    Sammanfattning : Följande studie är utförd på uppdrag av företaget Nilar som tillverkar Nickel-Metallhydridbatterier (NiMH-batterier) vid sin produktionanläggning i Gävle. Den nuvarande beräkningen av State of Charge (SoC) sker på deras Battery Management Unit (BMU) och är implementerad i Structured Text i exekveringsmiljön CODESYS. LÄS MER

  3. 2. Generating Product-Service Design Improvements from a Climate Impact and Energy Use Perspective Using Life Cycle Assessment : The Case of Vertical Access Equipment

    Master-uppsats, Linköpings universitet/Industriell miljöteknik

    Författare :Vishnu Teja Tirumalasetty; Max Olof Jonas Bäck; [2021]
    Nyckelord :Life Cycle Assessment; LCA; Product-Service System; PSS; Vertical Access Equipment; Circular Economy;

    Sammanfattning : Climate change is connected to several negative effects on local environments around the globe such as, longer, and more intense droughts, less freshwater supplies, ocean warming, sea level rise, polar ice melting, more intense storms, and rainfall (NASA, 2021).  These problems are mainly due to the increasing amount of carbon dioxide in the atmosphere as well as other greenhouse gases (GHG) which cause a similar or stronger climate change effect (WWF, 2021).

  4. 3. Method for Monitoring and Analyzing Lead-Acid Batteries

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

    Författare :Simon Chobot; Johan Hanssen; [2019]
    Nyckelord :Lead-acid battery; BMU; Current sensing; Magneto resistive; Blybatteri; BMU; Strömmätning; Magnetoresisitv;

    Sammanfattning : Lead-acid batteries today are commonly used in the automotive industry with a considerable span of purposes, yet historically, a primary purpose of cranking the engine at ignition which does demand a high current drainage from a battery. These high drainages later result in a health implication which can be hard to detect without the proper tools and this thesis focuses on the development of those tools. LÄS MER

  5. 4. Exploring Co-management : A Minor Field Study on Lake Victoria Beach Management Unit in Ggaba, Kampala, Uganda

    Kandidat-uppsats, Linköpings universitet/Tema Miljöförändring
