Hey Guys
Is there any way to program a delay charge beyond 11:45pm the following day ? I want to delay a charge until 3pm, two days from now.
I could maybe use the app to stop a charge tomorrow and then start it in 2 days ....
But I want to program it and forget it.

Nobody ever wanted to delay a charge more than a day?

Why would you want to do that? What's the point? Is the electricity going to be cheaper in a day or two?

Most common reason to delay charging, I suspect, would be to reduce the cost by charging during off-peak rate times (delayed based on rates). Another reason would be to finish charging shortly before departure time (delayed based on departure time).

I suspect most people want to have the car charged by the following day’s departure time, and there is no easy method of delaying for multiple days via the settings in the car. You could always create a timer delay for the wall plug power.

Don’t know if you could delay a full charge for multiple days by setting up a Delayed Based on Electric Rates/Departure Time schedule, setting the rate preference to charge during Off Peak rates only, and then setting only Peak Rates for the intervening days and Off Peak for the desired charging day.

For example, plug in on Monday, want to start charging at 3 pm on Thursday. Rate preference set to charge during Off Peak rates only.

Schedule Monday for Peak Rates all day. Tuesday for Peak Rates all day. Wednesday for Peak Rates all day. On Thursday, Off Peak Rates begin at 3:00 pm and end at midnight, scheduled departure time is 11:00 pm on Thursday.

Will charging be delayed until the first Off Peak rate period at 3 pm on Thursday?

Or perhaps charging will begin immediately on Monday because the manual reads, "Also, if the selected electric rate settings result in a very long charge completion time, the vehicle will start charging immediately upon plug-in. For example, if the electric rate table is set up with all “Peak” rates and the rate preference is to charge during “Off-Peak” rates only, then the vehicle will start charging immediately upon plug-in."

Perhaps if you assigned 1 hour of Off Peak rates from 10:00 pm to 11:00 pm and scheduled departure times for 11:00 pm on Monday, Tuesday, and Wednesday, then plugged in on Monday... the car would charge for one Off Peak hour only Monday-Wednesday, then complete the charge during the Off Peak hours on Thursday. I suspect, however, that because 1 hour of Off Peak rates is not enough to charge the car before the next scheduled departure time, charging would begin immediately when you plugged in on Monday.

The Point ?

Charge delay has more to do with reducing battery stress than anything. Car sits at airport for 3 days while Im on a trip.
I really don't want my fully charged battery to be sitting there for days in the hot sun and high temps, when I could delay the charge for a time closer to me being back.

And it appears you can start a charge (earlier than planned) from the app, but you cant stop a charge or plug in and start one from the app.

So, is your Volt is going to tie up a level 2 charging station at the airport for the whole time you are away? If so it seems like a waste of charging resources. Still, if the airport parking facility allows this, couldn't you tip the parking lot people and ask them to plug in your Volt on a the day you are scheduled to return?

Actually, it is better for the car to be on an active charger for the 3 days. As you know the battery never fully charges or depletes, that is why they last forever (my 2011 still get more ev miles per charge than Chevy said it would back in 2010 when it was new). While it's plugged in, the car will regulate the temperature of the battery, trust me, Im in Arizona and you want it always plugged in.

So, are you really suggesting that I park at a charging spot and NOT plug in ? That is somehow gonna be more appealing to you? How would someone else use the cable if I’m just parked there not plugged in? That’s a good way to really waste an EV Parking spot and P.O. anybody looking for one. And this mystery attendant I’m supposed to pay is just gonna happen to be working on the day and at the time I’m planning on returning ? Maybe YOU could drive to the airport and plug me in. Or, better, start valeting all the plug-in cars at the airport so the resources are used more efficiently. LOL

The adjacent spots all have there own cable. And, FYI, I’m using my own portable cable in an attempt to not deprive anyone of anything. I’m plugged into an outlet, at the base of the Level 1 EVSE that takes 14 hours to charge a Volt, Probably 30 hours to charge a Leaf. There is nothing outrageous about parking at an airline employee parking lot for a couple days or more.

Seems like a waste of online resources when snide comments are made to legit questions.

 

[jcanoe]

It was not clear from your original post that you were parking in an employee-only parking lot. Your snide comment was much longer than mine so I guess you win.

Why would you not keep it plugged in all the time and charging (especially if it's warmer or colder out) like GM suggests?

 

[Lotus54]

From what I understand, it would be better to just leave it plugged in for the three days. It will keep the batteries at proper temp using the AC (well, charge it back up if it needs the battery) and shouldn’t hurt the battery at all.

I read from Chevy it is best to leave it plugged in all the time. The onboard charge controller is supposed to keep battery in optimum condition. (Well, so I have read from Chevy)

For less than "months", just leave it plugged in. There are no conditions outside of "lightning strike" under which not being plugged in is better than being plugged in for periods of less than about four weeks. (There are some things being plugged in still won't change, but the important thing is that it's not worse.) Conversely *not* leaving it plugged in under most conditions won't do it any particular harm either. I mean, it's a car. It would be unforgivable if it couldn't easily tolerate a fair amount of neglect without critical failure.
