ISO/TS 21219-25:2017定义了TPEG应用电动汽车充电基础设施（EMI）。它专门设计用于支持有关电动汽车（不仅仅是汽车）充电基础设施、电子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）的信息。由于电动车辆将在更长的时间段内占据“充电空间”，关于可用性/等待时间和预订选项的信息对于电动车辆的用户优化地规划他的路线/行程是高度相关的，因此也被考虑在内。 通过TPEG技术标准化地传递关于充电基础设施的信息对该TPEG服务的最终用户具有以下益处: a)为他的车辆识别合适的充电单元，从而防止不必要地开车四处寻找合适的单元(也具有环境效益)。b)验证充电单元的实时可用性。 c)能够提前计划并在充电公园中预订位置，从而优化他的旅行计划。 d)能够在充电园区中选择经济上有吸引力的充电点，该充电园区的运营商与用户的电动汽车提供商签订了计费协议。 除了这些最终用户的好处之外，电动汽车提供商和充电公园运营商也受益于标准化的TPEG格式，因为它允许电动汽车充电基础设施信息与用于电动汽车提供商和充电公园运营商的管理系统之间的信息交换的数据格式更容易地协调，并符合规范（例如，开放充电联盟【1】、电动汽车ICT互操作性创新（eMI3）【2】等）。). TPEG应用电动移动充电基础设施作为例如交通信息旁边的附加服务组件，被布置成仅支持适度带宽要求的大量充电园区。 [1]http://www.openchargealliance.org/ [2]http://emi3group.com/

ISO/TS 21219-25:2017 defines the TPEG application electromobility charging infrastructure (EMI). It 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 a longer period of time, information on availability/waiting time and reservation options are highly relevant for a user of an electric vehicle to optimally plan his route/trip and are therefore also accounted for. The standardized delivery, through a TPEG technology, of information on charging infrastructures has the following benefits to an end user of this TPEG service: a) Identifying suitable charging units for his vehicle, thus preventing unnecessary driving around to find a fitting unit (also has environmental benefits). b) Verifying the real-time availability of charging units. c) Being able to plan ahead and reserve a spot in a charging park and thus optimize the planning of his trip. d) Being able to select a financially attractive charging point in a charging park the operator of which has billing agreements with the user's electromobility provider. In addition to these end-user benefits, also electromobility providers and charging park operators benefit from a standardized TPEG format as it allows an easier harmonization of the electromobility charging infrastructure information with the data formats used for the exchange of information between management systems of electromobility providers and charge park operators and according specifications (e.g. Open Charge Alliance^[1], eMobility ICT Interoperability Innovation (eMI³)^[2], etc.). The TPEG application electromobility charging infrastructure, as add-on service component next to, for example traffic information, is laid out to support large numbers of charge parks with only modest bandwidth requirements. ^[1] http://www.openchargealliance.org/ ^[2] http://emi3group.com/
