Thermal Performance of Lithium Titanate Oxide Anode Based Battery Module under High Discharge Rates

Round 1

Reviewer 1 Report

You can find here some suggestion, please correct your paper accordingly:

• explain all the abbreviations when they are first used. You use a lot of abbreviations and only a few are explained
• IR means infrared, so I suggest using another abbreviation for "thermal infrared imager" (row 67)
• fig. 1 right is not very clear, maybe you can improve it. Please try to make all the figures more clear.
• row 76 - 77 - move CCCV before charging mode
• please check that each figure has its caption under it - their placement on the page
• check the text fond size from the top of page 6
• explain all the terms of equation 1 - including m and c
• read one more time the caption from fig. 7 - one word is written incorrect
• maybe is better to use a small-capital Q in equation 1 (as is written in [20]). When one sees Q it can believe that is the amount of heat, in Joules, and that the time is missing from RI^2 formula.

1. Significance to field and specialization of “World Electric Vehicle Journal” journal: good.

The paper contains the theoretical modeling of the thermodynamic processes of the release of the thermal performance of lithium titanate
oxide (LTO) anode based battery modules under high discharge rates (both
experiment and simulation). It is found that when used in series, the battery
module with larger internal resistance generates more heat, and when used in
parallel, the battery module with lower internal resistance generates more
heat. In addition, the thermal performance can be estimated accurately with a
fast heat estimation method under different discharge rates, which uses hybrid pulse power characteristic to measure the equivalent internal resistance. With the increase of discharge rates, the chosen time- scale of calculation is smaller, and the equivalent internal resistance is smaller, while the temperature rise is higher. Thermal characteristics in the batteries zone are investigated. It is found that the highest temperature rise and temperature difference appears at 20℃, and they are 23.1 ℃ and 5.2 ℃, respectively. When discharge continues, the temperature rise and temperature difference will continue to increase. The battery modules need to be managed under higher discharges, an appropriate thermal management method that can decrease both the temperature rise and temperature difference should be proposed. Under higher discharge rates, the thermal management system should respond quickly.

2. Scientific content: good.
3. Originality: good.
4. Clarity and presentation: acceptable.
5. Appropriateness for Journal: appropriate subject mater for the “World Electric Vehicle Journal 6. Need for rapid publication: no
6. Recommendations: to sent after revision to World Electric Vehicle Journal.

Remarks

• The abstract is not concise. Please, rewrite it.
• Much more sholud evidence is need before achive the conclusions.
• Authors should make sure that they written every sentence to convey their meaning dearly to the not conclusion.
• Article should be written in an organized way.
• The manuscript should be checked by native speaker for correct grammar and spelling(for example: “20C”).
