智能交通系统 - 通过运输协议专家组 第2代（TPEG2）的交通和旅行信息（TTI） - 第25部分:电动机充电基础设施（TPEG2-EMI）

[中文适用范围]： 本文件规定了'电动交通信息'(EMI) TPEG应用。EMI应用专门设计用于支持电动汽车(不仅仅是汽车)充电基础设施的信息，包括充电点的位置及其对相应车辆的适用性(例如连接器类型、充电模式)。由于电动汽车将比其他车辆占用'充电空间'更长时间，因此还考虑了可用性/等待时间和预订选项的信息，因为这些信息对于电动汽车用户优化路线/行程规划非常重要。通过TPEG技术标准化交付电动交通信息对TPEG服务的最终用户有以下好处：a)识别适合车辆的充电单元，从而避免不必要的旅行寻找合适的单元(还具有环境效益)；b)验证充电单元的实时可用性；c)提前规划并在充电公园预订位置的可能性，从而优化行程规划；d)选择充电公园中财务吸引力强的充电点的可能性，其中运营商与用户的电动交通提供商有计费协议。除了这些最终用户利益外，电动交通提供商和充电公园运营商也从标准化的TPEG格式中受益，因为它促进了电动交通信息与电动交通提供商和充电公园运营商管理系统之间信息交换使用的数据格式的协调，以及相关规范(例如Open Charge Alliance,[1] eMobility ICT Interoperability Innovation (eMI3),[2]等)。EMI应用作为交通信息等附加服务组件，旨在支持大量充电公园，仅需适度的带宽要求。 [外文原描述]： This document specifies the "electromobility information" (EMI) TPEG application. The EMI application has been specifically designed to support information about charging infrastructure for electric vehicles (not just cars), the location of e-charging points and their suitability for the respective vehicle (e.g. connector type, charging modality). As electric vehicles will occupy a “charging space” for longer a time than other vehicles, information on availability/waiting time and reservation options are accounted for, as they are highly relevant for enabling a user of an electric vehicle to optimally plan their route/trip. The standardized delivery, via TPEG technology, of electromobility information has the following benefits to an end user of this TPEG service: a) identification of suitable charging units for vehicles, thus preventing unnecessary travel to find a fitting unit (also has environmental benefits); b) verification of the real-time availability of charging units; c) possibility of planning ahead and reserving a spot in a charging park, thus optimizing trip planning; d) possibility of selecting a financially attractive charging point in a charging park where the operator has billing agreements with the user’s electromobility provider. In addition to these end-user benefits, electromobility providers and charging park operators also benefit from a standardized TPEG format as it facilitates harmonization of the electromobility information with the data formats used for the exchange of information between management systems of electromobility providers and charge park operators and related specifications (e.g. Open Charge Alliance, [ 1 ] eMobility ICT Interoperability Innovation (eMI 3 ), [ 2 ] etc.). The EMI application, as an add-on service component next to traffic information, for example, is laid out to support large numbers of charge parks with only modest bandwidth requirements.
