Charging across midnight

I guess I'm missing something about the advantage of using a charging schedule. After reading the manual, my takeaway is that setting the start and stop times means it will only try to charge during that time. But if the example I read earlier about setting your times 12 hours apart (eg 6pm to 6am) the system won't calculate when to start charging to have your battery reach 100% at 6am. It will start charging at 6pm and stop when the charge reaches 100% which will most likely be before 6am.

For myself, when it needs to be charged, I just plug it in at night so I can have a full charge in the morning.

 

Folks that have variable price / demand billing can save money by charging during off-peak windows.

 

Okay that makes a lot of sense. We pay just a flat rate 24/7.

 

Yes totally wrong. I have to leave at 6:30am. No way to get a full charge without starting before midnight.

You can presumably avoid this bug by not setting an end time.

It doesn't sound like anyone on this thread actually needs it to stop charging at a particular time, so there's likely no downside.

The end time is not providing a "have it charged by this time" function (unlike the G4) - it just allows it to be stopped before getting fully charged. Main usage would be to avoid more expensive electricity. There's no point in setting it to an expected departure time, unless you really want it to stop charging if you haven't left by that expected time.

 

I can give you my experiences with my 2024, GEN five. I don’t set any schedules at all, just plug the car in about 7 or 8 PM. It charges until midnight and then stops.
The only way I knew it stopped, was that I checked the app about one a.m. and saw the status as “Plugged In”, not “Charging”.
There was an option there to start charging, which I did, and it charged until it was full.
I guess if I have to set an alarm for midnight to just check the app, I’ll start doing that.
But that’s a real PITA, that Toyota could solve with a little better software.

 

I start my charge @ 00:05; five minutes pass midnight and get 99%-100% charge on my gen4 by 0430 in the morning. 110VAC outlet with an empty pack - right at the HV battery line; usually on HV when I hit my driveway.

 

Mine's ben charging without any issues past midnight since I got it two weeks ago. I have a charge schedule on the car based on when the lower overnight rates start before the peak rates start up again in the morning.

I wonder why mine works and others seem to have problems.

 

I'm wondering if it's actually the app messing things up, and the car is fine.

 

Looking at your original post, it may be because of the days of the week. It looks like you'll only get what you want between Friday night and Saturday morning.

 

I set my schedule using the app and I have had zero problems.

Who knows. Maybe it's a rare fault that not enough people have reported?

 

Have had success charging PP XSE Traction Battery across midnight at least two times now.
Set the schedule in the Prius.
Start charging at 9:30 pm, Stop charging at 8:00 am.
Avoids use of higher cost 'Peak' grid power from 4:00PM-9:00PM here where I pay my power bill.
I decided to charge at 120v, reducing the charge rate a little as comparedd to 240v charging. The middle of the night charging does not conflict with any other power usage at my home. I can charge all the solar power I have in the house solar system battery into the prius battery (sometimes its sufficient to fully charge the prius battery, sometimes its not). After the house battery is depleated, the power is provided by the grid, like a UPS setup.
Reduced power charge rate might extend the full power life of my Prius battery a little, and finishing the charge to 100% just before using part of it should also help the Prius Battery last longer.
Mine is a 2024 PP XSE I bought when it was ground-shipped to the dealer 12/30/223 (if that has any bearing on the software update that schedules the battery charging).
YMMV

 

Still seems to me you have no reason to set an end time. It's not providing you with any functionality - you don't want it to stop charging at 6am if it's not fully charged yet.
