Revolutionary Charging Speeds and Longevity

Nyobolt's new EV prototype, developed in collaboration with engineering firm CALLUM, promises to transform the electric vehicle landscape. Initial tests using a 350kW DC charger have shown that Nyobolt’s batteries can charge from 10% to 80% in under five minutes. This is twice as fast as the quickest charging vehicles currently available, and without the degradation issues often seen in lithium-ion batteries.

Dr Sai Shivareddy, Nyobolt’s co-founder and CEO, highlights the significance of this breakthrough: “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.”

Extensive Testing and Real-World Validation

Independent testing by a leading global OEM has confirmed that Nyobolt’s batteries maintain over 80% capacity even after 4,000 fast charge cycles, equivalent to 600,000 miles. The prototype’s 50Ah 35kWh battery achieved a 10% to 80% charge in just four minutes and 37 seconds during initial in-vehicle tests, providing a range of 155 WLTP miles. This rapid charging capability provides 120 miles of range after just four minutes of charging.

Shane Davies, Nyobolt’s Director of Vehicle Battery Systems, states, “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.”

Sustainable and Scalable Battery Production

Nyobolt’s technology leverages patented carbon and metal oxide anode materials, innovative cell design, integrated power electronics, and software controls to create power-dense battery and charging systems. These systems support high-uptime industrial and automotive applications, including heavy-duty off-highway trucks, EVs, robotics, and consumer devices.

The company is preparing for low-volume production of their battery systems, with plans to ramp up to 1,000 packs by 2025. Nyobolt’s flexible manufacturing model can support volumes of up to two million cells per year, ensuring scalability and compliance with the EU’s Battery Regulation requirements.

Enabling High-Performance and Lightweight EVs

The Nyobolt EV prototype, a sports car weighing just 1,250kg, demonstrates how their technology enables energy-efficient electric vehicles that are both cost-effective and resource-efficient. This development is crucial for the automotive industry, as it strives to produce lighter, better-handling sports cars.

“Our extensive research here in the UK and US has unlocked a novel battery technology that is ready and scalable right now,” concludes Dr Sai Shivareddy. “We are enabling the electrification of new products and services currently considered inviable or impossible. Creating real-world demonstrators, such as the Nyobolt EV, underlines both our readiness and commitment to making the industries see change is possible.”

Expanding Horizons and Future Applications

Nyobolt is already in discussions with eight OEMs about incorporating their technology into high-performance EVs. Beyond automotive applications, Nyobolt’s fast-charging technology is set to revolutionise robotics and heavy-duty commercial vehicles, offering low downtime and high productivity.
