What Is OCPP? A Practical Guide for EV Charging Businesses

Whether you're building a smart EV charging network or starting with a few basic chargers, you've probably come across the term OCPP—short for Open Charge Point Protocol.

But what exactly is it?

Do you actually need it?

And what if your project doesn't use any backend at all?

In this article, we'll break down OCPP in plain terms—without hype—and help you decide whether it fits your business needs.

What Is OCPP and Why Is It Important?

OCPP is an open-source communication protocol that allows EV chargers to connect with a backend system—also known as a Charging Station Management System (CSMS)—regardless of the brand or software vendor.

Think of it as the universal language that lets your chargers and your central management platform talk to each other.

With OCPP, you can:

• Use different brands of chargers and software together

• Monitor and control chargers remotely

• Avoid being locked into a single vendor

• Future-proof your charging network

OCPP is maintained by the Open Charge Alliance (OCA), and has become the de facto global standard for EV charging communication.

How Does OCPP Work?

Here's a simplified look at how OCPP functions in an EV charging session:

1. A vehicle is plugged into the charging station

2. The charger sends a start message to the backend system

3. The backend approves the session, monitors progress, and can stop/start remotely

4. Session data is recorded and used for reporting or billing

This communication happens in real time over the internet.

As long as both the charger and the platform support the same OCPP version, they can work together—no matter who made them.

OCPP Versions: 1.6 vs 2.0.1

Two main versions are widely used today:

Most EV infrastructure projects today still rely on OCPP 1.6J, as it's stable, widely supported, and feature-rich.

However, if you are planning for future upgrades, grid interaction, or advanced use cases like seamless Plug & Charge, OCPP 2.0.1 offers a powerful, more secure foundation.

·XTECK chargers support both OCPP 1.6J and 2.0.1, giving you the flexibility to choose what's best for your business.

What Is an OCPP Platform?

An OCPP platform (also called backend or CMS) is the software system that connects to your EV chargers.

It allows you to:

• Monitor real-time charger status and faults

• Start, stop, or reset chargers remotely

• Track energy usage and session data

• Generate reports and billing exports

• Control user access and pricing

• Enable load balancing and dynamic power management

Some operators use their own proprietary platforms, while others choose white-label or third-party OCPP platforms to manage their network.

·At XTECK, we support multiple backend integrations—yours, ours, or third-party.

Do You Actually Need OCPP for Your Project?

It depends on your project size, goals, and market.

Use OCPP if you:

·Need centralized control over multiple sites

·Plan to scale your network in the future

·Want to mix different brands of chargers

·Need to report usage, billing, or uptime

You may not need OCPP if you:

·Only have a few chargers in one location

·Don't need backend control or analytics

·Want the simplest, fastest deployment

·Are in a cost-sensitive market

For many emerging markets, non-OCPP chargers are still a practical, affordable solution—especially when paired with local RFID or app-based access.

·XTECK offers both OCPP-enabled and non-OCPP charger models to fit different project needs.

Final Thoughts: Build What's Right for Your Business

OCPP is a powerful tool—but not every project needs it.

If you're building a scalable charging network, OCPP gives you flexibility and control.

If you're focusing on speed, simplicity, and cost—there are other reliable ways to get started.

At XTECK, we support:

·Full OCPP-based smart charging solutions

·Plug-and-play, offline-capable chargers for simpler setups

·Hybrid projects that evolve over time

Frequently Asked Questions

What does OCPP stand for?

OCPP stands for Open Charge Point Protocol.

Can I use OCPP chargers without a platform?

No. OCPP is a communication protocol—it requires a backend to connect with.

Is OCPP mandatory for EV chargers?

Not at all. Many cost-sensitive projects use non-OCPP chargers successfully.

Which is better: OCPP 1.6 or 2.0.1?

OCPP 1.6 is widely used and reliable. OCPP 2.0.1 adds more advanced features for large-scale and future-facing projects.
