  • Publication number: 20240067014
    Abstract: In order to ensure safe and reliable disconnection of charging cables from electric vehicles during occurrence of error conditions preventing normal disengagement of such charging cables, the systems and methods disclosed herein provide a vehicle charging system including a system controller configured to present via a display a user-selectable manual disconnection option when the vehicle is not receiving a charging current, receive an indication of a user selection of the manual disconnection option, and control a charge controller of the vehicle charging system to reset in order to terminate any charging session and to disengage the charging cable. In some embodiments, the charge controller may be configured or controlled to send a session termination signal to a vehicle charge controller of the vehicle either before resetting or as part of a startup process.

  • Publication number: 20230033955
    Abstract: A vehicle charging apparatus is described herein, which may include a battery pack comprising a plurality of individual batteries, a power input port receiving electrical power at a first wattage, an AC-to-DC conversion circuit configured to provide DC power to charge groups of batteries in the plurality of individual batteries, a power conversion circuit configured to condition a DC output of at least one group of batteries to provide a charging current output to a vehicle via a coupling, and a processing circuit configured to control the power conversion circuit to provide the charging current at a second wattage greater than the first wattage. The first wattage may be actively or inherently limited to a level less than the second wattage in order to provide fast DC charging with a limited power input.
