What are the characteristics of Tesla's battery control technology?

From the battery technology to build a Tesla within a few minutes. In view of Wang Chuanfu’s word to build a Tesla in minutes, the author analyzes the Tesla models from a technical point of view. The source comes from the Internet. Including data, assessments, measurements, videos and skills information. Combining the basic principles of automobile skills, as well as the most basic knowledge of physics, chemistry, computers, information, battery knowledge, hybrid power and so on. Try to be objective and fair. 1. What is the core skill of ModelS? The core skill is software, which mainly includes battery management software, motor and electronic control skills of vehicle equipment. The most important skill is battery control. The acceleration function, range and control function of ModelS are all based on battery control skills. Without battery control skills, everything will cease to exist. 2. What are the characteristics of ModelS's battery control technology? The most matching model S uses nearly 7000 Panasonic NCR186503100mah lithium batteries, two sets in series and parallel. Sensors are set to sense the working status and temperature of each lithium battery, and the lithium battery is controlled by the battery control system. Prevent dangerous situations such as overheating and short-circuit temperature difference. In daily use, it is necessary to ensure the safety of lithium batteries under high current discharge. Other manufacturers use large batteries, only a few hundred at most, without precise control systems. 3. Why is the battery control system so messy? In order to be able to use the powerful 18650 cobalt lithium battery. High-performance lithium batteries have brought high-performance cars. Due to the high risk of the 18650 cobalt lithium battery, the safety of the system cannot be guaranteed without a reliable system. This is why most manufacturers are reluctant to use cobalt lithium batteries in electric vehicles, electric vehicles and hybrid vehicles, especially in large-capacity batteries. Panasonic NCR186503100mah, in addition to the best test consistency, it has many charge and discharge times and relatively good safety. The most important thing is energy, light weight, and low price. Due to its high energy and light weight, it can install more batteries for the car within the weight limit of 2 tons, thereby ensuring a longer driving range. Because the output current of the battery is limited, the more batteries, the greater the output current and the greater the power, the more motor power can be used. The greater the power of the engine, the greater the power of the engine, the faster the car will accelerate and last longer. 4. What are the advantages of Model S cars? Do electric cars have these advantages? As a car, Model S has the following advantages (1) Fast start, the excellent version can accelerate from 0 to 100 kilometers in more than 4 seconds, which can rival the advantages of BMW M5 Source: The motor has a large starting torque. It requires a period of time from the engine to the maximum torque. The motor starting torque has a natural advantage. The engine can only adopt the form of the ejection speed of the crane, taking the damage to the gearbox as the value, increasing the starting torque, and improving the acceleration function of 0-100 kilometers. (2) The source of static, smooth, and smooth advantages: The motor is related to the natural advantages of the engine. The motor rotates directly, without the reciprocating movement of the piston of the engine, there is naturally no vibration. The noise is much lower. The motor has a high torque speed range, which can prevent temporary loss of power and no shift shock during gearbox and transmission. (3) Strong operability and good pile replacement effect. Advantage source: In fact, the suspension has no advantage. It is the same as the engine car, except that the heaviest battery of the electric car is on the middle chassis, the center of gravity is in the car, and the azimuth angle is very low. The engine itself is very small, and between the rear axles, the azimuth angle is also very low, and the center of gravity is much lower than that of the car's engine. The center of gravity is in the middle of the car, which is equivalent to the center of the car. Rear-wheel drive is a type of rear-wheel drive. Compared with the best horizontally opposed engine, it is driven after the center is installed. (4) The source of the advantage of low price, the motor is cheaper than the engine of the same horsepower, the structure is simpler, even with the battery. It is also lower than an engine with a gearbox and transmission system. The price of the Tesla ModelS is comparable to that of the Audi A6, but its features are the same as the BMW M5. (5) Excellent ergonomics, a strong sense of science and technology, and the advantages of a central control station that surpasses the industry. This is actually not related to electric vehicles. Fuel vehicles can also do the same. It is more of a geilige with an IT background. What do you know? It is the user experience. This is the symbian dispute between iphone and Nokia.
