  1. 1. Evaluation of real drive data of a refuse fuel cell truck

    Master-uppsats, KTH/Kemiteknik

    Författare :Hampus Eurén; [2023]
    Nyckelord :Fuel cells; hydrogen; refuse truck; accelerated stress test; degradation; Bränsleceller; vätgas; sopbil; accelererat åldringstest; åldring;

    Sammanfattning : Ett konsortium bestående av Scania, JOAB, Powercell, KTH och Renova samarbetade för att designa och konstruera en bränslecellsdriven sopbil inom ett FFI-finansierade projekt. Sopbilen har sedan dess varit i drift i Göteborg från 2020 till 2023, med en vätgasinfrastruktur bestående av en tankstation vid tidpunkten för detta arbete. LÄS MER

  3. 2. Ageing of NCA/Graphite-Silicon Cells : Investigating the feasibility of accelerated ageing

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

    Författare :Gustav Giske; [2022]
    Nyckelord :;

    Sammanfattning : Reliable test data on cell ageing is important to have when deciding on which cell to use in a vehicle. Accelerated ageing could, if performed in a good way, increase the amount of information about the cell ageing in an early stage of a vehicle project, reducing the risk of costly battery replacements.

  4. 3. Simulation of road slope with brake applications on horizontal ground

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Ivar Rockström; [2020]
    Nyckelord :Brakes; Simulation; CAN-bus;

    Sammanfattning : During some operations the brake system on a truck is exposed to severe stress and hightemperatures. To ensure function and safety during these operations, Scania test thebrake system both test rigs and in actual trucks around the world. LÄS MER

  7. 5. Performance and Improvement Investigation of Accelerated Temperature Change Test.

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Författare :Vandana Narri; [2018]
    Nyckelord :;

    Sammanfattning : This thesis is focused on Accelerated Temperature Change Test (ATCT). This test is performed in order to deteriorate and age a product in a faster than natural way. The ATCTs are primarily controlled with four parameters: the temperature range (∆T), ramp rate (RR), dwell time (DT) and number of cycles in test ( . LÄS MER
