📌 Video Highlights:
✔️ How the Constant Voltage (CV) charging method works for EV batteries
✔️ PI controller tuning for voltage regulation
✔️ Simulation of EV battery charging in MATLAB/Simulink
✔️ SOC variation and battery current response
✔️ Real-world relevance for EV chargers and battery management

💡 Why CV Charging?
Constant Voltage charging maintains a fixed charging voltage while the charging current decreases as the battery reaches full capacity. This ensures safe charging, prevents overvoltage damage, and improves battery lifespan.
