4. Optimal torque split strategy for BEV powertrain considering thermal effects
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : A common architecture for electric vehicles is to have two electric machines one each on the front and rear axle. Despite the redundancy, this configuration ensures performance. Being energy efficient is equally important for electric vehicles to deliver a sufficiently high range. LÄS MER
5. Modeling, Simulation and Correlation of Drag losses in a Power Transfer Unit of an All- Wheel Drive System
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : A Power Transfer Unit (PTU) of an All-Wheel Drive System is a hypoid gear transmission unit that distributes the power from the vehicle transmission to all wheels of the vehicle. This thesis aims at increasing the fidelity of the analytical power loss calculation methods through test data correlation and develop a 1D simulation model that can be used to evaluate the drag losses in the PTU at early design stages.
