Electric Vehicle Charging and Discharging Power Modeling

MATLAB simulation code serves as a powerful tool for studying electric vehicle charging and discharging power models. Through MATLAB implementations, we can develop various EV charging-discharging scenarios to analyze the complete power exchange process and explore optimization strategies for enhancing electric vehicle performance. The simulation code typically incorporates battery state-of-charge calculations, power flow management algorithms, and load profile simulations. Key functions may include battery characterization models using lookup tables or mathematical equations, charge controller implementations with PID control logic, and discharge scheduling algorithms considering grid constraints. Furthermore, MATLAB's Simulink environment allows for modeling different battery types (Li-ion, lead-acid, etc.) and vehicle configurations through parameterized blocks and subsystem components, enabling comprehensive analysis of their interrelationships. By leveraging MATLAB's optimization toolbox, users can implement cost functions and constraints to optimize charging schedules for minimizing electricity costs or maximizing battery lifespan. Thus, through systematic development and analysis of MATLAB simulation code, researchers can gain deeper insights into EV power management strategies and improve vehicle efficiency through model refinement and control algorithm optimization.
