Lexus UX300e charging schedule not working

I’m really struggling to get it to charge between 00:30 and 4:30 to make use of my Octopus Go tariff. The app keeps resetting to 7:00 start and ready by 7:00 so that might be the issue.

Ive also got the tariff and schedule set on my ChargedEV Smart Pro charger and I’ve set the schedule manually on the car. But when it comes to 00:30 it just doesn’t start.Any advice as to how to get the charge schedule to work??

You need to make sure "Charge Now" is "OFF" otherwise it will start charging straight away. Mine works fine set for a 7 hr charge starting at midnight on economy 7.
If not that, I expect some sort of conflict with your charger scheduling. I may be somewhat confused by your post as my dumb charger is just on all the time and the scheduling is done by the car.
Nice to see at least one other Lexus UX300e driver. I've had mine for 9 months and know my way round the car fairly well, so any other questions, post here.

Hi Can you help me on the same subject. Can you set the car charging schedule for more than 1 day at a time and also what is the Leaving time used for?

Hi, thank you for your reply. I think you are correct in what you are saying and I think the charger schedule is messing with the car schedule.
I removed the tariff info on my charger app as that may have been overriding the schedule on the car. I’ve then set the schedule in the car itself and on the Lexus app and for the first time it charged at 00:30 yesterday. So hopefully that’ll now work going forward!

Yes, I can't say this is clear in the user guide.
A couple of important points.
You must set "charge now" to off.
I never used "Depature" as I never set off from home at a fixed time. My understanding for departure is, you want to set the car to start charging to give you a full battery at set departure time and optionally to set climate control to pre-condition the car.

So, to set a charging schedule to match off peak period - its Vehicle Settings - Charging Settings - Charging Schedule.
Select - Scheduled Events - then +Add - then select "Start" for the charging mode (not Departure)
Then set the time you want charging to start
You must then ensure that the days you want to charge on are set to "ON"
Select Save to store Settings.
The big flaw for some is that you can only set a start time (unless you select Departure mode when you can only set an end time) so you can, if your battery is low, overrun the off peak period. With 7 hrs off peak at 7kW, that rarely affects me.
Once you've set this, it is very important that if you use a granny charger or other AC supply, you have to set "Charge Now" to on.
It's an imperfect system.
The Leaf was much better where you could set start and end times.

Thanks for the above but are you setting your charging schedule on your charger or car? If car what app are you using as I do not have all those vehicle settings scheduled events etc

My charger has no way to set the charging times. The progeamming is done from inside the car using buttons on the steering wheel. Everything I have said refers to the Lexus UX300e. The user guide may well be the best place to look for more detail of the charge settings.

Lexus Link is the only app I have and I have never seen a way to set charging schedules from the app. Do you have a different app?
The most useful thing in the app that I have found is to start climate control remotely, and it work consistently for me.
Let me know how you get on with setting the charging schedule.

I’ve been getting to grips with charging my UX300e too. It’s not as intuitive as you’d hope!

First problem I had was the car starting to charge immediately rather than waiting for the schedule that I’d set on my home charger via its app. I thought it would be enough to set the schedule in the charger’s app only, but apparently not.

I read on this forum that the Charge Now setting was likely to be the problem here, so went into my car to turn that off via the settings menu found using the arrow keys on the steering wheel.

It wouldn’t let me highlight the Charge Now setting to turn it off… I had to create a charging schedule first. Creating a schedule and enabling that schedule turned off the Charge Now setting. I’m on an Economy 7 tariff so I created a charging schedule in the car to start at 00.30, which matches the schedule I’ve set up on my home charger.

For anyone looking for the charging schedule settings in the Lexus Link app, you access it via the Home tab’s % charged button. It doesn’t jump out as being a button, but tap the percentage and you’re shown the Remote Charging page that includes your current charging schedule and other settings.

it’s currently showing “Waiting for charging” and the schedule I set in the car is confirmed in the app, so I’m hoping this has solved the problem.

Thanks re accessing the charging schedule from the app. I had seen this before but not realised you could edit the schedule using the app.
As for the schedule working, my charger is completely dumb ( I like it that way) and once I have set a schedule from the car it all works fine. Unfortunately if you set your clock for daylight saving, you need to chage the schedule to match the E7 times. I hope you get it working but agree its fiddly. I preferred the Leaf for setting a charging schedule.
Apart from that, how are you getting on with the car?

A note here to present my recent experience with problems with the charging schedule.
My car is set to start charging at 11.00 pm every night when the E7 night rate kicks in. Normally, I plug in after my last journey and wake up to 100% charge.
A couple of days ago I forgot to plug in before 11.00pm and did so at about half past. Next morning, I still had 13%
I guess once the car reaches the set charging time it sends a signal to the charger which checks if the charger is plugged in. If it isn't, clearly nothing happens. If you plug in late, like I did, the charger never receives the "handshake" at 11.00pm and so charging is not initiated.
I assume something like this happens when you set a timer on the charger itself and in the car.
This may apply to other cars but I never had that experience in the Nissan Leaf.

Struggling with mine. It either charges straight away or does appear to work with my SyncEnergy EV chargers schedule as the Lexus scheduler will just charge to full, outside the cheap rate slot of my tariff.

The problem I think is the Lexus is either scheduled or charge now, you can’t set both to off! Ever get any further with this?
