Abstract:
1. An electric vehicle multi-mode battery charging and operating system, comprising: a battery charging system for charging a battery pack of an electric vehicle, said battery charging system utilizing a cut-off voltage selected from at least a first cut-off voltage, a second cut-off voltage, and a third cut-off voltage; a battery cooling system for cooling said battery pack of said electric vehicle when said battery charging system is coupled to a charging power source, said battery cooling system cooling said battery pack to a temperature within a temperature range selected from at least a first temperature range, a second temperature range and a third temperature range; and means for selecting a preferred mode from a plurality of charging/operational modes, wherein said selecting means is accessible by a user of said electric vehicle, wherein a first mode of said plurality of charging/operational modes utilizes said first cut-off voltage and said first temperature range, wherein a second mode of said plurality of charging/operational modes utilizes said second cut-off voltage and said first temperature range, wherein a third mode of said plurality of charging/operational modes utilizes said third cut-off voltage and said second temperature range, and wherein a fourth mode of said plurality of charging/operational modes utilizes said third cut-off voltage and said third temperature range.
