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.

Loving the car despite these little wrinkles!
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.
