Breathe Battery Technologies has secured £16m in Series B funding to accelerate adoption of its predictive battery software. The round was led by Kinnevik with participation from Lowercarbon Capital and Volvo Cars Tech Fund.
Breathe provides software tools that enable electronics and automotive manufacturers to improve battery performance, predict long-term outcomes, and reduce development time. The company’s suite of products — including Charge, Model, Map, and the soon-to-launch Design — helps optimise battery behaviour based on individual cell characteristics and use cases.
Initially focused on fast charging, Breathe’s software is now used by consumer electronics firms and EV manufacturers. Mobile brand Oppo was an early adopter, achieving a 27% reduction in charging time. Volvo is integrating Breathe’s technology into its upcoming ES90 electric sedan to enable rapid charging from 10% to 80% in 20 minutes.
The London-based company operates a dedicated lab to run advanced testing and modelling for its customers. Its Model and Map products allow customers to simulate future battery performance and then validate those assumptions with real-world data, helping teams make informed trade-offs between speed, longevity and cost.
Breathe’s mission is to bring semiconductor-style software tooling to the battery industry, enabling faster and smarter development cycles in a sector where performance and efficiency are key to product success.
