“…Therefore, smart charging-scheduling models and algorithms for managing residents' charging behaviors should be developed. In addition, techno-economic assessment modeling [54] can evaluate the financial viability of such community charging hubs shared by apartment complex residents to enhance home charging accessibility and economic viability.…”

Early battery electric vehicle (EV) adopters can access home chargers for reliable charging. As the EV market grows, residents of multi-unit dwellings may face barriers in owning EVs and charging them without garage or parking availability. To investigate the mechanisms that can bridge existing disparities in home charging and station deployment, we characterized the travel behavior of multi-unit dwelling residents and estimated their EV residential charging demand. This study classifies the travel patterns of multi-unit dwelling (MUD) residents by fusing trip diary data from the National Household Travel Survey and housing features from the American Housing Survey. A hierarchical agglomerative clustering method was used to cluster apartment complex residents’ travel profiles, considering attributes such as dwell time, daily vehicle miles traveled (VMT), income, and their residences’ US census division. We propose a charging decision model to determine the charging station placement demand in MUDs and the charging energy volume expected to be consumed, assuming that MUD drivers universally operate EVs in urban communities. Numerical experiments were conducted to gain insight into the charging demand of MUD residents in the US. We found that charging availability is indispensable for households that set out to meet 80% state of charge by the end of the day. When maintaining a 20% comfortable state of charge the entire day, the higher the VMT are, the greater the share of charging demand and the greater the energy use in MUD chargers. The upper-income group requires a greater share of MUD charging and greater daily kWh charged because of more VMT.

“…They suggest that such communal charging hubs can provide the flexibility of installing EV chargers near existing electric outlets. Zhang et al (2023) further investigate the performance of charging hubs to reduce wait times by introducing charging schedule management. Additionally, while some shared dwelling types (e.g., townhouses) may have the physical capacity for an electrical upgrade, the presence of a condominium homeowners association (HOA) may require owners to seek permission before making any alterations to their unit.…”

The shift toward electric vehicles (EVs) as a decarbonization strategy in transportation raises important energy justice concerns, particularly regarding fair access to charging infrastructure. This perspective synthesizes evidence on how access to, and experience of, charging infrastructure may differ across socio-economic groups across North America. We present a framework for assessing charging infrastructure equity that includes: (i) accessibility—proximity, reliability, visibility, affordability; and (ii) user experiences related to safety, payment ease, and co-located other services. The framework helps characterize the varied impacts across socio-demographic groups, including on low-income and marginalized communities. We explore how the direct and indirect effects of accessibility and user experience might influence the distribution and design of EV charging stations. Considerations of socio-economic diversity in the deployment of charging infrastructure are critical to ensure equitable benefits from electric mobility. We conclude that targeted actions from manufacturers, charging operators, and governments are needed to alleviate the disparities in access and experiences with public EV charging.
