Electric vehicle battery lifetime optimization operational mode
First Claim
1. A method of setting an operational mode of an electric vehicle, the method comprising the steps of:
- displaying a plurality of user accessible operational modes, wherein a first mode of said plurality of user accessible operational modes is a Battery Life mode and a second mode of said plurality of user accessible operational modes is a Standard mode;
providing a selection means for a user to select a preferred mode of said plurality of user accessible operational modes;
displaying an indicator of said preferred mode selected by said user;
adjusting a charging maximum state-of-charge (SOC) level for a battery pack of said electric vehicle to a first maximum SOC level when said Battery Life mode is selected and to a second maximum SOC level when said Standard mode is selected, wherein said first maximum SOC level is at least 10% lower than said second maximum SOC level;
adjusting a maximum charge rate for said battery pack to a first maximum charge rate when said Battery Life mode is selected and to a second maximum charge rate when said Standard mode is selected, wherein said second maximum charge rate is higher than said first maximum charge rate; and
adjusting a maximum discharge rate for said battery pack to a first maximum discharge rate when said Battery Life mode is selected and to a second maximum discharge rate when said Standard mode is selected, wherein said second maximum discharge rate is higher than said first maximum discharge rate.

Abstract
A method of setting the operational mode of an electric vehicle is provided, where the operational mode is selected from a plurality of operational modes that include at least a Battery Life mode and a Standard mode, wherein the Battery Life mode is configured to select operating and charging parameters that emphasize battery health and battery life over vehicle range and/or vehicle performance. The system includes a thermal management system for maintaining the vehicle'"'"'s battery pack to within any of a plurality of temperature ranges, and a charging system for charging the vehicle'"'"'s battery pack to any of a plurality of minimum and maximum SOC levels and at any of a plurality of charging rates.
