ENERGETIC OPTIMIZATION OF PROPULSION SYSTEMS FOR ELECTRIC VEHICLES

ENERGETISCHE OPTIMALISERING VAN AANDRIJFSYSTEMEN VOOR ELEKTRISCHE VOERTUIGEN

Various studies showed that a separately-excited DC motor provides the best combination of efficiency, performance, production cost and system reliability for a near-term electric vehicle. The research described in this thesis concerns investigations into propulsion systems suitable for electric vehicles. Preliminary investigations into the energetical aspects of electric vehicles have proved that - particularly in the case of regenerative braking - the characteristics of the propulsion system strongly influence the energy consumption. Starting from the separately-excited DC motor various drive trains are described. Simulation results for different drive trains are discussed. The main conclusions drawn from these studies can be summarized as follows: (1) from an energetical point of view a propulsion train using a variable gear ratic in general has to be preferred to a drive system with a fixed gear ratio; (2) the high operational comfort of the power train with the modified automatic gearbox is paid for with a relatively high energy consumption in comparison with the drive train using a manual gearbox; (3) the operating range appears to depend on both peak power requirement and average energy used per kilometre; so power train matching with respect to the peak power demand is strongly recommended; (4) this simulation program allows an accurate comparison of vehicle drive trains, while component deficiencies are clearly demonstrated.
