Battery Electric Vehicle With Motor Cooling

This example models a battery electric vehicle with a cooling system for the motor. It is used to size mechanical, electrical, and fluid components in the vehicle. The vehicle executes a passing maneuver and the speed, torque, and temperature measurements are used to assess if the system requirements are met.

Simulation Results from Simscape Logging: With Cooling System

The plot below shows the test run with the cooling system applied to the motor. The temperature of the motor only exceeds the rated temperature for a brief period of time during an extended period of acceleration.

Warning: Excluding ColorBars, Legends and non-axes 

Simulation Results from Simscape Logging: No Cooling System

The plot below shows the test run with no cooling system applied to the motor. The temperature of the motor increases when the vehicle is traveling at a constant speed, indicating that the cooling system is needed.

The Variant Connector block was used to exclude the cooling loop from simulation without physically removing the components from the model.
