1. A system for charging at least one battery and comprising:

  • a power and data communication bus comprisinga plurality of AC power lines to distribute AC power from an AC power source,a plurality of DC power lines to aggregate DC power to the at least one battery,a plurality of data communication lines, anda plurality of modular ports each coupled to the plurality of AC power lines, the plurality of DC power lines, and the plurality of data communication lines;

    a plurality of charging power modules each coupled to a respective modular port of the power and data communication bus;

    at least one inverter module coupled to a respective modular port to convert DC power from the at least one battery into AC power and provide the AC power back to the AC source; and

    a central controller configured tocommunicate with the charging power modules and the at least one inverter module through the plurality of data communication lines of the power and data communication bus,identify the charging power modules and the at least one inverter module coupled to the modular ports, along with respective functions and power ratings associated therewith, andselectively control the charging power modules and the at least one inverter module based upon their identified functions and power ratings to charge the at least one battery via the DC power lines and provide AC power back to the AC source.
