Lead-acid batteries may be a thing of the past

Lead-acid batteries may be a thing of the past.

A few days ago, a media exposure "four-wheel low-speed electric vehicle - technical conditions (draft)" (hereinafter referred to as the draft), which provisions mean lithium battery will usher in greater market opportunities.

The draft eliminates lead-acid batteries and boosts lithium batteries

On the one hand, it is required that the power batteries used should meet the national standards for high-speed electric vehicles in terms of service life and safety, and the single battery capacity should not be less than 70Wh/kg. On the other hand, the draft explicitly mentions that lithium batteries should be used for power batteries of four-wheel low-speed electric vehicles, and they should be equipped with supporting battery packs and battery management systems.

The draft's signal is clear: the lead-acid batteries currently used in four-wheel low-speed electric cars will be replaced by lithium batteries.

Two voices, each with its own voice

For the "draft" provisions, in the industry is also caused by hot debate, two camps each.

Supporters camp said that the "draft" for the use of low-speed electric vehicle power battery products has played a very good role in the specification, is conducive to the low-speed electric vehicle chaos regulation; (2) more importantly, lithium battery energy density is higher, cycle life is more, and lead-acid battery not only large size, weight, and cycle life is also short, abandon lead-acid battery, lithium battery, is the trend; (3) lead acid battery production and recycling will have a serious impact on the environment. Although there are part of the lead-acid battery enterprise can realize the recovery and utilization of waste battery is effective, but it is understood that round of low-speed electric gb eventually clear negative allows the use of lead-acid battery, not only at present domestic lead-acid battery recycling management is uneven, soil lead pollution, children's blood lead paint phenomenon is very serious, and individual companies recycling is better than a few cases, and therefore can only according to the national condition to make uniform.

Opponents of the camp said that the cost of lead-acid battery is only a quarter of lithium battery. Take the battery as an example, if the battery capacity of each car is 10kWh, the price of lead-acid battery is 5,800 Yuan, while the price of lithium battery is 22,000 Yuan. It can be seen that after changing the battery type of low-speed electric vehicle, the price of single vehicle will greatly increase, and the final cost will be transferred to consumers, who will pay the bill. (2) some industry insiders questioned the interest groups by the "draft" of the standardization of lead-acid battery kill the survival of enterprises.

According to media sources, dong Yang, head of the national standard drafting group for low-speed electric vehicles and executive vice President of the China association of automobile manufacturers, revealed that the content of the draft is true, and the formal technical standards for four-wheel low-speed electric vehicles (draft for comments) will be issued soon.

In addition, fu yuwu, President of the Chinese society of automotive engineering, revealed that recently the ministry of industry and information technology once again organized a low-speed electric vehicle calibration symposium, a more in-depth discussion of low-speed electric vehicle standards related issues.

It can be seen that the formulation and introduction of relevant standards for low-speed electric vehicles has become a forgone conclusion. Once the national standards are issued, on the one hand, it means that the legal status of low-speed electric vehicles has been recognized by the state. On the other hand, lithium battery to replace lead-acid battery must be imperative, when lead-acid battery enterprises will face the situation of elimination, lithium battery enterprises will usher in a broader market.
