EVSE stands for Electrical Vehicle Supply Equipment and refers to any device intended to provide electricity to charge designated vehicles.
In European countries, they got unique continental identifiers which ease data exchange and rich value services. They are delivered by national codification offices and those references are often available in official datasets. Add them in OSM brings ability to link with those external datasets.
eMi³ standard (particularly v1.0 part 2 §1.3) defines which format this identifiers should follow (surely related to 2014/94/EU directive).
This page has been completed upon free information gathered online without any support of a particular operator. We don't pretend to reproduce the internal information model of a particular operator but only to propose a consistent and reliable documentation as to enable a independent and responsible contribution to OSM.
Format
The whole standard doesn't apply on OSM. We only use identifiers for stations and equipment which are the only physical features we can map.
Separators
eMI3 standard v1.0 part 2 § 1.3.2 (don't confuse with §1.2.2.1 and different eMA identifiers) uses the * separator in identifiers syntax as to ease human reading and encourage to don't use it in digital or automated exchanges.
Nevertheless, many files available online still contains the separator, so does OSM to conform to what is read and verifiable on ground.
This point has to be took with caution.
Charging pools
Charging pools are facilities where you find several charging stations and they got an identifier which have the following scheme:
- Country code
- National operator code
- P for Pool, it's a charging place/facility
- National pool code, unique in the country mentioned by the country code
Example : FR*M13*P13029*001 * FR: Country code, here France * M131: National operator code * P: Pool prefix stating it's a charging pool * 13029-001: National unique pool code
Charging stations
eMI3 standard v1.0 part 2 §1.3.1 states that station level doesn't require a global identifier.
As osm's amenity=charging_station refers to this level, it will usually get the pool's identifier in ref:EU:EVSE=*.
Using the equipment level is only valid when the station only contains one charging device. Many have 2 or 3 equipment inside.
Stations may have local identifiers in a given pool. It can be described in OSM with ref=*.
Charging devices
Inside a given place, you'll find charging equipment. They got identifiers which have the following scheme as well:
- Country code
- National operator code
- E for EVSE, it's a charging device
- National equipment code, unique in the country mentioned by the country code
Example : FR*M13*E13055*001*2 * FR: Country code, here France * M131: National operator code * E: EVSE prefix stating it's a charging device * 13055*001*20: National unique device code
Charging sockets/connectors
eMI3 standard v1.0 part 2 §1.3.1 states that connector level doesn't require a global identifier.
