“Our Taiyuan taxi has long been replaced with a new energy vehicle. 'A few days ago, reporters found on the streets of Taiyuan, Shanxi: The cabs run by Mancheng were all blue and white BYD pure electric vehicles. A taxi driver who drove for us. Told reporters, 'I was the first to open a new energy vehicle. At present, nearly 10,000 taxis in Taiyuan could not find a single fuel. This is also the first case in the country.'
The driver was very talkative: 'This 300,000 yuan car has enjoyed state subsidies. It took less than 100,000 yuan to get it. It's quite good.' The driver told the reporter proudly. When the reporter asked how much energy the car charged At a time, the driver replied, 'If this car ran over 300 kilometers, it wouldn't dare to run anymore. It would be afraid of leaving the road. However, if Taiyuan is not big enough, it would be enough to run for one full night.'
Afterwards, the reporter also asked about the long distance and cost. The taxi driver said that as long as it is in all expressway service areas in Shanxi, there are charging piles. Some hotel parking lots also have charging piles. Then, the driver showed up. The mobile phone opened an APP and told the reporter that this was the location of all the charging piles in Taiyuan City. When the fuel tanker was opened, a box full of oil was added to nearly 300 yuan, and now it is full of electricity for sixty to seventy yuan, and the night charge is cheaper.
According to reports, in recent years, China's new energy automotive industry has developed rapidly, especially in the field of pure electric vehicles, and has become the world leader. In 2017, the production and sales reached 774,000 units, and the number of holdings was 1.8 million. The industry estimates that the production and sales will exceed 2020. 2 million vehicles. With the rapid expansion of the new energy automotive industry, it has also led the development of the lithium ion power battery industry for the core components of new energy vehicles. 'At present, lithium ion power batteries are used in performance stability and technology maturity. New energy vehicles are the most suitable. 'Wang Jianzhong, full-time vice chairman of the China Battery Association and president of the Waste Battery Recycling Branch, told reporters. In recent years, the state has invested several hundred billion yuan each year in the development of new energy vehicles. Incentives, the amount of holdings increased year after year, the contribution to urban air quality can not be underestimated, comply with the general trend of environmental protection.
Wang Jingzhong stated that the production volume of power lithium-ion batteries is increasing, showing a trend of rapid development. New technologies, new materials, and new systems are constantly emerging, system performance is continuously improving, technology content, product quality and Japan and South Korea belong to the same period of development, and China has become an international player. One of the three major lithium ion battery manufacturing countries. 'New energy vehicles are facing important problems, the battery mileage problem has always been a bottleneck in the development of the industry. 'Wang Jingzhong introduced that the power lithium ion battery energy density is not enough, more mileage in the 350 kilometers, and the battery life is only four or five years. At present, the cost of new energy vehicles is relatively high, the cost of the battery accounts for about half of the vehicle. New energy vehicles in the sales of countries to give a lot of subsidies, probably account for the entire vehicle price From 60% to 70%, that is to say, consumers now buy a new energy car and spend 100,000 yuan. In the next 4 or 5 years, the battery will be scrapped, and it will cost a lot of money to replace it.
At present, more than a dozen power lithium-ion battery companies have established state-level enterprise technology centers and engineering centers, and have increased their efforts in basic, critical, and common technology research and development, and are looking forward to realizing the cost and battery life of the power lithium-ion battery in the near future. Mileage problem.
Wang Jingzhong believes that 'battery technology is not just a development path. As a hydrogen fuel cell with higher energy density, it may become a new energy technology that can be truly relied on in the future. Adding a bottle of hydrogen fuel can run for 1,000 kilometers at a hydrogen exchange station. It can be replaced in 3 minutes. The principle of this type of fuel cell operation is that hydrogen and oxygen are reversed in the fuel cell to become automotive power and produce water after reaction. It is truly zero pollution to the environment.
Of course, the large-scale adoption of hydrogen fuel cells at this stage still has huge technological gaps that need to be crossed. For example, the use of platinum in the catalytic materials of fuel cells is very costly. At present, alternatives to platinum materials are still being studied. Once the battery can overcome the cost of the catalyst and other problems, the traffic revolution and even the energy revolution brought about by it will be subversive.
