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.

Disengagement of electric vehicle charging cable

Electric vehicle (EV) charging stations for: (i) preventing damage to a battery of an EV charging station, and (ii) maintaining fast charging of the battery of the EV charging station. An EV charging station controller determines if an input power to the EV charging station is above an input power threshold value, and, if so, determines if a charge level of the battery of the EV charging station is below a low charge threshold level. If the charge level is below the low charge threshold level, a portion of the input power may be reserved for the battery of the EV charging station.
