The energy management system controls the operation of the energy storage system in the electric vehicle. The control strategy of the hybrid energy storage system is implemented according to a decision algorithm and based on the characteristics of the components (battery - supercapacitor). The performance of the decision algorithm is investigated by simulation performed on a hybrid energy storage system. Also, environmental parameters (temperature-slope) and driving cycles as a model of driving habits have been considered the control system's input, and the effect of these inputs on the performance of the energy storage system has been studied and eva‎luated. The results show that in almost all cycles, the supercapacitor enters the circuit in the final stages of the cycle. If we repeat the cycle, the supercapacitor is used in the circuit. The capacitor will have more charge and discharge, and also the SOC of the battery will show more reduction. Considering the values obtained in different temperature conditions, the effect of ambient temperature on SOC changes in the battery is negligible and negligible. Still, the temperature conditions will affect the durability and life of the battery. Multiple charge and discharge of the battery, which is related to the traffic pattern and driving cycle, and temperature changes over time, will be the determining parameters for battery life and durability, which reduces the battery's capacity due to the above variables. In the surveyed driving cycle of Tehran, considering the slope conditions of the route (smooth or sloping), the effect of slope and altitude difference in energy consumption is evident. This shows that for real-time investigation, it is necessary to include the instantaneous slope of the road in the calculation of longitudinal dynamics. The rate of vehicle mileage with similar conditions of battery power and capacity varies according to the type of driving cycle and the rate of cycle transient, and according to the analysis of speed charts with time in different processes, the effect of the driving process on battery life and sizing time is inevitable And it shows that about 7% of car traffic can be saved.
