Deploy Plug & Charge without the complexity
Voltier handles certificates, contracts, billing, and ecosystem integrations — so your engineering team can launch ISO 15118 Plug & Charge in days.
What is Plug & Charge?
Plug & Charge (ISO 15118) lets EV drivers plug their vehicle into a charging station and start charging instantly — no apps, no RFID cards, no payment terminals. Authentication and payment happen automatically through digital certificates exchanged between the vehicle and the charger.
No apps
No RFID cards
No payment terminals
For drivers, it's the simplest possible charging experience. For charging networks, deploying it has been anything but simple. That's where Voltier comes in.

Why Plug & Charge is hard to implement
ISO 15118 is a sprawling standard
Plug & Charge requires a full PKI hierarchy — root CAs, sub-CAs, provisioning certificates, contract certificates — plus vehicle identity management and strict compliance with ISO 15118-2 and -20. Most teams underestimate the engineering effort by 3–5x.
Every ecosystem has its own integration
Hubject, Gireve, and Irdeto each have different APIs, contract models, and onboarding processes. Connecting to all of them means maintaining three separate integrations — and keeping them all in sync.
Contract provisioning is operationally heavy
Matching drivers to vehicles to contracts in real time, handling updates, revocations, and edge cases — all while maintaining audit trails — requires purpose-built infrastructure most teams don't have.
It never stops requiring engineering time
Even after launch, certificate renewals, ecosystem updates, compliance changes, and billing reconciliation demand ongoing engineering resources. Most teams discover this too late.
Voltier replaces all of this with one platform.
One API integration gives you certificates, contracts, billing, and ecosystem connections. Your team writes code against our platform; we handle the infrastructure underneath.

Certificate Management
Full ISO 15118 certificate automation. Voltier manages the entire PKI chain: root CA integration, sub-CA provisioning, contract certificate issuance, renewal scheduling, and revocation.

Launch Plug & Charge in 4 steps
Integrate our API
Connect your charging platform to Voltier with a single REST API integration. Full SDK support for Python, Node.js, and Go.
Configure contracts & certificates
Set your provisioning rules through the dashboard or API. Voltier handles the certificate hierarchy and contract matching automatically.
Test and go live
Use our sandbox environment to validate your integration, then flip to production.
Drivers just plug in
No apps, no cards, no friction. Voltier handles authentication, contract matching, and payment automatically.
Why choose Voltier for Plug & Charge?
One integration, not six
Replace separate integrations with Hubject, Gireve, Irdeto, certificate authorities, billing providers, and contract databases with a single Voltier API call.
Weeks to launch, not quarters
Teams using Voltier typically go from first API call to production in 2–4 weeks. Without Voltier, the same journey takes 6–12 months.
We maintain the integrations so you don't have to
Ecosystem APIs change. Certificate standards evolve. Voltier keeps all integrations current — your team never has to chase a breaking change.
