Battery management system-balancing modularization based on a single switched capacitor and bi-directional DC/DC converter with the auxiliary battery Vrije Universiteit Brussel
Lithium-based batteries are considered as the most advanced batteries technology, which can be designed for high energy or high power storage systems. However, the battery cells are never fully identical due to the fabrication process, surrounding environment factors and differences between the cells tend to grow if no measures are taken. In order to have a high performance battery system, the battery cells should be continuously balanced for ...

A Review on Multilevel Converters for Efficient Integration of Battery Systems in Stationary Applications Vrije Universiteit Brussel
Recently, multilevel converters (MLCs) have gained significant attention for stationary applications, including static compensators, industrial drives, and utility-grid interfaces for renewable energy sources. Compared to two-level voltage-source inverters (VSI) MLCs feature high-quality AC voltage with reduced harmonic content despite the lower switching frequency of the semiconductor devices. On the DC side, MLCs can integrate multiple ...

Battery voltage equalisation using single-phase cascaded H-bridge converters Vrije Universiteit Brussel
This research demonstrates modular battery storage systems’ voltage balancing using cascaded H-bridge (CHB) converters. The main principle is to maintain AC-side high-quality power absorption or injection, while on the DC-side independent battery units’ voltages get balanced. The CHB converter operates in inversion or rectification modes to discharge the storage system to an AC load/grid, or to charge it from an AC source, respectively. To ...
