摘要

考虑到各种用例(例如工作场所充电)的不同要求，评估电动汽车(EV)充电架构之间的差异是选择交流和直流充电解决方案的关键。本文提出了电动汽车充电架构的模型和仿真，包括电网、光伏(PV)和电池储能系统(BESS)，用于不同的充电场景，以研究交流和直流充电在11千瓦和22千瓦功率水平下的功率转换效率。电动汽车充电器用于不同的架构中，以模拟使用电网，PV和BESS的充电场景。仿真参数包含典型的办公室消耗配置文件和两个功率水平的多个充电点。仿真结果表明，直流充电在光伏和BESS两种情况下均优于直流充电，且光伏充电效率更高。不同充电架构的日损失被外推到每周和每年的损失，以阐明光伏直流充电的长期效益。

Future workplace EV charging architectures: DC and AC charging choices

The evaluation of differences between the electric vehicle (EV) charging architectures is a crucial point in choosing between AC and DC charging solutions, given the diverse requirements of various use cases (e.g. workplace charging). This research paper presents a model and simulation of EV charging architectures, including the grid, photovoltaic (PV), and battery energy storage system (BESS), for varied charging scenarios to investigate the power conversion efficiency of AC and DC charging at 11 kW and 22 kW power levels. The EV chargers are used in different architectures to simulate charging scenarios using grid, PV, and BESS. The simulation parameters incorporate a typical office consumption profile and multiple charging points for both power levels. The simulation results demonstrate that DC charging is superior in both PV and BESS scenarios, with PV charging being more efficient. The daily losses for different charging architectures were extrapolated to weekly and annual losses to elucidate the long-term benefits of PV DC charging.
