Gaussion Raises $28M to Expand Magnetic Charging

The big picture: Gaussion, a London-based battery startup, has raised $28 million to expand its magnetic charging technology. The company argues that battery limitations are the primary bottleneck for advancements in AI data centers, electric vehicles, and autonomous systems. This funding brings its total raised to over $44 million. Gaussion aims to address this by enhancing existing lithium-ion batteries without altering their chemistry or design.

Why it matters:

• Critical bottleneck: While focus often remains on chip shortages and computing power, Gaussion highlights that battery technology is the true constraint holding back AI, EVs, and other advanced systems.
• Unique approach: Unlike most battery companies that focus on cell chemistry, Gaussion uses an external magnetic field to enable faster charging and extend the lifespan of existing lithium-ion batteries.
• Market opportunity: The global battery management system market, valued at $9.97 billion in 2026, is projected to reach $17.86 billion by 2030, driven by AI infrastructure, EV adoption, and grid storage.

How it works:

• Core technology: Gaussion develops MagLiB, a magnetic printed circuit board, and Aeon, a specialized control chip and software platform, which together form a smart control layer within battery packs.
• Broad applications: This system facilitates rapid EV charging, extends drone flight times, and improves power management in data centers, all without requiring changes to the battery cell itself.
• Strong IP and traction: The company supports its technology with 66 patent applications across 17 families and is engaged in 14 active commercial programs with manufacturers in automotive, aerospace, grid storage, and consumer electronics.

The catch: The battery intelligence and management sector is highly competitive and undergoing consolidation, as evidenced by the acquisition of UK competitor Brill Power. While some rivals like Nuvation Energy focus on specific applications, Gaussion’s retrofit approach aims for broader commercial reach across the entire lithium-ion stack, from consumer electronics to data centers. This wide scope presents both a significant opportunity and a complex challenge for integration and market penetration.
