202 1-2022 BYD Auto's year is a "crazy growth period". As an automobile brand that has almost given up fuel vehicles, it mainly focuses on pure electric and plug-in hybrid power. In February, its sales volume may rank first among manufacturers, surpassing well-known automobile companies such as SAIC Volkswagen, SAIC-GM, Geely and Great Wall. How can BYD make a large number of consumers put aside their prejudice against new energy vehicles and China automobile brands? In fact, text reading can't make readers feel intuitively, and so can video. Only by driving in person can you experience the real driving quality, quietness, acceleration and intelligence of the vehicle. Once the test drive, BYD will basically have more users.
I use BYD Qin plus-dmi. Tell me how I feel about using a car. Plug-in hybrid vehicles can be petrol-electric, and pure electric vehicles can be 10 cents. If a pure electric car turns on the heating in winter, it is about 20㎞ (my car is version 55㎞). If you want to save money to buy pure electricity, after all, you have to increase the regular maintenance cost if you have an engine. In addition, in the case of losses, false bidding is very serious, especially the performance of 3.8L/ 100㎞. In fact, the bid that will definitely be shorter than 100 ㎞. Now it is 8,000 ㎞, and the charging fee is 700 yuan. Come on, 1200. The comprehensive cost is about 30%.
Let's start with BEV (pure electric vehicle). Is there any noise in the fuel truck, which will almost cause vibration, and sometimes there may be high temperature? The answer is yes. Because the engine used by the fuel vehicle is an internal combustion engine, high temperature and high pressure will affect the service life and driving quality of the engine according to the heat conversion power generated by the fuel; This engine is not suitable for high-speed operation. Because the conversion power loss ratio is high, a lot of fuel is actually wasted, so it is necessary to control the speed of the transmission. The complicated transmission device increases the maintenance cost, and also causes inevitable shortcomings. Electric vehicles do not have these problems, because the conversion power of the motor depends on the magnetic field formed by the current, and the current transmission is silent. The motor structure is very simple, the failure rate is very low, and there is almost no noise. The key is that the motor has no wear problem, as long as there is no collision, unless the water is defective, but this is a technical problem. Because of its simple structure and extremely low loss, the motor can run at ultra-high speed, and the maximum speed of Formula F1,the extreme racing car in fuel vehicles, is also lower than that of the motor. The engine of an ordinary scooter is only six or seven thousand revolutions, and the motor can easily exceed1.50 thousand revolutions.
Ultra-high speed determines that speed can be adjusted without transmission, power can be adjusted by speed, and wheel speed can be adjusted directly by power; Skip the transmission and directly drive the wheels, so there will be no problem of gear shifting, so the driving quality of electric vehicles exceeds that of fuel vehicles. After understanding the advantages of electric drive system, we need to understand BYD's technical level and the advantages of the whole industry chain model; BYD independently developed lithium iron phosphate battery (blade battery) and lithium nickel cobalt manganate battery (ternary lithium). These two kinds of batteries have reached the top standards in the industry and become the choice of many Chinese and foreign automobile enterprises; You know BYD itself is a car manufacturer. Considering that suppliers will be rejected by friends, otherwise you can choose display technology to have advantages. Besides power battery, BYD also produces its own battery IGBT &；; MCU chip, with permanent magnet synchronous and AC asynchronous motor, can develop and produce ABS/EBD/TCS/VDC, which together is ESP；; Secondly, the car machines, wiring harnesses, tablet computers and light sets used in the car are also produced by ourselves, and we can see the advantages and disadvantages from the sales level. BYD is a real R&D enterprise, and it is the automobile enterprise with the largest number of new energy vehicle technology patents in the world.
