Hey Guys,
I'm new to the forum. I'm building a battery pack for my EV, i need a 48V 100Ah pack which can discharge at 3C. I plan on using NMC batteries for the same. I plan on making 5 packs of 48V 20 Ah each and then connecting them in parallel(yes, i know 13s NMCs will give me 46.8v but that's ok with my motor controller) . My questions are:-
1. I will be needing 1 bms per pack. That means I'll be needing 5 bms' in total. Am i right or i need to consider something more than this?
2. What do i need to consider while selecting a bms (as per my calculations i will need a 13s 60A(to handle 3c discharge) bms)?
3. Are bms' battery chemistry specific?
4. What do i need to consider while selecting the charger, in my case I'll be needing a 54.6v charger.
5. Can anyone suggest me a good, reliable BMS or a BMS vendor, one that's not very expensive, perhaps one which is tried and tested by any of yall?
Thanks.
