Nyobolt, a UK-based developer of ultra-fast-charging batteries, has announced the launch of its advanced battery technology as a mobile DC supercharger for electric vehicles (EVs).

Following its demonstration of a six-minute ultra-fast-charging EV, Nyobolt has developed a compact battery-integrated supercharger, named ‘Bolt-ee’, offering up to 300kW DC charge power. This innovation addresses a major hurdle in the EV transition: the charging infrastructure. Bolt-ee can be recharged in six minutes and offers a battery life of over 10,000 charging cycles.

In 2022, 14% of all new cars sold globally were electric, an increase from 9% in 2021. The growing adoption of EVs necessitates a significant expansion in charging point availability to match the convenience of petrol refuelling. However, challenges such as planning permission, extensive trenching, and grid connection have hindered progress. Nyobolt's supercharger presents a solution by eliminating the need for trenching and civil works, effectively turning every parking bay into a potential charging bay.

The European Union is estimated to require at least 3.4 million operational public charging points by 2030 to fully transition from ICEs to EVs, highlighting the current gap in charging infrastructure. In the US, the number of charge points is expected to rise from about 4 million to 35 million by 2030. China aims to establish an advanced charging infrastructure by the end of 2025 to support over 20 million electric vehicles. Fast DC charging availability without stressing the grid could further enhance this transition, offering convenience over slower chargers.

Sai Shivareddy, CEO and Co-Founder at Nyobolt, said: “Nyobolt has already cracked the challenge of substantially reducing battery charging times, having achieved a six-minute charge car, and developed smaller battery packs that can deliver faster and higher power charging, but this is not where the challenge ends. As our world accelerates, immediate access to fast-battery charging is a necessity. Our technology meets this urgent call by driving the present into a charged future.”

Beyond supporting charging infrastructure expansion, mobile battery-integrated superchargers have practical applications. Currently, flat batteries account for around 2% of EV driver callouts. A lightweight, compact charger like Bolt-ee enables recovery vehicles to add it to their toolkit without significant space or weight concerns.

Professor Clare Grey, Chief Scientist and Co-Founder at Nyobolt, commented: “Nyobolt’s vision has always been to support a seamless transition to clean energy and a net-zero world. There are many innovative manufacturers creating the EVs of the future. Nyobolt’s ready-to-deploy technology, which will go into production in early 2024, will help accelerate the adoption of EVs, by improving the user experience with faster, and provide more accessible charging for all – particularly for those who may not be able to charge at home.”
