Concerning the display/master of my bms, I think for now not a lot of people will be interested by a complete "calculator" which manage all the car.
To begin something, I took the decision to build a board, very similar to the cycle analyst, that everyone must know !
It will be based on :
- TFT screen, probably 4.3", maybe 5"
- Speedometer input
- Current sensor input to sense the battery current
- Throttle over-ride output to be able to set a current and/or power limit, and why not, lower this limit when the pack become almost empty.
- Serial interface connected to the BMS slave boards
- SD card for datalogging and configuration
- Serial port for firmware upgrade, configuration, datalogging, and so on
- CAN bus, can be useful
- Pack fully charged output, to be able to cutoff charge if needed
- Pack fully discharged output, to be able to cutoff discharge if needed
What do you think about that ? An ev-analyser, similar to the cycle analyst for e-bike, but with big and beautiful screen, and integrated battery management ?
