Established in 2019 by University of Cambridge battery scientists Professor Clare Grey CBE and Dr. Sai Shivareddy, Nyobolt collaborated with CALLUM, a British design and engineering firm, to test its fast-charging EV battery in a demanding environment.

CALLUM developed a prototype Nyobolt EV to validate the battery’s capabilities, demonstrating a remarkable ability to charge from 10% to 80% in just four minutes and 37 seconds.

This breakthrough in fast-charging technology has the potential to revolutionize the adoption of electric vehicles, addressing concerns about charging times and range anxiety among prospective EV drivers.

Unmatched Speed in EV Charging

The 50Ah 35kWh electric car battery underwent testing with robust 350kW (800V) DC fast chargers, achieving an 80% charge in slightly over four and a half minutes.

During the initial four minutes of charging at a steady current of 500A, this provides a range of 120 miles.

When fully charged, the prototype electric vehicle can cover a distance of 155 miles based on WLTP standards.

Extended Battery Lifespan

Nyobolt’s technology effectively mitigates the degradation issues typically associated with fast-charging lithium-ion batteries.

Their 24.5Ah cells have demonstrated over 4,000 full Depth of Discharge (DoD) fast charge cycles, equivalent to more than 600,000 miles in a Nyobolt EV pack while maintaining over 80% battery capacity. This performance significantly surpasses the warranties of most larger EV batteries available today.

Testing carried out independently by OEMs has confirmed that Nyobolt’s 2.6Ah cells can endure more than 4,400 cycles with a 12C charge and 1C discharge at a temperature of 23°C. Notably, the internal resistance of these cells increases by only 50% after 4,400 five-minute charge cycles, which is lower than the industry standard for end-of-life values of EV cells, typically doubling the initial resistance.

Expanding Production for Commercialization

Nyobolt is advancing its battery assembly plans with a goal to commence production at low volumes within a year and to scale up to 1,000 packs by 2025.

Their adaptable manufacturing model supports capacities of up to two million cells annually, ensuring compliance with the EU’s Battery Regulation once production begins.

Nyobolt’s EV architecture also indicates potential retrofitting to existing EV platforms, promising significant advancements in charge time and battery lifespan.

The company is actively collaborating with eight additional vehicle OEMs to integrate its technology.

Beyond automotive applications, Nyobolt’s fast-charging technology will debut this year in robotics and is positioned for use in heavy-duty commercial vehicles, reducing downtime and enhancing productivity.

This UK start-up’s technology could play a crucial role in encouraging drivers to transition to EV’s, aligned with the UK’s goal for all new cars and vans to be zero-emission by 2035.
