Özet
© 2021, The Korean Institute of Power Electronics.In this study, a novel battery management system (BMS) circuit topology based on passive and active balancing methods was created and implemented for battery-based systems. The circuit topology was designed so that both of the control methods can be applied when suitable software is used. A resistance-based passive control method was used. MOSFET switching elements were used as a load instead of a resistance. A bypass technique-based active balancing method was applied to the designed BMS. The applicability of these methods was separately tested as passive and active-based experimental systems. During the charging process, a voltage increase of the cells was observed at approximately 0.140 V after 16 min in the passive balancing mode. On the other hand, the voltage increase was measured at 0.155 V after 14 min in the active balancing mode. The average temperature of the cells in charge states was measured as approximately 25 °C. The obtained experimental results verified that the proposed BMS topology can work successfully in both active and passive balancing operations. As a result of this study, active and passive balancing circuit structures were combined, and a new circuit topology has been introduced.
