A method is provided that gives real time feedback to the driver of an electric vehicle (EV) regarding the car's driving range, thereby allowing the driver to easily regulate battery usage, and thus driving range, by adjusting their driving style (e.g., top speed, acceleration/deceleration rates, etc.) as well as the settings of the car's various electrically powered auxiliary systems (e.g., HVAC, internal and external lights, entertainment system, etc.). |

1. A method of providing driving range feedback in an electric vehicle, wherein said electric vehicle is comprised of a battery pack coupled to an electric drive train, said method comprising:
monitoring a current battery pack charge level; determining a current driving range based on said current battery pack charge level and a predefined set of battery drainage rules; determining a first battery pack drain due to operation of said electric drive train; determining a second battery pack drain due to operation of at least one user controllable auxiliary system, wherein said at least one user controllable auxiliary system is electrically coupled to said battery pack; modifying said current driving range to yield a modified driving range, wherein said modifying step is based on said first battery pack drain and said second battery pack drain; and displaying said modified driving range on a display, wherein said display is mounted within said electric vehicle. |
