Why four-wheel low-speed electric vehicles should not exclude lead-acid batteries but only lithium batteries?

The country during the two sessions this year, the National People's Congress on behalf of the group chairman, day Zhang Tianren, submitted to the thirteenth session of the National People's Congress (NPC) a meeting on adhere to market-oriented, two-wheel driven development of four-wheel low-speed electric car industry, meet the diversified demands of the new era of transport advice.

In recent years, four-wheel low-speed electric vehicles as a new kind of short-distance transport, with a "green environmental protection, energy conservation and emissions reduction, economical, convenient safe" characteristics, welcomed by the people and the market.

On October 13, 2016, the state council clearly put forward "upgrade a batch, standardize a batch of elimination, a batch of" opinion.At present, the conditions of four-wheel electric vehicle technology at low speed (draft) is developing, the lead-acid battery has been left out in the technical conditions is the key to critical.

Zhang Tianren thinks, four-wheel electric vehicle technology at low speed conditions out of lead-acid battery is not reasonable.The reasons are the following:

First of all, if the draft requires power battery products can only use the powerLithium ion batteries, it will be no countries have issued with attributes on the implementation of standards, it is not serious unfair.

Second, it will deviate from China's national conditions and common market mainstream four-wheel low-speed electric vehicle power battery, it is not scientific.Lead battery has a history of over 170 years, mature technology, safe and reliable, the price is low, is widely applied, the current round of low-speed electric car market more than 95% with are lead-acid batteries, lead-acid batteries in fuel usage is less than one over ten of the car.

Third, it will cause the lithium resources waste and the potentially huge environmental pollution hazards, is out of the loop is not environmental protection.80.54% of China's proven reserves of lithium resource type is salt lake type, accounting for about 80.54%, in the process of mining and processing is very easy to damage to the fragile ecological environment of qinghai-tibet plateau.And China has yet to establish waste lithium battery recycling system, according to the measure, is expected in China in 2018Power lithium battery scrap amount will reach 14 GWH, more than 170000 tons, will cause great pressure on the environment.

Based on the above analysis, Zhang Tianren puts forward three Suggestions:

One is to stick to market leading, two-wheel driven, encourage a variety of technical route in parallel.Encourage learning experience of developed countries, is preferred lithium ion power battery innovation and development at the same time, do not reject lead-acid batteries are widely used and development.

Second, insist on government regulation, fair, science and technology standards.Very much looking forward to for a "technical conditions" standard work in under the guidance of the relevant department, the battery industry and vehicle manufacturers, expert advice give full understanding and attaches great importance to, guide and coordinate the relevant association, society and standardization technology organizations, correct prejudice against lead battery, strengthen to the identity of all kinds of gb standard.

3 it is to stick to that lead, pilot promotion to the sustainable development of four-wheel electric car industry with high quality at low speed.
