Democratizing access to charging infrastructure is a prerequisite for equitable electric vehicle (EV) adoption and use. Residential EV charging is the most prevalent and convenient option. However, multi-unit dwelling (MUD) residents have limited access to home charging, leading to higher operating costs and less flexibility. We introduce the concept of community charging hubs for shared charger use at MUDs. Our model minimizes the charging hub’s total waiting time. We measure the charging hub’s performance and evaluate the levelized cost of charging through a techno-economic assessment in Chicago, IL, New York City, NY, and Los Angeles, CA. We uncover trade-offs between the charging hub’s performance and its levelized cost of charging. Installing direct current fast charging stations costs more than adding level-2 stations but significantly reduces waiting times. The cost and performance metrics of small, medium, and large charging hubs and their average power profiles are presented for various hub configurations.

普及充电基础设施是公平采用和使用电动汽车 (EV) 的先决条件。住宅电动汽车充电是最普遍和方便的选择。然而，多单元住宅 (MUD) 居民获得家庭充电的机会有限，导致更高的运营成本和更低的灵活性。我们介绍了社区充电中心的概念，以便在 MUD 中使用共享充电器。我们的模型最大限度地减少了充电中心的总等待时间。我们通过在伊利诺伊州芝加哥、纽约州纽约市和加利福尼亚州洛杉矶进行的技术经济评估来衡量充电中心的性能并评估平准化充电成本。我们发现了充电中心的性能与其平均充电成本之间的权衡。安装直流快速充电站的成本高于增加二级充电站，但显着减少了等待时间。针对各种集线器配置，介绍了小型、中型和大型充电集线器的成本和性能指标及其平均功率曲线。
