US Patent 9517703 Electric vehicle driving range optimization system with dynamic feedback

A method is provided that aids the driver of an electric vehicle (EV) in optimizing their car's driving range. In response to the car's current driving range falling below that required to travel to a destination entered into the EV's control system, for example via the car's navigation system, the system provides the driver with one or more recommendations as to how to increase range, recommendations such as lowering top speed, altering the temperature settings of the car's HVAC system, etc. Additionally, the system provides the driver with real time driving range feedback, thereby helping the driver to evaluate the various recommendations and determine which approach is best suited to the current conditions.
