Can it have a more specific title?
editOverall well written article, with a lot of references! The only thing I felt was about the title. I expected it to be a general article about equivalent-circuit modelling in electronics, but it turned out to be specifically about Li-ion cells. Having "cell" or "li-ion" somewhere in the title could have helped, but I am not sure. A Google search yielded many fields with closely similar names. The article also links to the Equivalent circuit page at the end. Is this the scientific term used for this field? Shivaprsd (talk) 12:55, 12 July 2024 (UTC)
- Thank you for reviewing my article!
- I was undecided on the right title. Two out of three reviewers suggested to make it more specific, so I'll implement this change for sure. I'm going to call it something like "Equivalent circuit model for Li-ion cells". Triv97 (talk) 13:48, 12 July 2024 (UTC)
- Perfect! I suggest you also notify the name change to the tutors, they might want it changed also in the course page. Shivaprsd (talk) 14:15, 12 July 2024 (UTC)
- Done! title changed under their supervision. Thanks again Triv97 (talk) 14:46, 12 July 2024 (UTC)

Repeated citations
editOK this is minor nitpicking, but in the section RC Parallels, all the three sentences of the paragraph cite the same reference. May be you need to cite only once at the end? Shivaprsd (talk) 13:00, 12 July 2024 (UTC)
- Fixed! Thank you! Triv97 (talk) 13:44, 12 July 2024 (UTC)
Well done, it very readable despite the technicalities
editI enjoyed reading, also fixed a few typos. I would double to proposal of choosing a more specific title about battery modeling or make the article more general and less battery-oriented. Not sure about the formulas, but many concepts seem to be generally applicable to other electrical equivalency models.
It was a surprise to see this topic was missing or not separately described in wikipedia. đ LuKePicci (talk) 13:08, 12 July 2024 (UTC)
- Thanks a lot for reviewing my article!
- I'm going to change the title (other reviews suggested the same).
- Unfortunately, many sections (open-circuit voltage, internal resistance, identification procedures) are strictly related to Li-ion batteries, so I think it is complicated -and outside the scope of my article- to generalize it to any electrical circuit. Also, there is already a very generic item: Equivalent circuit. Triv97 (talk) 13:54, 12 July 2024 (UTC)
Review n. 3
editThe article is well written. I know very little about batteries, however I was able to understand the topic since the author has a great capability of explaining in a simple way topics that I believe to be very technical. I fixed some minor typos, which are more than expected in such a long article. Good job! --Paneappenasfornato (talk) 13:13, 12 July 2024 (UTC)

Observations and suggestions for improvements
editThe following observations and suggestions for improvements were collected, following an expert review of the article within the Science, Technology, Society and Wikipedia course at the Politecnico di Milano, in July 2024.
Some comments that may help deepening some crucial points of the article: 1. ECMs not only simulate the voltage dynamics as reported in the article, but in general they link internal electrochemical parameters to the external macroscopic electrical behavior depending on the technique employed to test the cell. 2. I suggest to double-check (or maybe using a different reference) the figure showing OCV vs SOC: OCV should increase as SOC increases from 0% to 100%. 3. The model with passive components could be more realistic if SEI resistance and Warburg mass transfer contribution are added. 4. Please explain what is the polarization resistance that is mentioned in the section "Model equations" (it is different from ohmic resistance). 5. Please remind that capacity is not capacitance. In the article you used Q for capacity and C for capacitance. Corrections are needed in order to be consistent in the whole text. 6. Many models use CPE (Constant Phase Element) instead of capacitance C to account for the non-ideal contribution of the electrodes.
