Breathe Battery Technologies Raises $21M in Series B Funding

Breathe Battery Technologies, a London-based company specializing in AI-powered tools for predicting battery performance in electric vehicles and other devices, has secured $21 million in Series B funding.
The funding round was led by Kinnevik, with additional investment from Lowercarbon Capital and Volvo Cars Tech Fund.
The company plans to use the capital to accelerate its growth, expand its market reach, and further develop its technology.
Under the leadership of Ian Campbell, who serves as the co-founder and CEO, Breathe Battery Technologies focuses on enhancing battery performance through its physics-based battery management software. This software aids electric vehicle and consumer electronics manufacturers in delivering products with improved charging speed, longer cycle life, and enhanced safety. The company’s flagship product, Breathe Model, utilizes a Thermally Coupled Single Particle Model with electrolyte (TSPMe) to simulate the electrochemical and thermal dynamics of lithium-ion batteries accurately. This model is integrated into development workflows as a Simscape block.
Breathe Map is an interactive tool that allows users to analyze and optimize various charging performance attributes of their batteries, such as charge time, cycle life, charge time evolution, and thermal load, based on real data.
Additionally, Breathe Charge is a dynamic charging software platform that continuously monitors and adjusts a battery’s internal states in real-time, ensuring the optimal charging strategy is always in place.
With this recent funding injection, Breathe Battery Technologies is poised for significant growth and innovation in the battery technology sector.
