Vehicle Navigation Route Optimized for EV Charging
First Claim
1. A method of incorporating recharging stops into a driving route indicated on an on-board navigation system, said on-board navigation system integrated into an electric vehicle, the method comprising the steps of:
- calculating a current driving range corresponding to said electric vehicle; and
determining whether said current driving range is sufficient to travel to all of a plurality of locations indicated on said driving route, wherein a driving sequence corresponding to said driving route maintains an appointment sequence corresponding to an on-board calendar, wherein if said current driving range is determined to be insufficient to travel to all of said plurality of locations indicated on said driving route said method further comprises the steps of;
determining a period of time within said on-board calendar of sufficient duration to at least partially recharge said electric vehicle;
determining a recharging station location within a preset distance of said driving route and within said preset distance of a location corresponding to said period of time within said on-board calendar;
modifying said driving route to generate a modified driving route that incorporates said recharging station location; and
entering said modified driving route into said on-board navigation system.

Abstract
A method of incorporating recharging breaks into the route shown on an electric vehicle'"'"'s on-board navigation system is provided. The system initially calculates the vehicle'"'"'s driving range and determines whether the calculated range is sufficient to travel to all of the locations on the intended route. If the range is insufficient, the system may notify the user that the car should be charged the night before the intended travel day. Additionally, the system may be used to identify potential recharging stations along the intended route and, in at least some cases, confirm that the location of the identified recharging station is acceptable to the user.
