We visit the office of DEXPRESS, a manufacturer who have been selling electric cargo scooters to small businesses for more than 3 years. They also made their own battery packs.
In this video, Dr Chandrakanth shows how a safe Lithium Iron Phosphate (LFP) battery pack is made.

हम एक निर्माता DEXPRESS के कार्यालय का दौरा करते हैं, जो 3 वर्षों से अधिक समय से छोटे व्यवसायों को इलेक्ट्रिक कार्गो स्कूटर बेच रहा है। उन्होंने अपना बैटरी पैक भी बनाया।
इस वीडियो में, डॉ चंद्रकांत दिखाते हैं कि कैसे एक सुरक्षित लिथियम आयरन फॉस्फेट (एलएफपी) बैटरी पैक बनाया जाता है।

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.

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 ?

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.

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.

@polaris1985 2 жыл бұрын

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.

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!

@polaris1985 2 жыл бұрын

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.

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
