Abstract
An energy storage module (ESM) assembly, ESM and method of balancing current flow on a direct current bus are provided. The ESM assembly includes a bidirectional DC-DC converter, an ESM having first and second energy cell strings connected in parallel relative to one another and configured to be connected to respective inputs of the bidirectional DC-DC converter. The ESM is configured to absorb current from the bidirectional DC-DC converter when the bidirectional DC-DC converter is operated in a buck mode. The ESM is configured to source current to the bidirectional DC-DC converter when the bidirectional DC-DC converter is operated in a boost mode.
