In this paper. a hybrid electric power supply system for an electric vehicle (EV) is investigated. The study aims to reduce electric stress on the main energy source (fuel cell) and boost energetic performances using energy sources with high specific power (supercapacitors. batteries) for rapid traction chain solicitations such as accelerations. https://www.ealisboa.com/best-flash-Nightstick-TWM-850XL-Tactical-Weapon-Mounted-Light-limited-super/
