- Digital Twin Model: Ensure your Simulink simulation model accurately represents the behavior of a lithium-ion battery, including voltage, current, and temperature dynamics.
- Data Exchange Between Simulink and Arduino: You need a way to exchange data between Simulink and the Arduino. This can be done through various communication protocols like Serial (UART), I2C, SPI, or even wireless communication like Bluetooth or Wi-Fi.
- Arduino Setup: Write an Arduino program to receive commands from your computer or another device and control the discharge current.
- Real-Time Data Transfer: You'll need a way to send data from Simulink to the Arduino in real-time. Simulink supports various data exchange methods, including using External Mode or custom MATLAB scripts. Use MATLAB Support Package for Arduino for seamless communication.
- Interpolation: To control the discharge current, you might need to interpolate the data sent from Simulink.
- Testing and Calibration: Calibrate your digital twin to match the real-world behavior of your lithium-ion battery. This might involve tweaking parameters in your simulation to match the response of the physical battery.
- Real-time Control Interface: Create a user-friendly interface for controlling the discharge current in real-time. This could be a software application or a physical control panel that sends commands to the Arduino.

Hi,
I am trying for digital twin for battery (lithium ion- 1 cell). I have finished simulation model using simulink, but I want to give discharge current from hardware (arduino) in real time. I have tried, but I can't find out the way. Let any one can help me to solve

Hey Nalla,
I understand that you want to create a digital twin for a lithium-ion battery and interface it with Arduino for real-time current control .
Here's a general roadmap on how you can approach this:
I hope this helps!
