What is OCPP PROTOCOL?
Open standards-based protocols such as OCPP offer the flexibility to coordinate charging hardware with NMS and network management systems. Some of these rules, like others, focus on communications and security. This is important because not all providers of electric vehicles program their stations and networks on the same playing field.
OCPP 1.6 to 2.0
The OCPP protocol, widely used for communication between charging stations and electric cars, enables standardization of communication and facilitates the control of information exchange. The protocol includes improvements in its protection mechanisms and aspects like the use of digital signatures and the use of PKI systems for strengthening its communication to meet future cybersecurity challenges.
OCPP 2.0 presents a fundamental revision of the protocol to improve authentication and encryption of connections and to develop a new and more refined model for the configuration of charging stations and the life cycle of charging operations. This means that it is not possible to write code that works with OCP 2.0 or any other OCP version, but is possible for libraries that use the 1.x version of OCP.
OSCP (Open Smart Charging Protocol) is managed by Open Charge Alliance (OCA), a global consortium of electric mobility pioneers that promotes open standards for the charging infrastructure of electric vehicles, like the OCPP. Simply put, OCPI is an open charging point interface that enables the automated roaming of electric vehicles over multiple electric charging networks.
OCPI (Open Charge Point Interface) underpins affordability and accessibility of the charging infrastructure for electric vehicle owners by allowing drivers to charge across multiple networks. The Open Charge Point Protocol (OCP) operates at the application level (OSI layer) and enables the communication between charging stations for electric vehicles via a central management system, the so-called charging station network similar to mobile phones and mobile phones. Compliance with OCPP streamlines operations by enabling electric charging station providers to be hardware agnostics and use a wide range of networked charging stations.
Companies such as Triden and Charge Drive can also develop software solutions for this. EVSEs (chargers for electric vehicles, consisting of chargers and associated electrical infrastructure) communicate with CSMs to help electric vehicle drivers find charging facilities, reserve slots, and receive payment authorizations. CSM helps companies that operate charging stations set tariffs and fees, generate reports, and perform diagnostics, scheduling, and monitoring of charging stations.
It provides data types for OCPP messages for remote procedure calls and uses them for error messages for remote procedure calls. In OCPP 2.0 messages can be class names, operation names, operation names, and answers.
OCP was developed in 2009 and is now used by many major players in the electric vehicle market such as utilities, manufacturers, back-office software suppliers, and charging station operators (CPOs). If anyone is wondering what OCPP is and what OCA is, let us be clear. It is an open standard that can be used by all persons responsible without any license requirements.
We “ARKO” want to offer you the best solution for your EVSE needs and are therefore working on software updates to make our network and charging stations OCPP compliant. We are currently testing OCPPs with charging stations at selected beta locations and plan to use OCPH for your stations on our over-the-air updates. DNVS is an independent testing and verification service that helps you ensure high-quality interoperability between your OCP 1.6 charging stations and charging station management solutions.
While the market for electric vehicles is growing, charging station operators want to expand their infrastructure to meet future demand for electric vehicles. As the market evolves and hardware and software technologies advance, connectivity is critical. They work together for intelligent charging, battery exchange, and networking and require a communication protocol.
Electric vehicle drivers know that they have multiple charging and networking apps on their phones and carry multiple access cards. On the software side, there is no reason for EV drivers to have to carry multiple app cards. Many of the operating networks are used to operate hardware in their proprietary environments.
Drivers can be logged into multiple networks, station operators can buy smart chargers, most of which are level 2s and level 3s, or opt for a proprietary system such as the Open Charge Point Protocol (OCP).
If you look at the charging stations for electric vehicles, you will certainly find the term “Open Charge Point Protocol” (OCP) or “not connected” to describe such a system. Unlike EVo chargers and IEVSE, IVESE charging stations are true OCPP units that you can connect to a network of partners. Since OCPPs charging stations do not require the use of a specific network, they can be connected to all available providers in your area, such as your utility company.
Open networks allow owners of charging stations to use multiple open networks. In closed networks, proprietary protocols are used to communicate between stations and servers. Owners can, however, upgrade to different open standards-based networks and devices with the same hardware.
This is because many early adopters of electric vehicles are frustrated by the large number of apps that slow down the registration process, the number of errors that occur, and the fees. This is one of the opinions we share with AMP Control.
OCP allows you to authorize EV drivers at certain charging stations to obtain meter readings (such as WH charges) during the process, allowing the operator to update the charger’s firmware. Currently, most major loading station manufacturers use OCPP clients in the role of CPO (Operator Central System) with a full OPP implementation in accordance with OPP guidelines. Using a non-OCP software system can lead to expensive customizations and is not recommended.
