Many modern electric vehicles use hybrid energy storage systems, which combine multiple energy sources. Because of their rapid charge and discharge cycles, high power densities, longer lifespans than batteries, and resistance to stress, supercapacitors (SCs) are the best option for HESS when combined with batteries. In order to improve the independence of electric vehicles, SCs are used as energy storage devices during sudden power changes and to recover braking energy. In this paper, a speed management strategy is implemented to improve the performance of electric scooters by providing the necessary power from load and power recovery during braking or counter -load. This tactic relies on a so-called ON/OFF control technique to measure the SC and battery's power sharing. To evaluate the effectiveness of the electric scooter's control strategy and the system's energy management under varying loads, a MATLAB/Simulink model has been created. The findings demonstrate that using a super capacitor alleviates the electrical strain placed on the battery.
