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.

BMS APPLICATION SPECIFIC CONNECTIONS

4. 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 tool
Connect CAN High and Low signals of J78 to PCAN tool CAN high and low.
MPC5775B-EVB:
J78 pin 2 is CAN0_High
J78 pin 3 is CAN0_Low

& 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 tool
Connect 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 Connected
2. CAN-L
3. CAN-GND/Not Connected
4. Not Connected
5. Not Connected| 6. CAN-GND/Not Connected
7. CAN-H
8. Not Connected
9. +12V/+5V/Not Connected
---|---

8. Import the MPC5775B_BMS_SDK_SW project to S32DS
Run the S32DS for PowerPC 2.1 and follow the steps “a to f” to import the MPC5775BBMS 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 PC
Connect the USB connector of the PCAN tool to the computer USB port.

11. Run the GUI software
Open 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 CAN1
b. Set CAN baud rate to 500Kbps
c. Click “Start”, now the CAN link establish with the main controller board
d. 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.
