%% 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. % % Copyright 2021-2023 The MathWorks, Inc. %% Model open_system('bev_motor_cooling') set_param(find_system('bev_motor_cooling','MatchFilter',@Simulink.match.allVariants,'FindAll', 'on','type','annotation','Tag','ModelFeatures'),'Interpreter','off') %% Simulation Results from Simscape Logging: With Cooling System % % The plot below shows the test run with the cooling system applied to the % motor.
