Amazing sir. Thank you so much for the valuable information as well as the valuable guidance as thank you so much for providing the accurate values of 21700 cell
Thank you so much for sharing valuable information I would appreciate if you Can you provide details like battery output voltage, current and rating of the battery
My graphs are giving an increasing value. What does it mean? I have followed eac step of yours, but ypu plot 3 is declining；however my plot is declining. Would appreciate your response.
Hey, thank you for the video. it was a good introduction for batteries. I want to simulate a whola battery pack for example from tesla, where we have 1584 of these cells. Does it make sense to simulate just a few like you did and then add a 3D mirror? I want also to simulate different charging and discharging rates
Hi bro.we want to work on liion battery cooling. But we don't know what exactly our professor is expecting from us in this final year project.would you suggest us anything related to thermal management system of li ion battery so that we can do our final year project successfully?
There could be a number of ways this can be interpreted honestly. For example, 1)- thermal management can be done by developing some sort of cooling channels with fluid flowing around the battery at a cell level or a module level. 2)- or you can be looking at fluid like air flowing openly across a number of cells for cooling 3)- it could be a phase change material as well that removes heat and changes its state. 4)- In channels case you study the mass flow rate or the inlet velocity and how does changing it effects the heat removal. that what i have at the moment. You can find a lot of articles online dealing with cooling channels around the cell as well as at module level that would definitely help. Actually, I am also trying to do a COMSOL simulation for thermal management of lithium ion battery using cooling channels for the past several weeks but couldn't find time to do so. Maybe if you can wait a week or so i might upload a video on comprehensive thermal management of li-batteries.
Actually it mainly depends on what you are looking to get out of the simulation this one was simpler approach and thermal analysis was the aim with least parameter implementation. The module you are talking about in COMSOL "Lithium-ion battery module" we use that one when a detailed modelling of Li-iob battery is desired. For example when you want to look into the voltage-current variation by applying constant current cycling or maybe constant voltage cycling along with the species concentration changes within the electrodes and the electrolyte.
Thanks so much I followed you step by step but in the end when I pressed on "Compute" it gave me so many errors (failed to evaluaute the expression) please help! what can I do? I'll copy the text of error in the reply
I have done this calculation with version 5.5 but when calculation is running the error occurred by (wrong number of DOFs in linearization point). Can you please help me in this regard.
Its very difficult since I never encountered this kind of error so I am sharing a link you can find the whole file of this model for COMSOL 5.5 maybe you can download that and try running that. www.comsol.com/model/thermal-distribution-in-a-pack-of-cylindrical-batteries-76291
Hello, thank you for the tutorials, i'm studying Electrical-Electronic Engineering and writing right now my Bachelor Thesis about Lithium Ion Battery modelling, @SimulationByHM is it possible to cantact you in privacy and ask you some help please? i can pay for the efforts
Sure, you can contact me through my email mhamzamurtaza95@gmail.com. But please note that I can help with the model development but you still have to get any experimental data if there is any that might be needed for the simulation.

As long as your choice of batteries are such that after mirroring, they form the whole real system then it does make sense.
Brother can you tell me the measurement for 1584 cells

@@simulationbyhm5194 yeah bro thanks .
@@simulationbyhm5194 That's what i'm trying to see. Sounds awesome work. Hope you can manage this well and share your experience with us :)
Hi Cool Work thanks for your efforts , however why did you not choose the physics study to be a lithium ion battery? there is a section for that.

@@simulationbyhm5194 okay thank you so much ❤ i will try this
Did you skip on the selection of material??
You must have missed the video 4/5
