Problem description:	Literature analysis on a) re-use (second life) of car batteries b) new Sodium-Ion (Natrium) batteries technological aspect: challenges and opportunities create an economic model for the cost-/benefit Use case. Nissan Leaf (1. gen) 15-25 kWh remaining battery capacity in 5-10 years - 40-80 kWh batteries from cars "battery waste" - new batteries being produced, 3-10% bad output > what to do? upcoming: NaIon batteries
Methods and Tools:	The tools and methods in this thesis are based on A set of scenario, describing the challenges A list of requirements being extracted from the scenarios A description and evaluation of technologies and tools being candidates for solutions A functional architecture/description of the envisaged system An implementation of the core concepts A demonstration of the solution An evaluation of the solution, including a critical review of the descisions taken earlier Conclusions References
Time schedule	The envisaged time schedule (for a long thesis/60 ECTS) is: T0 0 starting month, T0+m denotes the month where the contribution to a certain chapter shalle be finalized T0+2 months: create an initial page describing the scenario T0+3: Provide a list of technologies which you think are necessary for the thesis T0+4: Establish the table of content (TOC) of the envisaged thesis. Each section shall contain 3-10 keywords describing the content of that section T0+7: Provide a draft of section 2 (scenario) and 3 (technologies) T0+10: Establish a draft on what to implement/architecture T0+11: Set-up an implementation, testing and evaluation plan T0+15: Evaluate your solution based on a set of parameters, keep in mind there is no such thing as a free lunch T0+17: Deliver the thesis
Pre-Knowledge	This thesis includes a reasonable amount of programming. The envisaged thesis is based on radio communications, thus expects the user to have followed at least two radio-related courses

Depiction

this page was created by Special:FormEdit/Thesis, and can be edited by Special:FormEdit/Thesis/Evaluating the Technical and Economic Potential of Second-Life EV Batteries for Stationary Energy Storage

This page provides hints on what to include in your master thesis.

Next steps

• get UiO format (LaTeX or Word), and
• start establishing the TOC of the thesis, focus on chapters 1-3
• start describing the scenario (what to look at)
• starting point: Elicit report, with own literature
• identify more questions (to ask to Elicit)

TOC

Title page, abstract, ..., (see UiO thesis example)

1. Introduction, containing: short intro into the area, what is happening

1.1 Motivation, containing: what triggered me to write about what I'm writing about

1.2 Scientific Methods, containing: which methods are you using, how do you apply them

• Scientific Method (Wikipedia) - often: Research Questions (3-5 questions).

2. Scenario, optional chapter for explaining some use cases

2.1 user scenario, (bad name, needs something bedre)

• "old electric cars", what to do? (i) sell (ii) "as is" with a bidirectional charger, (iii) extract battery and repackage
• Solar households, who 1:2 or 1:3 in economic terms of consumption vs production. Example: buying for 150 øre/kWh, sales for 74.3 øre/kWh - if price goes down, e.g. 30 øre/kWh, then buying is about 90 øre (1:3). % calculate (how is sales / buy taxed and offered)
  • see: TEK5370 L9 costs of electricity
• ASKO, UiO, (companies) who invested into solar, need batteries

2.2 Requirements/Technological challenges

3. State-of-the art/Analysis of technology, structure your content after hardware/SW (or other domains). Describe which technologies might be used to answer the challenges, and how they can answer the challenges

3.1 state of 2nd use batteries (see 2.1)

3.2 "health of a battery" > technology, challenges

3.3 technology roadmap for NaIon batteries > expectation for NaIon

3.4 economic modelling tools

4. Economic Model for 2nd use or new battery

4.1 Baseline: for which case am I modelling?

4.2 Sensitivity analysis: "what if?" (double/half size of battery, investment costs, ...)

5. Evaluation

6. Conclusions and Future work

Comments

Red line

Your thesis should have a "red line", which is visible throughout the whole thesis. This means you should mention in the beginning of each chapter how the chapter contributes to the "goals of the thesis".

Use of scientific methods

A thesis follows a standard method:

• describe the problem (problemstilling)
• extract the challenges. These challenges should be measurable, e.g. method is too slow to be useful to voice handover.
• Analyse technology with respect to challenges. Don't write & repeat "everything" from a certain technology, concentrate on those parts (e.g. protocols) which are of importance for your problem

References

• Wikipedia is good to use to get an overview on what is happening. But there is not scientific verification of Wikipedia, thus you should use wikipedia only in the introduction of a chapter (if you use text from wikipedia). Use scientific literature for your thesis.
• Scientific library is "at your hand", you can get there directly from UiO: [[How to get access to IEEE, Springer and other scientific literature -> Unik/UiOLibrary]]
• I suggest that references to web pages, e.g. OASIS, W3C standards, are given in a footnote. Only if you find white papers or other .pdf documents on a web page then you refer to them in the reference section.

Evaluation of own work

Perform an evaluation of your own work. Revisit the challenges and discuss in how you fulfilled them. Provide alternative solution and discuss what should be done (or what could have been done).
