Hi,
I'm looking for an open source BMS (Battery Management System) which would allow me to develop my own electric vehicle lithium-ion battery pack for voltages range from 48V and up to 400V.
The problem I am encountering right now is the lack of any medium voltage open source BMS with advanced functions available on the market as far as I know. After looking on the internet for documentation and related projects, the closest thing (open source) I have been able to find, is this very cool open source 12 cells BMS :
- https://github.com/DieBieEngineering/DieBieMS
This BMS has several interesting features that I am looking for:
- STM32 MCU configurable through USB with the user interface developed for the VESC-project
- CAN Bus
- Integrated pre-charge and charge/discharge enable circuit.
Despite this, the rest of this BMS is limited to 12 cells /approx 48V and is using an outdated LTC6803 integrated chip.
Considering the voltage limitation of the DieBieMS, I am tempted to start the development of a similar BMS, based on it, but capable of handling a 400V/96S cells battery pack. For this, a Master and some daisy-chained slaves boards will be required instead of just one single board.

Open Source R&D isn't free! Any help is appreciated!

I am open to any suggestions that will help make this BMS great for this community!
