摘要

本文提出了减少或防止配电网中电动汽车充电站短路损坏的各种解决方案。在evcs中,具有高电平电流的中压是标准化的。因此,防止短路故障的保护是一个严重的问题。短路程度的加剧可能导致电力电子设备的整体损坏。另一方面,电动汽车(EV)方面的电池也可能损坏。本文描述了电动汽车系统和电动汽车系统的结构细节,并描述了这些系统不同部位的故障位置。最后,对各种保护装置进行了综合比较。

Fault Current Protection in distribution system connected EVCH: A Review
This paper presents various solutions to reduce or prevent short circuit damages in distribution system connected Electric Vehicle Charging Stations (EVCS). In EVCSs, medium voltages with high-level currents are standardized. Hence, protection against short circuit faults is a serious concern. Intensification of short circuit levels may lead to the entire damage to the power electronic equipment. On the other hand, the battery can be damaged on the Electric Vehicles (EV) side as well. In this study, the structural details of EV systems and EVCSs are described, and the fault positions in different parts of these systems are described. Finally, a comprehensive comparison of the protection devices is given.
