Ratio Analysis of Fast Charger in the Design of an EV Charging Station using MCMC Sampling

Abstract

This study addresses the urgent challenge of expanding the electric vehicle (EV) charging infrastructure to meet the growing demand as EV adoption grows. The cost difference between fast and slow chargers is as much as sevenfold, and EV aggregators require assistance designing more cost-effective charging stations. The proposed method provides a method for determining the ratio of fast chargers in an EV charging station based on simulation analysis. The EV charging demand model is generated by MCMC sampling using Markov Chain characteristics, and a probability distribution based on actual data is applied. Ratio analysis of multiple charger combinations presents an insightful design for the EV aggregator.
