  • MULTI-VOLTAGE CHARGING APPARATUS
    Publication number: 20230420935
    Abstract: A charging apparatus includes a charging terminal, a ground terminal, and a coupling circuit coupled to the charging terminal. The coupling circuit is configured to sense a charging voltage applied to the charging terminal and to selectively couple the charging terminal to a first charging node in response to a first voltage being applied to the charging terminal, and to selectively couple the charging terminal to a second charging node in response to a second voltage being applied to the voltage sensing terminal, the second voltage being different from the first voltage.
    Type: Application

  • Multi-voltage charging apparatus
    Patent number: 11764574
    Abstract: A charging apparatus includes at least one housing including a compartment, an access door connected to the housing and covering the compartment, the access door being movable from an open position to a closed position, a releasable latching mechanism configured to latch the access door in the closed position, a charging terminal in the compartment, a voltage sensing terminal, and a door release circuit coupled to the voltage sensing terminal and to the releasable latching mechanisms and configured to sense a charging voltage applied to the voltage sensing terminal. The door release circuit is configured to selectively unlatch the releasable latching mechanism in response to a voltage within a predetermined voltage range being applied to the voltage sensing terminal.
