Abstract
A charge demand controller device for electric vehicles or the like, preferably for installation with an existing residential electrical control panel, connects between a main switch and the electrical control panel made to operate at a maximum amperage value. The device includes a controller unit that constantly monitors an actual total load current at the input line connector from the main switch, and selectively operates a load switch controlling an electric vehicle supply equipment (EVSE) upon the actual total load current being above or below a trip value being a predetermined safety ratio of the maximum amperage value.
