How to use the "Charge period" in InControl

Hi,

I have one question about charging you iPace.
Searched the manual, and feeling really stupid I can;'t figure this out, but does anybody know how the "Charge period" works?

Like you see in the screen, I always set my cars preferred Charge periode start from 23:00 till 07:00.
I also set that my next leave is 8:00AM.

But strange enough (if you ask me), its fully ignoring those settings and always starting to charge immediately when the car is connected.
If I disable it after that, its not automatic going on at 23:00 again.

I should expect the car knows (since it know I need to leave at 8am), its having time enough to start from 23:00 since thats the preferred timeframe I added. Anybody getting this to work?

Regards,

Flip

I have an Open EVSE charger from the USA. This has the ability to set the charge time from the wall box itself. This morning I tried it so set the charger to work after a few minutes .plugged in and locked up. The wall box charger switched on but the car itself via the app showed NOT charging!!
Left the charger on ,opened the car unplugged and plugged in and locked again and of course it started to charge. Presumably this is due to the sensor wire needing to be giving a signal when the car is initially connected up. Not sure there is any way round this as I still have not been able to get the in car charger to work on timed basis.It always charges at 30A when plugged in.
Has anyone mastered the secret of timed charging yet please??
Hi,

As from my post of a little while ago, my I-Pace is to go to dealer tomorrow (Feb8th 2019) to receive a "manual fix package" from JLR which I am told will correct the issue with Preferred Charging. Once installed I have agreed to do a test overnight to see if the App / car system then actually works as it should, I will let you all know the outcome of this by Monday of next week.
Yes I will look forward to your report after your fix. Let's hope it is successful

Hi Brian. Really interested to see what happens. There have been so many people looking at this all without success for some time. No pressure! :lol: Hope it goes well and there is something concrete we can do too that comes out of this.

Hi all,

Just wanted to say hello (first post) and share my experience on this. I have the same issue as everyone else and came across this thread on the back of a google search.

I made a little video showing the problem and my local dealer sent it off to the JLR technical team for comment. They said they are aware of customer feedback and are working on a new software release (no release date given).

The crux of the issue is that currently it is a *preferred* charge period, not a *required* charge period and will only be observed if the car can reach 100% charge in that set period. This probably explains why people are saying that it sometimes appears to work and not at other times.

They clarified the current logic which I've pasted below.

If a Preferred Charge Time window has not been selected:
the car will automatically start to charge to 100%.
once the battery is at 100% charge it will be held there.
circa 3 hours before the selected departure time, the battery will start to be warmed up.
Note, if there isn't sufficient amount of time to charge the battery to 100% AND warm the battery, the car will prioritise charging.

If a Preferred Charge Time window has been selected:
the car will work out if the battery can be charged to 100% and warmed within the selected time window.
if yes: the charge port will flash blue and charging won't start until the selected time.
if no: the car will start charging immediately.
Note, if the Preferred Charge Time is less than 30 minutes in the future the car will start charging immediately.

Welcome, great first post and good job on posting up the charging information.

It is a pity that it has taken JLR till now to give a customer this information, afterall we have a JLR customer service person who posts on this forum and it is not like this thread is 2 minutes old.

This sort of ok information is really frustrating: I've never heard or read that there was battery conditioning 3 hours in advance of departure time. Here we have a ton of people complaining about range, and jaguar isn't giving us the tools to maximize it.

Communicate with us Jag! We will be supportve if you guys need to change something. Tell us how the darn car works!

Based on JLRs logic I have tried to charge the car using the charge period.
The car showed a charge time of 5hours 52 mins, so I set a departure time of 8am and a charge time for 10pm to 8am. everything seemed to be ok. The app and the car showed waiting to charge in blue, the charge port showed blue as well. 1 hour later the car started charging

I don't understand why JLR have made this timed charging so complex. I just want the car to start charging at the time I specify. I know that for 7 hours of off peak electricity with a 7KW charger I can only get a 46% charge. If I need a 100% charge I will adjust the start time or end time accordingly.
I sincerely hope that the update that Brian Scott has had done reflects this.

My I-Pace is still with the dealer I get it back on Monday (sometime) when I will then test the "patch" to see what it has actually corrected or not? As for charging times with a 7Kw home charger I have the following information for you.

So perfectly linear (apart from an anomaly at 5.1hr) that it is hard to believe - not that I doubt your data, Brian, but perhaps the car's interpretation of the data is overly simplistic? (There is a 0.1hr jump in the regular measurements at 5.1hr - if that is adjusted out, the charge speed is exactly 7.7%/hr and almost exactly 18.5mph all the way up.)
Is the "kWhr added" figure from the vehicle's data or a meter on your supply?
If you leave it on charge after 100% is first reached, does the displayed range change at all?
And did you really start this test at 0% SoC, or have you extrapolated your results backwards?

Hi,

The test was done starting from 10% SOC and measuring Kw with a "Clip on" sensor sending signal to a remote Minim+ monitor display unit (See picture)

Then monitoring time and charge etc until car showed 100%SOC on the app. Not sure why there was a "blip" at 5.1?

That's a really useful post, thank you but not really backed by real world experience sadly as well as being a really odd way for Jaguar to implement if true. (Let alone tell people about as it doesn't give this logic in the handbook! ) Using my powerwall monitor and Zappi timer p, I can see the draw by the car and know my car has been able to charge to 100% within my preferred charging period on many occasions, but whenever I put that charging period into the car, it charges straight away when I plug in, when the it would get to 100% in that time, and have more than 3 hours before departure time.

It's a bit moot anyway as this is a daft way to do this. All everyone wants to do is put in the cable and have it charge between the 2 times they set (and maybe have a % limit for those that want it) - this just overcomplicates any number of things. Poor show Jaguar- poor in how you've seemingly designed it, poor in how it's been badly implemented, poor in the handbook description, poor in communication to customers , and finally poor in fixing it. Quite astoundingly poor really.

Tried the same experiment last night and ended up with a similar result to you Ken. I't clearly not doing exactly what they said. Let's see what the software patch on brian's car does.

Until JLR issues a software fix, I've found a workaround that *usually* works. 1. Set a one-time departure time from inside the vehicle-not the app. 2. Activate timed charging on the goodbye screen. 3. Plug in - blue "Timed Charging" screen appears. 4. About an hour later the vehicle will start charging. Hit "Pause Charging" in the app. 5. The car will then wait to start charging until a time that would allow it to reach 100% charge by your departure time. If you only want to charge to 80%, enter a departure time 2.5 hours later than your actual departure time and manually disconnect at 80% charge. The process is tedious but seems to work.

I have tried this tonight and like you said it started to charge after an hour or so which I then have paused.
Will see what it does but certainly has been paused for the last 2 hours

Just to let you all know the "Patch" from JLR engineering was finally loaded onto my I-Pace on Monday afternoon, unfortunately the dealer fully charged my car before I collected it, so testing could not begin until later and I had a trip set for Tuesday. So I will post results etc on the patch update hopefully by Friday this week.

This is something I can't get my head around. Here we have Jaguar applying a one of software patch for something that concerns everyone.

What is the purpose of applying a patch to one car? Surely this must have been tested before release or is JLR quite happy to let customer do their testing for them?

If they have an example of the failure, a patch to fix it seems a logical thing to do. When I worked in software support we used to issue patches to individual customers to get to the bottom of issues, and to provide a fix, which subsequently benefitted all customers, even those not experiencing the problem. In-house testing will never replicate all the scenarios that customers can invent!

I don't doubt what you say but seriously? Every and I mean EVERY I pace as well as those owned by and parked on JLRs forecourt has this issue. Why on earth do they need an individual customer!

Correct me if I'm wrong but can all those owners with a working charge period please raise their hands..............

You think they can't replicate plugging in a car and setting a charge period. Come on, these are they people that sold it as a feature of the car.

So this is what we can expect from OTA updates. One of us becomes a lucky BETA tester.
 
#148 ·
^^^^^^^^^^^^^^^^^^^^ This is an excellent point, we are all beta testers to some degree but a number of the software issues have come about by sloppy testing, I too work in software testing and delivery and heads would roll over basic gaffs like this.

I would think that possibly Jaguar can search through their facilites and find at least one I-Pace that they have that they can test the software on for this rather than letting a customer test it? Surely?

Regardless of any future update I have resoled the issue. Ive swapped my 7KW charge master unit for a 7KW Zappi. This gives me the ability to charge from Solar as well as timed off peak charging. Anyone want to buy a hardly used 7Kw home charger, reasonable offers accepted.
