Electric vehicle charging station (EVCS) are described. These stations can dynamically switch between different charge modes depending upon the needs of the station operator and its customers. For example, each charger of an EVCS can be switched between an independent charging mode, a parallel charging mode, a sequential charging mode and a vehicle-to-vehicle changing mode. The architectures described herein rely on DC-coupled EV chargers to provide a more efficient and lower cost approach for delivering power to vehicles while enabling different charging modes. These architectures are particularly suitable for use in fleet charging stations— charging stations installed at commercial or industrial locations that include multiple charge points—and freeway charging stations—charging stations located every 25 to 100 miles along a freeway. Using a common inverter in conjunction with multiple DC-DC converters improves the scalability of a fleet charging station at a much lower cost relative to conventional architectures.
