  • Patent number: 12263799
    Abstract: A vehicle power supply system (100), comprising: —a vehicle battery (111) with a charging voltage, —a DC-to-DC converter (130) comprising two first connection terminals (110) connected to the vehicle battery (111) and two second connection terminals (120) for connecting an external charger to recharge the vehicle battery (111) or for connecting an external battery to be recharged, wherein, in a first mode in which an external charger is connected to the two second connection terminals (120), the voltage V2 between the two second connection terminals (120) is an input voltage of the converter and the voltage V1 between the two first connection terminals (110) is an output voltage of the converter, wherein, in a second mode in which an external battery to be recharged is connected to the two second connection terminals (120), the voltage V1 between the two first connection terminals (110) is an input voltage of the converter and the voltage V2 between the two second connection terminals (120) is an output volta

  • 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.

  • 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.
