    Författare :Alec Chamberlain; Harald Larsson; Louise Nilsson; Daniel Vasquez; Samir Schouri; Elin Myrsell; Sally Walin; [2019]
    Nyckelord :Resistance spot welding; laser beam welding; ultrasonic welding; battery cell; electrical performance; weld quality; cost analysis; automation degree; production yield;

    Sammanfattning : The demand for high energy battery assemblies is growing in sectors such as transportation. Alongwith it is the need for reliable, efficient and cost-effective ways to electrically connect the batteries toensure their performance. Battery cells are most often put into modules or packs when produced forelectrically driven vehicles. LÄS MER

  2. 2. Applied State of Health Estimation Methods for Lithium-ion Batteries

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Simon Malmberg; [2019]
    Nyckelord :Litium-ion State of health battery batteries Estimation method Alelion;

    Sammanfattning : The ongoing shift towards a sustainable transportation sector is a hot topic. Lithiumion battery technology has become a key element in electrification due to its highenergy density and favourable electrical properties. The non-measurable chargeandhealth states of a battery are desirable to estimate for safety, performanceand economic reasons. LÄS MER

  3. 3. Sodium trapping in aluminium current collectors

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Strukturkemi

    Författare :Ville Nyström; [2019]
    Nyckelord :Na; sodium; trapping; current collector; Al; aluminium; glyme; diglyme;

    Sammanfattning : The aim of this master thesis was to establish if sodium is trapped in aluminium current collectors, which in turn could affect the capacity fade in sodium-ion battery systems. In the case of lithium-ion batteries, previous studies have shown that a trapping mechanism, where lithium diffuses through the active material and current collectors, can explain the capacity fade observed for several systems.

    Sammanfattning : Over the past few years, the interest of remote wireless sensor networks has increased with the growth of Internet of Things technology. The wireless sensor network applications vary from tracking animal movement to controlling small electrical devices. LÄS MER

  5. 5. SOLENERGI FÖR JORDBRUKSNÄRINGAR : Ekonomiska förutsättningar för jordbruksnäringar för installation av solcellsanläggningar

    Uppsats för yrkesexamina på grundnivå, Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Författare :Hampus Jansson; [2019]
    Nyckelord :;

    Sammanfattning : The purpose of this project is to analyze the economic parameters that affects the profits from a roof mounted solar cell installation for an agriculture company in Sweden. To analyze the different production type and the impact of the fraction self- used electricity is calculated with respect to the direction of the installation. LÄS MER
