Abstract: An electric vehicle supply equipment (EVSE) includes a thermal management system that includes a dual-sided heatsink that includes a first side that faces internal ambient air of the EVSE and a second side that faces external ambient air. A first fan circulates the internal ambient air of the EVSE across the first side to reject heat from the internal ambient air into the first side. A first airflow guide guides the internal ambient air across the first side of the dual-sided heatsink. A second fan draws external ambient air that flows across the second side to reject heat from the second side out of the thermal management system. A second airflow guide guides the external ambient air across the second side. An airflow seal prevents the external ambient air and the internal ambient air from mixing.

Abstract: A cable management apparatus of an electric vehicle charging station for managing an electric vehicle charging cable is described. The cable management apparatus comprises a housing and a swing arm. The housing houses a hub connected to a swing arm housing to allow the swing arm housing to rotate about the hub from a starting position to an ending position. The housing further houses a damper, where a first end is attached to the housing of the cable management apparatus and a second end is attached to the swing arm housing to manage retraction of the swing arm housing. The housing further houses a first rotation stop element to prevent the swing arm housing from rotating beyond the ending position. The cable management apparatus further comprises the swing arm housing connected to the housing of the cable management apparatus by the hub and the second end of the damper.

Abstract: A direct current (DC) electric vehicle supply equipment (EVSE) that includes a secure enclosure. The secure enclosure encloses a set of one or more contactors to open and close to provide DC charge transfer with one or more electric vehicles; a conductor to electrically connect the contactors with DC input; a current sensor to measure current draw; a voltage sensing circuitry to measure voltage; and one or more circuits that receive current data from the current sensor and voltage data from the voltage sensing circuitry, the one or more circuits to perform one or more safety functions and one or more metering functions using the received current data and voltage data. The DC EVSE may also include, external to the secure enclosure, a controller that is coupled with the circuits to control the opening and closing of the set of contactors.
