Frequently Asked Questions
What is the difference between an EVSE, a location, and a connector?
The charging topology, as relevant to the eMSP, consists of three entities:
- EVSE - An EVSE controls the power supply to a single EV in a single session. An EVSE may provide multiple connectors, but only one of these connectors can be active at a time.
- Location - A location is a group of one or more EVSEs that belong together geographically or spatially.
- Connector - A connector is a specific socket or cable available for the EV.
What are the definitions of Public, Semi-Public (Restricted) and Private?
Public is assigned when the locations can be accessed 24/7 by everyone.
Semi-Public (Restricted) is assigned when the charging points are erected on private domain that are subject to specific, though non-discriminatory access restrictions, such as the usage of opening and closing hours as a requirement to use the associated facilities. For example, the recharging points in car parks of large warehouses or convenience stores, underground car parks, hotel and catering establishments, etc.
Private chargers are not accessible to the public, because they are placed on private locations like a private driveway. For example, some chargers are accessible only to the employees of a company or to the residents of a building.
What is the difference between EVSE_ID, EVSE_UID, and EVSE_OCPI_ID?
EVSE_ID: EVSE_ID ('charging_spot_id' in the CSV) is unique in the Data Retrieval Platform. Each EVSE has a unique EVSE_ID, and the EVSE_ID column is always filled in the Data Retrieval Platform.
EVSE_UID: EVSE_UID ('spot_connector_src_id' in the CSV) is unique in the CPO's system and is not unique in the Data Retrieval Platform. It is filled either by the CPO or Eco-Movement.
EVSE_OCPI_ID: EVSE_OCPI_ID ('charging_spot_ocpi_evse_id' in the CSV) is unique and compliant with "eMI3standard version V1.0", but it is not always filled in the Data Retrieval Platform.
How can I identify unique locations?
Every unique Location_unique_id ('master_location_external_reference' in the CSV) value is one unique location.
How can I identify unique EVSEs?
Every unique EVSE_ID ('charging_spot_id' in the CSV) is one unique EVSE. You can use it to count the number of EVSEs.
Do not use EVSE_UID ('spot_connector_src_id' in the CSV) or EVSE_OCPI_ID ('charging_spot_ocpi_evse_id' in the CSV) to count the number of EVSEs because EVSE_UID may not be unique and EVSE_OCPI_ID may not always be filled in the Data Retrieval Platform.
How can I identify unique connectors?
Every unique Connector_id ('spot_connector_id' in the CSV) value is one unique connector.
Who is a Charge Point Operator (CPO), owner, suboperator, and main operator?
Charge Point Operator (CPO) - The CPO is responsible for the charging station's management. In addition, the CPO is also responsible for the following:
- The administrative operation (for example, access, roaming, billing to MSP, etc.)
- The technical maintenance, which the manufacturer often performs.
The CPO can either own and operate a set of charge stations or operate them for third parties (suboperators).
Owner - The owner is the charge location's owner and often the charge point's owner. Depending on the location (public or private), the owner or the CPO purchases the energy.
Suboperator - The suboperator is a third-party brand under which the charging station operates.
Main Operator - The main operator is the primary operator of the charge location. If the charge location is operated by a suboperator, then the suboperator is the main operator. If the charge location is not operated by a suboperator, then the CPO is the main operator.
Why are special characters not displaying correctly in the downloaded report?
Special characters such as é, ç, ü, etc., may render incorrectly in applications, such as Microsoft Excel because Microsoft Excel cannot correctly display UTF-8 compliant CSV files containing non-English characters. To resolve this issue, follow the instructions here.
