The Bavarian State Brewery Weihenstephan is the world’s oldest brewery. It has existed since 1040. But no matter how old it is, its operations are state-of-the-art. And in the future, they will become even more so, as the brewery has inaugurated a fully electrified charging and energy depot at its logistics center together with Munich-based startup Delta Charge, a company for charging infrastructure and battery storage solutions for electric trucks – customized for the state brewery’s growing electric truck fleet.
The depot is not just about charging individual e-trucks; rather, the industrial logistics site is designed as an integrated energy system. A major and important step for the Munich and Bavarian ecosystem. Delta Charge demonstrates how charging infrastructure, battery storage, and AI-powered energy management can work together economically for commercial fleets.
And for the Munich ecosystem, this is indeed a major and important step, as the partnership brings together two companies from Bavaria’s capital: Weihenstephan State Brewery is based in Freising. Delta Charge is a German-Swedish startup that develops charging and storage solutions for electric utility and heavy-duty vehicles. Just in November 2025, the climate tech company raised a financing round of €3.7 million to expand the e-truck charging network.
150-kW fast chargers and 380-kWp PV system for e-truck logistics
The logistics center was designed as a fully integrated energy solution. Two ceiling-mounted 150-kW fast charging stations are powered by a modular battery storage system. Starting with a capacity of 125 kW/257 kWh and expandable to 375 kW/771 kWh – in line with the growth of the electric fleet – the battery storage seamlessly integrates the site’s existing 380-kWp PV system.
The centerpiece of the project is Delta Charge’s custom-developed AI-powered energy management system, which continuously optimizes the interplay of solar energy, battery storage, and charging processes to minimize grid dependency and reduce electricity costs. The result is a system that not only operationally enables electric trucks but makes them cheaper than their diesel counterparts over their entire lifespan.
AI energy management to undercut diesel costs
According to Weihenstephan and Delta Charge, the system should make electric trucks cheaper than diesel counterparts over their entire lifespan. The key to this is not just the vehicle switch, but the combination of self-generated solar power, battery storage, load management, and planned charging processes.
“The electrification of our fleet is a natural expression of this responsibility and a concrete step on our path to complete decarbonization”,
says Josef Schrädler, director of the Bavarian State Brewery Weihenstephan.
Delta Charge plans to scale charging and storage hubs across Europe
Delta Charge plans investments of more than €300 million in energy and charging infrastructure by 2030 and aims to provide 1.8 terawatt-hours of clean energy annually. The Weihenstephan project serves as a reference for logistics and industrial sites that want to operate e-truck fleets without costly grid expansion.
Johannes Kirnberger, CEO of Delta Charge:
“Our concept works both technically and economically, and we are ready to establish it across Europe in logistics and industry”
