Using Charge Timer is it good practice

Tue Feb 28, 2017 3:27 pm

I am a new owner of used 2015 Nissan Leaf S.
I usually use 40% of the batter on a typical day. When I get home I plug in the cable to Leaf and have set the charge timer to 6 am. Is this a good practice for the battery, so that it lasts longer ?
I use 110V charging.
I have noticed the leaf doesn't start charging until later and turns-off at 6 am. I usually leave the house around 8, the cable is still plugged in until then.

What you are doing is fine. You want to avoid charging to 100% and then leaving it there for hours and hours. This is especially true in hot weather.

Well, that is what you asked it to do and as LeftieBiker said, your approach is a good one.

There is one thing you should know about the LEAF and charging with the timer however. If you check the data using LEAFSpy where it reports the number of L1/L2 charges the car has had, it will report 2 charge cycles for every one time you actually charge the car. One cycle will get counted when you first plug in the J1772 handle into the plug and the car reads the amperage draw that the device you plugged in will allow (that will be 12.5 amps for the 120 volt charging cable that came with the LEAF) and a second cycle will be added when the car actually starts charging. It doesn't matter that the car "double counts" charging cycles when using the timer, just something to know if you are ever looking at the data that LEAFSpy reports.

Can you charge to 80% limit? Don't charge to 100% if you never need it.


It is recommended to have Level2 charger at home for everyday use.
It is more efficient to charge on 230V. Also much faster.
Even if you don't need charging speed you'd rather pay less for electricity over the year.
Short range EVs <30kWh -- Medium range: 30-60kWh -- Long range: >60kWh
Charging: Trickle <3kW -- Normal 3-22kW -- Fast 50-100kW -- Supercharging >100kW

Rosh, I have your same car... I say don't use any timer. The car turns the charging off when it reaches 100% anyway. Get the Level 2 (240v) charger ASAP, where you will have a much more useful car then.

Don't listen to the naysayers to only charge up to 80% The 2015 (I have it also) is fine up to 100% I charge to 100% DAILY, have 30K miles, and my battery is still like new. The only thing I do is not charge up to 100% and leave the car sitting over the weekend. If you are not going to drive the car on the next day, leave the charge at 50-70% so the battery does not sit fully charged for days at a time.

I have the time set to right before I leave. That way it's not sitting at a high state of charge for long. I have a 2013 US model so I also have the 80% option, which I normally use. If you have a 2015 US model you won't have that option. But 2015's from other countries do have that option.

I also do it to help increase battery temperature in the winter, right before I drive. It doesn't seem to do much, but I think it helps a little.

That battery charger timer can also allow you to charge when electric costs are low. In some places the cost of electricity is lower during the night. Do check with your electric company and make sure your charging stops before the price increases. I think that would be the most important.

If you can't charge to only 80% could you charge every other night? For an example, one day you go from 100% to 60% or 65%, then the next day you go down to 20% to 30%. If you'd get below 20% it wouldn't be worth it. And you may want the 100% for something unforeseen. But it would be a bit better for the battery.

I got burned a couple times when charging in the wild by forgetting to over-ride the charge timer and charge percent from 80% to 100%. So I turned both off a few months ago and my mental state is much happier. I was leaving notes for myself on if my timer was on and if I was 80% or 100%, and was always double checking. Plus I dreaded explaining to my wife how to adjust these details should she need to charge. Now if I find a free charger in the wild I just plug in and it fills up to 100%, and if I charge at home I can always adjust the charge time and percent with my JuiceBox.

There is a timer override button on the dash for just that purpose. Just press that until the center blue light goes on (on the dash). Then it doesn't matter what you have set for the timer (overnight charge / 80% / etc). The car will immediately charge to 100%. Easy.

Yes on your '11 and '12 but not '13 and '14 where the 80% option is separate from the charge timer and just pushing the timer-override button won't change a 80% setting to 100%, you need to actually change the separate setting to 100% to get 100% charging :)
