This is Lamborghini’s new energy car, not a pure electric car, but a hybrid car, a hybrid sports car with a 6.5-liter V12 engine, named Sián.
Sián comes from Bologna and means: a bolt of lightning.
How fast, I don’t need to say more, after all, the 6.5-liter V12 monster hangs in the back.
The maximum power can reach 819 horsepower, the top speed exceeds 350 kilometers per hour, and the 0-00 acceleration only takes 2.8 seconds.
The main power of this car is still an oil-burning hybrid car. It has a zero-to-hundred acceleration of 2.8. It is 0.7 seconds behind the Roadster with thousands of horses that Musk shouts every day but still has not mass-produced. It successfully entered the two-second club.
Nowadays, car companies around the world are waving goodbye to the era of fuel oil, and the previous super sports car brands have to transform into new energy sources.
But after all, it is a sports car brand, and even if it enters the new energy market, it has to get a “electric running” and it will be a blockbuster. Every brand is thinking about how to continue its glorious history of “speed light” in the new energy era.
Many companies choose to build pure electric sports cars. Lotus wants to build the fastest pure electric Evijia in history, as well as the upcoming Eletre. The president of Ferrari also announced that pure electric will be launched after 2025.
But Lamborghini is an outlier. It is the world’s first hybrid sports car to use a “supercapacitor”, the same 6.5-liter V12, and the Ferrari 812 GTS’s 0-00 acceleration takes 3 seconds.
The secret weapon is the Supercapacitor inside the Sián.
Look at the picture below, which is like a QQ Speed car with nitrogen to accelerate. The left side is recharge and the right side is boost, which represent charging and discharging respectively.
Yes, racing game party ecstasy. . .
When the vehicle brakes, it will quickly store energy for the supercapacitor. If you step on the accelerator, the supercapacitor will instantly release the energy stored during braking and rapidly increase the motor torque.
It’s like the start acceleration and drift acceleration in QQ Speed.
But before we talk about supercapacitors, let’s talk about capacitors.
Scientific statement:
“Two metal conductors close to each other with a non-conductive insulating medium sandwiched between them form a capacitor. When a voltage is applied between the two plates of a capacitor, the capacitor will store charge”.
To put it bluntly, you can think of a capacitor as a fast-charging and fast-discharging “battery”, but this battery can’t store electricity.
We had a lot of this stuff in the old radios we used to have. For example, bypass capacitors can make the output of the regulator uniform.
When the light on the radio flashes, that is, the current is unstable, the capacitor will stand up to stabilize the current. When the current is weak, the capacitor will discharge to make up for it. When the current is strong, it will be silently charged.
Capacitors are a good thing, but the inherent defect of low power storage restricts its “big picture”. The capacitance of traditional capacitors is related to the size of the conductor metal plate. The larger the metal plate, the more electrons can be stored, and the greater the capacitance.
However, the area of the metal plate cannot be infinitely larger. In order to allow the capacitor to store more electricity, the scientists decided to change the way of thinking.
Such as adding collector boxes on both sides of the metal plate, or developing new electrode materials (carbon aerogels, carbon nanotubes, etc.) to create this supercapacitor.
Supercapacitors can charge and discharge like batteries, and they charge extremely quickly. For the same power storage, supercapacitors can be charged in 10 seconds – 10 minutes or less, lead-acid batteries in 4 – 8 hours, and lithium batteries in 3 – 5 hours.
Moreover, this thing has a long cycle life, and the number of deep charge and discharge can reach 500,000 times or more. Lead-acid batteries and lithium-ion batteries can be fully charged and discharged only 500 and 1000 times, respectively.
The most terrible thing is that its power density is still very high. Power density refers to the ratio of output power to volume. To put it bluntly, a supercapacitor is a small cannon. The energy ratio of the supercapacitor can reach 10KW/kg, and the lead-acid next door is only 0.02KW/kg.
It is simply a Saitama with agility, attack, and defense all full.
But this “Saitama” has a fatal flaw. The blood is thin, or rather it is not persistent. It has strong instantaneous burst ability, but if you talk about battery life, it is still a weak chicken, which also limits its large-scale use.
Therefore, when Lamborghini CTO and MIT set up this project, they said that the focus of electric Lamborghini is different from that of most other passenger cars, “I would rather fast charge than long distance”.
That’s what your Lamborghini dares to say.
So who developed and designed the supercapacitor in this game world? You can’t do it with the rough guy Lamborghini alone.
So Lamborghini found MIT (Massachusetts Institute of Technology), and Dou Jinhu (second from left), a Ph.D. from Peking University, who is currently a distinguished researcher at the School of Materials Science and Engineering, Peking University.
During the cooperation with Lamborghini, Dou Jinhu has published two first-author papers and one key patent. They used nickel benzene hexathiolate (Ni-BHT) as a new electrode material to create a Supercapacitor supercapacitor from scratch.
The supercapacitors they developed using new materials have about 3 times higher power than lithium-ion batteries under the same weight. And it only took about three years to put this basic research and innovative material on the car in one step.
Lamborghini + MIT + Peking University, the buff stack is really strong. . .
But you said that supercapacitors are really used in civilian vehicles, and it may take a long time to test. But there is no doubt that this thing may become another technological innovation in the energy industry if it is done well.
Moreover, with the widespread use of lithium-ion batteries in recent years, the safety and environmental pollution problems it brings have also caused everyone to worry, so almost zero-pollution supercapacitors are expected to replace lithium batteries.
At the national level, scientists are also encouraged to carry out related research on supercapacitors. In 2017, the Ministry of Science and Technology also officially included “large-capacity energy storage systems and applications based on supercapacitors” in the national key basic research and development plan (referred to as “973 plan”).
The above-mentioned Dr. Dou Jinhu, after completing his postdoctoral research in inorganic chemistry at MIT, also resolutely chose to return to China to join Peking University to carry out research on “multi-scale precise regulation of functional coordination polymer materials”.
To sum up, the supercapacitor has a promising future.
At the end of the article, everyone who wants to buy this car is estimated to be late. The Lamborghini Sián sold for 25.52 million, and the world is limited to 63 vehicles.
It’s not that everyone can’t come up with more than 20 million yuan, but this car has been booked before its official debut, so it didn’t give you a chance at all.
But fortunately, the poor reviewer recently got a car. So let’s stop chatting, and I’ll go “pool” a car.
