Range loss without capacity loss on new battery

Fri Feb 21, 2020 9:57 am

I have a 2011 that's always been a CA car. Replaced the battery pack in January 2018 when the capacity was at 7 bars and range was averaging 55-60 since my daily commute is 50. Assume it was the lizard pack installed in 2018. Now two years later I'm still at 12 bars capacity by my range is dropping heavily. The guess-o-meter actually showed 65 at 100% charge when I got in this morning. Got to work 25 miles later and had 62 from hypermiling. The range has started anywhere from 65-95 over the past month but it was as high as 110 when new. It's dropping faster when I drive and I'm a conservative driver. Got home with 14 miles left one day after less than 60 miles of driving. No climate control running, just the radio and I live in one of the most temperate climates in the world so it's not weather related.
Had the local Nissan dealer do basic and advanced battery testing and they're showing no issues. Any thoughts on what might be happening? I bought the new battery knowing it would take me 4-5 years of driving to recoup the cost but now I'm wondering if I can make it that long given how fast it's dropping and my commute.

I suspect you really need to check out the battery with LeafSpyPro.

^^^^^^ What jvl said!. LeafSpy will allow you to see exactly the battery condition and capacity.

I’ve been using it for years on my 3rd Leaf. Right now I can see I’ve lost 4% of capacity on my 2019 since I purchased it 9 months ago.

Here are SOH, State of Health, screen snapshots of my original 2015 .

One is from 11/2015 with 460 miles on the odometer. It shows 95% SOH

Other is from 5/2018 with 10, 565 miles on odometer. It shows 85% SOH

I've got Leaf Spy running now and here's what I have from end of the day after my normal 50-mile commute and what I get first thing in the morning after charging back to 100%. Even though this is a 2011 Leaf, it is a new 30kwh battery.

I'm curious who you had install a 30kwh battery in an '11 Leaf, I can't believe it was Nissan.....
If it were Nissan they would have only installed the same 24kwh battery as OEM. BTW your photos don't show up :?

Also, I wonder if the OP realizes that the 12th bar represents 15% of the capacity. You can have 12 bars showing and have lost 14.99% or more capacity...

If you right-click you can open his images in a separate tab

He is at SOH of 88.95%, 56.75 Amp-hr

Oddly though his full charge is only 92.7%.SOC. Not sure what is normal but my 2018 at "100%" is usually around 98% in Leaf Spy.

It was the local Nissan dealer, but you're right in that it is still 24kwh - my mistake.

She has at least 2 cells that are lagging all the rest by ~17mV, cells #17 and 80, plus there may be others, but those stick out as easiest to see.

The cells may be defective, or maybe they will balance back up to the rest, but as long as they lag then the average voltage will be pulled down and the range will be affected (as observed).

i would recommend to drive the car down to a really low level, such as 1 bar on the "fuel" gauge, then take another screenshot of the cell voltages. This should show a bigger voltage difference if there is a defective cell. Then charge on L1 or L2 and let it go until it stops on it's own--no timer. This will allow the balancers to do their job for as long as possible. But a defective cell(s) can't be brought back into balance. Good Luck hope you get a new pack if the cells are bad.
