CALLUM & Nyobolt reveal EV sports car set for six-minute charge

Design and engineering business CALLUM, together with pioneering developer of ultra-fast-charging batteries, Nyobolt, have today revealed the Nyobolt EV.

Designed by Julian Thomson, developed and executed by CALLUM together with Nyobolt, it is set to feature Nyobolt’s new advanced battery technology that can charge fully in less than six minutes.

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.”

Nyobolt, wishing to demonstrate this ultra-fast charging battery technology in a nimble, lightweight sportscar, turned to the talents of revered car designer, Julian Thomson.

The result of this collaboration is the Nyobolt EV – a sports car with greater presence and exaggerated proportions. Sitting on 19” wheels all around, its low-slung body 100mm wider and 150mm longer than its inspiration, while maintaining an aggressive attitude and hunkered stance that’s reminiscent of the original. The wide front track quickly rolls into the body and back out again into muscular rear haunches with signature ‘duck tail’, creating an exquisite hourglass shape.

“The aim was to evolve the design and bring it up to date while keeping that iconic sports car character that was so well received in the Elise,” explains Aleck Jones, creative lead at CALLUM. “Typically, you run into feasibility issues with initial sketches and a design loses impact as it moves from concept into reality, but incredibly – and thanks to the close working relationship between CALLUM’s design and engineering teams – we have been able to realise our early images and unique vision in the real world.

“Nyobolt’s technology allows this car to tick all the boxes that made the original Elise such a desirable drivers’ car with a cult following, but it’s electric. These two things don’t usually come hand-in-hand due to weight and battery packaging constraints.”

Targeting an industry solution to charging, battery materials supply and degradation, Nyobolt reveals new battery technology that is smaller, lighter and faster to charge. In the Nyobolt EV, set to weigh close to one tonne, this translates into a 35kWh battery that is capable of fully charging in just six minutes with existing charging infrastructure, delivering a range of up to 250km. Additionally, the battery has been tested for over 2,000 fast charging cycles without significant performance loss.

Nyobolt’s ready-to-deploy technology, which will go into production in early 2024, unlocks this ‘holy grail’ through a proven 10C (six-minute) charge lithium-ion technology that is capable of immediate application and rapid scale-up. This breakthrough translates to a nimbler, more efficient EV with a lower up-front cost, lower running costs and lower use of scarce raw material.

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.”
