy conservation, and flexibility. They are powerful vehicles for short distances. Some data show that the market for low-speed electric vehicles has reached 4 million vehicles in 2016. Therefore, some experts are concerned that lead batteries will continue to be used as a power source. When a large number of batteries are eliminated, lead pollution will be easily caused during recycling and smelting., not only harm human health, It can also cause environmental pollution.

Lead battery pollution is a "false proposition"

So, the key question is what is the difference between a lead battery and a lithium battery? In fact, there is no safety problem in lead batteries. Lead batteries have been born for more than 160 years. The technology is very mature. So far, no new technology has been completely replaced. Lithium batteries do have advantages in energy density and cycle life. The use of lithium batteries can make low-speed electric vehicles more lightweight and mileage can be increased one after another. However, cost is an important factor that restricts the development of the market. Both have their own advantages and disadvantages. The former undoubtedly meets the current market development needs, while the latter will be accompanied by modularization, increased serialization levels and increased total production capacity, gradually reducing costs instead of lead batteries.

In the end, the controversy is focused on the pollution risk of lead batteries, but some industry insiders believe that "the problem is not pollution, but how to regulate it. "Today, the recycling technology of lead batteries has become very mature. Take Tianeng Group as an example, the annual processing capacity has reached 300,000 tons per year. In foreign countries, the disposal of lead batteries does not belong to the pollution industry. This is not a technical problem, but it is a regulatory problem. Some people in the industry even questioned the traditional automotive industry: "In 2016, China's traditional car sales exceeded 28 million vehicles, that is, 28 million lead batteries were used. Why does no one suspect that the traditional car industry is polluting the environment? "

Low speed electric car quality is also reliable

For ordinary consumers, low-speed electric vehicles are equivalent to "elderly walkers", with poor quality, rough manufacturing, and cheap goods. Undeniably, in the early development of the industry, from the design of work to brand strength, there are indeed many problems. At the moment, many powerful companies have begun to intervene in the industry, including Internet companies represented by Le, and traditional manufacturing companies represented by Dayang. The rapid development of the low-speed electric vehicle industry brings rapid iterative upgrading and research and development of innovative technology patents.

Low speed does not represent low quality. For example, the traditional companies represented by Dayang Qiaoke have begun to hire famous American car designers to perform knives, have a complete safety test system, and the product quality has reached European standards, and is exported to Europe, the United States, Japan and South Korea. Developed regions, Patent technology has more than a hundred items. It can be seen that low-speed electric vehicles are being promoted by the laws of the market, self-innovation and revolution, new technologies and new patents are gradually put into product design, and the industry is moving in a positive direction.

Lead batteries meet the current consumption level and improve the regulatory system can effectively avoid pollution problems. Lithium-ion batteries will follow the rapid development of the low-speed electric vehicle industry, and the process of quantitative change to qualitative change will continue to reduce the cost of low-speed electric vehicles. Lithium-electric upgrade. In the process of setting the standard of low-speed electric vehicle industry, we should also refer to the laws of the market and respect the interests of the people, rather than the "one size fits all" attitude.
