Public electric transport for passengers is an integral part of urban infrastructure and one of the predominant consumers of electrical energy. A significant manifestation of electric transport efficiency is the possibility of recovering part of its kinetic energy in the form of electrical regenerated energy during braking which can be accumulated in energy storage system for reuse. Current paper examines how the gradual aging of the ESS affects the efficiency of regenerated energy storage during its working lifetime by performing virtual simulations with correspondingly modified parameters based on information on the decrease of supercapacitor capacitance and the increase of equivalent series resistance. The factors causing energy losses have also been taken into account.
