Qualification and verification of high-power battery systems for traction application

  • This paper reveals that the standard test procedures for the qualification and verification of traction battery systems are not sufficient in certain cases. In fact, realistic and application-oriented tests on the interaction among the complex battery subsystems are inevitable. To achieve these objectives, a high-performance test bench with the unique selling features of a high voltage/- and current range, extremely low ripple currents, and high dynamics is presented. For the operation of the applied multiphase current-sharing inverter for charging/discharging the device under test (DUT), special control algorithms, especially a current balancing control method, is introduced.
