Abstract: Supercapacitors (SCs) are still considered as emerging storage devices. However, the combined operation of SCs and Li-ion batteries, forming hybrid energy storage systems (HESS), has shown real world feasibility, especially in electrified transportation. Thus, this paper is purposed to propose a simple small-scale model of a SC in EV’s drivetrain system. Two scenarios are considered – SC replacing Li-ion battery as the first scenario and the second scenario consisting of including SC in tandem with Li-ion battery (HESS). Obtained results are as expected, i.e. SCs being less inert than batteries react faster to the transients whenever regenerative braking occurs.
