“…Compared to [34], the results in this paper suggest a higher current THD as well as a lower PF. While the previous work achieved a THD of approximately 0.7% at 7 A, this setup resulted in a current THD of 4.5% at the same current rating.…”

“…While the previous work achieved a THD of approximately 0.7% at 7 A, this setup resulted in a current THD of 4.5% at the same current rating. However, this can be partly explained by the PR controller's lower update frequency of 16 kHz compared to 20 kHz in [34]. Because [31] only proposed the method, but didn't carry out any experiments, a comparison between the results cannot be given.…”

“…Therefore, previous studies focused mainly on the technical aspects of bidirectional converters. Currently, AC charging is possible up to 43 kW for BEVs [6,7]. AC discharging from BEVs into the power grid, however, is mostly only possible in single-phase up to a power rate of 3.7 kW [8].…”

This paper investigates the potential of bidirectional charging using modular multilevel inverter-based reconfigurable battery systems via grid-parallel control. The system offers several advantages such as modularity, scalability, and fault-tolerance over conventional battery electric vehicle systems. It is designed for seamless integration with the grid, allowing bidirectional power flow and efficient energy storage. Within this study, the battery system is first simulated in Matlab/Simulink and later implemented into a hardware setup. Eventually, the simulation results and the measurements have been compared and evaluated. Thereby, startup sequences and constant current scenarios were investigated. It has been shown that the system is fully capable to charge and discharge the batteries in the grid-parallel connection, thus enabling bidirectional charging with close to full drive system power. The current total harmonic distortion complies with grid regulations and can potentially improve the grid quality. The proposed system offers significant potential for grid-integrated energy storage systems, addressing the challenges associated with renewable energy integration, grid stability, and energy management. In comparison to other publications on this topic, the proposed approach does not need additional dedicated power electronic hardware and has more degrees of freedom for current control.
