Dear Linda, Thanks a lot for making such explanatory video. The contents are really good and you have explained so clearly. It will be great if you can share the slides. Let me know if it's possible.
Excellent presentation of the explation of the cooling technologies. Especially useful - to me - was the information pertaining to the deployment in the different manufacturers/models. Thank You.
This is a great video, thanks. You mentioned that if we would like to learn about more about refrigerant cooling system, we should comment. Here I did that :)
Excellent content, awesome explanation!, would you help to to post video on motor on water immersion levels and risks..if you haven’t done one I would request for the same..also I didn’t see any reference for MG zs ev in your video could you consider adding that in future… thanks for your time and contribution
Thank you for the very good explanation. Do you know which cooling system does Geely SEA2 platform uses? Also why not blow cool air like normal aircon with no worries for leaking
What type of connections are used for Liquid cooling systems? is it rubber hoses or metal pipes? where can i find more info on rubber hoses used in EVs?
please note that when >30°C, the battery performance (if we are talking power here) is actually increased, due to better chemical kinetics inside of the cell at higher temperature, however, it will degrade the cells.
@@newson1177 battery degrades with time, as long as it is assembled from the production line, it starts to degrade. temperature is related to the degradation rate.
Linda, this section is very wrong - @16:06. Project i-CoBat (M&I Materials led Innovate UK project) proved there is a lower cost for direct immersion liquid cooling, NOT A HIGHER COST. Also, the build is a simpler one, NOT one which is more complex, as you don't have to manufacture secondary systems around the pack, or integrate them into it, which also adds weight by comparison. This is a technically validated project with proven outcomes and and that project is even award winning. Also, leakage with a readily and fully biodegradable ester does not equal a "concern", either for OEMs or for consumers.
Hi Matthew, thank you for your comments. The direct immersion liquid cooling is relatively new tech, which has not been mass produced in vehicles yet. This might involve higher development and validation costs. But you are right, technology involves and it will be more competitive.
@@lingyanj7075 That is quite a big ask. I am currently working on a cooling solution for engineering project in university involving an air cooled battery pack with 18650 cylindrical cells. I'll be using Star-CCM+ to run simulations on various cell arrangements to find the ideal spacing.
It would be beneficial to include a section describing Tesla’s heat pump system. Through a valve assembly called the octovalve the heat pump system is able to move heat from area to area. From the battery to the cabin, from the cabin (AC) to the battery, from the battery to the outside environment, etc. It is able to heat and cool the interior cabin, the motors and the battery. Because it is moving heat as opposed to making heat it is much more efficient.
Begode electric unicycles in Guangdong need you! They don’t even use a BMS and their cooling system is poor. But they make popular high performance wheels.
A nice overview on the Thermal Management of the EV Battery system.
Dear Linda,
Thanks a lot for making such explanatory video. The contents are really good and you have explained so clearly.

I liked your overview very much I think you did excellent work on explaining the different types of battery cooling technology.

Dear Lingyan
You have made a very high quality training material. This is an outstanding Video
I have subscribed
Great video. It was really useful for me since I am working on the thermal management of prismatic li-ion
What kind of battery packs you work on?
Such an informative and comprehensive video! thank you so much for making this ; )

Thanks to all who make education videos
Excellent technical description! Thank you.

Very nice explanation. Reference 8 is excellent. It helped me a lot. Many thanks Lingyan!
Great information, thanks
Fantastic explain but little music may make this video more interesting..
Thank you very much for the presentation!
Excellent overview presentation!
Can you please provide the presentation file? Thank you in advance
Hi, can you share more details of the direct liquid refrigerant type battery cooling system, thank you 🙏
Thanks for such a detailed video on BTMS.
Very nice explained, thank you very much😄
Very nice presentation! Congrats on the fine job.
Very useful presentation. Thank you so much!

thank you I will check that.
I read that battery degradation begins when the ambient temperature is >35°C

An informative video to understand logic of battery cooling, thank you👍
Thanks, Linda, could you please share this presentation with us?
This was extremely helpful.
Thank you 🙏🏻
In ambient below 10 degrees, how the direct refrigerant system keeps the battery warmer.
Good question. For heating, BMW i3 battery heats itself - it has a resistive heater element that is powered by electricity from the battery.
你好，你是在Dana，Valeo，Mahle( BEHR) 设计电池冷却的工作吗？
Thanks Linda!

Excellent linda👍 💕
Are you in Buffalo,NY?
yup
please make a video on thermal analysis using different software
such as?

@@thedillestpickle that is a good one - you can probably find some tutorials better than what I can do :)
@@thedillestpickle cosmol physics
@@thedillestpickle have you considered the constrains for your project
Thanks for nice presentation.
I thought liquid cooling would make a better waterproof system since we would be able to apply a sealed enclosure now.
any training center with placement
Nice video, good job!
Awesome thanks!!
which masters should i study , if i want to pursue a research job in this field?
Mechanical engineering focusing on heat transfer and thermodynamics

the video image is too poor, you need to fix it more

consider getting a decent microphone ...
Sorry, I need Language Management System (LMS)..))
you are cute. I love you
Thank you so much
