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.
