Gaussion Raises $28M for Magnetic Battery Tech

Jan de Vries · 2026-06-29

Gaussion, a London-based DeepTech company pioneering energy intelligence technology for battery packs, today announced the close of a $28 million (€24.5 million) funding round. This brings the company's total funding to over $44 million (€38 million). The round was co-led by BGF and AlbionVC, with follow-on participation from mobility specialist fund Autotech Ventures, UCL Technology Fund, DN Capital, and Future Ventures. "The race everyone's watching is about computer chips, but the real prize is the battery. The battery decides whether the giant computers behind AI can keep running. Whether a drone can stay in the sky. Whether a satellite survives out in space. Every battery faces a physics ceiling, and we move that ceiling," says Tom Heenan, CEO and co-founder of Gaussion. ### A Surge in European Battery Investments Gaussion's round follows a series of 2026 EU-Startups-reported investments into European battery, energy storage, and adjacent energy-intelligence companies. At least $145.6 million (€139.7 million) has been disclosed across comparable rounds so far this year. These include: - Munich-based TWAICE's $25 million (€24 million) EIB financing for predictive battery analytics. - Entrix's $44.8 million (€43 million) raise for battery optimization and flexible energy trading. - encosa's $26 million (€25 million) Seed round for commercial and industrial battery storage. - Helsinki-based Capalo AI's $11.5 million (€11 million) Series A for AI-powered battery storage optimization. - Copenhagen-based Hybrid Greentech's over $15.6 million (€15 million) investment for virtual power plant rollout. - Oslo-based Photoncycle's $15.6 million (€15 million) Series A for seasonal energy storage. In the UK, London-based Polaron also raised $7 million (€6.7 million) for AI-led materials science across batteries, automotive, and energy, making it the closest same-country comparator. EU-Startups previously covered Gaussion's $11.4 million (€10.9 million) Series A in 2024. ### Investor Confidence and Technology Validation "Gaussion has made huge strides in a short space of time to validate its technology, scale operations, and increase commercial traction. The business possesses a truly differentiated offering, underpinned by an incredibly versatile product, with the potential to address a fundamental performance and cost issue in battery systems. We are delighted to invest in Gaussion for a third time, made more exciting as the deal that took BGF over the threshold of £5 billion invested in UK and Irish businesses," adds Dennis Atkinson, co-Head of Early Stage at BGF. ### The Technology Behind Gaussion's Magnetic Intelligence Founded in 2022 as a spinout from University College London and the Faraday Institution, the UK's flagship battery research program, Gaussion develops MagLiB, a magnetic PCB retrofit system, and Aeon, a proprietary control chip and over-the-air intelligence platform. Together, they create an intelligent control layer inside battery packs. Gaussion has 66 applications across 17 patent families, with commercial programs spanning automotive, aerospace, grid storage, consumer electronics, and others. Their technology uses an external magnetic field to enable rapid charging. It reportedly improves the performance and lifespan of battery systems using proprietary, AI-enabled control software, with no change to battery chemistry or design. The technology works with any lithium-ion battery across a wide range of applications, from charging EVs and drones to powering data centers. ### Scaling Up: New London Facility In October 2025, the company moved into a new 40,000 square foot facility in central London. This opens what the company claims to be one of the largest battery R&D locations in Europe. "Batteries underpin the modern world, from EVs and grids to consumer devices and data centers, yet every battery faces the same fundamental ceiling on performance and lifespan. Gaussion has created a new layer in the battery stack: a magnetic intelligence layer that dramatically lifts performance across any chemistry or format. It is a rare opportunity to back a company that touches the entire battery lifecycle, from gigafactory formation to deployment," the company stated. Gaussion's approach is unique because it doesn't require changing the battery's chemistry or design. Instead, it adds an intelligent layer that works with existing lithium-ion batteries. This makes it a versatile solution for many industries. The recent funding will help Gaussion scale its operations and expand its commercial reach. With the new facility, the company is well-positioned to advance its technology and meet growing demand for better battery performance. As the world relies more on batteries for everything from electric vehicles to data centers, Gaussion's technology could play a key role in overcoming current limitations. The company's focus on magnetic intelligence offers a promising path to improving battery life and performance without costly redesigns. For investors and industry watchers, Gaussion represents a significant step forward in energy intelligence. Its ability to work with any lithium-ion battery makes it a valuable player in the evolving energy landscape.
