4 EV Charging Myths That Stop Parking Operators from Making Money

Quick Answer

Four persistent myths about EV charger interoperability are causing parking operators to delay investment and leave charging revenue unrealised: that hardware vendor lock-in is unavoidable, that roaming requires a third-party aggregator, that connecting multiple mobility service providers creates unmanageable complexity, and that pricing logic is fixed once a charger is installed. All four are false. OCPP decouples charger hardware from backend software so operators can switch platforms or mix brands without replacing physical infrastructure, while OCPI enables direct peer-to-peer connections with multiple MSPs under operator-controlled access rules and pricing terms. An API-first platform built on both standards gives parking operators real-time control over tariffs, loyalty pricing, user access, and data ownership without requiring hardware changes or vendor negotiations at each step.

This article covers each of these points in detail.

Offering EV charging services doesn’t have to be complicated.

If you’ve read our guide to EV charging for parking operators, you know that flexibility, scalability, and user experience are key to making charging work, and most importantly, they pay off.

Yet many parking operators hold back on adding chargers because of old assumptions about how it all works. Why?

Myths and outdated beliefs about EV charger interoperability are blocking progress. The result? Missed revenue, empty bays, and car-parks that could be energy hubs sitting idle.

Doesn’t sound ideal, now, does it?

In this article, we’ll bust the biggest myths around EV charger interoperability and show how you can take full control with the right platform, the right standards, and the right strategy.

Myth #1: "You need to stick to one charger vendor forever"

This myth is a top reason parking operators delay investment.

Nobody wants to get locked into a single hardware brand for the next decade. The good news? EV charging hardware doesn’t have to lock you in.

Thanks to the Open Charge Point Protocol (OCPP), you can mix and match hardware and software. OCPP guarantees your chargers speak the same language as your backend, no matter the brand.

That means you can:

• Start with the hardware that suits your site

• Change software platforms later

• Add new features without replacing chargers

Interoperability gives you options. And options give you power.

Myth #2: "Roaming always requires a third-party aggregator"

Roaming doesn’t have to mean losing visibility or control. The Open Charge Point Interface (OCPI) enables direct, peer-to-peer connections between your system and multiple mobility service providers (MSPs).

This means:

• You can allow access to drivers from several MSPs

• You can manage relationships directly or through partners

• You stay in control of data, pricing, and user experience

OCPI makes roaming flexible, transparent, and operator-led. Just like it should be.

Myth #3: "It’s too complex to allow access to multiple MSPs"

The idea that “more MSPs = more mess” is outdated.

With OCPI, onboarding multiple MSPs can be streamlined through APIs and automated configurations. You can control who accesses your chargers, how pricing is structured, and how usage is tracked , all from a single interface.

More MSPs means more drivers. More drivers mean more charging sessions. That’s what fills your bays and your revenue reports.

Myth #4: "Once installed, we can't change pricing or payment logic"

Not true. With the right backend platform, you can:

• Set different tariffs for different times of day

• Apply loyalty pricing for retail customers

• Offer free charging for selected user groups

• Adjust logic without touching the hardware

eMabler’s API-first approach gives you full control over pricing and payment experiences.

You adapt as your strategy evolves, without calling your installer every time.

The Role of Standards: OCPP + OCPI = Interoperable Future

True interoperability comes from using open standards.

• OCPP enables smart, remote management of your charging points.

• OCPI allows you to connect with MSPs and other CPOs directly.

Together, these standards let you scale your EV charging infrastructure while staying agile. You avoid vendor lock-in and gain the flexibility to choose the business model that works best for your site.

Is Your Charging Strategy Truly Interoperable?

A truly interoperable charging setup gives you freedom, not friction. Ask yourself:

• If you wanted to switch charger brands tomorrow, could you?

• Can you easily decide which MSPs get access to your chargers — and how they interact with your users?

• Are you able to adjust pricing or create loyalty offers without digging into contracts or calling your installer?

• Do you actually own your data and control the full user experience?

If any of that feels uncertain or out of reach, there’s a better way, and it starts with interoperability.

How eMabler Makes It Simple

At eMabler, we’ve built a platform that’s fully aligned with OCPP and OCPI, and we’ve wrapped it in a clean, API-first architecture.

With eMabler, parking operators can:

• Stay in control of pricing, branding, and user experience

• Enable access for multiple MSPs without technical chaos

• Guarantee compatibility with different hardware providers

• Make data-driven decisions with full transparency.

We don’t just tick boxes on a standards list. We make interoperability work in the real world, for real business results.

Let’s Switch the Lights On

Misconceptions about EV charger interoperability are stalling investments in infrastructure that could already be generating revenue. In this article, we’ve unpacked the most common myths , and shown how open standards like OCPP and OCPI empower parking operators to stay flexible, in control, and ready to grow.

Here’s a quick recap:

Your car-park can do more than hold vehicles. It can attract EV drivers, generate new income, and plug into a wider ecosystem of energy services, if it’s built on interoperable foundations.

eMabler helps parking operators get there. Our API-first platform connects OCPP chargers and OCPI roaming with the tools you need to manage pricing, user experience, access, and data; all while staying compatible with your hardware and partners.
