About The Project

The purpose of the project is to build from scratch a Battery Management System (BMS) by using a Model Based Design approach. Starting from the plant definition (customizable), we proceeded with the design of the control strategies both for the cell balancing as well as for the pre-charge, post-discharge resistors and contactors management. A complete simulation enviroment has been developed in order to test and appreciate all the functionalities.

Built With

• MATLAB
• Simulink

Documentation

The complete documentation of the project is reported in Final_Report.pdf file under:

battery-management\Docs\

Getting Started

To get a local copy up and running just follow these simple steps:

Prerequisites

Software:

• Matlab v2021a
• Simulink v10.3

Toolbox:

• optimization_toolbox
• power_system_blocks
• simscape
• simulink_control_design
• simulink_design_optim
• stateflow

N.B: In order to get the list of in-use toolbox in a project use the following command (after run) :

license('inuse')

Installation

1. Clone the repo

   git clone https://github.com/meltinglab/battery-management.git

2. Open the simulationUI.slx file under:

   battery-management\workspace\Simulation\MIL\

Usage

In order to test the whole system (plant+controller), just follow these steps:

1. Compile & Run by clicking on the "Play" button
2. Adjust the control parameters and evaluate the behavoiur at run-time

For more examples or a detailed description of all the blocks, please refer to the Documentation

Hardware Implementation

In order to be used in an embedded device, the controller code has been ported to an STM32F4-Discovery board.

The whole porting process has been carried out by using the Embedded Coder and, in particular, the support package for STMicroelectronics Discovery board.

Additional prerequisites:

Hardware:

• STM32F4-Discovery board

Any other compatible board with the embedded coder can be used but some additional work may be needed.

Toolbox:

• embedded_coder
• stm32_discovery_support_package

Setup

FW package folder:

1. Open the testF4.slx file under:

   battery-management\workspace\Simulation\SIL-PIL\

2. Double-click on the bms_f4 model
3. Click on the apps pane
4. Under Get Add-Ons click on Manage Add-Ons
5. Click on the the "Setup Gear" on the right of the "Embedded Coder support package for STMicroelectronics Discovery boards"
6. Follow the setup instructions and make sure to specify the right firmware package folder:

   battery-management\workspace\STM32F4-Discovery_FW_V1.1.0\

Discovery COM port

1. Assuming that you have already opened the testF4.slx file
2. Click on the Hardware pane
3. Click on Hardware settings, then open the hardware implementation pane
4. Under Target hardware resources > PIL make sure to select Serial (USART2) and then insert the right COM port of your USB-Serial converter

N.B. A detailed description on how to setup the communication interface for PIL execution can be found here

Usage

1. Open the testF4.slx file under:

   battery-management\workspace\Simulation\SIL-PIL\

2. By clicking on the "Play" button the system will Compile & Deploy two controller models: the first will run on the discovery board, the other directly on your PC.
