2014 Leaf, lost battery bar #12, is this about right? Future battery health

Wed Jun 07, 2017 6:05 pm

This March, we purchased a used 2014 Leaf with 21,000 miles. This Leaf did not have the fast charging plug so it was only charged on Level 2 during its 21,000 miles before we bought it, and still only a Level 2 today. We use it almost every day driving about 30 miles on average and charge it every night with a Level 2, 20 amp charger. Range has always shown 90 ~ 95 miles and the battery indicator always shows 100%. The computer shows 4.4 miles per kWh. The car lived its first three years in GA, rather warm climate, but we now live in a cool climate in WA State.

Just last weekend, June 5, 2017, we noticed bar 12 was not on. It has been 3 years, 3 months since the car was purchased. The dealer said this is about normal, 3 years for the first bar to go on a 2014 Leaf.

Does this sound about the right time to loose the first bar on the battery?

Does anyone know if charging less than 100%, (timing the charge and unplugging it when it gets to 80%), can extend the future life of the battery?

What about running it down low a few times? Any chance of getting the battery capacity back or extending battery life?

We will bring it in to Nissan for the first 6 month check in a few months.

Sounds right for a GA car.
Do not bother wasting your money on the dealer check.

The good news is that it should stay an 11 bar car for quite a few years, in your climate. Just try to avoid charging it when the pack is hot (7+temp bars) and don't let it sit for many hours at 100% charge if possible, especially in Summer.

Yep.

OP: Your subject line is confusing. You have a 2014 Leaf, not a 2017. Can you please fix it? Thanks!

Oops. Fixed it to 2014. The dealer check is free, first one. I do have the slight click when stopping, so I will get them to look at that. ntb12-055b

So leaving it at 100% for a while is not good. OK, we'll address that. To bad the state of charge can't be limited like I heard the older Leafs. I heard they could be set up to charge to only 80%. Is there any way to hack the 2014 to only charge for a time limit or to a certain capacity?

Hacking is for smart people, I suggest a little arithmetic.

You know ...
Charge divided by charge_rate = time
The car has a timer

Sagebrush seems to be having a bad day, and sharing it.

No, there isn't a way to get an 80% charge limit, so you have to either use a charge timer (the easiest way may be to set a departure time 2 hours later than actual) or manually unplug the car after the number of hours that will give a roughly 80% charge. That and the headlights are why I'd be reluctant to lease a 2017.

Unnecessary

2014 LEAF user manual, pp CH21 - 25

Example:
You want to cycle the battery in the 30% - 80% range, equal to about 10 kWh
Your home EVSE is 3.3 kW, so it takes 3 hours to put 10 kWh into the battery
Set the start timer 3 hours before the end time.

Plug-in when the SoC is ~ 30%
You could fiddle with the timing every charge but that is overkill. So long as you plug-in between 20-40% SoC the battery will charge up to 70-90% SoC which gives you the benefit.

Yes, the in-car timer will work, but it is a bit cumbersome to use on a daily basis, especially when car use varies.

Would LeafSpy be recommended or is there another method to monitor the battery?

Also, has any one heard of a battery bar re-appearing by treating the battery nice?

Bars will sometimes briefly reappear, but I haven't heard of one returning and then staying.

Unnecessary


Yes, but not everyone wants to set a timer every day - they are a PITA. Manually unplugging is sometimes the optimum way to end a charge.
