As Europe’s energy grid faces strain, Munich’s Delta Charge raises €3.7 million to capitalise on electrification and BESS needs

Delta Charge, a Swedish-German company that is pioneering charging and battery storage solutions for electric trucks, has raised €3.7 million ($4.3 million) equity in an oversubscribed funding round.

The round was led by Vireo Ventures and Rethink Ventures. The round includes executives from Audi and Allianz, German family offices and founders of Munich’s ClimateTech ecosystem. The funds will accelerate the growth of Delta Charge’s pan-European network of truck-charging depots and battery-enabled industrial hubs.

“This financing marks a defining moment for Delta Charge as we scale our platform and continue to execute our vision,” says Filip Hes, CEO of Delta Charge.

Delta Charge’s funding round is part of a larger trend in 2025, where significant investments are being directed towards battery storage and electrification infrastructure in Europe.

Other companies in this space have also raised notable amounts to accelerate similar innovations.

For instance, iwell secured €27 million to expand its smart battery storage systems and energy management solutions across Europe. Terra One raised up to €150 million in mezzanine financing for its large-scale battery storage portfolio. Sympower secured an additional €42 million in a Series B1 extension to enhance its BESS optimisation platform across Europe. Co-Power raised €6.4 million to deploy decentralised battery storage and solar systems for industrial clients. Lastly, green flexibility is leading large-scale battery storage projects with equity backing of up to €400 million.

Collectively, these funding rounds result in €625.4 million of active funding in the sector – highlight the growing financial commitment to supporting Europe’s energy transition and decarbonisation of heavy transport.

“We are seising 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,” adds Hes.

Founded in 2024 in Munich by Filip Hes, Johannes Kirnberger and Connor Hanafee, Delta Charge combines battery energy storage systems (BESS) and charging hardware, energy management, and fixed-price charging services to enable European logistics and industry to unlock the economic advantages of large-scale energy operations.

The company develops and finances a pan-European network of truck-charging depots and battery-enabled industrial hubs. Its platform combines intelligent software, grid-connected batteries, and fixed-price charging services to help fleet operators electrify their operations while supporting a more flexible and resilient power grid.

Backed by Delta Capacity, one of Scandinavia’s leading battery storage developers and investors, Delta Charge aims to deploy more than €300 million in infrastructure and deliver 1.8 TWh annually of clean energy by 2030.

“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,” added Jens Philipp Klein, General Partner at Rethink Ventures.

“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,” adds Klein.

The announcement comes at a time when heavy-duty electrification is driving unprecedented load growth that could soon rival or even exceed the electricity consumption of Europe’s data centres.

According to data presented by the company – as transport could account for almost 50% of the continent’s CO2 emissions by 2030, logistics and freight operations present one of the largest untapped opportunities to substantially cut emissions while reducing per-kilometre costs.

With grid capacity tightening and permitting slowing, depot-based charging and battery storage are projected to attract more than €7 billion in investment by 2030.

Positioned at the intersection of logistics and energy flexibility, Delta Charge aims to anchor the infrastructure powering Europe’szero-carbon  freight future.
