Plug & Charge Readiness Checklist for Operators
Sep 30, 2025
Read time: 5 minutes
EV adoption is moving faster than most infrastructure rollouts. More than 5 million electric vehicles are now on European roads, and that number is climbing steeply each year. Every one of those cars needs a charging session that works reliably, without apps, RFID cards, or complicated payment steps.
That is why Plug & Charge is becoming the industry standard. With ISO 15118 at its core, Plug & Charge makes charging secure, automatic, and simple for drivers. For operators, retailers, and mobility providers, Plug & Charge is both a driver convenience feature and a regulatory requirement, with AFIR deadlines in 2026 and 2027 making it mandatory for new public and private infrastructure.
The question is no longer whether to prepare, that one is a given. The focus now is on how quickly your business can be ready.
If you want to understand what Plug & Charge is and what it implies for your business, start with our guide to Plug & Charge. This article gives you a Plug & Charge readiness checklist designed to assess your infrastructure, identify gaps, and plan upgrades so you can stay compliant and grow with confidence.
1. Charger Hardware
Key Question: Do your chargers support ISO 15118?
Plug & Charge requires chargers that are compatible with ISO 15118. Many older chargers do not have this capability. Even if the hardware is technically compatible, firmware updates may be needed.
Checklist items:
Audit your current charger portfolio.
Identify which chargers are ISO 15118-ready.
Confirm firmware update availability with vendors.
Plan replacement or phased upgrades for incompatible units.
Why it matters: Without ISO 15118-capable chargers, Plug & Charge cannot function. Hardware readiness is the foundation of adoption.
2. Backend Systems
Key Question: Can your platform manage Plug & Charge sessions?
Authentication in Plug & Charge happens through digital certificates. Your backend must be able to handle certificate lifecycle management: issuing, validating, storing, and revoking certificates securely.
Checklist items:
Review backend architecture for ISO 15118 support.
Confirm integration with certificate authorities.
Test processes for certificate renewal and revocation.
Assess system scalability for growing session volumes.
Why it matters: Backend readiness connects chargers with mobility providers. Without it, authentication breaks down and sessions fail.
3. Security and Certificates
Key Question: Are your security processes ready for Plug & Charge?
Plug & Charge introduces new security requirements. Digital certificates must be handled with the same care as payment data.
Checklist items:
Define governance for certificate management.
Train teams on handling keys and credentials.
Establish monitoring for certificate misuse or expiration.
Align with industry standards on encryption and data handling.
Why it matters: Weak security undermines customer trust and exposes operators to compliance risks.
4. Mobility Provider Integration
Key Question: Can billing connect seamlessly through Plug & Charge?
For drivers, Plug & Charge is invisible. For operators, it requires coordination with mobility providers so billing flows from the charger to the driver’s contract.
Checklist items:
Confirm integrations with key eMobility providers.
Validate settlement flows for Plug & Charge sessions.
Align roaming agreements with Plug & Charge support.
Test billing accuracy in pilot environments.
Why it matters: A seamless experience for drivers depends on correct billing behind the scenes.
5. Roaming Agreements
Key Question: Do your roaming partnerships support Plug & Charge?
Roaming platforms such as Hubject and Gireve are already integrating Plug & Charge. Operators need to confirm that their roaming agreements and technical setups are ready.
Checklist items:
Review existing roaming agreements.
Verify Plug & Charge compatibility with platforms like Hubject and Gireve.
Confirm interoperability testing with roaming partners.
Plan customer communication for roaming and Plug & Charge together.
Why it matters: Customers expect both access and simplicity. Roaming provides access, and Plug & Charge delivers simplicity. Both must be in place.

6. Compliance with EU Deadlines
Key Question: Are you aligned with AFIR requirements?
The Alternative Fuels Infrastructure Regulation (AFIR) sets clear Plug & Charge deadlines:
From January 2026, all new public AC chargers must support ISO 15118-2.
From January 2027, ISO 15118-20 applies to all new or renovated public and private AC chargers.
Checklist items:
Map infrastructure rollout plans against AFIR deadlines.
Identify compliance gaps in current deployments.
Create a timeline for upgrades and replacements.
Engage compliance teams to track regulatory changes.
Why it matters: Plug & Charge compliance is mandatory, and delays risk penalties and reputational damage.
7. Customer Experience
Key Question: How will Plug & Charge improve customer journeys?
Plug & Charge is a technical upgrade that also shapes the driver experience directly.
Checklist items:
Define customer communication strategy for Plug & Charge launch.
Integrate charging into loyalty programs or retail offers.
Collect customer feedback during pilots.
Train staff to support drivers with Plug & Charge questions.
Why it matters: Adoption succeeds when customers notice the difference. Clear communication and visible benefits drive loyalty.
8. Operational Processes
Key Question: Are your teams ready to manage Plug & Charge?
Technology is only part of the story. People and processes must also adapt.
Checklist items:
Train customer support teams on Plug & Charge workflows.
Update maintenance procedures for ISO 15118 chargers.
Align finance teams on billing and settlement changes.
Document new operational playbooks for scale-up.
Why it matters: Smooth operations reduce costs and prevent service gaps.
9. Scalability and Growth
Key Question: Can your stack scale with adoption?
As more cars support Plug & Charge, session volumes will increase. Systems must scale without bottlenecks.
Checklist items:
Stress-test backend platforms for higher session volumes.
Validate performance at multi-site, multi-region levels.
Plan infrastructure upgrades based on demand forecasts.
Monitor KPIs to identify early signs of strain.
Why it matters: Scalability prepares networks for long-term growth without disruption.
Plug & Charge Readiness Checklist (Summary)
Hardware: Confirm that chargers are ISO 15118-capable and plan upgrades where needed.
Backend systems: Support certificate lifecycle management, including issuing, validating, and revoking.
Security: Put clear governance in place for handling digital credentials and monitor for risks.
