Overview
Motor designs cannot ignore the maximum power supply of batteries in electric vehicles because each acts as a power source to the drive motor. Energy-efficient driving must not only utilize limited power resources as efficiently as possible but often needs to maintain a certain margin below the power limit. Accurately identifying where the motor can operate within the drive cycle due to these power limits is critical to determining the feasible drive cycle.
JMAG accounts for the input and output power limits when creating efficiency maps. This enables engineers to how the power limits affect the NT curves and efficiency maps.
This case study evaluates the efficiency maps and operating points of an IPM motor during the drive cycle while accounting for the power limits.
