We’ve now got a good diagnostic test which we can perform remotely, plus a fix for the issue, and will be reaching out over the next few weeks. For most of the affected users the cable will need replacing (these need to be shipped from NZ hence the timeframe).
Tom
Do we have to reach out for you to check our units or are they just being checked ? I’ve been waiting for a fix since last November.
Hi Tom
That is good news to finally know you have identified the issue and the fix.
From my side since my charger was swapped out, including cable, I have run a number of tests charge session and I was able to achieve a constant charge rate at 6.9kW.
How is the process going to work for this? Does Evnex organise an electrician to come out and replace the cable and cover the costs involved?
Tom
I’m in the same situation but much worse - mine averages about 5kw despite the temperature being well below 20 degrees. It hits 7kw for a few minutes and thats it. Last session it took 4 hours to put 19.8kw in. I’m on three phase. Same unit.
Any updates to this? Anyone been contacted yet?
I got an email on the 5th of May. I emailed them back on the 10th. Just awaiting contact from the electricians at this point, I think.
I have noted even with the cooler weather in Brisbane, the cable is still running quite hot near the wall unit and throttling a lot.
For anyone else monitoring/reading this who’s awaiting the cable replacement; Electrician rang this afternoon. I disconnected my car prior to his arrival. New cable installed. I only got about 35mins in (after a short break due to schedule cut-off) , but it sat on 7kw(ish)
Will report after a sustained charge session after work tomorrow.
which units does this affect, E2 Plus user here, unfortunately I can’t verify if I have the problem without maybe borrowing someone elses EV as my leaf only does 3.6kw
The cable is the affected component so it could be any chargers in the E2 family (about 1 in 100 were affected). Our supplier has identified the cause and applied a fix, and we have run a diagnostic test which identifies affected units. The test works at any charging speed and any ambient temperature, so will be able to pick up a charger which only ever runs at 3.6kW.
What about chargers that are currently sitting idle. My car delivery got pushed back to mid June so my charger is currently disabled/locked.
Is there a timeline at least for people to find out if their units are impacted?
My cable was swapped out yesterday (I am in Perth) and my average charge rate of 5kwh has gone straight to a continuous 7kwh. Previously it was derating to 2kwh and then up to 7kwh and then 5kwh and so on but with the new cable it is locked at 7kwh. Thank you, Evnex. Hopefully this gets sorted for others ASAP.
Taking a LOOONNNGGGG Time in Victoria. Still waiting…
This mirrors my experience.
There is still a minor discrepancy between the charger and my car, The charger reporting 7.2~7.4 and my car reporting 6.8~7.0, but I am happy with the consistent 6.8 (car side). I felt as though once we got the second car, the throttling was becoming more noticeable due to not having roughly 20hrs of idle time anymore between charges, as I’m now charging mine from 1-3pm, then the partners car from 10pm to midnight(ish)
Got mine fixed a few days ago in New Zealand. Only took the electrician about half an hour including testing. I initiated it by calling the Evnex support number and they very quickly looked at my charging history from their end and confirmed the issue.
Have done a couple of charges on it now and it is working perfectly, staying right at the maximum 6.6kw that my car accepts for the duration of the charge. Before the fix it was starting at 6.6kw then dropping down to 5kw after about 15min.
Hi, have just stumbled across this thread. We are in Christchurch NZ so you will already know how cool our garage will be this time of year, had our E2 Plus installed in Feb and yes looking back through charge history it is quickly dropping from 7 to around 5KW. How can we get our unit checked and cable swapped out?
together with the fact that scheduled charging seems to be broken for our car (Jaecoo J7 SHS) I am starting to have buyers remorse with this unit 
Yes we need to replace the cable on your charger. I’ll tee that up with the support team who will be in touch next week.
As for the Jaecoo issue, we are actively investigating a path forward.
Tom
Thanks, look forward to hearing from the support team. Let me know if I can help with the Jaecoo issue, happy to test etc.
