Chapter 37 (1/2)
The design of Tieniu x went on smoothly. To put it bluntly, it was designed according to the sports car at the beginning, and forced the appearance to look like a tractor.
The structure of electric vehicles is not like traditional cars, and the design work is relatively easy.
There are a lot of knowledge in traditional cars, including engine, transmission mechanism and transmission system, each of which can deeply affect the final comprehensive performance of the car.
Squeezing the performance of these parts to the limit has become a high-end sports car. However, due to the sharing of the R & D cost, although the high-end sports car is expensive, it is still at a serious loss.
Behind every super sports car brand, there is a large car enterprise as the backing. They focus on honing technology in this process. Therefore, traditional cars are a very high threshold field.
The electric vehicle is different. It eliminates all these troubles and is replaced by four independent motors that directly drive four tires.
Therefore, there is no engine, no transmission mechanism, and the speed change is realized by adjusting the current by software.
Traditional cars try their best to improve the performance of all parts and divide the car into high grades. In fact, there is a big gap, such as 100 km acceleration time at start-up, energy conversion efficiency, service life, noise and so on.
But electric cars don't have to worry about these problems. Indicators such as 100 km acceleration time naturally beat the top sports car.
Not only that, the four drive motors of electric vehicles can also be directly purchased in the market at low price and high performance, and there is no gap in this regard.
The structure of traditional cars is complex. It is difficult to integrate so many complex structures into the car, so the appearance design is also limited.
But electric cars are different. To put it bluntly, the positions of the four drive motors must be pasted next to the wheels, and then leave room for the battery. You can design it as you want, and you can design the front cover of the car as a storage box.
Therefore, we can always see that no matter how low the price of existing electric vehicles on the market is, they always have a very avant-garde appearance.
The only difficulty of electric vehicle is battery and battery management technology, among which the difficulty of battery is cost and cost performance.
However, due to the perfect industrial chain, the batteries of electric vehicles can also be purchased casually in the market, including tens of thousands of rechargeable batteries the size of No. 5 battery bought by the leader Tesla, and then tied together.
Of course, there are also enterprises specialized in making batteries to enter this industry and launch special batteries for electric vehicles.
But in the end, the core difference of each electric vehicle enterprise is power control technology.
This technology can give full play to more than 30% of the service time of batteries through the accurate control of tens of thousands of small batteries and the most reasonable allocation of tasks.
At the same time, battery and power management system accounts for half of the cost of electric vehicles.
However, Liang Shicheng does not intend to make too many breakthroughs in battery and power management technology in a short time. He can only choose ready-made products and solutions in the market.
Since Tieniu x wants to reduce the cost, it must sacrifice many design indicators, which makes it destined not to be a complete sports car.
