Recently, electric vehicles (EVs) have been intensively utilized in various parts of the world. Because the use of EVs allows the prompted minimization of fossil fuel consumption, this modern mode of transport is regarded as environmentally friendly. Nevertheless, despite the benefits they afford, EVs cannot be extensively adopted worldwide because of the insufficiency of charging station infrastructures. Accordingly, there have been several attempts to establish EV charging stations supplied by a fossil fuel-powered main grid with electricity. However, these types of charging infrastructures can negatively impact the distribution system and environment; it can therefore result in peak load increment. A potential and efficient solution is the utilization of self-sustainable sources (such as photovoltaic (PV) energy), which can mitigate the adverse effects of fossil fuels. With this solution, the planning of the distribution system should be appropriate to satisfy the load demand because a large number of EVs will be connected to the grid. Because of the increasing importance of this subject, in this manuscript, PV-EV stand-alone connection and PV-EV-Grid in hybrid connection of charging system topologies and their associated control architectures are critically enumerated, presented, and discussed; several perspectives and problems that confront the EV charging technology are also highlighted. Furthermore, the impact of numerous EVs connected to the electricity grid is reviewed, and the analysis of various EV charging scheduling techniques and control topologies proposed in available literature is presented. Finally, research suggestions on the economic value assessment of grid operation and EV load, recommendations, and future research directions are underscored.

最近，电动汽车（EV）已在世界各地广泛使用。由于电动汽车的使用可以使化石燃料的消耗最小化，因此这种现代运输方式被认为是环保的。尽管如此，尽管电动汽车带来了好处，但由于充电站基础设施不足，电动汽车仍无法在全球范围内广泛采用。因此，已经进行了一些尝试来建立由化石燃料供电的主电网提供电力的EV充电站。但是，这些类型的计费基础架构可能会对配电系统和环境产生负面影响；因此可能导致峰值负载增加。潜在而有效的解决方案是利用自给自足的能源（例如光伏（PV）能源），可以减轻化石燃料的不利影响。使用此解决方案，配电系统的规划应该适合满足负载需求，因为大量的EV将连接到电网。由于该主题的重要性日益提高，在本手稿中，将对充电系统拓扑及其关联的控制体系结构的混合连接中的PV-EV独立连接和PV-EV-Grid进行严格地列举，介绍和讨论；还重点介绍了电动汽车充电技术面临的几种观点和问题。此外，回顾了连接到电网的众多电动汽车的影响，并介绍了现有文献中提出的各种电动汽车充电调度技术和控制拓扑的分析。最后，
