Abstract
An EVSE system includes an electric vehicle supply circuit, and a timer adapted to automatically control the electric vehicle supply circuit. The timer may be adapted to enable and/or disable the electric vehicle supply circuit at one or more predetermined times. The timer may be coordinated with a scheduling system such as a calendar utility on a computer or portable communication device such as a smart phone. The system may include a user interface for the timer. The user interface may include an embedded server such as an embedded web server to enable a user to program the timer through the Internet.

10. A system comprising:
-
an electric vehicle supply circuit for providing a flow power to an electric vehicle from a power source; a controller operatively coupled to the electric vehicle supply circuit, the controller adapted to control the electric vehicle supply circuit to enable and disable the flow of power from the power source to the electric vehicle; and a timer electrically coupled to the controller, the timer adapted to send a signal to the controller to enable the controller to control the electric vehicle supply circuit by enabling or disabling the flow of power from the power source to the electric vehicle in response to the signal; and
a charge circuit interrupting device arranged to interrupt the flow of power from the power source to the electric vehicle; anda grounding monitor circuit coupled to grounding conductors, the grounding monitor unit having an output signal;
wherein the controller is coupled to the charge circuit interrupting device and the grounding monitor circuit, the controller being constructed and arranged to control the charge circuit interrupting device in response to the output signal from the grounding monitor circuit. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
