To solve the problem of battery cell disparity in lithium-ion battery systems, battery balancing techniques are necessary. This paper proposes an improved battery balancing strategy using a reconfigurable converter system. The strategy is based on the state of charge (SOC) of batteries and utilizes the converter system to transfer energy from batteries with high SOC to those with lower SOC. The simulation results demonstrate that the proposed strategy achieves more efficient and accurate battery module balancing compared to previous modes.
In order to address the issue of battery cell disparity in lithium-ion battery systems, battery balancing techniques are required. This paper proposes an improved battery balancing strategy within a reconfigurable converter system. The strategy is based on the state of charge (SOC) of batteries, and utilizes the reconfigurable converter system to transfer energy from battery modules with high SOC to those with lower SOC. Additionally, it allows for battery module balancing while supplying power to loads. A MATLAB/Simulink simulation model with five batteries was built to validate the effectiveness of the proposed balancing strategy under unloaded and loaded conditions. The simulation results demonstrate that the proposed strategy achieves more efficient and accurate battery module balancing compared to the previous balancing modes.
