DOYAM-LiONEis Battery Charge and Ageing Status Determination System

under development

The start-up project DOYAM-LiONEis at the Institute for Electrical Machines, Traction and Drives (IMAB) at Technische Universität Braunschweig is developing hardware and software solutions to accurately determine the charge and ageing status of lithium-ion batteries. This technology enables optimized operation, extends the service life of battery energy storage systems, and reduces operating and investment costs as well as maintenance requirements. The solution uses electrochemical impedance spectroscopy combined with machine learning algorithms and modular power electronic converters for application to large cell stacks in grid-connected batteries.
