Abstract: A test system (110) for determining battery performance during development of a battery configuration in a test environment is proposed. The test system (110) comprises at least one communication interface (114) and at least one processing device (122). The test system (110) is configured for receiving operating data indicative of at least one test protocol via the communication interface (114). The test system (110) is configured for receiving battery performance input data via the communication interface (114). The processing device (122) is configured for determining at least one predicted time series of at least one state variable indicative of battery performance based on the battery performance input data and on the operating data using at least one data driven model. The test system (110) is configured for providing at least parts of the predicted time series of the state variable.
