Large-scale storage system with innovative cooling management and economical design


Energy Lab 2.0 is a large-scale research infrastructure for the research on the interaction of components for future energy systems and the testing of new approaches to stabilizing energy grids. A prototype of a large-scale Li-ion battery system with 1.3 MWh of storage capacity is being developed by Battery Technical Center in the Energy Lab 2.0. The focus is on an economical design using a pre-cast concrete structure with an innovative liquid cooling concept and thermal component activation. To attain the highest safety standards for low system costs, mass-produced battery modules are used. The pre-cast concrete structure allows for minimal construction and installation times. Due to its high level of flexibility, the storage system can be used to provide primary balancing power, as day/night compensation or in industrial applications. To do this, an intelligent overall control system is being developed to ensure the economic and grid-supportive operation of the battery. The economic viability of the system is increased by self-learning forecast algorithms for energy generation and demand, which both maximize battery service life and reduce load peaks in the grid.
