The oil consumption and CO2 generation were the drives to innovate electric vehicles. At the recent years, there is large evolution in the industry of electric vehicles and in the near future, the normal vehicles may be replaced with electric vehicles. The energy consumption of these vehicles depends on the vehicle body size and weight, passengers' weight, mobility speed, and vehicle communications. In this paper, we focus only on vehicle communications and propose a new concept called Electrical Vehicular Ad Hoc Network (E-VANET). E-VANET is a new trend of vehicular ad hoc networks (VANET) which composes of connecting a group of electric vehicles with each other and with the infrastructure to exchange information. In addition to the challenges of VANET such as mobility, routing, location awareness, etc., the main challenge in E-VANET is energy consumption that needs a great research effort to be reduced. Therefore, it is necessary to highlight E-VANET and new concepts, standards, and technologies that can be used to enhance its performance and reduce energy consumption. The main goal of this paper is to explain the concept of this new network type, its architectures, applications, and challenges as well as the technologies that can be merged with it to increase the network lifetime like software-defined network, fog computing, internet of vehicles (IoV) and cloud computing. This paper can open the door in front of the researchers to contribute in enhancing the work of E-VANET.

耗油量和二氧化碳的产生是推动电动汽车创新的动力。近年来，电动汽车行业发生了巨大的发展，并且在不久的将来，普通汽车可能会被电动汽车所取代。这些车辆的能量消耗取决于车身尺寸和重量，乘客的体重，移动速度和车辆通讯。在本文中，我们仅关注车辆通信，并提出了一个新概念，称为电动专用网络（E-VANET）。E-VANET是车载自组织网络（VANET）的新趋势，它由一组电动汽车相互连接，并与基础设施交换信息。除了VANET面临的挑战（例如移动性，路由，位置感知等）之外，E-VANET的主要挑战是能耗，需要减少大量的研究工作。因此，有必要重点介绍E-VANET和可用于增强其性能并降低能耗的新概念，标准和技术。本文的主要目的是解释这种新型网络的概念，其架构，应用和挑战以及可以与之合并以增加网络寿命的技术，例如软件定义网络，雾计算，互联网车辆（IoV）和云计算。本文可以为研究人员敞开大门，为增强E-VANET的工作做出贡献。以及可用于增强其性能并降低能耗的技术。本文的主要目的是解释这种新型网络的概念，其架构，应用和挑战以及可以与之合并以增加网络寿命的技术，例如软件定义网络，雾计算，互联网车辆（IoV）和云计算。本文可以为研究人员敞开大门，为增强E-VANET的工作做出贡献。以及可用于增强其性能并降低能耗的技术。本文的主要目的是解释这种新型网络的概念，其架构，应用和挑战以及可以与之合并以增加网络寿命的技术，例如软件定义网络，雾计算，互联网车辆（IoV）和云计算。本文可以为研究人员敞开大门，为增强E-VANET的工作做出贡献。车联网（IoV）和云计算。本文可以为研究人员敞开大门，为增强E-VANET的工作做出贡献。车联网（IoV）和云计算。本文可以为研究人员敞开大门，为增强E-VANET的工作做出贡献。
