What are the core technologies of TeslaMotors in the field of electric vehicles?

The best thing about Tesla is the integration of existing technologies. The core technology is battery box integration. From the mechanical structure: the overall arrangement of battery box, cooling system, etc. The most important thing is the battery management system: how to effectively balance the voltage and current between the cells and keep the overall voltage and current stable during the charging and discharging process. The hardware and algorithm of this system are very important. Tesla's high mileage is mainly due to many batteries, but the cost is relatively high. Leaf, volt and other cars are mainly limited by cost. In addition, if you have heard of a car named rimac concept 1, you will find that the mileage of this car is actually very high, but the price is basically the level of Lamborghini going up. As a result, Tesla has no rival in the high-performance electric vehicle market with 10W knives for the time being. In addition, speaking of super chargers. Super charger is also a very important aspect of Tesla technology integration. Rimac mentioned above, although the battery has high mileage, high speed and high price, does not have Tesla's ability to provide overall services. High-performance AC motors and inverters are actually produced by many manufacturers, such as AMK, YASA in Germany and SEVCON in Britain. . . Wait a minute. But because it is only a motor manufacturer, not a car manufacturer, there is no need to be a driving unit like Tesla. Technically, the whole drive unit is mainly machined, because it is just equivalent to making a shell and then putting the motor and motor controller in it. Many people say that the touch screen inside is very powerful. But in fact, I think any big manufacturer can make such a system. The UI uses a touch screen, the operating system uses linux, and then I/O communicates with various control modules on the car to control various servo motors, speakers, cameras and so on. None of this is new. The greatness of Tesla is that it puts all these things together and gives everyone a completely different product experience. From a big perspective, most of the current scientific and technological products are the integration of existing technologies. Only a few companies, such as Intel, have a research level no less than that of universities can we say that there may be a revolutionary breakthrough in basic disciplines. The so-called basic disciplines, revolutionary breakthroughs, such as the invention of triode, led, C language, and so on.
