Super Weapon Swap System

When the car just appeared, there were all kinds of power, including steam engine, internal combustion engine and battery car. Yes, it's like an old scooter.

In the early days, a few lead-acid batteries were enough to drive a car. This method seemed good. In fact, there were pits everywhere. The main reason was that the endurance was too poor. At that time, the storage energy of the battery was very little. If you went out for a walk, you would have no electricity. After the emergence of the gasoline engine, you immediately had incomparable advantages, It has become a pastry in the eyes of various automobile experts. After that, it has been continuously developed and developed around the internal combustion engine until now.

Now, the trend of electric vehicles has gradually begun.

Just last year, general motors first took action. They developed an electric vehicle code named EV-1 and put it on the market.

This is the pioneering work of electric vehicle, but it has no other choice. It uses lead-acid battery. Yes, it is the same lead-acid battery as the elderly scooter, which leads to the low range of this electric vehicle, only 140km. This is still the most ideal situation. The maximum speed is less than 80km / h, and, If you drive at this top speed, you will consume all the electric energy in a short time.

These performances have reduced it to chicken ribs. Therefore, after spending a lot of money on R & D, few people buy it in the market. This is the most speechless ending.

One of the engineers who developed the car, coco Ni, left GM and began to create his own electric vehicle company, hoping to develop qualified electric vehicles. However, his strength was too small, so he found alberthard, an engineer in Silicon Valley. When they were discussing the plan, musk took the initiative to come to the door.

When musk was in college, he realized that the automobile will usher in a revolution, which is new energy and environmental protection. The exhaust of gasoline vehicles will pollute the environment, but electric vehicles don't have this disadvantage. Moreover, in the future, the concept of environmental protection will be more and more popular. Look at the current Han state, which has begun to layout in advance.

They continue to issue strict automobile exhaust emission standards and then upgrade their own industry. In order to follow this pace, Western automobile factories have begun to purchase necessary parts from the Han country. Otherwise, they can only research and develop by themselves and avoid patent barriers, which makes them difficult.

Moreover, recently, the Han people have put forward a new scheme to reduce fuel consumption in the automotive industry, that is, hybrid power. They upgrade the car's power system to 48 volts, and then have the participation of motors in car starting, braking recovery, cruise, etc., so as to greatly improve efficiency and reduce energy consumption.

"The future era will be the world of electric vehicles." Musk began his own lobbying. They just have this idea and belief. However, to put this idea into reality, it requires huge capital investment.

They need financing, and they even need several rounds of financing. At this time, they must find a large company to endorse. No matter from which perspective, apple is the most appropriate.

"Electric vehicles are pollution-free and the most environmentally friendly," Musk said "We have seen that this trend is coming. In the field of traditional internal combustion engines, we have fallen behind. Our vehicles have high fuel consumption and high emissions. Many technologies are in the hands of foreign countries, which is also the main reason why GM finally falls into the brink of bankruptcy. Therefore, we might as well develop in the field of electric vehicles from now on and finally realize the corner Overtake and stand at the peak of the times. "

When it comes to this, Musk's eyes are full of longing: "we look forward to the arrival of that era, and we also look forward to our step-by-step going to that era."

Jobs listened carefully to each other's introduction, and then said with doubts: "what does this have to do with me? We are making electronic products, not cars."

"The future electric vehicle is an electronic product," Musk said "Steve Jobs, you still don't understand my idea. We need to build cars through the Internet. We don't need traditional sales channels to build cars through the model of electronic companies. Every car we have is ordered, configured and produced on the Internet. Our cars will enter the high-end market."

"However, it is not destined to be an electronic product. In particular, the problem of its endurance can not be solved," Jobs said. He pointed out that the biggest problem of electric vehicles is cruising power.

General Motors has failed. Their electric vehicles are short legged goods, and there is almost no solution.

If you want to increase the cruising force, you have to increase the proficiency of the battery. However, the lead-acid battery is too heavy. If you continue to increase the number of lead-acid batteries, you will greatly increase the overall weight of the car, then increase the resistance, and finally offset the increased electric energy.

Therefore, the maximum endurance mileage has a ceiling, which can not be broken through at all unless it is solved with new technology. However, at present, it seems that there is no technological innovation of lead-acid battery. You know, no matter how the innovation is, it is lead-acid battery! Lead ah, sulfuric acid ah, it is quite dense.

"That's why we came to you," Musk continued. "After careful research, we decided to use the lithium battery of notebook computer as the solution."

what?

Hearing this, jobs opened his mouth: "are you kidding?"

The endurance of apple notebook is unmatched by other notebooks. On the one hand, it has excellent battery management ability. On the other hand, it has the most advanced lithium-ion batteries from Han. When other manufacturers are still using nickel cadmium batteries, Han has developed generations of advanced lithium-ion batteries without memory effect, With large capacity, it can almost meet the needs of users in one day.

However, lithium-ion battery also has disadvantages. It is easy to heat. If it is not managed well, it may explode. You know, lithium is a very active element in the periodic table. You must be careful when storing it.

In the apple notebook, there are at most six cell batteries, that is, there are six lithium-ion batteries, which has tested the design skills of engineers. If it is an electric car? Do you have to put thousands of knots in it?
