Munich-based firm Delta Charge, which builds battery systems for electric depots and industrial hubs, has raised $4.3 million in funding led by Vireo Ventures and Rethink Ventures.
- Founded in 2024 by Filip Hes, Connor Hanafee, and Johannes Kirnberger, Delta Charge develops and operates battery-based energy infrastructure for electrified truck depots and industrial sites.
- The company builds systems that combine commercial-scale battery storage, charging hardware, and energy-management software, allowing logistics operators and industrial facilities to manage high power loads, integrate onsite renewables, and charge electric fleets even where grid capacity is limited.
- Delta Charge handles the full process, from system design and permitting to construction and long-term operation, providing integrated battery and charging installations that tie into a customer’s existing solar, software, and operational tools.

- The round was led by Vireo Ventures and Rethink Ventures, with participation from executives at Audi and Allianz, German family offices, and founders from Munich’s climate-tech ecosystem.
"Operating electric truck fleets at the lowest possible total cost of ownership will rely on smart depot charging solutions that combine battery storage, charging infrastructure, and seamless software integration. The team at Delta Charge brings deep expertise across energy infrastructure execution, advanced battery software, and a track record of raising hundreds of millions towards rapidly scaling and executing infrastructure pipelines," explains Jens Philipp Klein, General Partner at Rethink Ventures.
- Delta Charge will use the fresh funding to accelerate the rollout of its pan-European network of electric truck-charging depots and battery-enabled industrial hubs, helping scale its combined BESS, charging hardware, and energy-management platform across Europe.
"This financing marks a defining moment for Delta Charge as we scale our platform and continue to execute our vision. We are seizing a once-in-a-decade opportunity to serve historic load growth and shape a new infrastructure asset class at the heart of Europe's energy transition. With Rethink's ambition to redefine transportation and Vireo's strong commitment to European electrification, as well as Delta Capacity's experience executing large scale battery projects, we are uniquely positioned to accelerate deployment across our pipeline," claims Filip Hes, CEO of Delta Charge.
