  • Publication number: 20230178927
    Abstract: A charging connector is provided. The charging connector includes a body having a first body end and a second body end. The charging connector also includes a cable connected to the first body end. The cable houses at least one conductor. The charging connector also includes at least one contact positioned at the second body end and electrically coupled to the at least one conductor. The charging connector also includes a mating interface connected to the second body end. The mating interface has a shroud and at least one contact dome that encloses the at least one contact. The at least one contact dome is at least partially formed of a first material having a first flammability resistance, and the shroud is at least partially formed of a second material having a second flammability resistance. The first flammability resistance is higher than the second flammability resistance.

  • Patent number: 11285815
    Abstract: An electrical vehicle charging device includes a power converter for receiving an AC voltage from an AC grid or a DC voltage from a DC grid, a transformer having a primary side connected to an output side, a full wave rectifier having a first input and a secondary input and a positive output and a negative output, at least two output capacitors connected between respective end taps of end taps connected in series via a center tap and between the positive output and the negative output, whereby the end taps are for providing the DC voltage to the electrical vehicle, and a switch connected in series between the first input or the secondary input and the center tap, and whereby the electrical vehicle charging device is adapted for closing and/or opening the switch depending on a DC voltage level required for charging the electrical vehicle.
