Electric truck charging startup Delta Charge secures millions in financing

Delta Charge describes itself as a “German-Swedish developer of innovative charging and battery storage solutions for electric trucks.” The young company aims to combine battery energy storage systems (BESS) with charging infrastructure, energy management, and “transparent fixed-price offers.”

According to the company, “this enables Delta Charge to help logistics and industrial companies reap the economic benefits of large-scale energy platforms.” The focus on connecting battery storage to charging infrastructure is no coincidence: Delta Charge is supported by Delta Capacity, “one of Scandinavia’s leading developers and investors in large-scale battery storage.”

The approach is more relevant than ever: the rapid expansion of charging infrastructure is increasingly being slowed down by lengthy approval procedures and grid connections, as Federal Transport Minister Patrick Schnieder also noted on the same day at his ministry’s charging infrastructure conference. This is particularly true for electric trucks with large batteries and high charging capacities; high-performance grid connections are quickly becoming a necessity – whether for charging many vehicles in depots or for megawatt charging on the highway. Delta Charge aims to remedy this situation in depots with flexible charging and battery storage solutions.

The ambitions are big: according to the announcement, Delta Charge wants to make “investments of more than €300 million in energy and charging infrastructure” by 2030 and plans to provide 1.8 terawatt hours of clean energy annually.

In 2025, the dimensions are still somewhat smaller, but nevertheless remarkable. In an oversubscribed financing round, the startup secured $4.3 million, equivalent to €3.73 million. “The round was led by Vireo Ventures and Rethink Ventures; senior executives from Audi and Allianz, German family offices, and founders of the Munich climate tech ecosystem also participated,” Delta Charge announced.

“The financing is a crucial step in rapidly scaling our platform and consistently implementing our vision,” said Filip Hes, CEO of Delta Charge. “We are serving the rapidly growing electricity demand of European logistics and actively shaping the infrastructure of the energy transition. With Rethink’s deep understanding of the transformation of mobility, Vireo’s expertise in the electrification of energy systems, and Delta Capacity’s experience in building large battery storage projects, we are ideally positioned to accelerate the implementation of our pipeline.”

“The economic operation of electric truck fleets will depend in the future on intelligent depot charging solutions that combine battery storage, charging infrastructure, and seamlessly integrated software,” says Jens Philipp Klein, General Partner at Rethink Ventures. “The Delta Charge team combines extensive experience in implementing energy infrastructure projects and developing complex battery software with a strong track record in building and financing scalable infrastructure pipelines.”
