16. FEM Analysis Applied to Electric Machines for Electric Vehicles
Sammanfattning : Electric vehicle technology is an interdisciplinary field in continuous development. It appears to be a margin for improvements. The Division for Electricity at Uppsala University is doing significant research in the field. The present thesis investigates electric machines for vehicular applications, both in the driveline and in the traction motor. LÄS MER
17. Design and Assessment of Battery Electric Vehicle Powertrain, with Respect to Performance, Energy Consumption and Electric Motor Thermal Capability
Sammanfattning : In this thesis, various drive cycles, legislative, official real-world and measured, have been studied and characterized based on their speed and acceleration content. Three reference vehicles (a City car, a Highway car and a Sport car) were conceptualized after performance requirements, with data on existing battery electric cars as a frame of reference. LÄS MER
18. An Interactive Traction Motors Design and Selection Software
Sammanfattning : Use of electric motors in vehicle traction, in fact, predates the internal combustion engines (ICEs). Electric vehicles powered by dc motors were known as far back as 1890. Compared with vehicles powered by ICEs, the main drawback of the early electric vehicles was, and still is, their limited range and long recharging time. LÄS MER
19. Distributed control of electric drives via Ehernet
Sammanfattning : This report presents the work carried out aiming towardsdistributed control of electric drives through a networkcommunication medium with temporal constraints, i.e, Ethernet.A general analysis on time delayed systems is carried out,using state space representation of systems in the discretetime domain.

20. Methods for motor noise evaluation and control in electric vehicles
Sammanfattning : Complete vehicle, system and component target setting for noise, vibration and harshness (NVH) are important activities within automotive product development. New challenges arise when electric motors are introduced into cars traditionally powered by internal combustion engines (ICE). LÄS MER
