Abstract
An electric vehicle supply equipment (EVSE) includes a blind mate liquid quick disconnect coupler that includes a male coupling and a female coupling. The male coupling includes a pressure relief poppet valve that is positioned within the main body of the coupling. The pressure relief poppet valve controls fluid through the male coupling. The pressure relief poppet valve includes an overpressure poppet, a conical spring positioned about the overpressure poppet, and a carrier poppet that includes four prongs. The female coupling includes an opening to accept a main body of the male coupling and an end for coupling with a second fitting base of the female coupling. When the male coupling is mated with the female coupling, the pressure relief poppet valve and the tube plunger are displaced such that fluid flows between the male coupling and the female coupling.
