Basic question on home charging

Post by Jabberwock » Sun Jan 10, 2021 10:53 am

Hello
My I Pace is coming this week and in preparation I have fitted an 11 kW charger since we happen to have a 3 phase supply. No smart meter or off-peak though, so not much point in entering preferred charge times. So I get the car home, plug it in and start charging. My question is what happens if it just left plugged? Does it get to 100% then stop or keep trying to top it up? The latter presumably being undesirable.
MY21 HSE Indus Silver, Light Oyster interior, Charcoal Ash Trim, Air Suspension, Active Suspension with Adaptive Dynamics, Fog Lights. Very satisfied so far.

It stops at 100% and only adds if there is drain (e.g. from preconditioning)

I don't currently have a smart meter or cheaper off peak but I do turn off my charger remotely when I get to circa 85% charge

The battery has an 8 year warranty (or was it 10 ?) so JLR aren't going to let "charging it the wrong way" damage it.
You can safely leave it connected.
If anything JLR were ultra conservative in their battery management originally and the margins above "100%" and below "0%" were pretty substantial. Those margins were relaxed a little last year when they'd gained some experience from real-world use, but are still there to protect it from getting too close to areas which could cause degradation.
I always left it (and the previous Audi for 4 years) permanently connected to an E7 supply so it could top up overnight if needed, without any ill effects.
The only reason to stop it from keeping 100% charge is if you want full high regen from the moment you start driving. There's a noticeable reduction for the first few miles otherwise.

Looking forward to free motoring. (barring the cost of all the kit !)

But is it still the case that the iPaces own system will never stop at 4am - it will always keep charging to 100% if it can. I know some use 3rd party apps or timers on the charger itself.
I’d hate JackiesJag to have to suffer the weeks of futile frustration that I did !!!!

You are quite right that the I-Pace will still draw power to keep charging even after the timed charging period has elapsed. Presumably this is because Jaguar thought the car should be at 100%, or as close to, at the set departure time. Dont think that they realised how penny pinching the purchasers of their s

What I do is set up the timed charging as per Abu Dhabi Dudes excellent video on YouTube. I have my charging period set to 0:30 to 04:30.

In order to stop the charge I simply use the MyPace app on my phone at 4.30am, then go back to sleep thinking of the 50p I just saved! I think you can use WattCat (Android) to automatically stop the charge at a specified %, but i haven't tried it, as I didn't want to muck anything up.

Because we are not doing many miles these days, I don't have to charge the car everyday. I have found that if I put the car on timed charging when it gets down to about 65%, a 4 hour charge (7kWh) will get it back up to around 95%. Even if I don't wake up to stop the charge using my phone, an extra 5% going jnto the car isn't a big deal for either me or my Octopus account!

Hope this helps.

Kind regards,
