  1. 1. Optimal torque split strategy for BEV powertrain considering thermal effects

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Dhananjay Yadav; [2021]
    Nyckelord :Optimal torque-split control strategy; battery electric vehicles; thermal model of electric machines; system identification; model order reduction; co-simulation.; Optimal vridmomentsdelningsstyrningsstrategi; batteridrivna fordon; termiska modeller av elektriska maskiner; systemidentifiering; minskning av modellorder; samsimulering.;

    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

  4. 3. Engine and Gearbox Thermal Management Modeling

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Amaury Arlotto; [2018]
    Nyckelord :;

    Sammanfattning : In order to improve the global efficiency of an engine within the French company Groupe PSA, a research axis focuses on gearbox thermalmanagement for a quicker reduction of its own friction losse after a cold start. The principle remains in deriving a little part of the coolant energy towards the gearbox – until now heated by its own internal frictions – as long as the impact on the engine warm-up is low enough for a global final gain.

  5. 4. Improvements to Thermal Management System for Automotive Components

    Master-uppsats, KTH/Energiteknik

    Författare :Tommy Enefalk; [2018]
    Nyckelord :Cooling; thermal management; energy efficiency; vehicle; automotive; Kylsystem; kylning; värmehantering; energieffektivisering; fordon;

    Sammanfattning : Global warming imposes great challenges, and anthropogenic greenhouse gas emissions have to be reduced by active measures. The transportation sector is one of the key sectors where significant reductions are desired. Within a vehicle, the cooling/thermal management system is a subsystem intended for temperature control of automotive components. LÄS MER

  7. 5. Corrosion in the coolant circuit of Pansarterrängbil 203

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Olivia Danielsson; Sonja Jonsson; Ida Mildenberger; [2016]
    Nyckelord :corrosion; galvanic corrosion; coolant circuit; water heater; aluminum; automotive; SEM; LOM; military;

    Sammanfattning : The military vehicle, Pansarterrängbil 203 (PATGB 203) demonstrates a fault. There are some components in a coolant circuit that fail due to corrosion while others are unaffected. One of the affected components that will be investigated in this report is the water heater.
