How Nyobolt’s 250km 35kWh EV Battery Charges in 6 Minutes

Nyobolt is a UK-based developer of unique ultra-fast-charging batteries.

Today Nyobolt demonstrated an EV using its battery can complete repeated full charges in less than 6 minutes. Most EVs will take at least 18 minutes from 10 to 80%, slowing down for the remainder of the charge. Not only that, continued use of ultra fast charging shortens the life of the very expensive battery pack. If the claims are true, Ev and home storage is in for a shakeup.

A vision for the future of EVs
Nyobolt’s vision is to resolve the core problems at the heart of the EV industry that are hindering the widespread adoption of electric cars globally, cost, size, degradation, and speed of charge. While this isn’t such a huge issue for home batteries, it is a massive barrier for EVs.

Id we had to pick two main barriers to the uptake of EVs, charging infrastructure, and the batteries themselves are at the core. So far, matching the current convenience of petrol refuelling has been merely a dream. Not only that, EV batteries are big, heavy, and cost a bomb, putting them out of reach of most buyers. Not only that, they do all this while managing to weigh two tonnes plus once glued to a full-sized SUV or sedan.

The need for these big heavy EV battery also makes a huge drain on resources. Nyobolt’s claim is that their new battery is smaller, lighter and takes six minutes to charge to a range of up to 250 km. This claimed breakthrough means EVs will be lighter, cheaper and will cost less to run.

Nyobolt equipped EVs will be closer to one tonne than two, with a 35kWh battery gaining 250km in under 6 mins using existing charging infrastructure. Of course, chargers are another problem altogether.

New batteries equal new design possibilities
Nyobolt tested batteries on more than 2,000 fast charge cycles without significant degredation, meaning ultra-efficient, lightweight EVs.

Expanding the idea further, larger packs used in luxury EV, truck or buses could also be charged in a few minutes, once 1MW chargers become available.

Partnership with CALLUM and renowned designer Julian Thomson
When considering a car that illustrated the benefit of fast charging and higher uptime, Nyobolt decided to work with renowned designer Julian Thomson, who was inspired by his design of the Lotus Elise, perhaps the epitome of nimble, lightweight sportscars. The design vision was to evolve it into a car with even greater presence and exaggerated proportions – making it wider, longer, lower – while maintaining an aggressive attitude and hunkered, bold stance that’s reminiscent of the original.

As a friend of the brand, Thomson invited design and engineering business CALLUM to collaborate in the development of the design and in bringing it to life. The resulting EV showcases how Nyobolt’s revolutionary battery technology can be readily adopted across the automotive industry.

With CALLUM and Nyobolt working hand-in-hand, a system-level approach has addressed each element from materials, to cell, to pack, to drivetrain, to whole vehicle. The final collaborative design therefore reflects the original vehicle’s premise of a high power-to-weight ratio within an exquisite package.

Ready to go
Nyobolt’s technology will go into production in early 2024, with 10C (six-minute) charge lithium-ion technology that is capable of immediate application and rapid scale-up. At least this is what is coming from Nyobolt HQ, so the next few years should be interesting.

Sai Shivareddy, CEO at Nyobolt, said: “Unlocking the challenges faced by electric vehicle designers has been key to the development of our breakthrough fast-charging batteries. Previously, enabling a light weight fast-charging vehicle was not possible without compromising its lifetime and so people have been relying on costly and large battery packs in the vehicle. With our unique technology we have achieved a six-minute charge car, and developed smaller battery packs that can deliver more power and charge in less time.

“Our partnership with CALLUM shows how adoption of system-level technology innovations can transform the future of electric vehicles and increase accessibility of EVs, including to the 40% of UK households who can’t charge their vehicle at home overnight ².”

David Fairbairn, managing director at CALLUM, said: “Nyobolt’s pioneering battery technology has provided us with a unique and inspiring opportunity to support in the design and execution of a vehicle set to mark the way forward for EV technology. The collaborative creativity, engineering capabilities and steadfast efforts of Nyobolt, Julian Thomson and CALLUM have resulted in an EV that is not only exciting technically for the industry, but something that is beautiful to behold, too.”
