Problems such as air pollution, shortages of oil resources and global warming have increasingly led to the use of clean and non-polluting energy sources in the industry and especially in the automotive industry. In this report, the different parts of the heat generator in an electric car such as battery pack, electric motor and car cabin (including solar thermal loads, passengers, etc.) are simulated. Subsequently, each section is verified individually by means of relevant valid papers. After ensuring the accuracy of each section's modeling, whole parts of heat generators of car are integrated. For cooling of different part, car air conditioning system has been used. Also, for cooling of battery pack and electric motor, plate heat exchangers are used. The heat transfer surface in these converters is considered as an optimization parameter and is optimized with the help of software. The heat transfer surface in these converters is considered as an optimization parameter and is optimized by means of software. After optimization, suggested integrated cooling system, is tested in Tehran driving cycle and results shoes that the battery pack temperature and electric motor temperature are between 297 Kelvin and 303 Kelvin and this period is suitable for these parts. Also, in this simulation, average cabin air temperature obtained 292 Kelvin as a suitable simulation result. In this situation, in addition to the proper operation of the battery and electric motor, the comfort conditions will be provided for car passengers. In general, the car scrolling in Tehran's driving cycle has improved by 3% and has reached 72.05 km, which has been accomplished through the use of integrated vehicle thermal management system.
