Abstract: EV has generally been recognised as a viable substitute for internal combustion engine-powered vehicle. The EV is capacity and lifetime of the energy storage system, leading to decreased drive range of the vehicle and rise in price. To overcome these drawbacks, dual-HESS is introduced in the EV. In this work, batteries and ultracapacitors are utilised as HESS. In this work, fuzzy control is also implemented, which is accountable for splitting the energy among the front and rear wheels units in a far more appropriate manner in order to meet the needs of greater performance. Utilising the MATLAB/Simulink software, the entire framework was built with the FTP-75 (urban), US06 (maximum speed as well as required acceleration) and HWFET (highway) driving cycles. When contrasted to a corresponding existing EV deployed with a solo HESS unit, the suggested dual-HESS architecture enhanced the driving range by 145.15 km as well minimising the HESS mass by 23.93%.
