Description / Abstract:
ISO 15118 specifies the communication between Electric Vehicles
(EV), including Battery Electric Vehicles and Plug-In Hybrid
Electric Vehicles, and the Electric Vehicle Supply Equipment
(EVSE). As the communication parts of this generic equipment are
the Electric Vehicle Communication Controller (EVCC) and the Supply
Equipment Communication Controller (SECC), ISO 15118 describes the
communication between these components. Although ISO 15118 is
oriented to the charging of electric road vehicles, it is open for
other vehicles as well.
This part of ISO 15118 specifies terms and definitions, general
requirements and use cases as the basis for the other parts of ISO
15118. It provides a general overview and a common understanding of
aspects influencing the charge process, payment and load
levelling.
ISO 15118 does not specify the vehicle internal communication
between battery and charging equipment and the communication of the
SECC to other actors and equipment (beside some dedicated message
elements related to the charging). All connections beyond the SECC,
and the method of message exchanging are considered to be out of
the scope as specific use cases.
NOTE 1 Electric road vehicles specifically are vehicles in
categories M (used for carriage of passengers) and N (used for
carriage of goods) (compare ECE/TR ANS/WP.29/78 ev.2). This does
not prevent vehicles in other categories from adopting ISO 15118 as
well.
NOTE 2 This part of ISO 15118 is destined to orientate the
message set of ISO 15118‑2. The absence of any particular use case
in this part of ISO 15118 does not imply that it shall not put into
practice, with the required messages.
NOTE 3 This part of ISO 15118 and ISO 15118‑2 are designed to
work independent of data transfer medium used. However, this series
of documents are made for fitting the specified data link layers in
the corresponding documents in this series.
