EV charging roaming helps make this possible by allowing drivers to access charging networks beyond their usual provider, subject to the agreements and systems in place.
It is similar in concept to mobile phone roaming: access is extended beyond the original provider through arrangements between different networks.
How does EV charging roaming work?
Roaming typically involves several parties:
- The driver uses a charging app, card or account.
- The mobility service provider (eMSP) provides the driver-facing service.
- The charge point operator (CPO) operates the charging station.
- A roaming platform or hub helps exchange information between participating parties.
When a driver starts a charging session, the systems communicate to check access and exchange relevant session information. Billing and settlement depend on the commercial agreements between the parties.
Why is roaming important?
Roaming can help:
- Give drivers access to more charging locations.
- Reduce the need for separate accounts across networks.
- Improve the convenience of longer journeys.
- Help operators make their chargers accessible to a wider customer base.
The experience depends on network coverage, pricing arrangements, interoperability and the roaming agreements in place.
What do CPOs need to manage roaming?
Operators need charging infrastructure and management systems that can support the required communication, access and transaction workflows.
They also need reliable session information and processes for managing users, tariffs and reporting.
Electric Miles’ emPACT CPMS provides centralised charging operations for CPOs and commercial charging teams, including charger, session, driver, access and tariff management.
Roaming integrations and commercial arrangements should be checked against the specific platforms and partners involved.

Frequently asked questions
Can drivers use one app across different EV charging networks?
Yes, where the app or mobility service provider has roaming agreements with the relevant networks.
Is EV charging roaming free?
Not necessarily. Prices depend on the charging provider, roaming partner and applicable tariff.
Does roaming mean all charging networks are connected?
No. Access depends on agreements, technical integrations and participating networks.
