A Fast Equalization Control Strategy for Series-Connected Battery Clusters Based on Switch-Multiplexing Multiresonant Switched-Capacitor Converter
The increasing integration of renewable energy necessitates battery energy storage systems (BESS) to ensure grid stability. To achieve higher voltages, multiple battery packs are typically connected in series, making state-of-charge (SOC) balancing among different packs critical for safe and stable operation. This paper employed the Switch-Multiplexing coupled Multi-Resonant Switched-Capacitor Converter (SMX-MRSCC) topology for battery equalization due to its cost-effectiveness achieved through switching devices reuse. However, this multiplexing also introduces coupling in SOC control between packs. Conventional strategies rely on continuous regulation of phase-shift ratios for decoupled control, often compromising soft-switching operation and increasing power reflux. To address this issue, a novel phase-shift control strategy is proposed in this paper. The phase-shift ratios are discretized into three predefined states: forward/reverse states and an idle state, optimized to achieve low reflux power, and low RMS current and peak current under soft-switching constraints. Specifically, to realize efficient equalization by fixed operating states, the state selection for phase-shift ratios of every two adjacent half-bridge is dynamically determined based on the accumulated imbalance energy (AIE) of the upstream battery packs, which minimizes energy interaction through path optimization. Therefore, the proposed approach enhances equalization efficiency by component-level optimal design and system-level energy transfer path optimization. Experimental results demonstrate the effectiveness of the proposed method in achieving efficient SOC balancing for series-connected battery packs.
