OCPP Compatible vs. OCPP Capable: What’s the Real Difference and Why It Matters
If you’ve been exploring EV charging solutions, chances are you’ve come across terms like OCPP-compatible and OCPP-capable more than once. And while they might sound interchangeable, the difference between the two can seriously impact your long-term EV infrastructure strategy, especially when it comes to future-proofing, flexibility, and maximizing ROI.
Let’s break it down in plain language.
What is OCPP?
Before we dive into the terms, let’s back up.
OCPP (Open Charge Point Protocol) is the global standard that allows EV chargers and charging management systems to talk to each other, even if they’re from different manufacturers. In short, it helps avoid vendor lock-in and ensures you’re not stuck with a closed, proprietary system.
Now, onto the terms that often get confused:
OCPP Compatible = Plug-and-Play Ready
When a charger is labeled OCPP compatible, it means the charger has already been tested, verified, and is ready to communicate using a specific version of the OCPP standard (e.g., OCPP 1.6 or OCPP 2.0.1). It's fully functional right out the box with most OCPP-compliant backend software platforms.
✅ Good to go
✅ Vendor interoperability
✅ Real-world testing has been done
✅ Meets current OCPP certification standards
Think of this like buying a smartphone that’s certified to work on any major carrier. You can pick the software that works best for your site and switch platforms later without replacing hardware.
OCPP Capable = Potential, But Not Yet Proven
Now here’s where it gets tricky. OCPP capable means the hardware could support OCPP… but it hasn’t necessarily been tested, certified, or fully integrated with any platform just yet.
It may still require:
Firmware updates
Custom configurations
Or even software development work to get it talking to a real-world backend system
🟡 Not plug-and-play
🟡 Can lead to unexpected costs or delays
🟡 Works... in theory but may not be field-tested
It’s kind of like buying a “smart” device that says it’s Alexa-ready, but then you realize you’ve got to do a bunch of steps and downloads to make it actually work.
Why the Difference Matters for Site Owners
Here’s the deal: if you’re investing in EV infrastructure, OCPP compatibility gives you flexibility. It keeps your options open as your needs grow, especially if you want to switch software providers, add more chargers, or apply for rebates and grants that require open standards.
On the other hand, OCPP capability might look cheaper upfront, but the extra costs in time, tech support, and upgrades can add up fast.
At Charli Charging, we prioritize OCPP-compatible hardware for every installation because we believe in building smart, scalable, and future-ready charging networks, without the guesswork.
How to Know What You’re Really Getting
If you're unsure, ask the vendor:
Is the charger OCPP compatible or just capable?
What version of OCPP is supported?
Has the charger been certified or field-tested with backend software?
Can I easily switch software platforms without replacing hardware?
If the answers aren’t clear, let us help you get clarity.
Final Word
OCPP compatible = Ready now
OCPP capable = Might be ready later
When it comes to commercial EV charging, the details matter. The right language on the spec sheet could mean the difference between a smooth rollout and a series of costly setbacks.
