Zoe not charging / DRM of the battery
There is always a risk of listing the bad things, which could easily lead to the false impression things are “wrong”. On the other hand, it is nice to have some sort of repository of issues and their solutions. One of them is this one.
Both a neighbour of mine as well as a driver in the UK had the problem that the car refused to charge. Her “nose” gave a double blue flash. From what I have understood there are two possible issues:
- the car is accidentally in timer mode. Check your R-Link for the timer settings (though there should be a clock symbol in the display), and your app;
- the TCU is defective.
In both cases mentioned, replacing the TCU by the dealer solved the issue.
It is kind of interesting as it suggests that Renault implemented the battery’s “DRM” through a mechanism that it will still work, but not charge anymore. It sounds as a rather safe approach as you’d stop somewhere on a safe spot to charge anyway. What is not very very OK is that the car does not indicate in any way that the car disable charging because of a signal from Renault, or lack thereof. Now you’re basically clueless. The whole thing also suggests (yes, speculation mode!) that the battery needs to be unlocked on a regular basis and if it’s unable to contact big brother, the battery will refuse to be charged. On the other hand, I had a communication failure for weeks without additional problems. My TCU was not defective/replaced though. It’s an interesting subject and there is no clear cut answer yet.
Seems like I was wrong on the “DRM” as user Harm suggested in the comments.
My TCU is defective (no more communication with big brother, the app does not work anymore, no more updated of my charging history on the internet site, ….) for not year 2 years, but I still charge 😉
I think that my ZOE’s TCU is also defective. It all seemed to go wrong after the new MyZE Online arrived (but that may be just a coincidence). My last charge data is 22/2/16. I can’t remember the last time I had an ‘End of Charge Notification’ email. Also, I no longer get traffic updates.
There is no info showing for the SIM card.
I’ve informed Renault CS, but they are taking their time to reply.
Does anyone know where the TCU is situated? I’ve tried giving it a reboot by removing the fuse, and that didn’t help; but maybe reseating the SIM might.
I have no idea but also would be interested. Bummer. It seems a rather flaky piece of equipment.
This seems to be the box, but I don’t know Where it is supposed to be mounted http://renault-zoe.forumpro.fr/t4110p15-applications-disparues-apres-mise-a-jour#83272
Thanks Jeroen. At least I know what to look for now.
According to Renault, there is no DRM software in their EV batteries. https://twitter.com/Groupe_Renault/status/401387987331981312
Thank you for that Harm. The non-charging, fixed by a TCU replacement must have been a different issue then.
