Reconfigurable batteries or multilevel inverters are becoming increasingly important in current power electronics research. In the automotive sector in particular, a reconfigurable battery system can offer numerous advantages in terms of cost, efficiency and longevity, and support the transition to sustainable transport. An important aspect of reconfigurable batteries is the ability to perform proactive balancing, which mitigates traditional balancing losses and charging speed degradation as well as extends battery life due to the pulsed current profile, even in DC charging and discharging scenarios. An automated test setup is created and explained to perform proactive balancing procedures with variable parameters. The use of battery emulators guarantees the repeatability and comparability of test runs and increases overall safety during testing. The different test runs are analyzed and compared with regard to balancing success and efficiency. The results demonstrate that a total SoC deviation of over 60 % between all cells can be compensated within a single (dis)charging cycle while maintaining an average system efficiency of 98 % and a stable output voltage. Further investigations are planned to include real battery cells and optimize the algorithm for higher accuracy.      «
