Testing & Evaluation

Testing and evaluation for reliable energy storage systems

Testing and evaluation are essential for the development of safe and efficient energy storage systems. The Fraunhofer Battery Alliance conducts electrical, thermal and mechanical tests according to common standards and customer-specific requirements. This includes material characterization, performance tests, analysis of service life under various environmental conditions, determination of operational stability and system reliability as well as safety tests. Safety tests also include the behavior of batteries under accident conditions. The test facilities enable time-resolved analyses of released substances and heat, crash research, material characterization as well as stress and load tests. Depending on requirements, battery tests are carried out at cell, module or system level.
