Abstract
A control system for generating a modified torque command for a rotating electrical machine in a battery electric vehicle (BEV) includes a microprocessor, capable of reading executable commands stored in non-volatile memory, configured to electrically connect to an inverter, determine a rated maximum current of the rotating electrical machine, receive sensor input indicating a temperature or estimating the temperature of at least one portion of the BEV, output a modified maximum current based on the received sensor input, and generate a torque command to the rotating electrical machine based on the modified maximum current.
