Batteries Figure 5. BMS measurement tabs. Conclusion
1. System tab: This is the main landing page of the application (Figure 4). It allows the user to establish the serial PC communication, select the number of connected AFE boards, and determine the measurement interval and thresholds to be used for overvoltage and undervoltage checks. After hitting connect, the user is ready to start measurements. If both
System Status lights turn green (as in Figure 4), the measurement tabs appear depending on the number of boards entered by the user. 2. BMS tab/s, as illustrated in Figure 5, display the measurements processed by the ESCU to each connected AFE. The BMS tab/s contain the cell and GPIO voltages, status, and fault readings by the AFE board. The cell
voltage measurement is also graphically represented and plotted in real time. 3. Reference tab: The GUI includes a reference tab representing a high level block diagram of the board and schematics. The schematics and Gerber fi les along with the evaluation fi rmware, GUI, and user guide are open-source and provided by ADI.
In the fast-evolving energy market, there is a pressing need for BESS. The demand is urgent for a complete solution that is ready to be deployed. Support is also needed to speed up the time to market and not add unknown delays. ADI is prepared to meet that demand in full with its ESCU. This board provides the key features required for BESS and provides a complete foundation with flexibility for further development. With the BMS controller solution from ADI, users will be able to: Evaluate multiple AFEs simultaneously since this solution targets stackable and scalable architectures. No additional isoSPI transceiver board is required. Debug the BMS system seamlessly due to the on-board JTAG, status LEDs, and various connectors and interfaces. Decrease time to market by leveraging open-source hardware and software. ADI’s BMS controller board is equipped with the key features required for BESS and offers a flexible foundation that’s necessary for future development.
