The Munich-based startup Delta Charge, founded in 2024, develops charging and battery storage solutions for electric trucks. In an oversubscribed funding round led by Vireo Ventures and Rethink Ventures, it has raised €3.7 million ($4.3 million) to expand its solutions. The capital will accelerate the development of a pan-European network of truck charging parks and battery-supported industrial hubs. Other investors in the round include executives from Audi and Allianz, German family offices, and founders from Munich’s climate-tech ecosystem.
Access to efficient energy supply at scale
Delta Charge develops solutions at the intersection of electric mobility and energy infrastructure. The company combines battery energy storage systems (BESS) with charging hardware, energy management, and fixed-price charging services. With this, the Munich-based startup aims to enable European logistics and industrial companies to have economical access to energy supply at scale. The young company is supported by Delta Capacity, a leading Scandinavian developer and investor in battery storage. By 2030, Delta Charge plans to invest over €300 million in infrastructure and provide 1.8 terawatt-hours of clean energy annually.
Filip Hes, CEO of Delta Charge, says:
“This funding package marks a decisive moment for Delta Charge: we’re seizing a unique opportunity to meet historic load growth and shape a new infrastructure class at the heart of Europe’s energy transition. With Rethink’s goal of redefining the transport sector, Vireo’s strong commitment to electrifying Europe, and Delta Capacity’s experience with large-scale battery projects, we are optimally positioned to accelerate expansion along our project pipeline.”
Goal: reduce CO2 emissions in heavy-duty transport
The timing of the funding is strategically chosen: the electrification of heavy-duty transport is currently driving strong electricity load growth. A trend that could soon exceed the energy consumption of European data centers. Transport could account for almost 50 percent of Europe’s CO₂ emissions by 2030. Accordingly, logistics and freight transport offer one of the greatest potentials to reduce emissions while lowering costs per kilometer.
Jens Philipp Klein, general partner at Rethink Ventures, explains:
“The most economical operation of electric truck fleets will depend on intelligent depot charging solutions that combine battery storage, charging infrastructure, and seamless software integration. The Delta Charge team brings deep expertise in energy infrastructure, advanced battery software, and the financing and implementation of large infrastructure projects.”
Given increasing grid bottlenecks and longer approval processes, market observers expect depot-based charging and battery storage solutions to attract over seven billion euros in investment by 2030. With its position at the intersection of logistics and energy flexibility, Delta Charge aims to create a central element of the infrastructure that enables Europe’s carbon-free freight transport.
