Due to production costs we decided to go a step further and integrate the functions of the Battery-Management-System – Master (short BMS master) also onto the X-by-Wire board. When the boards are ready we are going to assemble the PCB in two ways.
If its assembled in the first configuration with only one CAN Module and SPI Drivers, its the board with X-by-Wire function. The second configuration is with two CAN Modules, a RS232 Interface and no SPI Drivers, then it has to be the BMS master Board, wich monitors during charging our 400V cell stack, the voltage of every cell.
