Nyobolt tests electric vehicle prototype – transport and energy

Posted on by darion

Nyobolt is putting its high-power-density, fast-charging battery technology into practice by building a prototype electric vehicle.

Designed and engineered in collaboration with CALLUM, the electric vehicle will be used to test battery performance in a high-performance environment.

This technology allows you to charge up to 80% in five minutes. Founded in 2019, Cambridge-based Nyobolt used carbon and metal oxide anode materials, low-impedance cell design, integrated power electronics and software control to create high-power-density batteries and charging systems.

Nyobolt claims that the technology also prevents degradation – its 24.5 Ah cells have already successfully undergone over 4,000 full DoD (depth of discharge) fast charge cycles, equivalent to over 600,000 miles.

Independent OEM testing has confirmed that 2.6Ah cells can withstand more than 4,400 cycles at 12°C charge and 1°C discharge at 23°C.

Nyobolt Co-Founder and CEO Dr. Sai Shivareddy said:

“Although some OEMs claim fast charge times of around 15 minutes, closer inspection reveals that charging is typically taking place within a limited region of the SOC, specifically chosen to limit cell life; for example, between 20 and 80 percent.

“Typically, a charging profile only maintains peak charge levels for a short charging period. Low impedance Nyobolt cells ensure sustainability, extending battery life up to 600,000 miles for our technology demonstrator.

Additionally, the 35 kWh battery pack in the Nyobolt EV prototype weighs just 1,250 kg.

Shane Davies, Vehicle Battery Systems Director at Nyobolt, said:

“We can enable OEMs to re-ignite enthusiasm in a segment that is currently literally burdened with outdated battery technology,” he says.

“Our Nyobolt EV demonstrates the efficiency gains achieved with our longer-life, fast-charging battery technology, which enables us to tailor capacity to the right size while still delivering the required performance.

“Nyobolt removes the obstacle of slow and inconvenient charging, making electrification attractive and accessible to those who don’t have the time for a long charge or the space for a home charger.”
