Battery management software provider Breathe Battery Technologies announced that it has raised $21 million in a Series B financing round, as the company launches a suite of battery simulation software, embedded software and battery services.
Spun out of Imperial College in 2019, London-based Breathe provides tools aimed at enabling the design, validation and optimization of better batteries, including physics-based simulation and embedded software products encompassing the full battery development lifecycle.
Alongside the capital raise, Breathe announced the launch of three new products, including Breathe Model, an advanced cell simulator software solution enabling high-level simulations based on physics-based electrochemical and thermal dynamics; Breathe Map, a performance mapping service aimed at revealing the full potential of batteries by uncovering balance between the cells’ charging performance and the battery’s internal states, and; the soon-to-be-released Breathe Design software, aimed at enabling engineers to create more performant, cost-effective battery systems with system-level, contextual knowledge.
Breathe said that the new capital will be used to accelerate the company’s growth, expand its physics-based battery software capabilities, and more than double the size of its London battery testing facility.
Dr. Ian Campbell, CEO of Breathe said:
“Breathe has evolved to become a leading company in battery technology, with the funding and infrastructure to match our ambition and deliver a major impact on battery innovation. The industry can no longer afford incremental progress, it needs transformative technology that makes batteries fundamentally better. Our software toolchain improves EV charging for end-users and helps manufacturers cut costs, reduce risk, and accelerate battery system development.”
Investors participating in the funding round included new investor Kinnevik AB, and returning investors Lowercarbon Capital and Volvo Cars Tech Fund. Breathe recently announced that Volvo Cars will feature its software solution, Breathe Charge, which dynamically controls charging current by managing internal electrochemical states, on its upcoming ES90 sedan.
Ann-Sofie Ekberg CEO, Volvo Cars Tech Fund said”
“Charging isn’t just about being fast or slow anymore, it’s about delivering a consistent experience that makes EV ownership effortless for customers. Breathe’s technology enables us to optimise charging across a wide spectrum of real-world conditions, improving speed and consistency while protecting battery health. Breathe’s software and expertise give us critical insights earlier in the development, allowing us to make more informed decisions, reduce risk, and ultimately create more efficient battery systems.”
