This paper proposes a semi-active battery/supercapacitor (SC) hybrid energy storage system (HESS) for use in electric drive vehicles. A much smaller unidirectional dc/dc converter is adopted in the proposed HESS to integrate the SC and battery, thereby increasing the HESS efficiency and reducing the system cost.
High power storage and high energy storage are cascaded in the series architecture along with a power converter to isolate it from the DC bus. Since this topology requires the power converter to meet the HESS''s overall power rating, it is frequently disregarded [ 55 ].
The first method is to connect bulky electrolytic capacitors or L-C filters on the DC bus in parallel, which is the most widely used. POWER management and control of a photovoltaic system with hybrid battery-supercapacitor energy
