Revolutionising Electric Vehicles: Nyobolt Unveils High-Speed Charging EV Prototype
Nyobolt is launching its groundbreaking high-power density, fast-charging battery technology into the market with the unveiling of its first operational electric vehicle (EV) prototype. Developed in collaboration with CALLUM, the Nyobolt EV aims to demonstrate the exceptional performance of the company’s batteries in high-demand scenarios and allows car manufacturers to experience a new level of customer satisfaction by eliminating the inconvenience of long charging times.
Established in 2019 in Cambridge, Nyobolt has developed cutting-edge batteries using patented carbon and metal oxide anode materials, an innovative low-impedance cell design, and integrated power electronics and software controls. These advancements support the electrification of industries and applications that require robust, high-uptime solutions, such as heavy-duty vehicles, EVs, robotics, and consumer electronics that necessitate rapid recharging.
Recent tests show that Nyobolt's 50Ah 35kWh battery charges from 10% to 80% in just four minutes and 37 seconds using a powerful 350kW (800V) DC fast charger. A full charge provides the prototype with a 155-mile range as per the WLTP standard—doubling the charging speed of today’s fastest charging EVs. Moreover, the first four minutes of charging at a constant current of 500A deliver an impressive 120 miles of range.
Nyobolt's batteries also tackle the typical degradation issues associated with rapid charging of lithium-ion batteries. The company's 24.5Ah cells have completed over 4,000 full Depth of Discharge (DoD) fast charge cycles, potentially covering more than 600,000 miles and still retaining over 80% of their capacity—significantly exceeding the lifespan of many larger EV batteries currently on the market.
Independent OEM testing has verified that Nyobolt’s 2.6Ah cells can withstand over 4,400 cycles with a rapid 12C charge rate and a normal 1C discharge at 23°C, with the internal cell resistance increasing by only 50% after these cycles—well below the industry’s typical end-of-life threshold.
Dr. Sai Shivareddy, co-founder and CEO of Nyobolt, points out that while some OEMs promote quick charging times, these often cover only a limited State of Charge (SOC) to minimize battery wear. Nyobolt’s technology, however, maintains peak charging levels for longer periods, significantly extending the battery's useful life up to 600,000 miles.
The compact size of the Nyobolt EV’s 35kWh battery not only charges faster but also offers benefits to automakers and drivers by enabling more energy-efficient, cost-effective, and resource-efficient electric vehicles.
Nyobolt’s prototype is a sports car weighing just 1,250kg, showcasing the potential for lighter, better-performing sports cars free from the constraints of conventional battery technology. Shane Davies, Nyobolt’s director of vehicle battery systems, emphasizes that the technology reinvigorates the excitement in the automotive segment by reducing the burden of heavy batteries.
Nyobolt is not only demonstrating the practical benefits of its fast-charging, long-life battery technology but is also planning for low-volume production of these battery packs within a year, with potential to scale up to two million cells annually. These batteries will comply with upcoming EU Battery Regulation standards.
The innovative design of the Nyobolt EV allows for potential retrofitting to existing EV platforms, significantly improving charge times and battery life. The battery modules are efficiently cooled using a cold plate system with a water/glycol mixture, ensuring optimal performance even under fast charging or intense driving conditions.
Building on a decade of research by University of Cambridge scientists, Nyobolt’s battery technology stands out for its ultra-fast charging capabilities that do not compromise battery lifespan, thanks to its innovative low-impedance cells. The company is already in discussions with eight more vehicle OEMs to adopt its technology in various applications, including robotics and heavy-duty commercial vehicles.
Dr. Shivareddy concludes, “Our extensive research in the UK and US has culminated in a scalable, novel battery technology that is ready for immediate deployment. By introducing products like the Nyobolt EV, we are demonstrating our commitment to pioneering change and electrifying new industries.”
