Abstract
An electric vehicle supply equipment includes EVSE control electronics, an EV connector and an HMI circuit, the HMI circuit including a proximity input terminal configured to receive a proximity signal from an EV connector indicating a state of a handle button of the EV connector, a ground terminal, a current source input coupled between the proximity input terminal and the ground terminal, a comparator connected between the proximity input terminal and the ground terminal to provide an output representing a state of the handle button when the current source is activated by the control input and an output terminal to which the output of the comparator is connected, the output terminal being connected to the EVSE control electronics, wherein the state of the handle button is utilized as an input to the HMI circuit.
