a first power supply unit that supplies power for the integrated meter;

an auxiliary power out connector that interfaces with a circuit board of the EVSE and that carries power to a second power supply unit of a charging unit of the EVSE;

an auxiliary power in connector that interfaces with the circuit board of the EVSE and that carries power to the first power supply unit and the second power supply unit through the auxiliary power out connector;

a current transformer coil that includes an opening that allows input power to be passed through the integrated meter through a conductor, wherein the input power is split into a main path and an auxiliary path, wherein the main path is for charging an electric vehicle connected to the EVSE, wherein the auxiliary path feeds the first power supply unit and the second power supply unit, and wherein power of the auxiliary path passes through the auxiliary power in connector and then the opening of the current transformer coil in reverse before being passed to the first power supply unit and the second power supply unit through the auxiliary power out connector to remove any current not for charging the electric vehicle from current measurements; and

a processor that calculates energy measurements for charging the electric vehicle connected to the EVSE, wherein the calculated energy measurements for charging the electric vehicle only include current drawn by the electric vehicle.
