Glossary

This Glossary provides the Abbreviations, Terms, Protocols in use in the EV industry at large and within GreenFlux.

Abbreviations

Abbreviation	Meaning	Explanation
CA	Charge Assist	The mobile B2C app made by GreenFlux. Both offered to consumers directly and as a white-label B2B add-on to the GreenFlux EV Portal
CCU	Charge Point Control Unit	A module (hardware) inside a charge station that controls the charge points and handles communications with the outside world and vehicles
CDR	Charge Details Record	A record of all necessary information required to bill a transaction that results from a charge session
CP Module	Communication Protocol Module	A module installed in a charge point which enables the charge spot to receive messages from the outside world
CPO	Charge Point Operator ( replaced by CSO )	The user who connects the charging cable to the charge point. CPOs build EV charging stations, install hardware from a variety of EVSE vendors, and ensure optimal ongoing EV charging operations. They provide the charging network infrastructure, managing the backend technologies as well the connection between the chargers, to deliver reliable and consistent EV charging. CPO customers are EMSPs, who manage the relationships with electric vehicle drivers.
CSMS	Charge Station Management System	This is an 'official' term used in the Open Charge Point Protocol terminology. OCPP is a communication protocol that is used between a charge station and a CSMS. A comparison would be a phone (the CSMS) that communicates via bluetooth (OCPP) with a car entertainment system (the Charge Station) (the analogy isn't perfect, but just to illustrate). A CSMS is basically the technical term describing the CPO platform.
CSO	Charge Service Operator	It is the party that operates a network of charge points and has contracts with CSPs to allow their customers to use the charging facilities
CSP	Charge Service Provider	The CSP is defined as the party that pays for the electricity with which the EV is charged
DSO	Distribution System Operator	The DSO manages the distribution network and has the interest of not overloading the (local) grid. In order to do this, the DSO sends out a (time-varying) capacity forecast, informing about the available capacity for charging EVs.
EMS	Energy Management System	There is no clear definition of an Energy Management System. You could argue that the GreenFlux platform is an energy management system given our smart charging technologies. Most of the time however, the term Energy Management System is used to indicate a local hardware solution that locally controls charge stations and/or battery systems, based on measurements taken locally
eMSP / EMSP	Electric Mobility Service Provider	Providers of charging stations and points
EV	Electric Vehicle
EVSE	Electric Vehicle Supply Equipment	EVSE is an acronym for Electric Vehicle Supply Equipment. It is the part that controls the power supply to a single EV in a single session

GSOP	GreenFlux Service and Operation Platform	GreenFlux backend

HPC	High Power Charging
ICCID	Integrated Circuit Card Identification Number	A unique 18-22 digit code that includes a SIM card’s country, home network, and identification number. You’ll usually find an ICCID printed on the back of a SIM card, but sometimes it’s included in the packaging materials instead.
LC	Local Controller	Component that communicates with the CP modules in the charge spot and is able to change the maximum charge current in the charge spot. The LC is controlled by the CSP (but can also operate in offline mode).
RFID	Radio-Frequency Identification	RFID-cards or RFID-tags or RFID-tokens refer to devices (quite often creditcard-like plastic cards) that are used by EV drivers to authenticate themselves at charge stations. As this is an internationally accepted and well-known term I think it's best not to translate it
SCC	Smart Charging Controller
SCiP	Smart Charging in Practice
TSO	Transport Service Operator	A TSO (e.g. Tenet ) ensures a reliable and uninterrupted supply of electricity in a high-voltage grid

Terms

Term	Explanation
Cable Capacity	The maximum capacity (in Amps) that can go through a cable before something goes wrong (e.g. burning fuse or damage to the cable itself)

Offline Mode	This is a working mode for a charge point in which it has no communication with the back office of the operator (usually due to communication failure)

Protocols

Protocol	Meaning	Explanation
eMIP	eMobility Interoperation Protocol	Created by GIREVE - Protocol to lay down foundations to open access to vehicle charging stations.
Hubject	Hubject	Hubject is a roaming hub, allowing CPOs and eMSPs to connect to each other through a single hub connection.
OCHP	Open Clearing House Protocol	Connects market actors in the field of electric mobility charging infrastructure
OCPI	Open Charge Point Interface	A platform to platform (partner) protocol. The Open Charge Point Interface Protocol is an independent open protocol that supports connections between Mobility Service Providers, Charge Point Operators, and Navigation Service Providers. OCPI aims to simplify, standardize and harmonize the EV market.
OCPP	Open Charge Point Protocol	The direction of this protocol is charger -> platform. It is an application protocol for communication between EV charging stations and a central management system, also known as a charging station network, similar to cell phones and cell phone networks.
OICP	Open InterCharge Protocol	A platform to Hubject protocol
OpeNADR	Open Automated Demand Response	A research and standards development effort for energy management led by North American research labs and companies. The typical use is to send information and signals to cause electrical power-using devices to be turned off during periods of high demand.
OSCP	Open Smart Charging Protocol	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 locally available capacity to the Charge Spot Operator. The Service Provider will fit the charging profiles of the electrical vehicles within the boundaries of the available capacity.
