It can be said that the power lithium battery is the "heart" of pure electric vehicles.

　　In traditional cars, the engine is the heart of the car. Automobile companies all over the world have their own engines and master key components such as diesel engine technology and production processes according to their own mastery, so as to ensure the core competitiveness and profit of the brand.

　　As far as pure electric vehicles are concerned, the key vehicle power system is a large three-electric system composed of rechargeable battery system software drive system software motor control. In particular, the cost share of power lithium batteries is the largest, exceeding 30%, and the technology is still fast iterative.

　　According to the supply report of the international analysis agency UBS (ubs), as of the end of 2018, rechargeable batteries accounted for 25-40% of the fixed cost of pure electric vehicles, making it the most expensive component to date.

　　According to organized forecasts, by 2030, the global lithium-ion battery market will reach around 250 billion euros.

　　The development potential of power lithium batteries is huge, which is related to the leading force in the formulation of manufacturing standards. What we don't know is that automobile companies have a traditional idea that it is difficult to produce lithium-ion batteries without independent investment.

　　Daimler co-founded li-tec with evonikindustriesag, and in 2010 built a lithium-ion battery lithium-ion power plant in Lenitz. Soon after completion, it was announced in November 2017 that lithium-ion manufacturing will be fully completed by the end of 2016, and li-tec will become Daimler’s holding company, and most of the workers are in Daimler. In a subsequent interview, cai announced:

　　According to the current state of technology, Daimler cannot obtain all the economic benefits of manufacturing lithium-ion lithium-ion batteries.

　　Another German car tycoon: BMW s5 series. At the next GEN Future Summit, COO Nicolas Peter (nicolaspeter) announced that not every car company has to produce rechargeable batteries.

　　The reason for BMW is very simple. Once the battery R&D and production have to invest a lot of money, it is difficult for electric vehicles to make a profit, and there is no need to spend money on it. Secondly, once you have this idea, you will not be able to achieve self-sufficiency in a short time, but it will make the supplier feel uncomfortable, which will affect the current supply chain at that time, and the gain will not be worth the loss.

　　BMW’s words are not unreasonable. Last year, Nissan sold its battery business because of the huge investment over the years but the lack of profit and the energy involved. It is better to abandon it and concentrate on the development of other technologies for electric vehicles.

　　It's better to buy than to make. "The giants reluctantly gave the most realistic answer.

　　Of course, this may be the best choice.

　　Because, in fact, power lithium batteries are not easy to make.
