Claim Text:
1. A method of optimizing a set of charging parameters for a battery pack coupled to an electric drive train of a vehicle, the method comprising the step of: accepting a set of user determined travel information, wherein said set of user determined travel information is comprised of an intended departure time and an intended travel distance, wherein said set of user determined travel information is accepted by a system controller of said vehicle, and wherein said set of user determined travel information is input into said system controller by a user utilizing an input device; determining an optimal charge level for said battery pack, wherein said optimal charge level maximizes a battery lifetime characteristic of said battery pack while being sufficient to supply energy to said electric drive train for said vehicle to travel said intended travel distance, and wherein said step of determining said optimal charge level is performed by said system controller; determining an optimal charging rate for said battery pack, wherein said optimal charging rate maximizes said battery lifetime characteristic of said battery pack while being sufficient to complete charging of said battery pack to said optimal charge level prior to said intended departure time, and wherein said step of determining said optimal charging rate is performed by said system controller; and charging said battery pack of said vehicle to said optimal charge level, wherein said charging step is performed at said optimal charging rate, wherein said intended departure time identifies a first expected time of usage for the vehicle after completion of the step of charging said battery pack of said vehicle to said optimal charge level and at said optimal charging rate, and wherein said intended travel distance identifies a total expected travel distance for said vehicle to travel during a period of time occurring between completion of said step of charging said battery pack and initiation of a subsequent charging cycle.
