Since it has not been done yet and I’m sure there’s a bunch of people using the DieBieMS, I want to bring the thread from the old forum over here.
This is meant as an continuation of the old thread where we can discuss the usage, troubleshooting and sharing knowledge about the DieBieMS project.
Staring post from @JTAG the man behind it all:
Now that I am addicted to my electric skateboard with the nice performance of the VESC I feel that the only thing missing is a decent and competent BMS for a wide configuration of cells. Therefore I would like to start a long term project which I will document here, both to keep myself motivated + maybe implement some great ideas that arise in this topic. I think and hope that this forum is the right place for this new hobby project 
, feel free to point me to a problem you think I didn’t adres that is a bottleneck for the current available BMS’s.
Please note that my goal is not to make a cheap or affordable BMS, my goal is to make the most competent BMS for e-skateboard applications.
It will have the following features straight away: *Soft power switch input with LED on / off / charge indicator. *Charge input -> switched (high side) -> to charger input (to disable charger if a cell reaches the max voltage) *Discharge input -> switched (high side)-> to motor controller / VESC (to disable the load when a cell reaches the min voltage) *CAN bus interface for cell voltage monitoring and charger detection, status monitoring + more with future updates (like state of charge / state of health). *Charge current sensing (future capacity measurement) *Discharge current sensing (future capacity measurement) *Pre charge for high capacitive load (with short detection, in case the motor controller is shorted / dead / wrong polarity) *USB interface for serial communication and flashing (no need for a programmer -> HW serial bootloader is used)
Future features: *mAh / Wh counting + soc + soh calculation. *option to connect a cheap oled display for soc / soh display *firmware update over can (trough VESC maby?) *Chrome based configuration interface (+ firmware upgrades)
So far in my pre investigation I think I will be going with the following chipset: BQ76200 For high side N-FET switching + precharging LTC6803-4 Battery stack monitor CP2104 USB serial interface STM32F303K8 uC with HW floatingpoint LM5165 Power supply with 744043151 ISO1050 CAN Transceiver isolated BF1 Series fuse
