1. A method of distributing charging power among a plurality of charging ports of a battery charging station, wherein the battery charging station includes a plurality of power stages, wherein each power stage of the plurality of power stages is comprised of an AC to DC converter, and wherein each power stage of the plurality of power stages provides a portion of a maximum available charging power of the battery charging station, the method comprising the steps of:

  • a) monitoring a battery charging station condition and an operating condition for each charging port of said plurality of charging ports;

    b) determining a current battery charging station condition, wherein said current battery charging station condition includes current operating conditions for each of said plurality of charging ports, wherein said current battery charging condition varies over time;

    c) determining a power distribution for said battery charging station and said plurality of charging ports in response to said current battery charging station condition and in accordance with a predefined set of power distribution rules, wherein said power distribution may couple between zero power and said maximum available charging power to any port of said plurality of charging ports by coupling between zero power stages and all of said plurality of power stages to any port of said plurality of charging ports;

    d) coupling said plurality of power stages to said plurality of charging ports in accordance with said power distribution;

    e) repeating steps a) through e).
