EV charging

OCPP back-office and payment connectivity for EV chargers in car parks, on streets and at workplaces. Chargers cannot take payment or report to the network operator without a reliable data link.

Technologies used: 4G LTESIM, eSIM and IP addressing

Typical set-ups

A bank of chargers in a car park

One router connects several chargers to the back office over Ethernet, often with a PoE or Ethernet switch. A multi-network SIM avoids depending on one network's coverage in the car park.

Typical kit: Teltonika RUT951 or RUT956, with a network switch and a multi-network data SIM.

Underground or multi-storey car parks

Signal is poor below ground. Put the router or antenna where the signal is and run Ethernet down to the chargers.

Typical kit: An outdoor Teltonika OTD140 at street level, or a router with an external antenna.

Things to check before you buy

  • Which chargers support Ethernet and which need their own SIM.
  • Signal in the car park, especially underground.
  • Remote management, as chargers are spread across many sites.

We also explain Teltonika's own EV chargers.

From Teltonika

Teltonika publishes case studies showing its routers in real projects. See: cellular routers for EV charging stations, outdoor router for an underground EV charging station. Teltonika's documentation wiki covers set-up for every router we sell.

Talk to an M2M and IoT connectivity specialist. Every site is different. Tell us what you need to connect, where it is and how you want to manage it, and our UK team will recommend the router, antenna and SIM, with configuration options if you want it ready to plug in.

Questions

Do EV chargers need a fixed IP?

Most OCPP chargers connect out to the back office, so a dynamic IP SIM is fine. A fixed IP is only needed if something must connect in to the charger directly.

Can I connect several chargers to one router?

Yes. Chargers with Ethernet can share one router through a switch, which is usually simpler and cheaper than a SIM in every charger.
