System and method for managing power and efficiently sourcing a variable voltage for a transport climate control system

A transport climate control system for use in a transport vehicle, the system comprising:

• a controller configured to determine an electrical supply voltage of an electric supply equipment (ESE);
• and
• a battery pack voltage configurator circuit that includes:
• a first battery bank,
• a second battery bank, and
• a plurality of switches,
• wherein the controller is configured to control the plurality of switches based on the determined electrical supply voltage of the ESE,
• wherein the battery pack voltage configurator circuit is configured to provide a pack voltage and a pack current to charge the first battery bank and/or the second battery bank, the pack voltage and the pack current vary in magnitude based on the control of the plurality of switches.
