Data supporting the research on Efficiency Measurements of Partial/Full Power Processing Converters and ECM Parameter Measurements for a Samsung 18650-35E Cell

The dataset includes two parts: (1) power electronics converter efficiency measurements across different operating points for both partial power processing and full power processing architectures (dual-active-bridge topology), and (2) battery characterization data, including equivalent circuit model (ECM) parameter measurements for a Samsung 18650-35E cell.
