EV charging connectivity that stays up

A charger rarely works alone. It talks to a management platform for authorisation and monitoring, often handles or defers to a payment component, and needs a path for remote support and firmware updates. Each of those is a connectivity dependency, and the useful questions are about what happens when the connection drops: can the charger still deliver energy, does it queue transactions, and how does it recover when the link returns? Turning outage behaviour and update demand into procurement questions, answered by the charger and platform suppliers, avoids discovering the answers in the field.

Firmware is its own consideration. Updates can be large and are often scheduled in waves across an estate, so the connectivity has to carry occasional big transfers without starving the day-to-day telemetry.

Chargers are often at sites with no good fixed line, which is why cellular connectivity is common. A multi-network approach improves availability where any single network's coverage is patchy, and keeping charger traffic on a managed, isolated path keeps it separate from any other systems on the site.

Netavo provides multi-network IoT SIMs on its own mobile core and a private APN for IoT estates, which suits dispersed charging sites. Netavo provides the connectivity. Integration with the charging platform, including OCPP, the charger's offline behaviour and payment compliance sit with the charger and platform suppliers. SIMs are managed in Netavo's portal or through its API, so connectivity controls can sit alongside the platform's own.
