@rajeshmohan7881العام الماضي Completely a new field , explained in very clear and depictive manner.

@prajeethkodru1930منذ 3 سنوات Thankyou, explained BMS in a simple and crisp manner. Keep it up!!

@mohammedfayad4395منذ 3 سنوات The best videos i saw about BMS. I really enjoy watching your videos. Please dont stop
@

@mustafaglnr8780منذ 3 سنوات really instructive for beginner in basics, That's why l will recommend it to all networks.
@

@muinmohammadmozammel281منذ 3 سنوات Very much informative and well narrated. Thanks a lot.

@vinayventura5785منذ 2 سنوات Nice video - one question, here what is small PCBS over the cells (voltage and discharge monitoring circuit) 2

@bobbyshaftoeقبل 11 أشهر Does the Distributed BMS topology allow for safer and longer operation of unbalanced cells?
The use case is as such: if each BMS manages the health id="hidden2" class="buttons"> along with the voltage & current output for each battery, then the "shared voltage buss" will present a "sum" voltage of all the various voltages on that master buss [that variation should not be substantial].
This allows for the safe and practical repurposing of used batteries.
How would you do this? ....وسعت

@suntzu6122قبل 6 أشهر So every single battery pack gets a thermister (not sure how to spell) tk check temps?

@user-hx1cz8lm2sمنذ 3 سنوات Nice video, it was well put together. I have a question though, I want to get 10 Battery modules that consist of 12 cells in series for each module. my id="hidden3" class="buttons"> understandings are that a BMS is mainly for cells in series. so would I be able to get away with just 1 BMS for the entire 10 modules if i run them in series? Wouldnt that be equivilant to 120 cells in series? I would just need 1 BMS that can handle 120 cells in series instead of getting 10 individual BMS for each module? ....وسعت 1

@sergiomartinez4146منذ 3 سنوات Great video!
Where did you get that knowledge from?
Is there any recommended book to go deeper in this topic?
@

@annanyatyagipمنذ 3 سنوات Thank you! So does the centralized topology not use a BMS? 1
@

@dineshs6750منذ 4 سنوات How centralised..? By measuring the amount of voltage using ADC and calibrating according to that..?

@xXZ31t6esTXxمنذ 4 سنوات Do you about good realible BMS for a car conversion? 1

@PhonetoysTvمنذ 3 سنوات sir what happen if i use 12.6 full charge battery bank but my charger is only 12 volts. i use 10amp bms, 3 pcs 18650 battery in series =12.6v. the battery id="hidden4" class="buttons"> will be always on charging state, right? because it cannot reach 12.6v full charge so the bms will not cut the charging because the charger is only 12volts. what will happen to battery? ....وسعت

@ibrahimabdulmaleek1058العام الماضي Is it possible to use to 2 slave card and 1 master card for a 12 cell battery pack

@thatonebeoneمنذ 2 سنوات i dont use a bsm for my trolling motor i just monitor it with a cell checker.. its 100ah but i only use like 30ah to 40ah after fishing for about 4 hours id="hidden5" class="buttons"> is what i do the most.then i balance charge it..easy to manage but if im going to have a other type of home use i would use a bsm because i dont have to worry about it and check it. i let the bms do the work.. with trolling motor i can see the cells voltage and manage my power use..im using grade a cells 4s. im using close to half the capacity of my battery most all the time when i fish.. iwas thinking of a 200ah size but it will be useless as i dont even use up all my 100ah battery ....وسعت

@corneliussianturi476منذ 3 سنوات actually about BMS
it's not efficien for example 10P 8S
and using only 1 BMS Only, my thought was about faulty change was high id="hidden6" class="buttons"> />how about use BMS every 1 pack of BMS
that I mean 8S and 1P of battery that has 1 BMS
so 8S and 10P has 10 BMS on it for more acurate discharge and charge reading parameter ....وسعت
