Nyobolt trials EV prototype

Nyobolt is taking its high-power density, fast-charging battery technology into a real world application with an EV prototype. 

Designed and engineered with CALLUM, the EV will be used to validate its battery performance in a high-performance environment. 

The tech allows for 80% charging in five minutes. Founded in 2019, Cambridge-based Nyobolt has used carbon and metal oxide anode materials, low impedance cell design, integrated power electronics and software controls to create power dense battery and charging systems. 

Nyobolt’s technology also stops degradation, it claims, with its 24.5Ah cells have already successfully completed over 4,000 full DoD (Depth of Discharge) fast charge cycles, equating to over 600,000 miles. 

Independent OEM testing has confirmed its 2.6Ah cells can achieve over 4,400 cycles with a 12C charge and 1C discharge at 23°C. 

Nyobolt’s co-founder and CEO, Dr Sai Shivareddy said:

“Despite some OEMs showing fast charge times in the region of 15 minutes, a closer inspection reveals the charge is usually across a limited SOC region specifically chosen to limit the amount of life taken out of the cell; for instance, between 20-80 per cent. 

“Typically, the charge profile will only hold these peak charge levels for a short amount of the charge time. Nyobolt’s low impedance cells ensure we can offer sustainability, stretching out the battery’s usable life for up to 600,000 miles in the case of our technology demonstrator.”

In addition, the 35kWh battery pack in the Nyobolt EV prototype is just 1,250kg. 

Shane Davies, Nyobolt’s director of vehicle battery systems, said:

“We can enable OEMs to build excitement back into the segment, which is literally weighed down by legacy battery technology currently,” says

“Our Nyobolt EV demonstrates the efficiency gains facilitated by our fast-charging, longer-life battery technology, enabling capacity to be right-sized while still delivering the required performance.

“Nyobolt is removing the obstacle of slow and inconvenient charging, making electrification appealing and accessible to those who don’t have the time for lengthy charging times or space for a home charger.”
