1. Battery Management System for 20 Serial cells Li-IOn battery. Each cell voltage range: 2.7V to 4.2V with typical 3.6V.
So entire system voltage range is : 54V-84V
2. The system has to be complete BMS, i.e:
SOC(state of charge), Overvoltage/cell protection, undervoltage/cell protection, Overcurrent protection in charging & discharging, short circuit protection in charge & discharging, over & under protection, cell balancing, communication like RS485
3. The best I could get is using combination of TI; bq76930 or this reference design : http://www.ti.com/tool/tida-01093.
This dont have gauging or cell balancing. Gauging can be added using external micrcontroller & programming.
Many other companies had solutions like intersil but its for balancing only.
I am looking some asic for this purpose though. Not one asic but may be combonation of some.
4. Had anyone experience in using some stackable system for this kind of application?
This is query from my client, I have to see if I can design it with some solution?
