Development and application of mobile charging station complex under multi-scenario charging requirements

Summary: The paper focuses on the mathematical modelling and control system for UltraFast Charging Stations (UFCS) based on the DC micro-grid concept and Energy Storage System Integration to charge new Electrical Vehicles (EVs) at 800V DC within less than 10 minutes. The UFCS integrates a battery energy storage system (BESS) to reduce the peak power of AC main grid, with a dedicated control system to decouple the dynamics of the DC charging station from the AC grid by Load Levelling power management. Numerical simulation results in Matlab-Simulink software are presented to verify UFCS performance and the charging station's dynamics.

Summary: This study proposes a strategy for electric vehicle (EV) charging station planning, considering construction costs and driver satisfaction to determine optimal charging station locations. The method effectively meets charging demand while reducing construction costs, and solves the mixed-integer nonlinear problem using a genetic algorithm.
