Abstract: A system for managing a fleet of electric vehicles and respective fleet drivers includes a command unit having a processor and tangible, non-transitory memory on which instructions are recorded. The command unit is adapted to obtain input variables, including respective fleet tasks and their priority status. Route data for the respective fleet tasks is obtained. The command unit is adapted to obtain an objective function defined by a plurality of influence factors having respective weights. The command unit is adapted to obtain optimal charging schedules respectively for the electric vehicles and match the respective fleet tasks to the electric vehicles and the respective fleet drivers, based in part on the objective function, input variables and the route data. The influence factors may include energy cost optimization, timeliness of task completion and minimizing range anxiety. In some embodiments, the respective weights of the influence factors are designated by a fleet manager.

Abstract: A system includes a memory device, and one or more processors for detection, characterization, and presentation of charging stations for electric vehicles. The processors determine that a charging station is an undocumented charging station; a documented charging station is one that is part of a dataset of known charging stations. A confidence score is computed to indicate whether the charging station is a public charging station. In response to the confidence score being greater than a first predetermined threshold, the undocumented charging station is documented as a public charging station. In response to the confidence score being lesser than the first predetermined threshold and greater than a second predetermined threshold, the undocumented charging station is added to a list of charging stations to investigate. In response to the confidence score being lesser than the second predetermined threshold, the undocumented charging station is documented as a private charging station.

Abstract: Battery thermal preconditioning includes scheduling thermal preconditioning in accordance with user presets, preferences and battery and/or vehicle conditions and profiles. Thermal preconditioning in advance of charging events may optimize charge time, battery health and range. Manual and predictive intelligence methods may be employed to attain and maintain a predetermined range of battery pack temperatures.
