Abstract: A system and method for bi-directional direct current (DC) charging in electric vehicle supply equipment (EVSE) is disclosed. The system receives from power source managing subsystem, via plurality of power sources, electricity inputs corresponding to at least one of variable DC electricity input and relatively fixed DC input voltage comprising plurality of wide DC input voltage ranges. The system displays, via user interface associated with EVSE, selectable options to user. Further, system determines at least one of charging schema for charging operation, appropriate charging mode in plurality of charging modes, and discharging schema for the discharging operation using at least one of artificial intelligence (AI) techniques and machine learning (ML) techniques, based on power source information, and power demands. Further, the system executes, upon receiving the generated DC electricity, at least one of charging operation, appropriate charging mode, and discharging operation, based on power demands.
