A system for mode selective control of an electric vehicle during a race. The system may include a demand controller configured for determining a demand made by a driver during the race to control a propulsion system to propel the vehicle, a battery controller configured for determining a supply of electrical power available from a rechargeable energy storage system (RESS) to meet the demand, a temperature controller configured for determining temperature thresholds for the RESS and the propulsion system, and a supply controller configured for controlling use of the supply according to an endurance mode and a qualify mode.

Endurance mode for electric vehicle

A system for limiting performance inconsistences of an electric vehicle during a race or other circumstance when consistent, high performance output is desired, such as by enabling a driver to selectively engage endurance and qualify drive modes to control a supply of electrical power used for driving the electric vehicle.
