I purchased the Mustart off of Amazon which is basic. Charges at the 21 to 22 miles per 60 minutes, but all controls have to be done via InControl as Mustart didn't have a Wifi and app option.
I haven't seen the JuiceBox App, but the ChargePoint allows you to set charge time, monitor usage over time, etc. It's a good looking App. I may switch charging stations later, just to get the electrical consumption details.

What do you mean about levels? Are you trying to set a %Charge for your battery? I'm not sure if any of the chargers can do that, even though they project time remaining.
JuiceBox has posted on Amazon that they cannot set the charge to stop at a specific % of charge for the battery. Here's their quote " No, it cannot read data directly from the car. Our Pro-wifi unit will give you alerts to your cell phone when the charge session is complete. You can set the charger to the car's current charge percentage, then as you check on the charge this will tell you how much you have remaining to charge. I do not belive there is a charger out there that has this capability to speak directly with the cars system"

Sounds good. Thanks!

How are you all making sure you don't charge to 100% every night then?

I don't worry too much about the 100% state of charge with the current battery management systems and chemistry.
For the most part I'm at 75% during the week, and I plug it in when I get home, and unplug it when I go to bed or after 2 hours, so it replenishes what I used that day in a couple of hours and doesn't reach 100%. On Friday night, I take it to 100% because I've been driving longer trips of about 150 miles + round trip. The car isn't stored for a long period of time at 100%, nor is the charge a fast charge, so the battery damage in my mind is minimal. Unfortunately, this is not a Set It and Forget It option, so I have to be more active.

If InControl worked properly and shut down the charging, then I would just set a two or three hour charging schedule to add 40 to 60 miles onto the car. However, InControl is a bit spotty. You can do the same with JuiceBox or ChargePoint. Set the number of hours based upon your current state of charge and the estimated number of hours to fully charge from that point.

WattAJag had made this very helpful post which should give you an idea of approximate time needed to reach a SoC based on your current SoC. I am copying his table here for easy reference. I believe this is based on 6.6 kW charging while the I-Pace on-board charger is 7 kW so your charging time will be slightly less to achieve the same SoC.

I do not have my car yet so cannot confirm if this works, but according to this video (at the 2:05 mark) you can actually set the charging to stop at a desired SoC on the JuiceBox. Maybe some kind folks who already have their car and have a JuiceBox can try this out and confirm?

I am assuming this is an approximation based on the "current" SoC that we enter in the app and the charge rate and not the "actual" SoC of the vehicle once the charging stops, but still better than nothing I guess.

I trust JLRs battery management software to do battery management. I plug the car in most days and don’t worry about it. We all know there is not 90kWh of usable battery, JLR giving a 84.7 kWh available and others stating in real life it is closer to 82kWh of real available, so exactly what is 100% anyway? Can anyone show me that when the car says it is 100% that equals 90???

Went with the JLR recommended home ChargePoint
32 amp with plug. The app showed it charging at 7.4 kW
when plugged in. I can stop it with the app if I want to.
Any one know how to find any of the following?

1. battery state of charge kW.
2 battery temperature.
:nerd:

And I was under the impression that the ChargePoint unit could be detached from
the wall for portable use, but it is a permanent install.

I have a ChargePoint Home 25, and like you, I have the plug in version. While it is not 'portable' like a cell phone, there are just 3 'slot screw's that hold the box onto the wall, so it can be unplugged, slid upwards (may need to loosen those 3 screws), and removed in seconds.
Like others on this forum have discussed, I use the known 20mi/hour charge rate of the ChargePoint unit to set a 'stop time' in ChargePoint app when I wish to avoid achieving 100% SOC. If I'm at 100 mi range, I may set the stop time 4 hours out to add 80 miles and stop there.

neither of those links provide new information insofar as when the car shows the battery is at '100%', what does that mean? Is it 100% of the battery pack size (90kWh) - likely not as they say the battery cannot be charged to 100%; so is it 100% of the 84.7kWh they claim is usable or is it 100% of what people (I.E. Bjorn) have determined is truly usable (~82kWh)? So when folks insist they need to stop charging at 80%, do they want to stop with the battery at 72kWh, 68kWh, 65kWh or something else & how do they know since all we have is a mystery gauge that states a %, yet we have no idea what it is a percent of...

JLR says they have a sophisticated battery management system that ensures battery pack longevity, yet there is an awful lot of angst about charging to 100%, which the car indicates it is at, but JLR claims it cannot achieve...so the questions remain, what exactly is meant by 100% charge in the I-Pace and why are there so many who do not trust JLR's BMS to do what it is supposed to do?

I have a feeling it is an issue along the same lines as some people still think you need to change the oil in your car every 2-3 thousand miles...but admittedly, I really no nothing about EVs but trust JLR to do the right thing. If they want me to stop charging the battery to 100%, they need to tell me that.

Well the best thing for a Lithium battery is appearently to keep the SOC around 35ish percent. So logically, if you drive 30 miles a day and every night you charge to "100%" which is in fact 97ish percent, then you keep the SOC substantially higher than optimal and your battery won't last as long. I think that's all it is. Or am I missing the question?

I see absolutely nothing wrong with charging I-Pace to 100% as shown on the dash.

OK if you drive 10 miles every other day I would not charge every night. Let it run down under 50% and then charge it back up. Likewise if you will not be driving for an extended period just let it sit partially charged.

If driving 100+ miles every day I would be charging to 100% every night.

The other issue to consider is cell balancing. This is done by the BMS to keep series cell strings or battery groups at the same voltage level. While balancing can take place at any charge level, I understand that balancing works best at the equivalent of full charge.

IMO even if you partial charge the vehicle daily it is still best to give a full charge weekly or at least once a month minimum.

Agreed. If you drive more you have to charge it to higher than 50 or whatever percent. But even someone who drives 100 miles a day could charge to just 80% to optimize battery life.

You can get some idea of what 100% "really means" by their published 84.7 KWh Usable battery range. And, you can be sure that most of that "hidden" 5.3KWh has to be preserved on the lower end. So, I would argue that when your car says you're at 100%, you're probably really somewhere close to 97-98% true.

So, I recommend that you generally charge to (displayed) 80% (which might be only, at worst, 75% true) except on those days where you really can use the extra range. And, it's unconscionable that the software doesn't make this easy.

SOC displayed is most likely the usable percent not accounting for buffer, so 100% is not full 90 KWHr rather 84, is that the question?

There is a mild advantage of charging to 90% that has nothing to do with the battery. Full Regen doesn't come into play until you fall to <93%. So your brakes will last longer if you charge to 90%. Plus whatever other benefits there are.

My five year old Tesla Model S still has 218 miles of range at 90% after 160,000 miles - it is definitely a better system than the Jaguar. I would like to be able to specify the max charge for the Jaguar. I'm sure the engineers would be able to add this feature. I usually charge the Jaguar every other day unless I need it to go into Phoenix.

Actually, this is likely off, slightly. The "unusable" part of the battery will be split with some at the bottom and the rest at the top. So, 100% is likely 87-88KWH - because 0% is still 2-3KWh because the car should NEVER let you get to real 0.
