Ternary lithium battery and lithium iron phosphate battery which is more suitable for the electric car?

Source: 2020 - 03 - 28 40 hits: ternary lithium ion power battery and lithium iron phosphate battery which is more suitable for the electric car? On February 18, 2020 at noon, tesla announced is discussing with ningde using lithium iron phosphate as domestic type 3, shocked the industry. Tesla had been using 18650 ternary lithium batteries. Under the influence of the ternary lithium battery, our country most of the traditional and new creation car battery also USES three yuan. The tesla: why do you want to consider using lithium iron phosphate batteries? Two of the most important reason is the price and cycle life. The first is the price. According to the introduction of ouyang minggao, member of Chinese Academy of Sciences, lithium iron phosphate KWH capital system now can reach 600 yuan/KWH, and 811 kilowatt hours of ternary system of funds, even like tesla was a fear of 1000 yuan/KWH, even higher, ordinary new energy car companies may need to 1200 yuan/KWH. Battery at 50 degrees of grains such as car model, for example, if you use the lithium iron phosphate, capital is 30000 yuan, use lithium battery, 3 yuan capital in - $50 60000 yuan between. 2 - 30000 yuan of BOM cost difference for OEM is very high. As the new energy vehicles subsidies to reduce and stop, the electric car will have to rely on to lithium iron phosphate and gasoline vehicle competition on price. The bill is very easy to calculate. An official pricing for the $150000 of fuel car, BOM is usually 10. 50000 yuan. Generally speaking, the fuel vehicle powertrain is about 25% of the cost of BOM, about 26000 yuan. If you use the lithium iron phosphate package, the cost as low as 30000 yuan, 5000 yuan plus other motor driven system. In addition to the two point, tax reduction policy factors, such as electric cars more expensive than fuel vehicles thousands of yuan more, very competitive. The other one is the battery life. Although in different given situations there will be some different data, but in general, common use ternary lithium battery electric vehicle charging cycles of about 800 times, and the use of electric vehicle charging lithium iron phosphate cycles of about 2500 times. Hypothesis model NEDC after a full charge mileage of 500 kilometers, the tern lithium battery electric vehicle the whole life cycle of a total mileage of 400000 kilometers, and the lithium iron phosphate electric vehicles in the whole life cycle of the total range of 1. 25 million km. As for private cars, in its life cycle, they can run 200000 to 300000 kilometers, 400000 kilometers of the battery life basically is enough. But for certain types of commercial vehicles such as taxis, buses and trucks, more competitive, lithium iron phosphate as a rental car can easily travel 1 million kilometers in a few years time. If use ternary lithium battery, need to buy a car, three times with the lithium iron phosphate, buying a car is enough. This is to be on the safe side, in the commercial vehicle classes, in energy storage class, lithium iron phosphate in a dominant position. But once realized the automatic control function, even private cars, the requirement of battery total distance will also be greatly improved, because it will greatly improve the utilization rate of private cars. Artificial intelligence (tesla developed automatic driving 自我 驾驶AI) FSD chips are batch load. Musk says he hopes to have a driverless taxi team at the end of 2020, plans to produce 1 million cars. In this case, prolong the cycle life of lithium iron phosphate, of course, is a better solution. The domestic manufacturers to do? Below for our country automobile industry for many years the lithium iron phosphate batteries and ternary installed capacity of battery. You can see that the ternary ratio rise year by year, is currently in the mainstream status. However, at the same time, it is important to note that since 2019, the domestic OEM will start from scratch using lithium iron phosphate as a result of the subsidies and poor safety of serious setback ternary batteries, and tesla's demonstration will further accelerate the speed of domestic transformation of lithium iron phosphate. The development trend of domestic should be: ( 1) Commercial vehicle and energy storage is mainly the lithium iron phosphate. ( 2) Hybrid cars mainly made from lithium iron phosphate and. ( 3) Passenger cars are divided into mid-range vehicles/high grade cars, use lithium iron phosphate; High-end models/special high-end machines, 3 yuan. By 2020, the market will have a lot of models of lithium iron phosphate, let's wait and see.
