In recent years, China's low-speed electric vehicles have developed rapidly, with an average annual growth rate of more than 50%. Some people even hailed the low-speed electric car as the "fourth generation national car" in China. After bicycles, motorcycles and electric bicycles, low-speed electric vehicles gradually began to spread rapidly.
The sales and production value have increased sharply year after year, but on the eve of the spring of the industry, the "National Car" standard has been controversial, lead batteries or lithium batteries has become the focus of discussion.
The key question is what's the difference between lead acid battery and lithium ion battery?
In fact, lead storage batteries do not have safety problems. Lead batteries have been born for more than 160 years, and the technology is very mature. So far, no new technology can replaced it completely . Lithium batteries do have advantages in terms of energy density and cycle life.
The use of lithium batteries can make low-speed electric vehicles more lightweight, and the cruising range can be improved one after another, but the cost is an important factor restricting the development of the market. Both have their own advantages and disadvantages, no doubt the lead acid battery is in line with the current market development needs, while the lithium ion battery will gradually reduce the cost of replacing lead storage batteries with the increase of modularization, serialization level and total production capacity.
Low speed does not mean low quality. For example, the traditional enterprise represented by Dayang Qiaoke has begun to hire famous American car designers to carry out the operation.
It has a complete safety test system, and its product quality has reached European standards and is exported to Europe, America and Japan，Korea ect. It can be seen that low-speed electric vehicles are being promoted and revolutionized by the laws of the market. New technologies and new patents are gradually put into product design, and the industry is moving in a positive direction.
Lead-acid batteries meet the current consumption level, and improve the supervision system can effectively avoid pollution problems. Lithium batteries will follow the rapid development of the low-speed electric vehicle industry, and the process will change to a qualitative change. The cost reduction will promote the low-speed electric vehicle lithium-ion upgrade. In the process of formulating low-speed electric vehicle industry standards, we should also refer to the laws of the market and respect national interests rather than a “one size fits all” attitude.
