Hi there
Today I went to charge my car and the charging won’t start. The fault light is flashing. Our mobile app reports “charger lost connection to the server”…
I turned off the unit power, waited a minute and reconnected it but the issue persists. On the Evnex charging unit, the network port is flashing blue.
Is this an issue just with our unit, or a wider outage? The app says our unit is an R72TS
I’ve also emailed support.
Hi Sol,
Thanks for getting in touch.
Our support team has opened a ticket and are investigating the issue.
At first instance it seems to be related to your unit in particular as opposed to a network outage.
We will get in touch with you directly to discuss the solutions/options.
Thanks for your patience.
Just following up in the public forum. Ok thank you for your email support, problem has resolved now that you reset it from your side.
Also thanks for the information RE the 3g shutdown, I wasn’t aware of that so will consider your offer of the discount on the upgraded 4G unit. Seems a shame to have to throw out the existing entire unit after only a few years of use?
Anyway are we able to easily swap over the old and new 4G unit (via local electrician) since the wiring is fairly new and assuming it meets the same standard? Or would we need you to sort out installation as well?
One other question, why do we need a charger with network access anyway? Is it only for the app? Could the unit charge with out network access?
In answer to your questions:
The E7 or X-series units are exactly the same mounting as your R-series charger so would be a very quick swap out. If you opt for an E2 it mounts slightly differently but would still likely be simple. You can arrange installation yourself, or we can arrange for you as required.
The network access enables the app, and provides us the ability to fault find and diagnose / fix problems remotely. It also allows you to receive updates as we add new charging capabilities. In the longer term we also expect that lines companies and retailers will offer reduced prices to drivers whose chargers participate in load-shedding at times of high network usage. This has been the case overseas and has been popular as a way to reduce the cost of charging, however the options in NZ are still limited at this time.
Furthermore in case there is interest, we have shared this statement recently on some other platforms when the question of 3G shutdown has been raised:
The 3G network that our Core units and some R-series chargers use is indeed scheduled to be shut down at the end of 2025. As someone has already mentioned, the modem in use on these chargers is not able to support 4G, and is soldered onto the main PCB such that it cannot easily be replaced with a more recent one. Unfortunately when we designed these products we weren’t aware when support for the 3G network would run out.
Our plan until now has been to contact everyone using a 3G charger in May 2025, to provide three options for them and allowing six months to decide before the deadline when the network ceases operation. Since these questions have been raised now, I’ll jump ahead and give some further notice - but there’s no need to make a decision until we contact you at that time.
For those that wish to keep using their 3G charger without cloud access (and thus without any reporting, scheduling or configuration capability), we can update your charger firmware one last time in November 2025. After the update it will become a ‘dumb’ charger that will simply charge when plugged in.
A second option would be to get a new E2 or X-series charger at a $300 discount. The discount can be applied to a hardware-only sale (where you arrange your own installation) or a fully installed option (where Evnex handles it for you).
Finally a third option is to get an E7 charger for $600. These are essentially identical to our current X7 charger but with WiFi only, and no support for RFID. We rationalised around just the X-series when we launched the E2, but still have some E7 units in stock which we’d love to see go to a good home.
At this stage there are still a few things to iron out - like how we’ll handle things if you’d like to take the opportunity to add a current sensor (to take advantage of solar diversion and home overload protection) if you’re going down the E2 / E7 route. So it’s possible that some of the details around the options will change, but broadly this is our current thinking.
Rest assured that these will be worked through before reaching out in May, and we certainly don’t want to leave our valued early adopters stranded.
