Evaluation and Test of a Battery Management Unit for Hybrid Electric Vehicles
Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
In this thesis, the functions of a Battery Management Unit developed in house by Volvo Technology will be tested and evaluated in different aspects. The battery management system tested is a Kalman filter which uses measured cell voltage and current measurements to estimate the state of charge online. The system was tested against a Simulink model of a battery to verify its function in different conditions, and later on, the estimator was tested online with a battery pack consisting of 14 Li-ion cells. The cell balancing and state of power estimation was tested. Finally, a general test procedure to evaluate state of charge accuracy was proposed and tested.
