1. 1. Jämförelse mellan energilagringstekniker, samt dimensionering av batterier och vätgaslagring i off-grid system med solceller : En mjuk multikriterieanalys, samt skapandet av ett dimensioneringsverktyg som tillämpas på befintliga verksamheter

   Master-uppsats, Linköpings universitet/Energisystem

   Författare :Vendela Stenholm; Sara Sjödin; [2023]
   Nyckelord :;

   Sammanfattning : Elsystemet måste vara i balans mellan den el som produceras och den el som konsumeras, i varje sekund året om, för att undvika effektbrist. Risken för obalans i elsystemet ökar dock, delvis på grund av en ökad andel förnybar och intermittent elproduktion. LÄS MER

3. 2. Techno-economic study of second-life EV batteries as alternative energy storage and comparison with lead-acid and new Li-ion batteries in off-grid PV systems

   Magister-uppsats, Högskolan Dalarna/Institutionen för information och teknik

   Författare :Vijay Arumugam; [2022]
   Nyckelord :Second-life EV batteries; PV off-grid systems; HOMER; comparison of batteries in off-grid systems; repurpose the retired EV batteries.;

   Sammanfattning : The global EV stock is expected to increase from 7.2 million in 2019 to nearly 140 million vehicles by 2030. So, the demand for the battery also increases due to the increase in the number of EVs. LÄS MER

4. 3. Design and Development of a Data Acquisition and Communication System for Point Absorber Tracking

   Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

   Författare :Balakrishnan Kannan; [2021]
   Nyckelord :Data Acquisition System; Raspberry Pi; Controller; Processor; Wave buoy; Lysekil; wave energy; measurements; IMU; GPS; Strain gauge; force; Solar energy; Battery; communication; 4G; internet; Remote tracking; Shell; Python;

   Sammanfattning : The recent trend in generating energy from the waves has led to several advancements in the methods and the various research is conducted across the world, to study the behaviour of point absorbers on the waves. The point absorbers such as wave buoys are designed to move according to the waves and the generator that is mechanically coupled with the buoys, generate electricity. LÄS MER

5. 4. Evaluation of Traction Control Systems for an Electric Forklift Truck

   Master-uppsats, Linköpings universitet/Fordonssystem

   Författare :Mattias Karlsson; Sebastian Johansson; [2021]
   Nyckelord :forklift; traction control; maximum transmissible torque; model following control; sliding mode control; slip; asr; tcs; mfc; mtte; smc; electric vehicle; master thesis;

   Sammanfattning : This thesis evaluates different controllers for traction control on an electric forklift truck and has been done in cooperation with Toyota Material Handling Manufacturing Sweden. The need for a traction control system has increased with the introduction of lithium-ion batteries replacing the older lead-acid batteries, reducing the battery weight and therefore the downward force on the driving wheel increasing the risk for slip.
