[Chasing Cars]

Same here!

Welcome to the forum.

Hard to judge from a two word post but at a guess, as JNealCox says, if the car is not charging as expected you have not fully activated the timer. Also remember, you cannot set a start-charge time, the timer works on a departure time.

Can you not set the timer on your charge point?

I have a JuiceBox 40. From the JuiceBox app, you can set two timers - one for weekdays and one for weekends. It's pretty simple, you set a time to start charging and a time to stop charging. I don't use this feature, but I assume what it does is shut off the power to the vehicle outside of the charging window. So if the vehicle reaches its target state of charge (SOC) during the charging window, it will stop charging. If it doesn't reach the target SOC, then the JuiceBox will cut off power to the vehicle and force it to stop charging at the end of the charging window. This makes sense if you're more concerned about avoiding times of day with higher electricity rates than you are about reaching the target SOC. My electricity rates don't change with time of day, so I will only use this timer if our utility asks users to conserve energy which they sometimes do during the hottest summer afternoons. In that case, I might set the JuiceBox timer to allow charging from 10:00pm to 6:00am then plug in the vehicle set to charge to 80% through MMI or the MyAudi app. In that case, charging would begin at 10:00pm and end at 80% SOC or 6:00am - whichever occurs first.

The JuiceBox has a separate function that allows you to enter the starting range in miles and the target range in miles. Note that you have to enter these figures manually because Level 2 EVSEs do not know what the vehicle's SOC is at any given time, and they only know the theoretical range rather than the vehicle's guess-o-meter range which is always changing. Presumably this function will turn the power to the vehicle off when the EVSE has determined that the target range has been achieved. I don't use this function because a) you have to manually input the starting range, b) both the starting range and the target range vary due to ambient temperature and the efficiency of your recent trips and the EVSE doesn't account for this and c) I'd rather think in terms of percentage SOC than range because that's how Audi recommends you preserve battery life (i.e. don't charge past 80% unless you need to). I don't find this function helpful at all, but you can't disable it so instead I set the current range to 0 and the target range to 222 miles no matter what the SOC is when I plug in so that the vehicle decides when to stop charging rather than the EVSE making that decision.

Additionally, smart EVSEs like the JuiceBox presumably can be controlled by your utility in exchange for lower rates. In that case, I assume the utility manages the charging window for you and it functions like the first example above.

The smart EVSEs do give you additional timer options, but they are limited because Level 2 EVSEs don't share data with the vehicle. I like the JuiceBox for other reasons (especially the 25' cord, the ability to vary the amperage and the additional energy usage metrics).

I read your post and have a Juicebox 40 which I have used for several years with other electric cars. I bought my 2019 e-tron last week and have been struggling to get it to charge in a TOU environment. I was frustrated and unsuccessful for a number of days. Using the posts on this forum, I was able to get it work for the first time last night using the MMI shutdown screen technique (red bar activated). Who would have known.....

I called Juicebox tech support during my trials and they had their own "notes" about how hard it was to coordinate with an Audi e-tron and suggested that I just use the e-tron's timing capability (which at the time I had not been able to make work).

My dream is to get the e-tron to work with the Juicebox like my past Tesla, I-Pace, and XC-40 Recharge. By this I mean: In the car you set the max limit of any charge (e.g. 80%). From there the Juicebox does all the other work/scheduling. You use the its App to set TOU and turn its charging on and off. You plug the charge cord in and walk away. This has not worked for me so far with my e-tron. The car starts charging right away when it is first plugged in and the Juicebox fails to "time" its charge. It just charges. It is like their handshake is incorrect during the initial plug-in. Can you please reply to this post that you have your Juicebox 40 performing in this way? Thanks in advance for the help.

Anyone reading this post, please reply if you have a Chargepoint Charger behaving in the way I would like to get my Juicebox charger to work.

Yes, I have it working exactly like you want it to. I have a 2022 e-tron 55 SUV and a JuiceBox 40 purchased in fall of 2021. I just tested time of day charging using only the JuiceBox and it works fine. Here is exactly what I did:

1. I didn’t set any timer in the e-tron, but max charging was set to 80%.
2. In the JuiceNet app, I opened Settings/Smart Charging and turned on the switch for Time of Use.
3. I changed the appropriate time setting for when I wanted to charge (weekdays and weekends have different settings).
4. I closed the Settings screen.
5. I opened the e-tron charging door using the button.
6. I plugged in the charging cable. At this point, the JuiceBox started flashing yellow but charging did not start because the time was before the charging window. The light at the e-tron charging port was dark. The dashboard display showed an hourglass. The MyAudi app said “Charging not possible. No mains power available.” The JuiceNet app said “In use. Waiting for time of use period. Charging will start at 5:00pm.”
7. At the scheduled time, charging started automatically.
8. Charging stopped when the battery reached the target SOC of 80%.

Hi - I wanted to update you on my progress with my Juicebox and e-tron charging saga. I tried your approach, which I agree should work. My dream, oulined above worked for my previous two EVs (I-Pace and XC40) with the same Juicebox. The Juicebox Tech. guy had earlier said that there should be no difference with the e-Tron...except that there had been some interface problems with the plugs. I followed your approach, step by step, and my Juicebox would not play ball. I also tried using it in pure "dumb" mode. I could get it to charge in "immediate" mode...but, could not make it work when I set the Audi up to be incharge of the timing (with the red thermostat). As a "brain check" I used the Audi supplied charger one night with the same Audi setup for it to be in charge. It worked great! So, I concluded that my Juicebox must be the problem. It seems to lose (drop) contact during the time delay between when it is setup and when it is supposed to act.

I happened to have a new Chargepoint charger that I got free with my last EV...that was replaced by my 2019 e-Tron. I installed it and tested it last night. It worked Great! It was incharge and the Audi only had to accept the charge at the timing dictated by the Chargepoint...and the Audi had to limit the charge to 80%. It all worked great.

I want to thank you for your work/help on this. Hopefully, this thread will help some other folks weave their way to better charging solutions.

9/6/2022 - Well here is an update. I decided to go back to Enel (Juicebox) and ask for more help on figuring out if their Juicebox or my 2019 etron that is broken. It had to be one or the other. I really got no response...I wanted to test a new one and send it back if it did not work. Their solution was that they would sell me a new one.....when I did not even know if it would work. I have since found other posts in this forem about problems with etrons and the Juicebox. My recommendation would be to not buy a Juicebox if you have an etron. It did work great on both my I-Pace and an XC-40 ReCharge.

 

[Rwolf01]

LOL. This is absolutely NOT a dumb question. The way the timers work in the etron is not straightforward and is poorly documented....

Visions of Brazil.... "You have to say the number!"

Ok, I am officially lost when it comes to setting up my charge time, When I set the preferred window, and then set the timer, it says waiting for timer but it is waiting for the END of the window rather than the START Any suggestions>?

You can't set a start time. The car will calculate start time based on your state of charge and the departure time you have set. Expect it to be fully charged about an hour before departure time. The preferred charging time is not really useful, and doesn't actually have anything to do with the charging timer.

Welcome to the forum. Should you read this thread you will come across the answer to your problem and more besides!

The preferred charging time is not really useful, and doesn't actually have anything to do with the charging timer.

While the answer to @coltrell's question is in this thread, I'd suggest your response is only partially correct. It is true that, when using the e-tron's timers to control charging, you don't set a start time but rather a finish one.

However...
The preferred time window is for people with cheap off-peak electricity rates (typically overnight when most EV charging is done) and it is very useful for those people - it saves me a fortune! If you set up a preferred window the car will seek to mainly charge in that period but see below.

When on a timed charge the car is not fully charged about an hour before departure but instead it aims still to be charging when you rock up to drive the car away - thus giving the battery a couple of kWs of power right until you unplug it. This is to condition (albeit minimally) the battery.

If this seems self-contradictory, the car will actually eschew fully charging in the preferred window (even if it easily can) and instead maintain ullage in the battery for about a half hour of charging to be done before the finish time.

Having read through the post I have a slightly different problem in that I can’t remove my timer settings. I have recently moved to intelligent octopus working with a zappi and etron 70 plate.

With intelligent Octopus the theory is all timers and settings are off on the car and charger and it decides when to charge you. But it’s not been working and I phoned Octopus and they say it’s because the cars setting are overriding it.
The problem is with the timer it keeps coming back on. Last night timer 1 was set at Friday 17:20 so I turned it off and sent to car on app. This morning there’s a new timer set at Saturday 2:55. They are so random and the car is clear of timers too (I think) but they keep appearing but I just want them off. I’ve read s few forums but can’t see this problem. Please can anyone help

 

[Chasing Cars]

Welcome to the forum.

If you are using IO then you ignore the timers on the car. These will get set at what will apear to be random times, just ignore.

What you do need to do is ensure that the maximum charge set in the car is equal to or greater than the charge you want. If you don't the car will stop the charging when it has had enough.

Then just set the percentage charge and departure time that you want in IO.

When you plug-in, IO will tell you on it's schedule exactly what charging times it has set for that particular night but this is only for information no further action is needed.

At the end of the day with IO (other suppliers are available) you hand over charge timing to their servers, the car timers are redundant.

 

[Robhudds]

Thanks for the quick reply. I think I have that set up already kw that but doesn’t seem correctly working. Last night MMI set to 90% and IO set to 85% but it stopped at 80 with plenty of time left to charge and the timer that got applied was Sat 2.55 about the time it stopped.

then I’ve just taken my daughter to work got back and plugged back in and it’s started charging again now out of cheap tarriff time. This charging I understand IO should knock off but doesn’t and when I call up IO they say it’s because car or charger are overriding it.

I have a zappi charger which I used to set on eco+ with a schedule when I had octopus go and worked alright but now set to FAST as instructions say to give the intelligence to IO but seems to be a problem.
I’d say I’m pretty tech savvy but this set up is baffling me even after researching it on line 😩
