Abstract:
1. A multi-mode operating system for an electric vehicle, comprising: a battery charging system for charging a battery pack of said electric vehicle, wherein said battery charging system charges said battery pack to any of a plurality of maximum and minimum state-of-charge (SOC) levels, and wherein said battery charging system charges said battery pack using any of a plurality of charging rates; a thermal management system coupled to said battery pack of said electric vehicle, wherein said thermal management system maintains said battery pack to within any of a plurality of temperature ranges; a vehicle control system coupled to said battery charging system and to said thermal management system; and means for selecting a vehicle operating mode from a plurality of operational modes controlled by said vehicle control system, wherein said plurality of operational modes includes at least a Battery Life mode and a Standard mode, wherein said selecting means is accessible by a user of said electric vehicle, wherein said Battery Life mode utilizes a first maximum SOC level during battery pack charging that is at least 10% lower than a second maximum SOC level utilized in said Standard mode, wherein said Battery Life mode utilizes a first maximum charge rate and said Standard mode utilizes a second maximum charge rate that is higher than said first maximum charge rate, wherein said Battery Life mode utilizes a first maximum discharge rate and said Standard mode utilizes a second maximum discharge rate that is higher than said first maximum discharge rate.
