A public repository for BMS algorithms for a NUCLEO BOARD.

Dependencies:   mbed

Hi Everyone!

Welcome to this repository from Howey's Research Group at the University of Oxford.

The code published here incorporates BMS algorithms for diagnosis functions such as SOC, SOH and Power estimation on a Kokam 53Ah Li-ion battery. This code was designed to work with a NUCLEO F401-RE board and to be tested with a dSPACE HIL Simulator. A short guide on how the set up works is available at https://bitbucket.org/ff95/bms .

The code is made up of three key parts. "Headers" and "Source" folders and the "main.cpp" file. As the code was generated by converting a Simulink model ( available on the BitBucket page), the headers and source code files generated by the conversion are in the corresponding "Headers" and "Source" folders. The "main.cpp" file sets up the ADC, the USB data transmission and starts the estimation (once a character "y" has been received by the computer it is connected to). It also transmits the data from the estimation via USB. Explanation on how to set up the communication with the board is available at BitBucket webpage, from where a MATLAB file can be downloaded which allows real time communication.

For any questions you can contact the author at federicomariaferrari@gmail.com .

The Simulink and Matlab files, together with a short guide, are all available at: https://bitbucket.org/ff95/bms.

Thanks for trying this out!

Federico
