"This time I came to Longteng Forest. On the one hand, I came to see the progress here. On the other hand, I brought my family here to relax and experience life. At the same time, I also worked a part-time job. Hey, these people really don't want me to
I'm free..."
Zhang Fan smiled and said to the camera, which made everyone laugh.
"But this job is still very interesting. The job is actually very simple, that is, being a test driver. I don't know if you have noticed the car I drove before coming here."
Zhang Fan said mysteriously, which made everyone look curious.
"Let's go take a look at this car..."
Zhang Fan said with a smile, and then the camera turned. A car appeared in the line of sight. Only then did everyone realize that the car was covered in camouflage.
"I'll go, pick up..."
"Is this a Tesla, an electric pickup truck?"
"This head is quite big, comparable to that of a raptor..."
"It's very powerful..."
"I really like pickup trucks..."
When they saw this car, everyone immediately started talking. They didn't expect it to be an electric pickup truck.
"Yes, this is an electric pickup truck. The chassis is from KS."
Zhang Fan said with a smile that news about Tesla's KS, a full-size hard-core SUV, is constantly breaking out. It is planned to be officially launched at the end of next year.
This pickup truck is equivalent to the KS with the back open. However, it has been specially optimized and turned into such a highly functional pickup truck.
"This car is a test car, and its data is basically the same as that of KS. The car is nearly six meters long and about the same size as Ford's Raptor. It uses pure electric drive, electric four-wheel drive, four newly developed permanent magnet motors, and the largest
It can produce 650 horsepower, and the most important thing is that the maximum torque can produce 2,000 N."
Zhang Fan started to introduce this car, and everyone swallowed their saliva after hearing these data.
650 horsepower and a maximum torque of 2,000 Nm. This data is really scary.
"According to different driving modes, different power outputs can be achieved. In this regard, the advantages of electric motors are much stronger than engines. So if you look at the more advanced ships now, they all use pure electric drive."
Zhang Fan said seriously. Compared with fuel engines, electric motors have great advantages because they are easier to adjust and relatively accurate.
Through the entire system, the torque can be adjusted and the speed can also be adjusted. This intelligent adjustment has a complete system for conversion.
Especially on this car, the control system will automatically adjust the car's situation based on comprehensive factors such as terrain and load capacity, so that the car can enter the best state at the fastest speed.
Although it is a pickup truck, it incorporates Tesla's most advanced technologies.
"This pickup truck is currently the most technologically advanced vehicle in our Tesla Group. It uses a new permanent magnet motor, a new generation of electronic control system, and a new generation of intelligent driving system. If there are no accidents, this car will be launched next year.
Sometimes, it will also be equipped with the latest battery..."
Zhang Fan said mysteriously, which made everyone's eyes light up.
"I'll go, no. The new battery..."
"Could it be a graphene battery..."
"It would be awesome if it were graphene..."
"Solid-state batteries are also awesome..."
Looking at everyone's discussion, Zhang Fan laughed mysteriously. With regard to the new battery, Tesla's team has already made a breakthrough.
This breakthrough is not a graphene battery, but a solid-state lithium battery. Although graphene battery technology has made progress, it is still far from being truly practical. After all, graphene batteries are too unbelievable.
Solid-state lithium batteries have made quite a breakthrough. Compared with liquid lithium batteries, new solid-state lithium batteries have many advantages.
The first point is lightness. Solid-state lithium batteries use all-solid electrolytes. After using this electrolyte, the applicable material system of lithium-ion batteries will also change.
The core point is that it is not necessary to use lithium-embedded graphite negative electrodes, but to directly use metallic lithium as the negative electrode. This can significantly reduce the amount of negative electrode material, so at the same density, solid-state lithium batteries are lighter.
The second point is thinness. Traditional lithium-ion batteries require the use of separators and electrolytes, which together account for nearly 40% of the volume and 25% of the mass of the battery. Now replaced by solid electrolytes, the distance between the positive and negative electrodes
It can be shortened to only a few to a dozen microns, so that the thickness of the battery can be greatly reduced. In this way, the all-solid-state battery can be miniaturized and the thin film is gorgeous. In the future, the battery may be just a film.
The third point is flexibility. The flexibility of all-solid-state batteries will be significantly improved after they are made thinner and lighter. By using appropriate packaging materials, the batteries can withstand hundreds to thousands of bends without attenuating performance.
Fourth, it is safer. When traditional lithium batteries operate under high current, lithium dendrites may appear, which may pierce the diaphragm and cause short-circuit damage. At the same time, the internal electrolyte is an organic liquid, which undergoes side reactions at high temperatures, oxidizes and decomposes, and generates gas.
The tendency of combustion will be aggravated. Using all-solid-state battery technology, these can be directly solved.
So taken together, the advantages of solid-state batteries are too obvious. Currently, many companies are also studying solid-state battery technology, but the investment is relatively small.
But Tesla's investment in this area is very large, plus the technical data exchanged by Zhang Fan and the people poached with a lot of money.
Now solid-state batteries have made quite a breakthrough. Although it is only an initial technological breakthrough and cannot achieve thin film or miniaturization, the advantages have been shown.
Compared with the batteries currently used by Tesla, the weight of the solid-state lithium battery is 40% lighter and the energy is increased by 30% for a battery pack of the same size.
This is a terrible improvement, which shows that if a car uses a new solid-state battery, the weight of the car will be greatly reduced, and the battery energy will be greatly increased.
As the weight of the vehicle is reduced, the power consumption is reduced, and the cruising range is naturally increased.
For example, current Tesla, taking MODEL 6 as an example, if the battery pack inside is replaced by a solid-state battery, the comprehensive cruising range will increase by about 40%.
Such an increase is terrible. The basic version of 500 kilometers can directly increase the cruising range by 200 kilometers, reaching 700 kilometers.
As for the 700-kilometer version, the cruising range can basically reach 1,000 kilometers.
This incredible data can completely blow away traditional fuel vehicles.
It can even set itself apart from other car companies by a long way. This kind of battery technology is really amazing.
However, Tesla's models will not be equipped with this battery in a short period of time. Compared with traditional battery packs, the cost of solid-state batteries is much higher.
A car company needs to consider costs. The reason why this battery will be first installed on KS and pickup trucks in the future is because these things are toys for rich people.
The full-size SUV KS is a Big Mac, so the price is naturally high, and the R version will be even higher. In the future, the new battery will only be installed on the R version, so it doesn’t matter if the battery cost is higher, because the car will make more money.
