UK battery software developer Breathe Battery Technologies has raised $21 million in Series B funding and expanded its product portfolio from an embedded software program to a suite of battery simulation software, embedded software and battery services to support the full battery development process.

The round brought in Swedish investment company Kinnevik, alongside previous investors Lowercarbon Capital and Volvo Cars Tech Fund. Volvo Cars was the first automaker to use the latest version of the Breathe Charge software in its new generation of EVs. Back in 2021, Breathe raised $2 million in a funding round led by Speedinvest.

The new funding will enable Breathe to expand its physics-based battery software capabilities and more than double the size of its London battery testing facility.

Breathe’s London lab has now expanded from 7,500 square feet, adding a further 6,000 square feet to house more than 696 testing channels, including over 150 automotive channels and more than 2 million hours of battery testing data.

The company has launched three new products—Breathe Model, Breathe Map and Breathe Design.

Breathe Model is advanced cell simulation software that provides developers with high-level simulations based on physics-based electrochemical and thermal dynamics. The Breathe Map service delivers performance mapping to show battery capabilities. Breathe Design is cell design software that enables engineers to create high-performance, cost-effective battery systems with system-level, contextual knowledge, according to the company.

These new products complement the company’s Breathe Charge adaptive charging software, which Volvo Cars recently announced will be featured in its upcoming ES90 sedan.

“Our software toolchain improves EV charging for end-users and helps manufacturers cut costs, reduce risk, and accelerate battery system development.  This funding allows us to expand our technology capabilities, our team and our lab so we can push battery performance further,” said Dr. Ian Campbell, CEO of Breathe.
