1. A power management system having electromagnetic compatibility containment comprising:

  • a first module having walls that define a first generally enclosed area, said first module having circuit means for supplying power required to operate a device of interest, said circuit means being contained within said first generally enclosed area;

    a line current input cable in communication with said circuit means and extending from said first module for connection to a source of power;

    a battery current input cable in communication with said circuit means and extending from said first module for connection to a supply of direct current;

    an output current cable in communication with said circuit means and extending from said first module for connection to said device of interest;

    a second module having walls that define a second generally enclosed area, said second module being adjacent to said first module and having battery management circuitry in communication with said circuit means via said battery current input cable, said battery management circuitry being contained within said second generally enclosed area; and
