"This time I came to Longteng Forest, on the one hand, to see the progress here. On the other hand, I also bring my family here to relax and experience life. At the same time, I also have a part-time job, hey, these people really don't want me to be idle......"

Zhang Fan smiled at the camera and said, which made everyone laugh.

"But it's still a lot of fun. The job is actually very simple, and that is a test driver. I don't know if you noticed the car I was driving before I came. ”

Zhang Fan said mysteriously, which made everyone curious.

"Let's go see this car......"

Zhang Fan said with a smile, and then the camera turned. A car appeared in sight, and at this time everyone realized that the car was cloaked in camouflage.

"I'll go, pickup ......"

"Is this Tesla, an electric pickup?"

"This head is quite big, and it has a ...... with a bird of prey."

"It's mighty......"

"I like pickup trucks......"

Seeing this car, everyone immediately started talking. They didn't expect it to be an electric pickup truck.

"Yes, it's an electric pickup. The chassis is the chassis of the KS. ”

Zhang Fan said with a smile that Tesla's KS, a full-size hard-core SUV, has also been breaking news about this car. It is scheduled to be officially launched by the end of next year.

And this pickup truck is equivalent to KS opening the back. However, it has been specially optimized to become such a highly functional pickup truck.

"This car is a test car, and the data is basically the same as that of the KS. The car is nearly six meters long and is about the size of a Ford Raptor. It adopts pure electric drive, electric four-wheel drive, and four newly developed permanent magnet motors, which can burst out a maximum of 650 horsepower, and most importantly, a maximum torque of 2000 Nm. ”

Zhang Fan began to introduce the car, and everyone swallowed when they heard the data.

With 650 hp and 2,000 Nm of torque, that's a pretty scary figure.

"Depending on the driving mode, there can be different power outputs. In this regard, the advantages of the electric motor are much stronger than the engine. So you see that the more advanced ships now are all powered by pure electric drive. ”

Zhang Fan said seriously. Compared with the fuel engine, the motor has a great advantage. Because it is relatively easy to adjust and relatively precise.

With the complete system, the torque can be adjusted and the speed can also be adjusted. This intelligent adjustment has a whole system to make the conversion.

Especially on this car, the control system will be based on a combination of reasons such as terrain, load capacity, etc. Automatically adjust the condition of the car, 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 technology.

"This pickup truck is currently the most high-tech car in our Tesla Group. Using a new permanent magnet motor, a new generation of electronic control system, a new generation of intelligent driving system, if there is no accident, next year when this car is on the market, it will also be equipped with the latest battery ......"

Zhang Fan said mysteriously, and his words made everyone's eyes light up.

"I'll go, no. New battery ......"

"Is it graphene battery ......?"

"If graphene is awesome......"

"Solid-state batteries are also awesome......"

Looking at everyone's discussions, Zhang Fan smiled mysteriously. New battery, the current Tesla team has made a breakthrough.

This breakthrough is not graphene batteries, but solid-state lithium batteries. Although graphene battery technology has made progress, it is still far from being truly practical, after all, graphene batteries are too rebellious.

However, solid-state lithium batteries have made a big breakthrough, compared with liquid lithium batteries. The new solid-state lithium battery has many advantages.

The first point is lightness, solid-state lithium batteries use an all-solid-state electrolyte, and after the use of this electrolyte, the applicable material system of lithium-ion batteries will also change.

One of the core points is that it is not necessary to use the graphite anode embedded in the lithium, but directly use lithium metal as the anode, which can significantly reduce the amount of anode material, so under the same density, the solid-state lithium battery is lighter.

The second point is thinness, in traditional lithium-ion batteries, separators and electrolytes need to be used, which together occupy nearly 40% of the volume and 25% of the mass of the battery. Now replaced by a solid-state electrolyte, the distance between the positive and negative electrodes can be reduced to even a few to a dozen microns, so that the thickness of the battery can be greatly reduced. In this way, all-solid-state batteries can be miniaturized and thin-filmed. In the future, maybe the battery will be a film.

The third point is flexibility, the flexibility of all-solid-state batteries will also be significantly improved after thinning, and by using appropriate packaging materials, the batteries made can withstand hundreds to thousands of bends to ensure that the performance is basically not attenuated.

Fourth, it is safer, traditional lithium batteries work under high current, lithium dendrites may appear, which will puncture the separator and cause short circuit damage. At the same time, the internal electrolyte is an organic liquid, and the tendency of side reactions, oxidative decomposition, gas production, and combustion will be aggravated at high temperatures. With all-solid-state battery technology, these can be solved directly.

So all in all, the advantages of solid-state batteries are too obvious. Many companies are also working on solid-state battery technology, but the investment is relatively small.

However, Tesla's investment in this area is very large, coupled with the technical information exchanged by Zhang Fan and the people who dug it up.

Now solid-state batteries have made quite a breakthrough. Although it is only an initial technological breakthrough, it cannot achieve film Hua and miniaturization, but the advantages have been shown.

Compared to the batteries used by Tesla, the battery pack of the same volume. Solid-state lithium batteries are 40 percent lighter and 30 percent more energy-efficient.

That's a terrible increase, which shows if a car uses a new solid-state battery. The weight of the vehicle will be greatly reduced, and the battery energy will be greatly increased.

When the weight of the vehicle is reduced, the power consumption is reduced, and the cruising range is naturally increased.

FOR EXAMPLE, IF THE CURRENT TESLA TAKES THE MODEL 6 AS AN EXAMPLE, IF THE BATTERY PACK INSIDE IS REPLACED WITH A SOLID-STATE BATTERY, THE COMPREHENSIVE RANGE WILL INCREASE BY ABOUT 40%.

Such an increase is terrible, and the basic version of 500 km can directly increase the cruising range by 200 km, reaching 700 km.

In the 700 km version, the cruising range can basically reach 1000 km.

This anti-natural data can completely throw off traditional fuel vehicles.

It can throw other car companies away a lot, and such battery technology is indeed too powerful.

However, in the short term, Tesla's models will not be equipped with this battery. Because compared to traditional battery packs, the cost of solid-state batteries is much, much higher.

As a car company, you need to consider the cost. The reason why this battery will be the first to be installed on KS and pickup trucks in the future is because these things are toys for rich people.

Full-size SUVks, that is, a jumbo, the price is naturally high, and the R version is 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 high, because the car makes more money.
