A New Centralized Equalizer with a Simpler Control Strategy for Series-Connected Batteries

Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

The authors have investigated “A Concentrated Equalizer with A Simpler Control Strategy for Series-Connected Battery Strings”. While the study contributes to the research knowledge, the following need to be addressed.

1.       Increase speed and voltage have been considered without the mass in the study. The authors can consider the mass issue as well.

2.       The manuscript needs to be revised by a native English speaker eg-page 5 no 175 to 179

3.       Figure 3 is repeated in Pages 5 and 6

4.       I could not see figure 5 in the manuscript making it hard to follow

5.       Figure (b) shows the experimental waves --- in Page 9 line 279 is not clear.

6.       Figure 9b is not clear enough

7.       In the references, recent studies have to be included as few or no paper from 2023 can be found in the manuscript.

Reviewer 2 Report

Comments and Suggestions for Authors

Quality of the research article is not very good. Authors need major revision.  Abstract, introduction, simulation and conclusion all needs to be revised. Authors must skip basic information and focus on their own work.  I'm not satisfied with the simulation results.

Authors must clarify the things in precise manner.

Reviewer 3 Report

Comments and Suggestions for Authors

The authors proposed a multi-mode equalizer with the concentration structure. The proposed equalizer can work in different modes: I2O and O2I. The model also flexibly deals with the imbalance in battery strings with a faster balancing speed and higher balancing accuracy. The authors first presented the hardware structure of the proposed equalizer and then discussed the working modes of the proposed equalizer. The authors also described the control strategy of the equalizer. The authors also experimented and compared with other schemes. The experiment results demonstrate the effectiveness of the proposed equalizer.

To my judgment, the authors did a very good job. Also, the presentation is very clear. Please consider the following comments to further improve.

1. What is the main challenge in this research?

2. How the proposed system is better than other strategies? Please explain in more detail.

4. How can the efficiency could be made better?

5. What about the reliability of the proposed equalizer? Please discuss more.

 

6. What about cost-effectiveness?

English is fine. But better to revise.

Reviewer 4 Report

Comments and Suggestions for Authors

The abstract needs to have some numerical data to show the comparison and efficiency of the methodology. 

The introduction is written well, and it explains the related works perfectly.

All the equations and formula must have their citation.

The paper has grammatical typos, and the conclusion must be extended and summarize the paper more scientifically. 

Overall, the paper can be considered for publication after minor revision.

Comments on the Quality of English Language

There are some typos in the context that must be fixed.

Reviewer 5 Report

Comments and Suggestions for Authors

1-     The paper necessitates a comprehensive revision to rectify the English language's typographical flaws and grammatical inaccuracies like, and not limited to in the abstrct“both the”,”this allows” is a new sentence,  

2-     Rewrite the abstract to highlight the presented work

3-     The abstract serves as a concise summary that presents overlooked aspects without emphasizing the research conducted.

4-     It is advisable to incorporate a concise overview of the findings in the abstract section.

5-     The paper does not sufficiently highlight the discrepancy between the current body of literature and the work being presented.

6-     The review lacks completeness and might benefit from the inclusion of further related work

7-     The author can see and review these papers

https://doi.org/10.1016/j.egyr.2022.09.211, https://doi.org/10.1016/j.jpcs.2022.111081

 

 

8-     “Figure 6. Control strategy of the proposed equalizer” is not clear and confusing; please redraw it as one col. not three

9-     Sources or references for all equations should be added.

10-  The y-axis title of Figure 10 should be rotated.

11-  The simulation results are insufficient to evaluate the proposed technique's effectiveness.

12-  The simulation results should be added

13-  In the case of two different types of batteries, is the proposed method is valid?

 

14- What about the cost-effective study of the proposed system

A Concentrated Equalizer with A Simpler Control Strategy for Series-Connected Battery Strings

Review

In this manuscript is presented a multi-mode equalizer with the concentration structure, which can work in inside-to-inside (I2O) or outside-to-inside (O2I) modes, to flexibly deal with the imbalance in battery strings, with a faster balancing speed, and higher balancing accuracy.

The manuscript is interesting. It is well structured and complete: contains theoretical and experimental part, and demonstrates good results.

However, a better clarity for Figure 9 (b) must be achieved.

The Conclusions regarding the “low cost” of the proposed equalizer must be explained.

Comments and Suggestions for Authors

This paper still need revision. The quality of the presentation is low and there are many typo and other grammatical mistakes in the paper. Authors can reduce the introductory material which is already well know and focus on their own work..

Comments on the Quality of English Language

Moderate changes are required
