  • Vehicle power management utilizing operator schedule data
    Patent number: 9739624
    Abstract: An electric-vehicle power management system including a processing hardware unit and multiple modules executable by the processing hardware unit. The modules include a calendar module configured to, by way of the processing hardware unit, obtain a user itinerary indicating multiple appointment locations to be visited by a user of an electric vehicle and associated times to visit the appointment locations. The modules also include a routing module configured to, by way of the processing hardware unit, determine optional routes connecting the appointment locations indicated by the itinerary, and a vehicle-energy module configured to, by way of the processing hardware unit, predict states of charge, or changes in state of charge, for the vehicle in connection with the optional routes, yielding state-of-charge predictions. The routing module determines selected routing based on the state-of-charge predictions from the vehicle-energy module.
