EV roaming lets drivers charge on charge point networks other than their home network. This article explains how roaming works and what it means for your operator account.

What is EV roaming?

EV roaming is an agreement between charging networks that allows their users to charge on each other's charge points. It works similarly to mobile phone roaming.

Two standards govern most roaming in Europe: OCPI (Open Charge Point Interface) and OICP (Open InterCharge Protocol).

Key roles

• CPO (Charge Point Operator) — owns and operates charge points. When a roaming driver uses your charge point, you are acting as a CPO.
• EMSP (e-Mobility Service Provider) — provides charging services to drivers. When your drivers use external charge points, Monta acts as an EMSP on your behalf.

How Monta handles roaming

Monta can act as both a CPO and an EMSP:

• Inbound roaming (CPO) — external drivers from other networks can access your charge points. You set the price and Monta handles the settlement.
• Outbound roaming (EMSP) — your Monta drivers can charge on external networks. Monta manages the session and billing.

Getting started with roaming

To enable roaming on your charge points, you need a Roaming operator ID and an active roaming agreement. See the related articles below.
