Battery storage systems are key for a successful energy transition. They can store excess electricity from solar and wind power 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, safe, and affordable.

Modular battery system to store renewable energy

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

STABL technology enables easy use of second-life batteries

In addition to using 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. The STABL technology can easily handle the wide variation of 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 affordable.

Here's what the investors are saying:

"We were particularly impressed with the team, because they were able to take an innovative technology from university research and turn it into a working product with initial customers in a short period of time," said 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." Metin Zerman, Investment Manager of Smart Energy Innovations Fund of Energie 360°:

"STABL Energy's technology also makes battery storage financially attractive for many applications. The flexibility and combination of different battery modules in one battery storage system – as well as the easy reuse of second-life batteries – make this concept extremely exciting."

About STABL Energy

STABL Energy is a provider of novel, modular power inverters for battery systems. Founded in Munich, Germany in 2019 (then called m-Bee) by Dr. Arthur Singer, Dr. Nam Truong, Martin Sprehe and Christoph Dietrich, the STABL technology makes commercial and utility scale energy storage systems more efficient, reliable, safe, and affordable. The new approach also allows seamless and easy integration of used car batteries, which extends the lifetime of batteries and reduces their resource consumption.
