ISO 21219-25:2024 インテリジェント交通システム — トランスポート プロトコル専門家グループ、第 2 世代 (TPEG2) による交通および旅行情報 (TTI) — Part 25:エレクトロモビリティ充電インフラストラクチャ (TPEG2-EMI) | ページ 6

3.1

electric vehicle

EV

vehicle that is (partly) electrically powered and operated

Note 1 to entry: With respect to the TPEG requirements, electric vehicles such as e-bikes are considered in addition to electric cars.

Note 2 to entry: Electric vehicle (EV) batteries can typically be charged at any regular power socket. If fast charging is required (e.g. during longer journeys), higher demands on the technical infrastructure are made. Specific sockets and high-power connector cables have been developed to allow a simple and secure usage of boost charging stations. It is necessary for the end user to know which options are supported by a charging station. EVs can have an “identity” for electronic readout, e.g. by means of a certificate. Other information which can be communicated by an EV to the infrastructure can also be relevant for the execution and planning of charging orders. The current battery charge condition, the power requirements during the charging procedure and the cruising range are parameters that can be relevant for the planning of charging orders. The vehicle and charging station can communicate via the connector cable, but other mechanisms are also possible, e.g. using the back-end system of the EV-manufacturer to which an EV is connected (via mobile data connection).

Note 3 to entry: Electromobility information (EMI) also covers the requirements for hybrid (partly electrically powered) vehicles.

3.2

charging park

grouping of multiple physical charging stations which technically and/or logically belong together and are being operated together

Note 1 to entry: A commercially operated car park or in a city district where publicly operated charging stations are grouped together.

Note 2 to entry: Charging parks are being operated by charging park operators.

3.3

charging station

physical unit (typically a column or cabinet-like structure) containing and managing one or more charging points offering the end user the possibility to authorize (typically by means of a card reader) and activate one of the charging points at the charging station, hook up the vehicle, and start the charging procedure

3.4

charging point

unit in a charging station at which an electric vehicle can be supplied with power

Note 1 to entry: A charging station may provide multiple charging points, which again may contain multiple sockets to support more than one charging connector type. In general, as soon as one socket at a charging point is in use, the charging point is occupied. Typically, a parking space is provided for each charging point at the charging station.

3.5

energy provider

business partner supplying energy to charging parks and their operators

Note 1 to entry: This includes all relevant energy suppliers, i.e. local solar power generators as well as traditional major companies in the power industry sector.

3.6

electromobility provider

EM provider

business partner for end users who charge their electric vehicles

Note 1 to entry: Typically, an end user has a contract with an electromobility provider (EM provider), the details of which are connected to an (RF) ID-card [having an (internationally) unique card number] that is used for authorization and billing. The EM provider ensures that their customers can charge their vehicles in as many charging parks as possible and bills the customer according to the respective contract.

3.7

charging park operator

entity which manages one or more charging parks

Note 1 to entry: The charging park operator maintains the charging site(s) and is a business partner to the energy provider and the electromobility provider (EM provider). Typically, a charging park operator bills the end user based on “roaming agreements” with multiple EM providers.

3.8

EVSE ID

electric vehicle supply equipment identity

globally unique identifier which identifies a specific charging point

Note 1 to entry: If a charging station has multiple charging points, multiple EVSE IDs are used. See also DIN SPEC 91286.^[16]

3.9

Reference-English “word”

word which enables information to be transmitted as a concept, thereby letting the receiver device choose the best possible representation of the given concept in the context of the other parts of the message

Note 1 to entry: This approach means that devices can present concepts in any language or even as graphical icons, for example. For further explanation, see ISO 21219-2.
