Battery degradation isn’t just an engineering task — it’s a hidden programme cost that quietly scales into the millions. For OEMs running multiple cell programmes, durability testing often becomes a late-stage bottleneck that erodes margin, delays decisions, and limits flexibility.

Modern EV buyers expect ~500 km of range and 20–30 minute fast charging as standard. Delivering both in a single battery platform means pushing energy density to its limits without sacrificing safety, thermal performance or lifetime.

As we entered a new phase of commercial momentum with our Series B in May 2025, we took the opportunity to rethink how we distribute responsibilities between us to keep Breathe moving forward.

At Breathe, we’ve partnered with Bang & Olufsen to integrate our adaptive charging software, Breathe Charge, into Beo Grace. In internal testing, the earbuds delivered more than 2,000 charging cycles — around four times the typical lifespan of wireless earbuds. 

Batteries power the products that move us, connect us, and shape our future.
But the way we design them has not kept pace with the urgency of our ambitions.

We’re delighted to announce our partnership with Bang & Olufsen — a company that for more than 100 years has defined timeless craftsmanship in audio — to rethink what battery-powered products can achieve.

We are building a new kind of software toolchain. One that spans from the chemistry of the cell to the firmware in the vehicle on the road.

Breathe is expanding its software portfolio, providing comprehensive battery simulation and adaptive charging products.

Battery performance is changing. Not because of a new chemistry or a breakthrough material, but because software is finally giving electric vehicles and consumer devices the ability to understand what is happening inside their cells.

The conversation delves into the core principles of Breathe's innovative approach, which uses physics-based software to optimise battery performance and safety. Jingyi explains that while most people focus on external measurements like voltage and temperature, their technology goes a layer deeper, analysing the internal state of the battery to prevent the side reactions that lead to degradation.

We're excited to share insights from a recent episode of Imperial College London's Energy Futures podcast, featuring our very own Dr. Jingyi Chen, alongside Professor Martin Freer, CEO of the Faraday Institution. Hosted by Dr. Nadine Moustafa, this engaging discussion delved into the crucial role of energy storage in shaping a sustainable energy future and achieving net-zero goals.

Breathe Battery Technologies has been selected for The Europas 100 list, joining some of Europe’s most innovative and high-potential startups.

Welcome to a new era of electric mobility, where the secret to a better battery isn't just in its chemistry, but in its code. The true potential of electric vehicle (EV) technology lies in intelligent software that can adapt, optimise, and protect the very heart of the car: its battery.

At Breathe, we believe that the future of transportation and consumer electronics depends on pushing past the limitations of today's batteries. Our co-founders, Dr Ian Campbell and Dr Yan Zhao, recently took a behind-the-scenes look at our London headquarters with SpeedInvest to show how we’re building the batteries of the future.

With the dominance of lithium-ion batteries in the market today, the question arises: will we ever run out of lithium?  

Batteries are at the heart of the clean energy transition, powering everything from our smartphones to electric cars. But for all their importance, they have long been a source of frustration. Why do they degrade so quickly? Why can't they charge faster without harming their lifespan?

Volvo Cars’ new ES90 showcases a breakthrough in charging performance enabled by Breathe’s adaptive charging software. Integrated into Volvo’s in-house battery management platform, this collaboration demonstrates how model-based control can deliver faster charging.

Breathe's Co-founder and Chief Scientist, Professor Greg Offer, delves into the topic of battery swelling, answering key questions.

Leading global experts in battery control, Professor Gregory Plett and Professor Matthieu Dubarry, join Breathe Co-Founders, Professor Greg Offer and Dr Yan Zhao, to discuss the latest developments in the world of lithium-ion batteries, and what this means for OEMs and end-users.
