Mass adoption of battery electric vehicles (BEVs) and their associated charging requirements introduce new electricity demand, which needs to be managed to minimise electricity grid upgrades. Management of BEV charging requires coordination and communication between various mobility and energy entities. Communication protocols provide a set of rules and guidelines to facilitate the communication and data exchange between two or more entities to ensure successful charging demand management and electricity grid integration of BEVs. A key challenge is that companies are currently developing and implementing several proprietary protocols to manage BEV charging, which could risk losing or vastly under-utilising BEV charging demand flexibility, and consequently hindering proper grid integration. This work presents the status quo on communication protocols and standards for vehicle grid integration and it is targeted for industries and governments. The objectives of the work are to review current protocols, present some of the advantages of open protocols, identify challenges and additional efforts required to develop, implement, and standardise these protocols to ensure that charging infrastructure for electric vehicles is synergistic with the operation of the electricity system.

注意车辆网格集成的开放式通信协议

电池电动汽车（BEV）的大量采用及其相关的充电要求引入了新的电力需求，需要对其进行管理以最大程度地减少电网升级。BEV充电的管理需要各种移动性和能源实体之间的协调和通信。通信协议提供了一组规则和指南，以促进两个或多个实体之间的通信和数据交换，以确保成功进行BEV的充电需求管理和电网集成。关键的挑战是，公司目前正在开发和实施几种专有协议来管理BEV充电，这可能会失去BEV充电需求灵活性或导致其利用率严重不足的风险，从而阻碍适当的电网集成。这项工作介绍了用于车辆网格集成的通信协议和标准的现状，并且针对行业和政府。这项工作的目标是审查当前协议，展示开放协议的一些优点，确定开发，实施和标准化这些协议所需的挑战和额外工作，以确保电动汽车的充电基础设施与电动汽车的运行具有协同作用。电力系统。
