Great,sirji your videos are very simple and informative, please please please make a video on Battery Brands with detailed watt & Types That are being used in All Electric Vehicles ,for Example which Brand Make is used in CHETAK Bajaj & what type & How many hours it takes to charge ,A detailed video on Battery packs in All EV 🙏🙏👍👍
Good information. It's a treat Atul. Thanks to Dr. too. Short and to the point instead of more technical details. He seems to be very quality conscious.
If we made battery cells in India too then it would become 100% made in India, unfortunately Indian politicians and buisness faternity did not secure the lithium supply for India and Chinese Government and conglomerate good future planing made it possible for them to control 80% of the world's raw material refining, 77% of the world's cell capacity.
BMS must protect cells at any given point of time... Even at 100% discharge.... That is what We call SMART BMS........gor more details contact Mr. Nitin Banait
Do a real life range comparison test on highways, between nexon ev max and the MG ev , 41 kwh . With normal driving speeds of 80 to 100 kmph and AC on.
LFP batteries can be charged safely upto full 100 percent, this won't effect battery longevity unlike NMC battery. Only thing is that it shouldn't be discharged to zero level.
@@pratikbankar1761 At present BYD's E6 Electric MPV is coming with their unique LFP blade battery in India. Also Tesla's standard models are coming with LFP battery. The LFP battery energy density significantly increased and that could hit in the market by next year. Also most of the major EV manufacturers are shifting from Lithium Ternary battery (NMC) to LFP battery.
OLA uses lithium nickle aluminium chemistry I think, they are not lithium iron phosphate so yes you should never overcharge or undercharge them. Also they may have not put a limit on overcharging to get more range out of the battery. Use it between 20% to 80% for long use. TESLA has a inbuilt app system in which you can set the maximum charge % for the battery, like if we set to 90% then battery will only charge to 90% and that helps in getting more life out of the battery but OLA has no such feature and there is no way to automatically limit the charge to 80%, you will have to look at it constantly so it does not overcharge.

I have doubt ola has NMC 21700 something and let's say lfp has same series aka dimensions there would not be any difference in specific energy aka density so only advantage in that case will be charge cycle, C-rate and thermal stability not weight or size of pack and neither mileage am I right ?
Chandrakanth I appreciate your efforts in bringing out the technology behind ev battery, since you are in the teaching line as you have only introduced, would you go to the institution in the same dress code as you are presenting , kindly follow Indian dress code,don't imitate some western dress code,remember you are in India,for your kind information I am also in the teaching line, I am governed by some moral ethics.
if the battery cells are in a vacuum, air evacuated plastic bag , how does the air flow for cooling occur ? Temperature transfer through conduction will not be good through plastic .
yes no cooling system in the pack, they packed it in plastic later so water does not get in, this is the problem when a Medical Doctor opens a battery factory.
Sir आप अच्छी विडियो बना रहे हैं लेकिन जब आप किसी को कुछ पूछते या बोलने के लिए कहते हैं और सामने वाला कुछ कह रहा होता है तो पहले उसे अपनी बात पूरी करने दें फिर आप अपनी बात कहें। बहुत सी जानकारियां आपके बीच में बोलने के कारण ठीक से समझ नही आया।
Ye China se import karke idhar joint mar rahe he. Aur subsidy mangenge. LFP Battery safe hoti he ye myth he Tata Nexon Ather 450x uses LFP still caught fire. Manual efforts ke wajah se Human error ke changes bahut jyada he. Automation is best solution for this issue. NMC chemistry use kar ke Ola chali across india and across the world in Hot summer still it haven't caught fire almost 40k were running. Tesla also used the same chemistry. Now they are moving to LFP

Ola already did manufactured cell in TN though a prototype but we are moving ahead slowly
NMC is required to stop at 80% .....LFP need not be stopped at 80%
Thank you for the great explanation.
Does DEXPRESS are selling battery to individuals through online? If yes, how we can get the rate list and delivery charges?
Warranty????
Nice info
How much it will costs
Sir ji is company ka battery package acha h jaldi ek scooter nikalna chahiye.
Prise kya ha wo to batya hi nahi
These cells come from Shenzhen, and there are 3 variety based on quality. Indian market import mostly low quality cells.
If it is made completely airtight then how air circulation is possible?
BMS must protect cells at any given point of time... Even at 100% discharge.... That is what We call SMART BMS........gor more details contact Mr. Nitin Banait
Good
It is commercial production,if yes pl say the cost for 80ah,48v.
Good explanation sir ,
Sir I want to puchase the products of EV spares what's available with you sir
Kya aadmi he ye khud hi bol rha he jiske pass video banane gye ho uski bat to suno

Which vehicles comes with lfp
@@pratikbankar1761 Nothing because of their low energy density/kg

Does battery 80% charging rule applicable for OLA S1 pro?
Cells would not equally charge
Dod depth of discharge must 75percent
Discharge till 25 charge till 100
OLA uses lithium nickle aluminium chemistry I think, they are not lithium iron phosphate so yes you should never overcharge or undercharge them. Also they may have not put a limit on overcharging to get more range out of the battery.

Chandrakanth I appreciate your efforts in bringing out the technology behind ev battery, since you are in the teaching line as you have only introduced, would you go to the institution in the same dress code as you are presenting , kindly follow Indian dress code,don't imitate some western dress code,remember you are in India,for your kind information I am also in the teaching line, I am governed by some moral ethics.
if the battery cells are in a vacuum, air evacuated plastic bag , how does the air flow for cooling occur ? Temperature transfer through conduction will not be good through plastic .
I was thinking the same about why they are wrapping the battery pack in plastic!
yes no cooling system in the pack, they packed it in plastic later so water does not get in, this is the problem when a Medical Doctor opens a battery factory.
True
Why Lifepo4 battery lifecycle is more than other battery
if you vacuum pack it there wont be air circulation and battery will overheat.
Aren't they use prismatic cell for their battery?
Prismatics aren't that good, rather than grid energy storage, if one of the cell dies the whole pack dies, its not a problem in cylindrical cells
sir could you give me battery pack data
