1. An integrated electric meter and electric vehicle charging station (EVCS) comprised of:

  • an enclosure, wherein said enclosure substantially encloses;

    an electric meter, wherein said electric meter comprises;

    at least one metering microcontroller, wherein said metering microcontroller is configured to separately measure electrical consumption of one or more electrical loads;

    one or more current transformers (CTs) and one or more potential transformers (PTs), wherein the one or more CTs and the one or more PTs provide current and voltage signals to the at least one metering microcontroller for measuring the electrical consumption of the one or more electrical loads; and

    a network interface operably connected with the metering microcontroller, wherein the network interface enables bi-directional communications with the metering microcontroller over a network;

    an electric vehicle charging station (EVCS), wherein the EVCS comprises;

    a charging contactor; and

    a charging controller operably connected with the network interface and the charging contactor, wherein the charging controller is configured to;

    control the charging contactor;

    detect whether a charging cable is connected to an electric vehicle (EV);

    determine a level of charge of a battery of the EV; and

    manage a programmable charging schedule for the EV;

    a plug, wherein the charging cable is connected to the EVCS and the plug, and the plug attaches the charging cable to the EV.
