| Question | Outcome |
|---|---|
| What are we using for the AFE? | LTC6811 - 12-cell AFE, add LTC1380 I2C muxes to support up to 32 temp sensors |
| Daisy chained or addressable? | Addressable - we'd like to put LTC3300 balancers on the same isoSPI line |
| What architecture are we using? | Single controller board, carrier board reads current and uses LTC6820 isoSPI interface, AFE boards contain AFE, balancers, and thermistor inputs Master battery box contains controller board, slave battery box is connected by isoSPI |
| Active vs. passive balancingActive | Passive balancing - passive just burns power and we need higher currents to be effective- See follow-up discussion in BMS Architecture Discussion for details |
| How many cells should we balance across? |
