Why BYD's power battery is more advanced than other companies

March 2, the haze topic to start the year for the first time to push up new energy vehicle stocks. Subsequently, the national two sessions during the March 5, the country's top management repeatedly mentioned the importance of the development of new energy vehicles, the day, the second wave of upward wave swept the new energy vehicle stocks, Wanxiang Qianchao, Desai batteries, Foshan Plastic Science and Technology and other stocks led the way up, BYD halted.

"Although whether automobile exhaust is the main source of haze, there are still many debates. But through the promotion of new energy vehicles, to replace traditional fuel vehicles, and gradually reduce automobile exhaust to govern the atmosphere, has become the government's governance **** knowledge." BYD insiders said.

The government in the haze under great pressure, the frequent launch of policies to support new energy vehicles, become a new energy concept stocks are fried gimmick. Batteries, new energy concept stocks are sought after, but some battery companies do not have the core technology, such as Wanxiang Qianchao and even new energy vehicles do not have a direct relationship, many stocks in the speculation has been reduced to a "demon stock".

The industry is more concerned about the government last year launched a new round of new energy vehicles purchase subsidies, free license plates, purchase tax exemption, charging facilities construction reform and other measures, the national policy can also be supported at what level?

"Last year's new energy vehicle policy, mainly focused on the field of market promotion, basically can think of ways, have been released or have formed the intention, and will gradually implement the formation of policy system. The next possible breakthrough area is the technical level, support for the industrial chain, which is also the most lacking in recent years." A study of new energy vehicle technology experts said on March 6 to the 21st Century Business Herald reporter.

Battery technology to make up lessons BYD power battery capacity several times higher than other enterprises! World-class!

New energy vehicle promotion has reached six years, support policies have also formed a system, but in areas such as scientific and technological innovation, the relevant support is not much, but also little attention from the outside world. As the Ministry of Science and Technology 863 plan major scientific and technological specialists in electric vehicles, Wang Binggang on China's new energy vehicle technology hollowing out is very worried, reminding the relevant departments to pay attention.

New energy vehicle industry **** knowledge is that the domestic new energy vehicle enterprises in the battery, motor, electronic control of the three core technologies, and the international advanced level is still a big gap. "Especially power battery technology, as well as hybrid power system, domestic except BYD has, many car companies not only no production line, and mass production does not come out of the model." Wang Binggang said.

China's power battery is mainly lithium iron phosphate, but the battery development level is uneven. According to data provided by the China Automotive Technology Center, most of the domestic use of lithium iron phosphate battery pure electric vehicles, battery capacity and other parameters are very different. For example, Kandi 4-seater electric car battery capacity is only 21.12 degrees of electricity, JAC iEV4 for 19.2 degrees of electricity, BAIC E150EV for 23 degrees of electricity, while BYD e6 can reach 60 degrees of electricity. BYD power battery capacity is several times higher than other companies! Reaching world-class!

"Domestic power battery production is still dominated by small production lines, many of the production level is low, consistency is difficult to ensure. A technology backward, the future may drag the whole industry development. Batteries and other core technology components, capable competitors will not provide you with, so despite the Department of energy vehicles get hot, but there are many crises." Beijing, a small battery company insiders said.

Power battery technology is considered by the industry as the most critical technology in the development of new energy vehicles. According to a source from China Automotive Research Institute (CARI), the country is studying the development of related policies and measures, the most important of which is to regulate and support the power battery of new energy vehicles.On February 16, the Ministry of Science and Technology released the "National Key Research and Development Program of New Energy Vehicle Key Special Implementation Plan (Draft)" (hereinafter referred to as the "Program"), which, from the development of the automotive industry to the control of automotive exhaust pollution, puts forward the following in the "New energy vehicles and some of the core components of the key technology is not a complete breakthrough," the need for technological upgrading.

The Ministry of Science and Technology to determine the technical support of the general direction are: electrification of energy science, lightweight materials science and intelligent information science. The vertical system supports pure electric power system, plug-in / supercharged hybrid power system and fuel cell system. Among them, the most core technology of new energy vehicles power battery, put forward a quantitative target, requiring the car power battery's single specific energy by the end of 2015 to reach 200 watt-hours / kilogram, doubled compared with 2010; in 2020 to reach 300 watt-hours / kilogram, the overall level to remain within the top three international.

Subsequently, local governments have also begun to follow up, Shenzhen recently released the "Shenzhen New Energy Development Work Program", Shenzhen will further promote the innovation capacity of the new energy automobile industry. Requirements by the end of this year, the overall technology of new energy vehicles to reach the international advanced level, the power battery module cost down to less than 2 yuan / watt-hour, the cycle service life stabilized to reach 2,000 times or more than 10 years, the power density of the electric drive system to reach more than 2.5 kilowatts / kg.

Because of the weak fuel cell technology reserves, car companies are reluctant to invest huge sums of money to start from scratch, the Ministry of Science and Technology is very despondent about this, but in the industrial route is still not clear, can not directly give up. Fuel cell vehicle target is also set very low, before 2020 only requires "fuel cell vehicle technology breakthroughs, to meet the requirements of industrialization, to achieve a thousand market scale."
