Abstract: An electric vehicle charging system comprises one or more system power and control modules (SPCM) and vehicle charging stations (VCS); wherein the SPCM distributes power from a power source to the VCS, and the VCS distributes power to one or more electric vehicles. Another electric vehicle charging system comprises an SPCM, VCS, a fleet management system (FMS) for monitoring and controlling the charging system, and a communications network for sharing information. A system for managing a plurality of electric vehicles comprises a plug-in module configured to collect and store information from an on-board diagnostics system of at least one of the plurality of electric vehicles, management software, a communications network, and a smart device software application for displaying system information. A computer-readable medium having computer-executable instructions for supporting a management system for a plurality of electric vehicles to extract, organize, and display information from the management system.

Abstract: An enclosure for deterring the transmission of electromagnetic radiation therethrough comprises a housing, a door and a plurality of fingers that extend from the door. The housing has an opening for holding electronic equipment. The door is coupled to the housing and has a periphery. The housing, door, and fingers are conductive. When the door is in a closed position, the plurality of fingers on the door contact the housing.

Abstract: A circuit board enclosure for housing a plurality of circuit boards has a polymer casing having upper and lower openings and an interior. The circuit board enclosure also has upper and lower heat conductive pieces formed of a metal and fitting respectively within the upper and lower openings in the casing, in a water tight sealed relationship with the casing. The upper and lower heat conductive pieces have heat transfer fins protruding from the openings in the casing. The upper and lower heat conductive pieces have an interior side facing the interior of the enclosure. The interior sides have guide grooves to receive opposing sides of the circuit board. The guide grooves of the upper and lower heat conductive pieces are substantially parallel. The polymer casing may be formed of polycarbonate. The upper and lower heat conductive pieces may be formed of aluminum.

Abstract: A heat exchanger for passive heat exchange between a weather-tight, sealed electronics cabinet for exchanging heat between a heat generating side of a separating plate and an exhaust side of the separating plate is provided. The heat exchanger includes at least one layer of heat exchanger fins running in a first direction, on the heat generating side of the separating plate. The heat exchanger also includes a plurality of layers of heat exchanger fins running in a second direction, generally perpendicular to the first direction, on the exhaust side of the separating plate. The heat exchangers are sealed with a continuous gasket in the top of a cabinet housing electronic equipment.
