"Build a tesla in minutes?

yd wang chuanfu's "build a tesla in minutes" comment, the author analyzes tesla models from a technical perspective. The source is the Internet. Including data, evaluation, measurement, video, technical data. Combined with the basic principles of automotive technology, and the most basic physics, chemistry, computer, material knowledge, battery knowledge, hybrid power and other common sense. Strive for objectivity.

. What are the core technologies of the ModelS?

he core technology is software, mainly including battery management software, motor and electronic control technology of vehicle equipment. The most important is battery control technology.

he acceleration, range, and handling capabilities of ModelS are based on battery control technology, without which everything would be lost.

hat are the characteristics of the ModelS 'battery control technology?

he top ModelS use nearly 7,000 panasonic NCR186503100mah lithium batteries, which are grouped twice and connected in series and parallel. Sensors are set to perceive the working state and temperature of each lithium battery, which is controlled by the battery control system. Prevent overheating short circuit temperature differences and other dangerous conditions.

n daily use, to ensure the safety of lithium battery in large current discharge.

ther manufacturers use large batteries, a few hundred at most, and don't have control systems that are accurate to each cell.

. Why such a complicated battery control system?

o be able to use high-performance 18650 cobalt-lithium batteries. High-performance lithium batteries bring high-performance cars. Because of the high risk of 18650 cobalt-lithium batteries, safety cannot be guaranteed without a reliable system. That's why most manufacturers -- electric cars, plug-in electric cars, hybrid cars -- are hesitant to use cobalt-lithium batteries, especially for high-capacity ones.

anasonic NCR186503100mah, in addition to the test consistency is the best, charge and discharge times, the safety is relatively good, the most important is the energy, light weight, price is not high.

ecause of its large energy and light weight, it can fit more batteries into the car within the weight limit of 2 tons, thus guaranteeing a longer range. Because of the limitation of the battery output current, the more the battery, the larger the output current and the larger the power, the larger the motor power can be used. The greater the power of the motor, the greater the power of the engine, the faster the car will accelerate, and it will last for a long time.

hat are the advantages of ModelS as a car? Are these advantages brought about by electric cars?

s a vehicle, ModelS have several major advantages

1) fast starting acceleration, top matching version 0-100km acceleration 4 seconds, can fight BMW M5

dvantages: the motor has a large starting torque, and it takes some time for the engine to start up to the maximum torque. The motor has a natural advantage in starting acceleration. The engine can only use the ejection mode to lift the speed, at the cost of damaging the gearbox, improve the starting torque, improve 0-100km acceleration performance.

2) quiet, smooth and smooth

dvantage source: motor relative to the natural advantages of the engine, motor direct rotation, no engine reciprocating piston, natural no vibration. The noise is much less. The large torque and high speed range of the motor can be used without gearbox. There is no power loss in the gearbox transmission process and no shift impact.

3) high maneuverability and good performance in pile-winding line variation.

ource of advantage: suspension actually has no advantage, and start a locomotive the same, but the electric car's heaviest battery in the middle of the chassis, the center of gravity in the car, and the position is very low. The motor itself is very small, and also between the rear axles, very low position, the center of gravity is lower than the horizontal engine car.

he center of gravity is in the middle of the car, which is equivalent to the layout of the center. The rear wheel drive belongs to the rear drive. The motor and battery position are very low, and the center of gravity is lower. Better than the best horizontal opposed engine, the mid rear drive.

4) low price

he advantage comes from the fact that electric motors are cheaper and simpler to build than comparable engines, even with batteries. It is also lower than a set of configurations such as engine plus gearbox plus transmission. The tesla ModelS are comparable to the price of the audi A6, but comparable to the BMW M5 in performance.

5) excellent man-machine engineering, strong sense of science and technology, and the central console exceeds the industry

he advantage comes from the fact that IT has nothing to do with electric cars. IT can also be done with fuel cars. IT is more about gelige's IT background and what is user experience. This is equivalent to the difference between the iphone and nokia symbian. One is comfortable, one is usable.

6) large space, front and rear luggage

he advantage comes from the fact that the motor is much smaller than the engine and has no gearbox, intake pipe, turbocharger, exhaust pipe, ternary catalysis, transmission shaft and so on. The battery is combined with the chassis to save more space than the fuel tank.

hat are the disadvantages of ModelS?

1) cannot use oil, can only charge, and does not match the existing infrastructure, and the transformation of infrastructure needs a long time and a lot of investment, but also government support.

2) 0-100km fast acceleration, 100km to 200km is not fast, because the motor in the high speed, torque output greatly reduced. Insufficient reacceleration at high speeds.

3) when the battery is affected by temperature, it will be discounted on cold days, and it will consume quickly when driving at a high speed.

odelS what kind of car are they, regardless of the electric car model?

odelS chassis suspension, air springs, aluminum body, ultra high strength steel protection, high specification tires, are all top car configurations. Interior seats are also optional.

odelS are a little like the iphone of the past, even without apple's multi-touch, IOS software. HVGA true color 3.5-inch screen, 600mhz ARM11 processor, large memory flash memory, ultra-thin body. It was all top in 2007.

re ModelS safe? Will it explode?

s things stand, the ModelS have succeeded in solving the problem of hot flash discharge with power management, and in solving the problem of battery impingement by means of layers of protection, reasonable arrangement of positions and independent isolation. There have been several incidents in which the battery has not broken down. But the long term is still to be seen.

an Chinese manufacturers make tesla ModelS ModelS in minutes?

ou can't build the full version, but you can build it with less control, less range, and more acceleration. Use heavy battery, light body, large motor can be, but practical significance is not big.
