Stabl Energy is developing a technology that makes battery storage more efficient, safer, and more cost-effective. To do this, the Munich-based company divides high-voltage battery packs into many smaller modules. Using the specially developed technology, these modules are then dynamically interconnected. This concept is intended to protect against failures, improve safety, and save energy. Stabl's technology allows the use of both new and discarded batteries, such as those from electric cars. This gives old batteries a second use as stationary storage. (Photo: Stabl Energy)
