Week 11 : In week 11, the primary focus was researching quantitative methodology. A quantitative methodology means the process of gathering and evaluating numerical data to characterise, predict, or control relevant factors. This kind of study aids in prediction-making, examining the causal links between variables, and expanding findings to larger populations. Quantitative research aims to test a theory or hypothesis and, depending on the findings, either accept or reject it. Typically, this methodology is used to spot trends and uncover patterns in the research. Action Taken: I used the same method to acquire the definitions of quantitative methodology. Result: I finished writing my quantitative methodology by the end of the week. 

  Week 10: This week, I started to focus on just researching what is a qualitative methodology. A qualitative methodology involves collecting and analysing non-numerical data, which can help us understand concepts, opinions, and experiences. Action Taken: I have read literature from different studies explaining what qualitative methodology means. Additionally, other sources and websites provided by big-name universities also provide definitions and how this methodology can benefit the type of research I will be doing. 

Week 9: I have worked on my gap analysis for sub-aims 1 to 3.  Action Taken: I have explained and explored all the possible gaps in the literature review analysis I have done. In the same week, I started to research and read about the types of methodologies, which are qualitative, quantitative, and mixed. I have used three hours at night to read these types of methodologies. Result: I created a Gantt chart and determined a clear calendar on how I will split researching these types of methodologies in the following 4 weeks. 

Week 8: In week 8, I focused on researching and writing a literature review about current charging options and future developments for EVs. Action Taken: I have researched the current charging options for EVs. According to my literature review, different country regions have designated EV plug connectors due to grid restrictions. The photo below shows the country that utilised the type of EV charging.  Fig 12 Global EV inlet adoption (Plugshare, 2021) I have included some interesting future charging options in my literature review to see what research and technology engineers are researching. Future developments of charging options for EVs are battery swapping and wireless power transfer (WPT)

Week 7: In week 7, I carried on writing my sub-aim 2, "Investigate the operating parameter of an electric vehicle" from the previous week. Action Taken: I researched how range anxiety affects drivers' perception of EV range. However, I have found that range anxiety can be neglected in city driving. According to Mariasiu et al., 2019 research study shows the average traffic speed (km/h) in different cities.  Average traffic speed (km/h) in different cities (Mariasiu et al, 2019)

  Week 6: This week's focus is reading through all the literature reviews I have accumulated and writing my literature review analysis regarding the operating parameters of electric vehicles.  Action Taken: I have written down on a Word file all useful links to read. I have skimmed through all the links and found useful information on how the EV battery acts by the environment, driver habits, and vehicle design. For each literature review I found useful and interesting, I will look at the reference list to explore and read further what the original authors have included.  1.) Parameter design and optimization of electric vehicle 2.) Parameters influencing electric vehicle range 3.) Selection of the battery pack parameters for an electric vehicle based on performance requirements 4.) Pure electric vehicle power-train parameters matching based on vehicle performance
