This research study deals with the heat prediction of the battery in electric vehicles. An all-electric vehicle is considered in this study. The FTP-75, NEDC, and WLTC standard driving cycles are used to assess the performance of the electric vehicle battery. Additionally, the actual Munich driving travel cycle was employed in the simulation. The parameters that determine the performance of the vehicle, such as the battery's state of charge (SOC), energy consumption, and operating temperature, are evaluated. The results indicate that raising the gradients increases the temperature and the heat output from the battery. In addition, Munich's driving cycle increased driving time and rapid accelerations have raised temperatures and increased heat generation. The results showed that an increase in the road slope of 5 % results in an increase in the battery temperature of 3 % and a reduction in the SOC of the battery for 20 %. In addition, results showed that for a travel path with an average road slope of 5°, the battery temperature increases about 7 0C which requires more thermal management using hybrid cooling.
