Re: How to set the start charge time on a 2013 S model?

Just costs $8


That would work (I was skeptical but the specs do say 15A) but of course it's for 120 volt charging only. If you put a lot of miles on your Leaf everyday, there may not be enough hours during the entire off-peak time period to charge the car to even 80%.

EDIT: I looked at the specs again and although it does say 125v, 15A, it also says 1250 W. IIRC voltage times amperage is wattage. So if a Leaf can be expected to draw 12A at 120V, that's 1440W which exceeds this timer's rating.

Some 240 volt EVSEs like the Schneider EVLink (currently recalled by the manufacturer) and Siemens VersiCharge do have start timers that are independent of the Leaf's own timers. Plus you're far more likely to get at least 80% charging during off-peak hours even if you arrive home on VLBW.

Ummm ... That timer is 120v only. If you are charging at 120v you are probably going to need to need to start charging before off-peak and/or finish charging after off-peak. Basically, you will be charging whenever you can plug in.

If you are charging at 240v it's not "painful" to take advantage of off-peak. What can be painful is starting at the beginning of off-peak and discovering in the morning that you don't have enough juice for the day. Why should you have to worry about that? Let the car worry for you. Tell it you need to be charged by 7 AM, and it will be. If your off-peak ends at 4 AM, tell it to be charged by 4 AM. Simple! If the car needs longer to charge than the off-peak time it will start a bit early. With your scheme, if it needs longer it will end a bit late. What's the difference? You have the same amount of higher cost charging time either way.

OK, I'll admit that the car's calculations are usually conservative. With an SV or SL you could get a message when the charging ends. With the S you may have to go out and check a couple of mornings when you first wake up. If it has already ended, move the end time a bit later. Or, if you're lucky, you may have a smart meter which can tell you (via utility website) when the power dropped off.

Wow, I'm very grateful for this thread. I think I finally understand how to use the charging timer. I was very confused as to why it didn't work as I expected!

I do have one more question. The manual is very insistent that of the two clocks (dash and radio/nav), it is the nav-clock that is used for the charging timer. For us S owners, that means the radio clocks, presumably. But the radio clock seems to be 12 hour only... I can't find a way to set or check whether the clock is set to AM or PM. Am I missing something? This seems like it should matter for the purpose of the charging timer...

For the SV and SL models the timers are implemented as routines in the computer that drives the navigation unit. For the S model the timers are implemented as routines in the computer that drives the dashboard. Regardless of what the manual may say, does that give you a hint as to the answer?

Actually, the only place I see that "insistent" statement is in the Charging Troubleshooting Guide. And there it is a verbatim copy from the 2011 and 2012 manuals, and was correct for those years, but if you want to be picky is no longer correct for any 2013 model. For the 2013 SV and SL models the two clocks are synchronized, so the problem of "which clock" no longer exists.

Per customer support.

Charger timer on Leaf model S:

When you set the to time on to 5am, the timer figures out when it has to start in order to get a full or 80% charge.

Climate control:

Set the timer to 7am. The heater or AC will start in time to warm up or cool the car to 76F in time for 7am.

Not intuitive at all.

Planet4ever: Thank you so much for making the charging timer so simple and easy to understand. I too was not getting it, and now my car is happily waiting to charge according to it's end time. Yes!

Do you have off peak rates where you live? If So, I imagine the easiest way to do it is to set the end time when the off peak rates end (5 am?). This way, you know for sure no matter how dead the battery gets, it will only charge off peak. I also have an 2013 S, and the timer works just fine for me too, and I had a heck of a time with the manual. I ended up searching the web for the answer... that's how I found this forum! By the way, I read the manual so much the pages are starting to fall out! grrr!

Gee, my manual is sitting in the glove compartment but it has hardly ever been opened. I downloaded this:

It's gotten lots of use, but so far none of the bits seem to have fallen out. :D

I will apologize in advance but I still don't understand how to make my Leaf S charger start charging for me at midnight when my low rates kick in. I don't really care about the end charge time as my Leaf will be charged in about 4 hours and well before peak kicks in. I also don't want to get up to plug it in at Midnight. Nissan has made this very complicated for the S Model.

The simple answer is that you can't do that using the LEAF timer, but why would you want to?

If, say, your lowest rate is from midnight to 6 AM, what is the difference to you whether the car charges between midnight and 4AM or between 2AM and 6AM? Now, admittedly, if you sometimes have to leave for work before 6AM then it will make a difference to you. But ignoring that (or compensating by setting the end time earlier than 6AM) here is the score card for end-only as I see it:

Difference to you personally: None
Difference to the car: Less time waiting at a high battery charge, so (slightly) longer battery life.
Difference to your utility: None now, but in a future with many EVs, avoids a midnight surge.

The other answer, if you really REALLY want the feature, is to get an EVSE which has a built-in timer.
