1. Greening the grid of Indonesia - Second life application for Lithium-Ion Electric Vehicle batteries in Indonesia’s Energy System
Master-uppsats, Lunds universitet/InnovationSammanfattning : With the increasing energy demand from urban electrification, the growing economy and global warming, Indonesia has some extensive challenges ahead. Additionally, growing demand for Li-ion batteries is causing shortages of virgin battery minerals in parallel with the increasing demand for energy storage to accommodate electrification. LÄS MER
2. Reducing cost and CO2 emissions in the gasoline to electric vehicle fleet transition
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/ElektricitetsläraSammanfattning : If you buy a new electric car today it will take on average about ten years for you to start saving money compared to just continue driving your old gasoline car. It will also take about 4 years until you start saving carbon dioxide emissions, both of this is because of new production costs and emissions. LÄS MER
3. Pulse Charging of Li-ion Batteries for Enhanced Life Performance
Master-uppsats, KTH/KemiteknikSammanfattning : Det överhängande behovet av att minska utsläppen av växthusgaser för att uppfylla Parisavtalet har väckt ett ökat intresse för elektrifiering som en strategi för att mildra klimatförändringarna. Litiumjonbatterier spelar en central roll vid elektrifiering och har framträtt som det primära alternativet för batteridrivna elfordon. LÄS MER
4. Battery Storage as Grid Reinforcement for Peak Power Demands
Master-uppsats, Linköpings universitet/EnergisystemSammanfattning : An increased amount of intermittent electricity production, more electric vehicles (EV), and an overall electrification of society may all cause a higher variability between the balance of supply and demand on the electric grid. Battery storage has been identified as a solution to the emerging problem asit can be charged during hours of low power demand and then discharged to help meet the power demand during peak loads.

5. State of charge and heat impact on Li-ion batteries during calendar aging
Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Signaler och systemSammanfattning : Rechargeable batteries that are powering our everyday electronics go through their lifetime with countless charge/discharge cycles, after a few years the capacity has dropped noticeably. But how about batteries that are working as a back-up power system for when connection to the AC mains is not possible, they might only perform a handful of cycles but does this mean they last forever? On behalf of Getinge AB, this bachelor thesis aims to explore the subject named as ‘calendar aging’. LÄS MER
