Thermal Management of Electrified Vehicles—A Review

Round 1

Reviewer 1 Report

The manuscript has presented a comprehensive review on thermal management of electrified vehicles. It is an interesting review with the following features:   1. The review has touched several dimensions of the research in the topic.   2. The claims are well described with proper images and most of the images are well supported with datasets available from different sources.   3. The language of the manuscript suitable for the publication.   4. Sufficient number of articles are referred in the article   However, the authors must work on the following comments:   1. Figure 8, '/&' in one of the labels in the x-axis   2. It is advised to use \subsubsection() for third-level headings (if it is drafted in LaTeX). Otherwise, please update it accordingly.

Reviewer 2 Report

Comments on “Thermal management of electrified vehicles – A review”

 

As the title suggests, it is about thermal management reviews for xEVs. Modeling, simulation, and optimizations are discussed at system-level performances. The basic architecture of xEVs is presented, and component-level requirements/management are given. Subsystem components modeling is highlighted.

 

However, this review is a little broad on definitions of major xEV components. In other words, it is more like general descriptions of each xEV’s component.  The authors should explain in the review paper using further graphical results, specifically on component-level thermal management, then the optimization performances for fuel economy and emissions improvement, from those cited literature.

Since the authors would like to discuss the many scopes from modeling, simulation, and optimization, the authors may consider narrowing down the review scope from the total system-level to just one subsystem-level, i.e., powertrain subsystem, cabin subsystem, or underhood subsystem.

Then, the authors can narrow down into further details on one subsystem-level thermal management from the perspectives of modeling, simulation, and optimization. And once again, readers may want to see graphical results of the subsystem thermal management on global performances of the xEVs like fuel consumption and emissions reductions.

The reviewer understood that this request takes time to produce, but it would further improve the quality of such a review paper.

Author Response

The thermal management of electrified vehicles is an extremely broad topic and we agree that the paper covers quite a lot of different arguments. Each of them easily deserves a dedicated review paper with a much higher level of detail. The proposed paper, however, does not have the goal of deeply investigating a particular topic but its goal is to provide a broad overview of the most relevant topics. The paper is devised to introduce the reader to the thermal management of electrified vehicles. For each introduced topic a series of relevant references is given to guide the interested reader towards the required insights.

For this reason, when available, dedicated states of the art are referenced.

We, also, fully agree that a paper provifding more details at system and subsystem level should be realized, and that may be the topic of a subsequent paper.

A sentence has been added at the end of the introduction to clearly state the scope of the paper.
