  • a device may trip automatically in response to the over current condition or the short circuit condition to prevent or reduce damage to the EV chargers or the EV(s) being charged and/or may be reset automatically when the over current condition or the short circuit condition is resolved.
  • a device may be tripped manually by a person to inspect, service, or otherwise interact with the cable, the EV charger, the charger platforms, or some combination thereof downstream of the device, and may be reset manually by the person when finished with inspecting, servicing, or otherwise finished.
  • the overcurrent device 332 may include one or more fuses that each include a closed state and a failed state. In the closed state and when installed, the fuses may electrically couple the EV charger to the cable of the CMS. In the failed state, the fuses may electrically decouple (e.g., isolate) the EV charger from the cable of the CMS. When the fuses are removed, the EV charger may be electrically decoupled from the cable of the CMS. In some embodiments, the fuses may be configured to protect the cable, the EV charger, or some combination thereof from a short circuit condition or an overcurrent condition, by blowing (e.g., failing) and disconnecting the cable from the EV charger.
  • the fuses may be configured to protect the cable, the EV charger, or some combination thereof from a short circuit condition or an overcurrent condition, by blowing (e.g., failing) and disconnecting the cable from the EV charger.
  • Each fuse may be rated for a maximum current level. If a current flowing through a fuse exceeds the maximum current level (e.g., the over current condition), a portion of the fuse may overheat and may blow (e.g., melt) to create an open (e.g., the fuse may transition from the closed state to the failed state). The fuse may blow automatically in response to the over current condition to prevent or reduce damage to the EV chargers or the EV(s) being charged.
  • a fuse may be removed by a person to inspect, service, or otherwise interact with the cable, the EV charger, the charger platforms, or some combination thereof downstream of the fuse, and may be replaced by the person when finished with inspecting, servicing, or otherwise finished. If a fuse transitions to the failed state, the fuse may be removed by a person to inspect or otherwise interact with the cable, the EV charger, the charger platforms, or some combination thereof. The fuse may be replaced by a different fuse in the closed state.

Abstract

La présente invention concerne une base de socle qui peut comprendre une base de châssis et un couvercle. La base de châssis peut définir une ouverture. La base de châssis peut communiquer avec un système de gestion de câble (CMS) par l'intermédiaire de l'ouverture. Le couvercle peut communiquer mécaniquement avec un chargeur de véhicule électrique (EV). Le couvercle peut également communiquer mécaniquement avec la base de châssis. La base de châssis et le couvercle peuvent définir un volume. La base de châssis et le couvercle, lorsqu'ils communiquent mécaniquement, peuvent permettre à un câble de s'étendre entre le CMS et le chargeur d'EV et de s'étendre à travers l'ouverture et le volume.
