1. A vehicle charging system for charging a vehicle, comprising:
a power input port configured to receive input electric power from a power source at a first voltage (V1);
a plurality of batteries configured to receive a direct current (DC) input current derived from the input electric power received at the power input port and store electric power from the DC input current;
a vehicle coupling configured to receive a DC charging current at a second voltage (V2) derived from at least a first battery of the plurality of batteries and to provide an electrical interconnect between the vehicle charging system and the vehicle in order to provide the DC charging current to the vehicle;
a resilient power subsystem configured to provide a DC operating current at a third voltage (V3) derived from electric power stored in at least a second battery of the plurality of batteries to a plurality of system components within the vehicle charging system, wherein the system components are configured to control operation of the vehicle charging system; and
a system controller of the plurality of system components, the system controller comprising one or more processors configured to:
receive the DC operating current during a time interval in which the input electric power is not being received from the power source; and
control the vehicle charging system to provide the DC charging current to the electrical interconnect to charge the vehicle during the time interval.
