Lamborghini and MIT announced collaboration with Lamborghini and Super EV "Telzo Millennio" which does not require battery by charging the car itself

Concept model of an electric supercar that collaboration between Italian super car maker Lamborghini and Massachusetts Institute of Technology (MIT), one of the world's most prestigious schools "Terzo Millenio"Was announced. This model, named "Japanese Third Millennium", is equipped with a function to self-repair a wound by using carbon nanotube material, and at the same time a "super capacitor" capable of charging the entire body and By doing so, it makes the battery unnecessary, it aims to realize weight saving and space saving required for super sports.

Lamborghini Terzo Millennio (Lamborghini · Terzo · Millenio)


Terzo · Millenio has a form that is low and delivers the atmosphere of "super car" indeed. It is an EV super car which runs with an in-wheel motor built into four tires without mounting the engine by the conventional internal combustion engine.


When viewed from the side, design that releases a different future feel while letting Lamborghini feel like. This body made of carbon nanotubes has the function of self-diagnosing and repairing scratches, and Lamborghini and MIT have a vision of using this body itself as a battery.


The concept targeted by this concept model is "a sports car of the future". In this era the world there is a flow to shift to the EV, Lamborghini has defined the elements to achieve without compromising the EV supercar (Super EV) from the viewpoint of "innovation material" and "energy storage".

By adopting carbon nanotube, one of the cutting-edge materials in the material of the body, Terzo Millenio makes it possible to carry out the entire bodySuper capacitorUsed as. Supercapacitor has the ability to charge and discharge strong electric energy at a stroke, so it can be said to be an energy source suitable for Super EV equipped with high power motor.


One problem that EV has is that it can not escape from the weight and volume of the battery. EV's performance has evolved at a stroke in the 2000's, but it has not been able to escape from the fate of saying "I have to install a heavy and large battery". This is an inevitable problem even with lithium ion batteries that are said to be lightweight and compact with high energy density, and most of the EVs that are already on the market are equipped with a battery with hundreds of kilograms on the car body. As an example, Nisan Reef has about 300 kg, and Tesla Model S has more than 700 kg lithium-ion battery.

By loading a heavy battery, the driving performance of the car itself will also have a big impact. By having to move a heavy car body, "electricity cost" indicating the distance that can run with one charge will worsen, and it will be inevitable that the motor performance during acceleration, braking and cornering will also be adversely affected. Therefore, although each company has devised to minimize the influence, such as spreading the battery under the floor of the car body, there is no way to make the physically increased mass pears so far.

Indeed, it is impossible to neglect the motor performance as it becomes a super car. Therefore, Lamborghini and MIT are aiming to solve the problem of weight and volume by throwing away the batteries which are heavy and bulky and using the car itself as a supercapacitor. Supercapacitor can be said to be a large-scale version of the electronic component "capacitor" and has the ability to perform charging and discharging rapidly.

One lithium ion battery has lower charge / discharge capability than a super capacitor, and heat generation occurs when a large amount of current flows. Furthermore, this heat generation leads to deterioration of battery performance and also leads to safety problems, so even though it has the best performance in modern times, it is far from being perfect as an energy source for high-performance EV It is obliged to say.

In this way, although it is a super capacitor that seems perfect for a high power super EV, in reality there is a big problem of "very small storage capacity". Therefore, even if you can demonstrate high power, that time will be very short.

However, Lamborghini and MIT are showing a positive attitude towards the future of supercapacitors. Mauricio Legiani, Director of Research and Development at Lamborghini, said, "At this stage, we are very optimistic," even though it takes years for research and development, this direction It shows the view that sex is worth going forward.


At the present moment, supercapacitors or capacitors with small capacities are installed in commercial vehicles, but its use is about the power source of the motor when starting the engine and the power source of the electric components. Also, since supercapacitor has characteristic that voltage drops during discharging, high technology is required to stably supply large electric power enough to move the car body.

Lamborghini and MIT seem to recognize that it will take time to put it into practical use, but it seems to be an important technology to open up the future of automobiles in the future, so I'd like to watch the trend of future development.


In addition, attention is gaining attention as an energy source of EV, "Toyota and Tokyo Institute of Technology develop"All solid state battery"is. Toyota has been sending hybrid vehicles such as Prius and plug-in hybrid cars to the world, but it is also seen that all-solid-state batteries will put off an attack of enlarging EV at a stroke as they enter the practical stage, I can not get it away.
