  • STABL Energy makes battery storage more efficient, safer and cheaper and enables easy recycling of second-life batteries 
  • Smart Energy Innovation Fund from Energie 360° leads the way. UVC Partners on board as a new investor. Existing investors such as Initiative for Industrial Innovators and various business angels have invested 
  • Fresh capital for product development, certification and expansion of the team.

Munich, 18.10.2021 – STABL Energy has successfully completed a financing round of EUR 4.5 million and gained UVC Partners as a new investor. The capital increase was led by Energie 360°’s Smart Energy Innovation Fund. Existing investors also participated significantly in the round, including the Initiative for Industrial Innovators and various business angels. The round was also made possible by Seitz-Partner, a leading law firm that advises start-ups and investors in financing rounds and growth phases. 
“We are delighted to have found partners in UVC Partners and the new investors who will help shape the success story,” says Ruth Happersberger, founder of the Smart Energy Innovation Fund and member of the management team at Energie 360°. 
“This investment round enables us to focus on growth and product development. The new capital will be used to expand the team, develop existing partnerships and prepare for entry into the European market,” says Dr. Arthur Singer, Co-Founder and Co-CEO of STABL Energy. 

Battery storage systems are key to a successful energy transition. They can store surplus electricity from solar and wind energy and make it available when the sun is no longer shining or the wind is not blowing. STABL Energy is developing a technology that makes these battery storage systems more efficient, safer and economical. 

Modular battery system for storing renewable energy

The core principle of the technology is to split high-voltage battery packs into many smaller modules that are dynamically interconnected using STABL technology. This concept guarantees a very high level of reliability and also improves safety – both in operation and during installation. This multi-level approach also means that less energy is lost during conversion, which reduces the operating costs of the storage systems.

Technology enables easy use of second-life batteries

In addition to the use of new batteries, STABL Energy’s innovative technology also makes it possible to reuse discarded batteries from electric cars. With the help of modular inverters, battery modules can be easily transferred from electric vehicles to stationary storage units. STABL technology can easily handle the sometimes very different residual capacities of battery modules from electric cars. This means that the storage units can be used for longer, which reduces their carbon footprint and makes the energy transition more sustainable and inexpensive.

What the investors say

“We were particularly impressed by the team’s ability to transform an innovative technology from university research into a functioning product with initial customers in a short space of time,” explains Johannes von Borries, Managing Director of UVC Partners. “STABL Energy is an important building block for the widespread use of alternative energy and benefits from the trend towards battery-powered cars and energy storage systems.” 
Metin Zerman, Investment Manager of the Smart Energy Innovation Fund of Energie 360°: “STABL Energy’s technology makes battery storage systems financially attractive for many applications. In particular, the flexibility and combination of different battery modules in a battery storage system – as well as the simple reuse of second-life batteries – make this concept extremely exciting.”

About STABL Energy

STABL Energy develops innovative, modular inverters for battery storage systems. Founded in Munich in 2019 as m-Bee by Dr. Arthur Singer, Dr. Nam Truong, Martin Sprehe and Christoph Dietrich, STABL’s technology makes commercial, industrial and grid storage systems more efficient, reliable, safe and affordable. 
The new approach also enables the seamless and simple integration of discarded batteries from electric vehicles. This increases the service life of these batteries, reduces their resource consumption and has a positive impact on the environment.
