Optimizing EV Charging Infrastructure in Multi-Unit Residential Buildings for Sustainable Energy Management

This study proposes an optimization approach to determine the optimal number of electric vehicle chargers in multi-unit residential buildings (MURBs), considering continuous and flexible charging options. Driver travel behavior is estimated using National Household Travel Survey (NHTS) data, followed by estimation of daily EV energy consumption. A mathematical optimization framework is then developed to determine the required number of chargers while maintaining satisfactory service. The results demonstrate that flexible charging can significantly reduce the number of required chargers while maintaining comparable service quality, contributing to more efficient infrastructure utilization and sustainable energy management.
