Running wireless networks in parking garages solely for #EV Charging payment is a massive pain. For above ground decks with strong cell signal we could equip each charger with a cell SIM card, but that gets annoying/costly as you go up in units. Who has alternative solutions? I know Xeal is one. Has anyone used a solution where one #evcharger has a cell modem and then acts as a “hotspot” to share that data connection?

TEQ was originally designed to do so. I will see to it that you receive the data sheet and install guide. Toward the end of our Beta program, we just started putting 5GLTE in everything! 80 to 90% of issues during Beta were comms related.

We do every site as you describe Chris Kaiser Single Cellular unit which connects up to 9 Wifi enabled units locally. Comms run through Cell enabled unit. Pretty standard now.

Chris Kaiser you can use a modem router with sim and use powerline WiFi extenders.
Hey Chris Kaiser, you've got some great offers here! Here's my 2 cents: most of these options need an internet connection, either through app or directly to access points, ethernet or router. The latter option still involves drilling for Ethernet wire passage to levels 2/3.4. It also depends on whether the installed chargers you've mentioned are for private or public use. For private use, an old-school method could work: check if the installed chargers support local RFID. Users would get RFID tags to activate their chargers, and smart meters installed on each wire run could track energy usage for billing. If it's for public use, though, one of the network solutions mentioned here will be necessary.

SWTCH has a solution similar to what you describe for above ground installations, would be happy to discuss if you want.

Buy one of those OCPP-men-in-the-middle-boxes and get a nice local load management for free ;) (almost free)

6 个月Chris Kaiser what about running an ethernet cable to each unit back to the distribution panel, then tie into a cradlepoint or similar modem with an antenna capable of reaching the outside world? Another possible solution would be same ethernet cables as above, but setup a hardwired network to the local cable or fiber provider at the distro panel. Happy to brainstorm other ideas with you as well.
