Hello,
We have an application in which we have to monitor a serial protocol between a battery management control system and modules that transfers information of voltage,current,and the temperature of each cell in the battery pack .There's no information available about the protocol, this is propietary information of the manufacturer.the intention of the project is to replace the BMS with PlC,so I need to decode this serial protocol.
Finally I measure the baudrate which is 8928,and I used a piece code in Matlab so I collect the transfered data from modules to the controller.all of them are decimal numbers,or when I change int to char ,I can see some not readable data.,anybody have any suggestion how to find out some valuable information from these codes? I do not have any information about parity and stop bit but I also will try to find something by changing them randomely, and see the results.I just think that by chaging and discharging the battery and see the changes on these values maybe I can recogoniyed the relation between those values and the temperature,voltage an current.
thanks
