Open standards and data exchange
for e-mobility
A brief overview of the protocols involved in the e-mobility chain and the importance
of open data platforms for an operator
Danilo Pederiva – Head of Digital Lab | Alperia SpA / AG

Open standards and data exchange for e-mobility | Open Data Hub Day 2021
Neogy was funded in 2019 as a joint venture between Alperia and Dolomiti energia. Among
the first companies to operate in the field.
Common objective: foster green e-mobility locally and at national level
The company was named among the «100 eccellenze italiane» in 2021 for its role in the
promotion of electro mobility in Italy
Neogy – a winning partnership

Neogy - the numbers
The company is nowadays the third italian operator in
the field of electro mobility.
600+ «smart» charging stations of which 60+ private
Hundreds of «non-smart» charging units sold
Neogy is among the founders of Motus-E, an italian
association devoted to the promotion of e-mobility.

Neogy - the numbers
Our region Trentino – Alto Adige shows very good numbers for both the availability of charging
infrastructure as well as for the sale of Evs.
We contribute to bring the region at the levels we commonly see in Northern Europe.

The e-mobility terms
What are the main elements in the e-mobility chain?
EV – Electric Vehicle
EVSE – Electric Vehicle Supply Equipment (charging
station)
CPO – Charge point Operator
EMP or MSP – E-Mobility Provider or Mobile Service
Provider
DSO – Distribution System Operator
Energy Supplier – Company selling energy

Roaming – The hubs
In the field of e-mobility, roaming is a fundamental enabler. CPOs and EMPs must be put in contact.
Customers wants to charge their car everywhere, and CPOs has every incentive to attract customers
towards its infrastructure
Neogy is a partner of Hubject (Berlin) – the biggest European CPO and EMP interoperator with 960+
companies connected (CPO or EMP) and 300k+ charging points in the network. Among Hubject’s
main stakeholders we find BMW Group, Daimler, Bosch, Volkswagen and Innogy.
Unlike the other roaming platforms, Hubject does not only offer a technical connection between parties
but also a contractual framework for roaming.

The protocols of e-mobility

Protocols: between EV and EVSE
IEC 61851 – The standard applies to EV supply equipment and focuses on the requirements for power
transfer and communication for control in DC charging.
ISO 15118 - This is a standard for the Plug & Charge feature that enables electric vehicles to
automatically identify and authorize charging transactions by simply connecting the EV to the charging
station. It is recognized as an important contributing factor to accelerate EV adoption, as plug & charge
greatly simplifies EV driver’s charging experience.
ISO 15118 also enables bi-directional EV charging, otherwise known as vehicle-to-grid (V2G). With
V2G, electric vehicles will be able to feed energy back to the grid when needed, thus helping reduce
costly system peaks and ensuring a more intelligent, reliable grid.

Protocols: between EVSE and CPO
OCPP is the shared language spoken between
open EV chargers and charging station
management systems used by the CPO.
It is an open-source communication protocol for
networked electric vehicle chargers. The vision of
OCPP is to make any EV charger work with any
charger management software, even if the charger
manufacturer and software developer have never
met and are building their products on the opposite
side of the world.
Commands may be initiated by the Charge Point
like e.g. authorize or start transaction as well as
from the Management system like e.g. remote
start/stop transaction

Roaming protocols
OCHP (Open Clearing House Protocol):
OCHP is managed and developed by Smartlab Innovationsgesellschaft GmbH and ElaadNL, which
are organizations founded by German and Dutch utilities respectively. OCHP is used by the roaming
hub e-clearing.net, a not-for-profit platform.
OICP (Open InterCharge Protocol OICP)
OICP was created by Hubject in 2013. – mostly around German OEMs. OICP can be used to
communicate within Hubject’s platform, enabling communication between MSPs and CPOs. According
to Hubject, it is the most widely implemented communication standard between European EMSP and
CPO systems.

Roaming protocols
eMIP (eMobility Inter-Operation Protocol)
The eMIP specification is designed and managed by GIREVE. The core business of GIREVE is to offer
a roaming platform for MSPs and CPOs. GIREVE was founded by EDF, Renault, CNR and Caisse des
Dépôts.
OCPI (Open Charge Point Interface)
The first OCPI protocol was originally developed by eViolin, a collaboration of several Dutch CPOs and
EMSPs. The OCPI protocol is managed and maintained by the EVRoaming Foundation, ensuring its
free availability.

Protocols: with a DSO
The basic function of the Open Smart Charging
Protocol (OSCP) is to communicate physical
net capacity from the DSO (or site owner) to
the back-office of the charge spot operator. The
protocol can be used to communicate a 24 hour
prediction of the local available capacity to the
Charge Spot Operator.
It is a protocol between charge point
management system and energy management
system of the site owner or the DSO system.
Therefore it is both applicable for site owners
and DSO’s.

Neogy has been collaborating with the Open Data Hub Team for years and
was among the first contributors in the field of e-mobility data
Throughout the last years the steps involved:
Defining a common schema for the information exchange – For the future:
implementation of a standard open protocol like OCPI may be beneficial
Participating in coordination meetings with Open Data Hub Team:
nowadays several e-mobility operators contribute with their data to the hub
Setting up the interface with the EVSE management system

Open Data Hub: the benefits
Making the status of the charging station even more available
to potential developers
Attract potential customers
Contribute to promoting our area / touristic destination
Perfectly aligned with Neogy’s goals: promote e-mobility
