GET TO KNOW THE BMS DEMO

Note: Numbers correspond to the steps to follow for setup.

STEP-BY-STEP INSTRUCTIONS FOR BMS DEMO SETUP

1. Connect BATT14CEMULATOR and RD33771CDSTEVB

Connect the battery cell emulator board (BATT-14CEMULATOR) and the cell controller board (RDCV33771C) using Cable_1.2.Connect RD33771CDSTEVB and MPC5775B-EVB for TPL link

Connect the cell controller board with the battery management board using the Cable_2 as shown in the figure to the right. This will establish the TPL link for communication.Either J1 or J2 can be connected to the RD33771CDSTEVB.User must connect positive (+) terminal of MPC5775B-EVB’s BMS interface connector  (J118 – pin 3,4 ) to BMS cell controller module positive (+) terminal and negative terminal to the negative terminal as shown in the next slide.

APPLICATION-SPECIFIC ITEM MPC5775B-EVB MPC5775E-EVB
Battery management connector J118 Not supported

PIN  DESCRIPTION  J118 REMARKS
1 FAULT_IN For TPL connection use pin 3 and4. Connect the positive to positive and negative to negative.
2 FAULT_RTN
3 TPL_P positive terminal
4 TPL_N negative terminal

3. Power up BATT14CEMULATOR&RD33771CDSTEVB

Connect the power supply to the BATT14CEMULATOR. Powering the emulator board also powers the RDCV33771C cell controller board.4. Connect the USB serial cable to MPC5775B-EVB and PC

Connect the micro-USB cable to the J116 micro-USB port for OpenSDA connection for programming and debug.Connect the USB side to the computer. Refer to MPC5775B-EVB QSG for more information.5. Power the MPC5775B-EVB

Connect 12V power supply to the power socket on the Development board.Make sure the status LEDs D14, D15, D16, and D32 for voltage levels 3.3V, 5V, 1.25V, and 12V supply respectively are glowing green on the board.6. Connect the CAN with the PCAN toolConnect CAN High and Low signals of J78 to PCAN tool CAN high and low.MPC5775B-EVB:J78 pin 2 is CAN0_HighJ78 pin 3 is CAN0_Low

PIN  DESCRIPTION REMARKS
1 5V TJA1145T PHY needs to be enabled via DSPI_B, Chip select CSB1. Use J58 & J60 for CAN module selection. By default connected to FlexCAN_A/MCAN0.
2 CAN1_0H
3 CAN1_0L
4 GND

7. Connect the CAN with the PCAN toolConnect the CAN_H and CAN_L signals of J78 of MPC5775B-EVB to PCAN USB CAN_H (pin 7) and CAN-L (pin 2) via two jumper cables.

Pin Configuration

1. +12V/+5V/Not Connected2. CAN-L3. CAN-GND/Not Connected4. Not Connected5. Not Connected 6. CAN-GND/Not Connected7. CAN-H8. Not Connected9. +12V/+5V/Not Connected

8. Import the MPC5775B_BMS_SDK_SW project to S32DSRun the S32DS for PowerPC 2.1 and follow the steps “a to f” to import the MPC5775B_BMS_ SDK_SW project.9. Generate Processor Expert Codes and Compile the binary image

Then build and run the program.Follow the steps “g” to “i” to generate the processor expert codes, compile and build the image. Refer to the MPC5775B-EEVB QSG to debug/flash the image.10. Connect the PCAN tool USB to the PCConnect the USB connector of the PCAN tool to the computer USB port.

11. Run the GUI softwareOpen the windows “Command Prompt” and execute the “Py Main.py” in the command shell.“Main.py” python file included in the GUI folder.Make sure you first install the Python 3.7 64-bit version and necessary packages PyQt5 and NumPy prior to the above step. Refer the readme file in the downloaded software GUI folder.

12. Setup the GUI link 

a. Select CAN1b. Set CAN baud rate to 500Kbpsc. Click “Start”, now the CAN link establish with the main controller boardd. Click “OK”e. Initiate global reset to BMS system by clicking “Global Reset”f. User able to observe the battery pack information shown in next slide

GUI INTERFACE 1/2

The figure below shows the GUI interface after communication has been established.

GUI INTERFACE 2/2

Adjust the battery levels via BATT-14CEMULATOR and observe the GUI for individual cell data in the “BCCDATA” tab.
