Battery Management System (BMS) demo

Required Hardware

Part Number	Description
RDVCU5775EVM	MPC5775B BMS and VCU RDB with MC33664 TPL Interface Support
RD33771CDSTEVB	MC33771C-Based Battery Cell Controller Evaluation Board
BATT-14CEMULATOR	14 Cell Battery Emulator Board
PCAN-USB adapter	CAN Adapter

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

Connect BATT-14CEMULATOR and RD33771CDSTEVB

Connect the battery cell emulator board (BATT-14CEMULATOR) and the battery cell controller board (RD33771CDSTEVB) using Cable_1.

Connect RD33771CDSTEVB and RDVCU5775EVM for TPL link

Connect the battery management controller board (RDVCU5775EVM) with battery cell controller board (RD33771CDSTEVB) using Cable_2. This will establish the TPL link for communication.

Connector pin-out	Description
M24	TPL1 negative terminal
M25	TPL1 positive terminal

Note:Make sure that “+” of RDVCU5775EVM is connected to “+” of RD33771CDSTEVB.

Connect the CAN with PCAN tool

Connect the CAN_H and CAN_L signals of RDVCU5775EVM to PCAN USB CAN_H (pin 7) and CAN-L (pin 2) via two jumper cables.

Connector pin-out	Description
C12	CAN1_L
D12	CAN1_H

Connect the USB serial cable

Connect the RDVCU5775EVM board to PC via the USB serial cable.

Setup Tera Term Console

Open Tera Term on Windows® PC.

Select the serial port to which the micro USB of the development board is connected and click OK.

Go to Setup → Serial Port and select 115200 as the baud rate.

Power up RDVCU5775EVM

Connect 12 V power supply to RDVCU5775EVM. Make sure the status LEDs D14, D15, D16 and D32 for voltage levels 3.3 V, 5 V, 1.25 V and 12 V supply respectively are glowing yellow on the board.

Power up BATT-14CEMULATOR and RD33771CDSTEVB

Connect the power supply to the BATT-14CEMULATOR. RD33771CDSTEVB is powered at the same time.

Connect the P&E Multilink between PC and RDVCU5775EVM board

Preparation before importing the SDK project

Unzip the file Bootloader_Settings.zip that is located in [PROJECT_DIR] \PDC_5775B_SDK_Z7_0\Project_Settings to replace the folders.

Import the SDK project to S32DS

Note:Make sure to follow up the below IDE and SDK.

S32 Design Studio for Power Architecture@ 2017.R1.

S32 Design Studio for Power Architecture 2017.R1 Update 11 SDK PA RTM 3.0.0.

Generate processor expert codes

Note:After generating code, please modify the macro PIT_CLOCK_NAMES from “PITRTI0_CLK” to “PER_CLK” at MPC5775B_features.h is located in [PROJECT_DIR] \SDK\platform\devices\MPC5775B\include\

Debug your code

Select “Debug” and click the hammer icon to build the project.

Download to the MCU

Download the elf file to MCU.

Check the running status of the application

LEDs D45 and D46 on RDVCU5775EVM board should blink at different frequencies.

The board self-test message should be shown on the terminal.

Run the GUI software

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

Setup the GUI connection via PCAN USB

Select CAN Port and CAN baud rate to 500Kbps. Click “Start” to establish the connection with RDVCU5775EVM. Click “BMS Reset” to reset the BMS task in application. Input the related NTC parameters and click “OK”.
