Why to Choose the Open Charge Point Protocol (OCPP)?

The Open Charge Point Protocol (OCPP) serves as a revolutionary means of communication between electric vehicle (EV) charging stations and central charging management systems.


The Open Charge Point Protocol (OCPP) serves as a revolutionary means of communication between electric vehicle (EV) charging stations and central charging management systems. Developed by the E-Laad Foundation in 2009 and now managed by the Open Charge Alliance, OCPP has become the industry-standard protocol for enabling seamless integration and interoperability among different EV charging infrastructure components. Today, with numerous hardware and software vendors worldwide supporting OCPP, its popularity continues to grow.

Why Opt for OCPP-Compliant Hardware?

For EV charging service providers aiming for reliability and uninterrupted service, the selection of OCPP-compliant hardware is crucial. Hardware downtime due to faults can significantly disrupt operations. By embracing OCPP, service providers can not only diversify their hardware sources but also manage multiple vendors remotely through a unified OCPP backoffice, ensuring seamless monitoring and control.

Key Features of OCPP for EV Charging Management:

To effectively manage EV charging networks, charging service providers require OCPP Backoffice Software. This software enables remote monitoring and management, allowing service providers to oversee charging stations, remotely initiate and end charging sessions, authorize drivers, access charging session metrics, and remotely configure hardware and update firmware. Additionally, advanced OCPP backoffice software can facilitate reservation management and provide options for configuring Smart Charging and Load Management across the charging network.

Support for OCPP in Hardware Suppliers:

Presently, most charging station hardware suppliers extend support for OCPP, making it an industry norm. However, it’s important to note that Tesla is a notable exception, as they utilize their own proprietary software stack. To find a comprehensive list of hardware suppliers that support OCPP, you can refer to the Open Charge Alliance members list.

Choosing Between OCPP 1.6 and OCPP 2.0.1:

While OCPP 1.6J is the prevalent version used by commercial charging service providers, OCPP 2.0.1 represents the latest iteration. Released in April 2020, OCPP 2.0.1 offers enhancements such as improved Device Management, Security upgrades, support for ISO 15118 (Plug & Charge), and Chargestations display screen compatibility. While the adoption of OCPP 2.0.1 by hardware vendors and EV Charging Management software providers is gradually increasing, service providers without specific 2.0.1 requirements are advised to continue with OCPP 1.6J, as it remains the reliable choice as of August 2022.

Building Custom OCPP Software Stack:

Building your own implementation of OCPP for EV charging hardware or charging management systems is indeed possible. You can download the OCPP protocol and start coding your unique implementation according to your specific needs and requirements.

OCPP’s Role in EV Charging Business:

It’s important to note that OCPP solely serves as the technical messaging protocol facilitating remote control of charging stations. To establish a paid EV charging service, additional elements such as payment handling, pricing setups, driver access control, and security measures are necessary. Moreover, building a remarkable driver app, customizing management dashboards, and producing insightful reports for customers also require independent efforts. Therefore, creating your own EV charging application entails developing not only an OCPP software stack but also the necessary business logic and customer-facing applications.
