What is OCPP? Why Is It Important in Electric Vehicle Charging?

OCPP Nov 13, 2021

Hello People. This article discusses about What is OCPP and why Is It Important in Electric Vehicle Charging. Open charge point protocol (OCPP) is the electric vehicle industry standard open-source protocol for communication between charging stations and central back-end EV charging management systems.

Open Charge Alliance is a non-profit consortium created by leaders in the EV infrastructure industry. The Alliance defines one of the most widely used communication protocols which is the OCPP.

What is OCPP? Why Is It Important in Electric Vehicle Charging?

OCPP is open, royalty, and patent-free, and has become the communication standard for hundreds of charging networks across the globe. The Open Charge Alliance (OCA) oversees the continued development and enhancement of OCPP, ensuring it can keep up with the evolving market and encouraging compliance among hardware and software suppliers so eMobility industry players can better realize the potential of EV industry technologies.

Why Is OCPP Important?

OCPP compliance by suppliers ensures interoperability among eMobility ecosystem components optimizing communications among devices and operational management platforms. Compliance with OCPP is critical to EV charging business operations. Comprehensive connectivity improves network stability, utilization, and monetization while making it easier to cope with the complexities of daily activities.

What's the difference between OCPP 1.6 AND OCPP 2.0.1?

OCPP 1.6, adopted in 2015, includes open networking plus a handful of other features such as load balancing management support. Load balancing is a great feature as it allows site hosts to daisy-chain several charging stations to each other while using a single circuit. The charging stations intelligently share the circuit depending on how many EV drivers are plugged in. Load balancing is a great way to reduce installation costs as you only need a single circuit for 2-4 charging stations.

On the other hand, OCPP 2.0.1, adopted in 2020, includes everything in OCPP 1.6 plus a lot more.  There are new features added in OCPP 2.0 such as extended security, display for tariffs and costs, monitoring for operator and so on. New features such as improved transaction processing and added security further improve the charging experience.

Most significantly, a feature called plug and charge greatly improves the charging experience. With plug and charge, EV drivers simply plug in to begin charging. The access and billing is all handled between the charger and the car seamlessly. With plug and charge, there is no need for credit card swiping, RFID tapping, or smartphone app tapping.

Benefits or advantages of OCPP (Open Charge Point Protocol)

Following are the benefits:
Flexibility: Open standards based protocol such as OCPP offers flexibility and choice. It allows users to choose from many different hardware and software. It offers flexibility to match charging hardware with NMS (Network Management System).
Choice: OCPP compliant charging stations offer selection of charging network provider in users hands.
Interoperability: Open networks enable interoperability between equipments from different manufacturers. OCPP is de-facto network protocol throughout the Europe and it is used in 78 countries on every continent.
Scalability: It is easy to change equipments and to scale the system as per need. This allows owners to optimize cost and risk of one time investments.
Plug and Play: Owners can easily add new options and capabilities to existing chargers.
