STABL Energy, established in 2019 in Munich, Germany, develops advanced battery storage solutions for commercial applications. The company originated from research projects at the Technical University of Munich and the University of the Bundeswehr Munich. Initially known as m-Bee GmbH, the company adopted its current name in July 2020. STABL Energy specializes in creating efficient power conversion technology that improves the integration of energy storage with renewable energy sources. With over 40 professionals, including experts from Tesla and BMW, the company brings extensive experience in battery technology and power electronics to create reliable storage systems.
Battery Technology
STABL Energy’s primary innovation lies in its modular multilevel inverter (MMI) technology, which transforms how battery storage systems connect to power grids. This patented technology enables the direct connection of low-voltage battery modules in series to generate a staircase voltage that closely matches sine wave requirements. This approach reduces energy losses by up to 70% and decreases operating costs by approximately 40%.
The company’s technology excels in integrating second-life batteries from electric vehicles into stationary storage applications. Their system can efficiently combine batteries in different conditions within a single storage unit, extending battery lifespans and reducing resource consumption. STABL Energy offers two main product lines:
- Outdoor cabinets with 128 or 205 kWh usable capacity
- 20 ft containers with capacities from 256 kWh to 1,233 kWh
Each system features continuous monitoring capabilities, providing real-time data on battery health, temperature, current, and voltage. This detailed analytics helps optimize performance and assists insurers in risk assessment. The technology achieves up to 97% overall efficiency for charging and discharging operations, setting new standards for commercial energy storage solutions.
Recent Projects
In late 2023, STABL Energy secured €15 million in financing to expand its commercial operations and advance its battery storage technology development. The company has focused on implementing its storage solutions across various commercial sites in the DACH region, demonstrating significant cost reductions and improved energy efficiency for businesses.
STABL Energy has also expanded its product portfolio with enhanced outdoor cabinet solutions, offering improved capacity and performance metrics. These developments reflect the company’s commitment to making sustainable energy storage more accessible to commercial customers.
Investors
STABL Energy maintains strong financial backing from several notable investors. The most recent €15 million funding round included participation from Nordic Alpha Partners and the European Innovation Council. Previous investors include:
- UVC Partners
- Smart Energy Innovation Fund (Energie 360°)
- Initiative for Industrial Innovators
- Various business angels
The European Innovation Council initially provided a €2 million grant for technology development before participating in additional funding rounds. This diverse investor base demonstrates confidence in STABL Energy’s technology and market potential.
