  • Patent number: 8655553
    Abstract: A monitoring system is for an electric vehicle and an electric vehicle supply equipment. The electric vehicle supply equipment is structured to communicate with the electric vehicle to charge the electric vehicle. The monitoring system includes a monitoring component structured to monitor communication and monitor energy or power flow between the electric vehicle supply equipment and the electric vehicle, a storage component cooperating with the monitoring component to store information corresponding to the monitored communication and the monitored energy or power flow between the electric vehicle supply equipment and the electric vehicle, and a power supply structured to power at least one of the monitoring component and the storage component.

  • Patent number: 8288958
    Abstract: A controller device and corresponding method for modifying an AC input power to provide a reduced power AC output power to a load when coupled to the controller device. The AC output power has a series of cut-out pulses in half cycles of the AC output power waveform. The device includes a switching system having a plurality of switching elements for positioning the series of cut-out pulses in the half cycles of a waveform of the AC input power to result in said reduced power AC output power; and a switch control system for coordinating opening and closing of the plurality of switching elements during positioning of the series of cut-out pulses. The switch control system includes a synchronization system for synchronizing the switching system with timing of said half cycles of the AC input power waveform; wherein the series of cut-out pulses includes at least two cut-out pulses having different durations and different positioning in said half cycles.
