Other Parts Discussed in Thread: BQ40Z50
We want to use the BQ40Z50 for our application with following parameters and functions.
1. 60Ah capacity battery pack - 96cells, 2.5Ah, 3.22V, 24 cells connected parallel and 4 such in series. -- Can we scale the pack current and Ah in the BQ40Z50 and also the shunt?
2. BMS should be able to estimate the SOC, SOH and have all the protections, it should be able to drive the charge and discharge FETs (30A continuous current) -- How many FETs can the BQ40Z50 can drive?
3. Battery charger is a dumb charger and no interface available. So cannot take the commands from the BMS. But charger is having the fixed CC limits and CV limits -- Can we use the BQ40Z50 in non communication mode and charge / discharge the battery?.
4. BMS should be able to interface with host laptop as and when connected via the SMBus. This is only to see the status of the battery (will be used very rarely).
