“…Therefore, existing EV Level 1 and 2 chargers still maintain a fundamental role for EV charging processes, particularly in scenarios where rapid infrastructure expansion may not be feasible or cost-effective. Level 1 and Level 2 chargers are used mainly for residential overnight charging or commercial settings, providing 110 Vac and 230 Vac with a peak power of 1.9 kW and 19.2 kW, respectively [8]. The charging process is performed in this case through On-Board Chargers (OBCs), which are dedicated to interface the AC grid with the DC battery voltage.…”

This paper presents a charging architecture for the Reconfigurable Cascaded Multilevel converter, which was specifically designed for electric vehicle (EV) powertrain applications. The RCMC topology is capable of executing power conversion and actively managing battery systems concurrently. The active battery management is achieved using the Reconfigurable Battery Module, which regulates the serial connection of cells via a switch pattern. In this paper, the RCMC is directly interfaced with an AC three-phase power system, facilitating the dynamic control over battery cells charging. Its inherent design allows for the implementation of various charging algorithms, customizable to specific requirements, without necessitating additional intermediary power stages. Firstly, an overview of the RCMC topology is given, and an analysis to define the optimal filter inductance is carried out. Subsequently, after the AC system characteristics are explained, two charging algorithms are presented and described: one prioritizes State of Charge (SOC) balancing among battery cells, while the other focuses on minimizing power losses. Moreover, a time estimation computation for the RCMC is carried out considering a two-level AC charging station. The result is compared with the time required for a conventional battery pack. The results show a reduction of 10 s in charging time for a mere 20% increase in SOC. Finally, the experimental setup is presented and used to validate the efficacy of the proposed algorithms.

“…In addition to studies focusing on the motoring phase, in which the CHB has already been extensively analyzed [7], there has been a growing area of research dedicated to the charging processes of battery modules in multilevel architectures. Multilevel converters, known for their ability to handle high voltages due to their modular design, have Energies 2023, 16, 5565 2 of 15 been widely suggested as the preferred topology for charging stations in various research works [8,9]. However, there is a relatively smaller body of research addressing battery charging algorithms specifically designed for multilevel converters in electrical powertrains.…”

The scientific literature acknowledges cascaded H-bridge (CHB) converters as a viable alternative to two-level inverters in electric vehicle (EV) powertrain applications. In the context of an electric vehicle engine connected to a DC charger, this study introduces a state of charge (SOC)-governed method for charging li-ion battery modules using a cascaded H-bridge converter. The key strength of this algorithm lies in its ability to achieve balanced charging of battery modules across all three-phase submodules while simultaneously controlling the DC charger, eliminating the need for an additional intermediate converter. Moreover, the algorithm is highly customizable, allowing adaptation to various configurations involving different numbers of submodules per phase. Simulative and experimental results are presented to demonstrate the effectiveness of the proposed charging algorithm, validating its practical application.
