The automatic control systems of Tesla and Tesla mostly come from dealers, but the electronic control technology is independently developed. The most important electronic control technology is battery management system, which is the foundation of all new energy vehicles and the most difficult core to manage. In order to ensure the battery life, quality, environmental temperature, condition, normal battery charging safety center and overcharge management in different environments, "BMS" is a manager specially controlling all battery power, environmental temperature balance and battery life maintenance.
The new energy electric vehicle is composed of several batteries, all of which are dominated by batteries. Each rechargeable battery may be overcharged or overdischarged, which will lead to problems in the power supply system, shorten the service life of rechargeable batteries and endanger the loss rate of the vehicle. Therefore, the motor control group is the "cardiovascular" of all pure trams and plays a leading role. BYD Electronic Control System and BYD Auto can compete with Tesla Auto Market only because their products are independently developed, produced and sold. The main IGBT semiconductor technology of BMS is very perfect, far superior to IGBT processing chips such as Mitsubishi Siemens system.
Its electronic control system is basically the same as Tesla's, but their battery charging time is different. Tesla must charge for 60 minutes, while BYD can charge the battery in 42 minutes. Tesla is only better than BYD's patent right, because he created the patent right and submitted the registration application first, and there are many patents. BYD Auto also goes hand in hand. However, in terms of electronic control, Tesla is indeed ahead of BYD. For BYD car trams, it is even the first, and other car groups are even more backward.
The role of car batteries, for trams, rechargeable batteries are fuel tanks. Tesla's batteries are mainly supplied by two or three dealers, usually Konka. Among them, the rechargeable battery of LG Chemical Plant can reach 605 kilometers, and only the rechargeable battery of Ganfeng Lithium Industry can last 468 kilometers. This is not enough for everyone's car owners. All this is in everyone's mind. BYD Hanergy's new energy electric vehicle uses the "cutter head" rechargeable battery made by its own enterprise, and the mileage is also divided into several grades. Specification 506km, long rechargeable battery 605km, 4WD high performance vehicle 550km.
In contrast, Tesla and BYD have reached this level, but the volume is completely different from the 100 km acceleration. The capacity of Model3 is 76.8kwh, and the acceleration of 100 kilometers takes only 3.3 seconds. The battery capacity of Hanergy's new energy vehicle is 76.9kwh, but the acceleration of 100 kilometers takes 7.9 seconds, which is more than half slower. You have to ask, if this is the enemy, is there such a big difference? This is the raw material used in their manufacturing process. Tesla uses ternary lithium batteries and BYD uses lithium polymers.
