What is OCPP?
The Open Charge Point Protocol (OCPP) is an open-source communication standard for EV charging stations and network software companies. Simply put, any EV charging station that is OCPP-certified can be configured to run any similarly OCPP-certified software.
Established in 2009 by the Open Charge Alliance, OCPP is designed to be a free, open-source, and easy to implement protocol that ensures all participants are speaking the same language. As a result, it has become the global benchmark for interoperability throughout the EV charging industry.
But why is important to have OCPP-certified EV charging equipment?
When you select an OCPP-certified hardware provider, you are open to certain freedoms that are unavailable to non-OCPP stations.
- Choose the EV software that is right for you. Every EV charging network is different. Pick the one that fits your needs
- Switch your EV software at any time and retain the ability to adjust your setup based on your needs at the time.
- Stimulate competition in the market by selecting an option that doesn’t lock you in to a single provider.
With OCPP-certified charging management software, you get access to features that non-OCPP software cannot provide.
- Make your stations visible to a wider audience by choosing a provider that operates on different hardware.
- Keep different EV charging hardware on the same network and manage all your stations from one place.
- Provide the best user experience by choosing industry-leading software designed for seamless EV charging.
OCPP is a free open standard for EV component vendors and network operators that enables interoperability between brands. It is essentially a freely available “language” used in the electric vehicle service equipment (EVSE) industry.
Yes. As the industry evolves, so do the protocols we use. Much like all software, OCPP goes through updates, allowing it to establish parameters for how interoperability plays into new charging station functionality (i.e., Vehicle-to-Grid communications). The most current version is OCPP 2.0, with OCPP 1.6J being its most recent predecessor.
Yes. Since both the hardware and the software are OCPP-compliant, they can be configured to work together. However, the process for integrating hardware with a new software needs to be done by the manufacturer to ensure everything is set up correctly.
If you are a charging station service provider that makes either hardware or software, you can apply to become a member of the OCA here. There are certain benchmarks your product must meet in order to be considered compliant, but we encourage everyone in the industry to join.
