Round 1

Reviewer 1 Report

Very good paper, with a logical structure and deep analysis of the topic, research question is clearly outlined.

Background study is very good, however some of the reference is older than 10 years, but authors showing development progress in that field for last two decades. anyway, appropriate key studies included and references are relevant. It is clear what is already known about this topic. The research question clearly outlined. Used methods are valid and reliable. Data and results presented in an appropriate way and conclusions supported by results.Topic is highly demanded and definitely will be interesting for the audience.

Author Response

Thank you very much for your valuable comments. 

We would like to provide more explanation on your statement: ''however some of the references are older than 10 years, but authors showing development progress in that field for the last two decades. ''.

To model the conventional microscopic fuel consumption model for transportation application, there are two main processes required. First is to estimate the driving power. Second is to construct the relationship between the driving power and fuel consumption.

To estimate the driving power, a large number of researches has been using VSP equation which was derived since 1999. To construct the model, the VSP binning method has been introduced and become popular after since 1999. Thus, this research attempts to show the modeling methodology from 1999 up until now.

Thank you again.

Response to Reviewer 2 Comments


Point 1: Define Nomenclature, Greek symbols, subscripts, superscripts, acronyms and abbreviations

separately in table form.

Response 1: We have inserted a table describing nomenclature and other symbols that were introduced in this paper. Please refer to line 436.



Point 2: In Literature review only two or three papers are discussed about electrochemical thermal

modeling. Add some more references.

Response 2: Could you please specify the three papers that relate to electrochemical thermal modeling or explain in more detail about your request? As far as we concern, TFS model does not include the electrical modeling; however, we plan to apply the electrical and battery models in the future work. The suggested papers are very interesting and substantial for electrified vehicle modeling but they focus deeply on the battery module which are not discussed and modelled in this paper. Furthermore, the approach in the suggested papers are apparently different from transportation modeling approach mentioned in this paper.

Anyways, we are very happy to hear your opinion.



Point 3: Add below two references in the Introduction section about electric and hybrid vehicle model.

1). S. Panchal, J. McGrory, J. Kong, I. Dincer, M. Agelin-Chaab, R. Fraser, M. Fowler,

“Cycling degradation testing and analysis of a LiFePO4 battery at actual conditions”,

2). Panchal, S., Mathew, M., Dincer, I., Agelin-Chaab, M., Fraser, R., & Fowler, M.,

electric vehicle under actual drive cycles”, Electric Power Systems Research, Part A,

2018, 18-27.

Response 3: According to your request, we have tried to fit your paper into our work. Please check at line 364-369. We are confident that your works will be useful for the next version of our TFS model.



Point 4: Line 136; give the full name of CAN.

Response 4: Please refer to line 146.



Point 5: Give some more description about vehicle.

Response 5: Please refer to line 140-144.



Point 6: Did the authors include driver and passenger mass also?

Response 6: Please refer to line 155-156.



Point 7: Line 255; give more specification about Figure 6 Traction Force-Speed Based Fuel Consumption Model.

Response 7: We have inserted more explanation and discussion on Figure 6 between line 284-300. Apart from that we also added more explanations in Results and Discussion section. The modifications are labelled in red.



Point 8: Did the authors use any software for development of model? Describe.

Response 8: Please refer to line 266-267.



Point 9: In conclusion, give only main findings of your research with an appropriate value.

Response 9: We have updated the new version of the conclusion. Please refer to line 344-363.



Point 10: Check ref [1].

Response 10: Correction completed.



Point 11: Check ref [3].

Response 11: Correction completed.



Point 12: We normally do not use DOI when all authors and co-authors names are provided with volume, issue, page numbers and year. However, if you want to use, keep the same format for all


Response 12: Correction completed.



Point 13: Check ref [6] with “”

Response 13: Correction completed.



Point 14: In reference section, at some point, the authors have mentioned all authors and co-authors names, while at some point, only main author’s name and then ”” word is used. Use only one format for referencing. Check this issue throughout all references and fix them.

Response 14: Correction completed.



Point 15: Check ref [7].

Response 15: Correction completed.



Point 16: Check ref [20], volume is missing.

Response 16: Correction completed.


Point 17: Check all references one more time especially with co-authors first and last names, and volume, issue, and page numbers.

Response 17: Completed.
