Planning of High-Power Charging Stations for Electric Vehicles: A Review
Round 1
Reviewer 1 Report
Abstract:
Looks like more general information. Authors should enhance the abstract by writing concise technical information related to the objective of this article.
Section 1:
The introduction section should be minimized the general points can be removed. Also, sections 1 and 1.1 can be merged and form an introduction section.
Section 2.3
Three different types of charging methods have been explained (conductive, inductive, and battery swapping). However, the reviewer felt that the literature survey regarding these methods is not sufficient. While planning the CI, the charging methods are also equally important. Therefore, this section could be improved.
Section 6:
Section 6.1 and 6.2 combined together and form a single heading "Discussion and future scope". Identified research areas can be changed. The current version of the identified research areas has not related to this topic. It is related to the discussion section. So, Kindly change it.
General comments:
- Why this review article did not focus on the revenue for the land where public CI is located.
- Can you prepare a separate section for regulation and policies regarding the CI.
- The conclusion can be improved.
Author Response
The authors are thankful to the reviewer for taking his time to review our manuscript.
The authors are also thankful for his constructive comments, observations, and corrections.
C1 Abstract: Looks like more general information. Authors should enhance the abstract by writing concise technical information related to the objective of this article.
A1: The authors carefully reviewed the abstract and implemented the constructive proposal extending and revising the content expressed.
The current version of the manuscript presents more detailed outline, structuring the charging infrastructure phases (target identification, the data acquisition and finally, modelling, allocation and sizing methodologies).
C2 Section 1: The introduction section should be minimized the general points can be removed. Also, sections 1 and 1.1 can be merged and form an introduction section.
A2: The authors are thankful for this constructive proposal: in order to implement this suggestion, sections 1 and 1.1 were merged which resulted in Introduction section with no subsections.
Introduction was also minimized to make it less detailed and some contents were redistributed throughout the article which we think will enhance readability.
C3 Section 2.3: Three different types of charging methods have been explained (conductive, inductive, and battery swapping). However, the reviewer felt that the literature survey regarding these methods is not sufficient. While planning the CI, the charging methods are also equally important. Therefore, this section could be improved.
A3: The authors are thankful for this constructive proposal and revised the paper according
to this request. Section 2.3.4 has been introduced, where high power converters are discussed.
The following articles were integrated and used in this paper to provide readers with a thorough overview of the charging schemes:
- A Review of Extremely Fast Charging Stations for Electric Vehicles
- Review of Electric Vehicle Technologies, Charging Methods, Standards and Optimization Techniques
- Electric Vehicles Charging Stations’ Architectures, Criteria, Power Converters, and Control Strategies in Micro-
- Electric Vehicles Charging Technology Review and Optimal Size Estimatio
- A state-of-the-art review on topologies and control techniques of solid-state transformers for electric vehicle extreme fast charging
This section should now provide the readers with a thorough overview of high power converters in charging stations.
C4 Section 6: Section 6.1 and 6.2 combined together and form a single heading "Discussion and future scope". Identified research areas can be changed. The current version of the identified research areas has not related to this topic. It is related to the discussion section. So, Kindly change it.
A4: The authors revised section 6 and implemented the change suggested: sections 6.1 and 6.2 were merged together in new section 6 “Discussion and future research scope”.
Instead conclusions were split apart in another section (section 7).
C5 General comments:
- Why this review article did not focus on the revenue for the land where public CI is located.
- Can you prepare a separate section for regulation and policies regarding the CI.
- The conclusion can be improved.
A5: The authors are thankful for the feedback and the questions which contributed the development of the new version of the manuscript. Following detailed answers to the general comments:
- The revenue generated from the use of land for EV charging purposes was not the main objective of the present review process (economic redistribution of the economic fluxes), indeed it, the authors mentioned that: “Land Costs: were recognized as being an important parameter [65], especially in sizing and locating parking lots for EVs [27, 28]”. Land estimation of revenue has been added as a separate topic to be further investigated in the Section 6 “Discussion and future research scope”, lines 885-887.
- Policies on charging infracture development and V2G, V2X was not directly addressed in this review, but literature reviewed shown a lack in standardization and further study is needed to create an exhaustive compendium on this topic.
This necessity which was correctly noted from the reviewer was added as a necessity for future research in Section 6 “Discussion and future research scope”
- Conclusions were divided and section 6 was extended in section 7 which should improve readability and provide the reader with a clearer structure.

3. Type of Charging Methods, Standards should be added with table format- includes all type of high power chargers
Electric Vehicles Charging Stations’ Architectures, Criteria, Power Converters, and Control Strategies in Micro-grids
4. charging behavior EV and relavent work need to be added as a separate chapter
5. Socio-economic and environmental impacts - should be discussed detailed manner
6. reference and comparative study is not enough
7. separate cheater needed to be add in the end
as “ future challenges and recommend solutions “

● Electric Vehicles Charging Technology Review and Optimal Size Estimatio
● A state-of-the-art review on topologies and control techniques of solid-state
transformers for electric vehicle extreme fast charging
Still this Suggestions are not addressed
A1:
The reviewer pointed out the need to include a discussion on “high power converters” in a separate chapter.
In order to constructively incorporate this suggestion the authors decided to upgrade the sub-sub-chapter 2.3.4 to a dedicated sub-chapter 2.4 “Power converters and architectures”, to be included under the chapter “Target identification”.
This final choice is intended to be a compromise between the reviewer’ suggestion and the authors’ point of view: after comprehensive discussion, authors have evaluated that to insert a single chapter solely on high power converters would be out of the scope of the review paper.
To include this content under the articulation of the target identification is under the objective of the authors which is to characterize the charging technologies and be able to define in detail the literature reviewed.
The authors assessed that not all the references pointed out from the reviewer were included in the first revised version of the manuscript.
Now all the reference suggested are included, as the reviewer can verify.
Namely:
● A Review of Extremely Fast Charging Stations for Electric Vehicles [line 479]
- Review of Electric Vehicle Technologies, Charging Methods, Standards and
Optimization Techniques [line 261]
- Electric Vehicles Charging Stations’ Architectures, Criteria, Power Converters, and
Control Strategies in Micro – [line 368]
- Electric Vehicles Charging Technology Review and Optimal Size Estimation [line 438]
C2 Tables inside text should be uniform
A2 The authors are thankful for the careful revision of the manuscript.
All the tables in the revised version of the review paper are now consistent with the MDPI style.
