  4. 2. The Four-Quadrant Transducer System : for Hybrid Electric Vehicles

    Author : Erik Nordlund; Chandur Sadarangani; Hans Kahlen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Electrical Machines; Hybrid Vehicles; Elektroteknik; Electrical engineering; Elektroteknik;

    Abstract : In this thesis a hybrid electrical powertrain called the Four Quadrant Transducer (4QT) has been evaluated through different driving simulations, which later resulted in the manufacture of a prototype. The simulation of a 12 metric ton distribution truck showed that the 4QT system can reduce the fuel consumption by approximately 30 % during the FTP75 drive cycle. READ MORE
