What Breathe Battery Technologies does
Breathe Battery Technologies is a London-based software company that develops physics-based battery management software for automotive, consumer electronics, and industrial battery manufacturers. Founded in 2019 as a spin-out from Imperial College London, the company's core technology — the PHI X2 platform — uses adaptive algorithms and real-time electrochemical state estimation to replace the conservative static lookup tables traditionally embedded in battery management systems. Its three commercial products are Breathe Charge (adaptive charging software that reduces EV 10-80% charging times by up to 30% without hardware changes), Breathe Simulate (cell simulation and degradation modelling), and Breathe Discover (cell candidate discovery for OEM engineering teams). The software is validated across more than 75 cell types spanning LCO, NMC, LFP, silicon-graphite, and pure graphite chemistries, with a recent expansion into AI-powered battery performance prediction tools.
Breathe generates revenue primarily through B2B enterprise licensing of its embedded software to OEMs, supplemented by subscription-based platform access for its simulation and discovery tools, plus cell parameterisation services and co-design studies. Its go-to-market is direct enterprise sales targeting tier-1 automotive OEMs (Volvo Cars, Polestar, Rimac, Cosworth), consumer electronics manufacturers (OPPO/OnePlus across 28+ device models, Bang & Olufsen), and industrial battery producers (VARTA). The company has achieved ASPICE Level 2 assessment compliance for automotive integration and holds patented adaptive charging algorithms. Total funding to date stands at approximately $32.5M across seed (Speedinvest, December 2021), Series A (Lowercarbon Capital, November 2023), and Series B (Kinnevik, May 2025, with Volvo Cars Tech Fund participation). Headcount doubled to approximately 60 employees in 2024 alongside a doubling of the company's London battery laboratory capacity.

Breathe Battery Technologies product offering
Product offeringCore offering
Breathe develops physics-based battery software for cell discovery, simulation, degradation prediction, and embedded charging control. Its principal products are Breathe Discover, Breathe Simulate, and Breathe Charge, which manufacturers can use across battery design, validation, and production through existing battery management systems.
Product overview
Breathe Battery Technologies offers a physics-based battery software toolchain comprising three core products: Breathe Discover (battery cell discovery platform for identifying high-potential cell candidates), Breathe Simulate (cell simulation and degradation modeling solutions), and Breathe Charge (embedded adaptive charging software). The three products are architecturally unified on the PHI X2 physics-based battery model platform, enabling a "left-shift" in development where battery control software is co-developed with cell hardware. Breathe Charge embeds into existing battery management systems to deliver real-time adaptive charging optimization, while Breathe Discover and Breathe Simulate support upstream cell design and validation. The toolchain enables customers to evaluate 10x more cell candidates before prototyping and reduces development costs. The company also offers cell parameterisation services and co-design studies as supplementary offerings.
