Round 1

Reviewer 1 Report

The manuscript is a review that examines the WPT technology for use in electric vehicle applications from both the technical aspect and the environmental impact. The article has sufficient workload. The problems in the article are listed on the following aspects:

1. The texts in Figure 3 and Figure 4 are unclear and have extra spaces.

2. Table 3 to Table 8 can be described in more language to make the various structural features clearer.

3. The description of dynamic and static charging stations is not clear enough. Some parts emphasize relevant technologies of DWPT, but other parts do not mention which category the technologies belong to.

4. Missing punctuation and having irrelevant content of part 9.

5. The references should refer to more recent articles.

Reviewer 1

The manuscript is a review that examines the WPT technology for use in electric vehicle applications from both the technical aspect and the environmental impact. The article has sufficient workload. The problems in the article are listed on the following aspects:

Thanks for your constructive comments on our article and for pointing out the meritorious advantages. The paper's whole is revised as per both reviewers’ comments. Due to this, some portion of the paper are removed as per other reviewers’ comments. Hence few of the Reviewer 1 comments are not able to address completely. However, the revised manuscript covers all the important aspects in the WPT system.

  1. The texts in Figure 3 and Figure 4 are unclear and have extra spaces.

Figures 3 and 4 are removed in the revised manuscript due reviewer 2 suggestions.

  1. Table 3 to Table 8 can be described in more language to make the various structural features clearer.

Tables 3 to 8 are removed in the revised manuscript due reviewer 2 suggestions.

  1. The description of dynamic and static charging stations is not clear enough. Some parts emphasize relevant technologies of DWPT, but other parts do not mention which category the technologies belong to.

As suggested by the reviewer, the description of dynamic and static charging is included the pictorial representation in the Figure 4, Figure 5 and Figure 6. The primary side converter section is sub divided into static and dynamic WPT and explained in the revised manuscript. Moreover, the design considerations for the static and dynamic WPT is illustrated in the Figure 1.

  1. Missing punctuation and having irrelevant content of part 9.

As suggested by reviewer the punctuation error is corrected using Grammarly. The irrelevant contents are removed in the revised manuscript.

  1. The references should refer to more recent articles.

Recent references are included in the revised manuscript in reference section.

Reviewer 2 Report

The authors provide a review on WPT technologies used for EV. The paper is too lengthy, so it is hard to find what kind of challenges and its resolution exist to realize WPT for EV. Many reference papers cover general WPT technologies that are not specialized for EV WPT. The authors should consider major revision to shorten the subscript to present WPT technologies specialized for EV. In my consideration, Sections 2~5, 8, 12 can be removed in the revision because those parts are not significantly relevant to EV.

The authors should provide important trends in the EV WPT technology. As a frequency and power level are not determined at this time, it would be very helpful for readers to present what mainstream exists in the WPT industry to determine a frequency and power level.

In addition, Section 1 does not provide at the end what the authors present in this paper.

Thanks for your constructive comments on our article. As suggested by the reviewer, the length of the paper is reduced by excluding the sections 2 to 5, 8 and 12. The suggested corrected are included in the revised manuscript.

In the revised manuscript, the references which are not related to EV is removed from the reference. 

The authors should provide important trends in the EV WPT technology. As a frequency and power level are not determined at this time, it would be very helpful for readers to present what mainstream exists in the WPT industry to determine a frequency and power level.

As pointed by the reviewer, the recent trends in EV is included in section 9, page 10.

Frequency, power level and efficiency plays important role in EV WPT. Hence, a separate section (section 5) to dealt the power and frequency is included in the revised manuscript in page 6. Also, Specifications of various EV model developed in various industrial and educational departments are summarized in Table 4, in page 7.

In addition, Section 1 does not provide at the end what the authors present in this paper.

As suggested by the reviewer, the organization of the paper is included in introduction section, page 3.

Round 2

Reviewer 2 Report

All my concerns have been resolved.
