Tesla Shifted Their Attention to Ultracapacitor: What's the Indication?

Long before Tesla was even a glint in Elon Musk's eye, he was exploring ultracapacitors at Stanford University. It seems that Musk is still excited about the technology. Well, he does. About three years ago, Tesla announced its plan to acquire Maxwell Technologies, a leading enterprise in the energy storage industry that is famous for its supercapacitor technologies. 

We can see why his interest is developing; ultracapacitors have already been utilized in some electric vehicles to store fast available energy thanks to their high-power density. An ultracapacitor is ideal for electric vehicles as it maintains batteries below safe resistive heating limits and helps them last longer. In the text below, let us elaborate a little more on ultracapacitor technology and ultracapacitor car.

Types & Components of A ultracapacitor

These ultracapacitors come in three types, which are:

●Double-layer capacitor

●Pseudo capacitor

●hybrid capacitor

A double-layer capacitor is made of two electrodes, a separator, and an electrolyte, whereas electrodes, conductive polymers, or metal oxide are used in pseudo-capacitors. The quantity of electric charge held in a pseudo-capacitor is proportional to the voltage supplied. 

Hybrid capacitors are created by combining techniques from double-layer capacitors and pseudo-capacitors. Both double-layer capacitance and pseudo-capacitance are employed in hybrid capacitors. Electric cars, in particular, majorly use hybrid capacitor models due to the ultracapacitor energy storage capacity.

Benefits of ultracapacitors to Electric Vehicles

Due to the higher power density than chemical reaction-based batteries, the ultracapacitor in electric cars allows them to store and discharge electricity more quickly, which is useful for storing energy during braking and fast releasing it during acceleration.

Ultracapacitors are widely used in the automotive industry as 

• Normally, they can store 10 to 100 times more energy per unit volume or mass than electrolytic capacitors.
• Accept and deliver charge much faster than batteries
• Can withstand many more charge and discharge cycles than rechargeable batteries.
• Great adaptability to extreme temperatures.

Recommendation of Ultracapacitors

Compared to the present dominant liquid electrode (electrode material mixed with solvent) technology, dry electrode technology made of nanostructured carbon-based materials can increase the energy density of the battery system.

Many ultracapacitor manufacturers like Beryl are crafting superpower sources to deliver auxiliary power in a way to cater to the growing needs of the self-driving industry. These ultracapacitors are designed for high-power and high-cycle applications, ensuring a smooth and uninterrupted driving experience, and features such as:

●Fast Charging and Discharge Times, Effectively Unlimited Cycle Life

The fast charging and low discharge time give ultracapacitors unlimited life, and the low discharge feature of the ultracapacitor automatically improves the life cycle of the battery of electric cars since they don't degrade in the same fashion as lithium-ion batteries.

●High Power Density

Beryl uses dry electrode technology to boost the energy density of ultracapacitors. Because of the high-power density of ultracapacitors, more power can be processed in a smaller space, ultimately improving system functionality while lowering overall system cost. Besides, they also charge faster than batteries and are highly reliable for short-term mismatches between power demand and power availability.

●Long service life and predicable aging

The average lifespan of ultracapacitors is 12 years (working under normal operating conditions). This largely accounts for its great capability in adapting to harsh environments, like extreme weather ranging from –40°C to 65°C, and its impressive typical cycle life of 500,000 to 1 million charge/discharge cycles.

●Pollution-Free and Cost-Effective

Ultracapacitors are found to be a more environmentally friendly and pollution-free energy source than traditional lithium batteries. In addition, it does not require heating or cooling costs, which will save a lot.

Ending Note

Given Tesla's shifted attention to ultracapacitor technology, it is highly probable that it could be the next part of Musk's electric vehicle. There's no doubt that the future of electric vehicles is here, and we will soon witness ultracapacitor charging stations and wireless charging pads powered by them.

Considering this, many EV developers are looking for manufacturers who can provide high capacity, high-temperature resistant, and leakage-proof technology. One of the highly recommended by the industry is Beryl, a leading ultracapacitor producer devoted to meeting the demands of tech-savvy EV developers. The Beryl ultracapacitor has many benefits for its end customers.
