It ranks fifth in total battery installed capacity and second in ternary field. By the end of 2017, BAK had accumulated more than 110,000 vehicles and achieved zero battery safety accidents.
"The new energy vehicle purchase tax preferential policy will be extended for another three years." This is a major positive news announced in the report of the two sessions.
Beginning in 2008, the annual prime minister report will mention the new energy vehicle industry. Even if the subsidy dividend is completely withdrawn in 2020, the invisible dividends such as tax exemption, licensing, and road rights will continue for some time. Under the stimulation of the double-point policy, the competition in the domestic new energy vehicle market will become more and more fierce, but it is a very good development opportunity for the entire Chinese automobile industry chain.
Interpretation of "Made in China 2025", "energy-saving and new energy vehicles" has become a key development area, pointing out the direction for the development of China's energy-saving and new-energy automotive industry. For the core components, "Made in China 2025" gives a clear goal.
"By 2020, key systems such as power batteries and drive motors will reach the international advanced level and occupy 80% of the domestic market. By 2025, key systems such as power batteries and drive motors will be exported in batches."
The power battery is the core component of the new energy vehicle, and the cost accounts for 40% of the whole vehicle. If you want to become a new energy vehicle power, China's power battery must maintain a technological advantage compared with the international. According to the information released by Tesla in 2017, the energy density of 18650 cylindrical power battery produced by Panasonic is about 250Wh/kg, while the energy density of 21700 monomer has reached 300Wh/kg. Ouyang Minggao, executive vice president of China Electric Vehicles 100, also predicted that while the power battery will increase the technical level, the cost will also be reduced to 1 yuan / Wh.
As one of the few companies in China that focus on cylindrical power batteries. Shenzhen BAK Power Battery Co., Ltd. (abbreviation: BAK) achieved good results in 2017: it ranked fifth in battery installed capacity and second in ternary field. By the end of 2017, BAK had accumulated more than 110,000 vehicles and achieved zero battery safety accidents.
How to achieve high quality and low price?
As we all know, under the environment of rising raw material prices and subsidies gradually declining, power battery companies are facing double pressure. For how to achieve high quality and low cost of power batteries, BAK has three preparations:
1. By increasing the specific gravity of the positive electrode material of the power battery, reducing the cobalt amount, reducing the pressure of the upstream raw materials, and reducing the cost of raw materials:
As the first battery company in China that can use nickel high 811 material to achieve bulk supply, BAK's 2.75Ah ternary high nickel power battery cell (18650) energy density has reached 240Wh / kg, and can effectively guarantee the battery Works normally in extremely harsh high and low temperatures. In 2020, BAK's 18650 cells will have an energy density of 300 Wh/kg.
2. Increase production scale, complete intelligent manufacturing upgrades, and achieve and increase economies of scale:
While mass production of existing products, BAK is also committed to the development of high energy ratio 21700 cylindrical power battery cells. Compared to the previous 18650 products, the Buick 21700's monomer energy density increased by 35%, component weight reduced by 10%, system cost decreased by more than 9%; from 4.5Ah to 4.8Ah products, more than 1000 cycles can be achieved. The capacity retention rate is greater than 80%.
The BAK 21700 cylindrical power battery unit has been mass-produced and is expected to be mass-produced in 2018. Today, BAK has established two production bases in Shenzhen and Zhengzhou with a total annual production capacity of 8GWh; in 2018, BAK will further expand its production capacity to 12GWh; according to this expansion rate, it is estimated that by 2020, the total of BAK The annual production capacity will reach 20GWh.
3. Cooperate with the whole vehicle company and customers operated by third parties to achieve mutual benefit and win-win:
In 2017, BAK achieved the fifth place in battery installed capacity and the second in the ternary field. It also cooperated with many domestic large-scale vehicle manufacturers, such as Jianghuai, Dongfeng, Zotye, Huatai, Haima, Great Wall, Cheetah. Beiqi Foton, Southeast Auto, etc., while BAK also provides a powerful "new heart" for new energy vehicles such as Yundu, Xiaopeng, electric coffee, singularity and zero-speed.
What is the magic of smart manufacturing?
BAK Battery is the first power battery company in the industry to propose the concept of intelligent manufacturing, and has always insisted that it has accumulated more than ten years of experience in the field of automated production and intelligent manufacturing. As early as 2006, BAK completed the construction of the first automatic 18650 battery production line in China, and insisted on promoting intelligent manufacturing upgrades, building a smart battery manufacturing system, and realizing the platformization, dataization and intelligence of production process control. Now, the smart manufacturing that Bik has laid out in advance is already at the domestic leading level, the international advanced level, and the results are remarkable.
Not long ago, the first electric network had visited the power battery smart factory of Zhengzhou BAK Battery Co., Ltd. (referred to as: Zhengzhou BAK), a wholly-owned subsidiary of BAK Battery. Zhengzhou BAK Smart Factory has built an automated and intelligent unmanned workshop, focusing on 18650 batteries from module to package manufacturing. The overall production capacity is 5GWh, and the daily output can reach one million. The production efficiency is 116% higher than before. Reduced consumption by 15%.

By selecting highly automated smart devices, BAK ensures the consistency of the cells from raw materials, design, testing, etc. In this process, it includes various process control, data tracking, data analysis and so on. At the same time, BAK has realized a "one core and one code" battery life cycle data tracking and tracing system. Data control from the raw material of the battery core, using big data management to realize the data tracking of the battery life cycle, which is equivalent to each battery has its own ID number, which is also convenient for entering the battery early in the recycling process. Digitization.
Perhaps within the next five years, the three packs of soft packs, squares and cylinders will coexist. All three technical routes have their own advantages and disadvantages. From the perspective of the choice of international car manufacturers, all three routes are widely used.
The use of highly automated and mature processes to ensure the consistency of the battery, through the expansion of intelligent production line to bring quality upgrades, through intelligent manufacturing and upgrade to achieve high quality and low price, this is the surprise of the Beck cylindrical power battery. Under the premise of ensuring safety, stability and long life, with the increase of energy density of power battery, electric vehicle owners will eventually get rid of the troubles caused by “mileage anxietyâ€.
