Did I get scammed? 2015 S loses battery capacity FAST

Fri Sep 08, 2017 2:11 pm

Hi, new Leaf owner here! I bought a used 2015 S from a second hand dealer in the LA area for $8200. I've been a little surprised by how quickly the battery is drained. Despite many attempts, I can't get LeafPro to give a full accounting of the battery. It gives some readouts but not the SOH or other seemingly important ones.

The car has 43,000 miles, which is a lot for a 2-yr-old EV. (Maybe that was a red flag?) It starts at 13 bars and quickly loses the first bar. That would be normal enough, but I find it loses capacity a bit faster than the guess-o-meter predicts, and that's driving conservatively often without AC. The real range seems to be 50-60 miles.

I've read about the possibility of the meter being reset. That would be surprising to me given the utter lack of knowledge these dealers had about the Leaf and electric cars. But something seems up.

Any way, I guess my question is if anyone knows of a person/mechanic/dealer in the LA-area that can do some sort of diagnostic for a newbie like myself?

Thanks so much for any guidance/advice anyone can offer!

For starters, the GOM is useless. Don't expect anything logical from it. Secondly, there are only 12 bars, so you couldn't have 13. We need to know how many of the SMALL bars there are. That will tell us about the car's current capacity. How far have you run the car down? If you're leaving 2 or more bars, there's a lot more range than you think there is. Finally I'd suggest posting a screenshot from LEAFSpy. It doesn't make sense that you can't get the SOH and other stats.

He's talking about charge bars, of which there are also only 12.

Highway speed drains range, so if you are driving 65 or faster, that's the problem.

You can estimate the health of the battery pretty well by doing a range test.

  • Note the current state of charge (SOC) BEFORE you start driving
  • Reset the energy economy gauge and trip counter BEFORE you start driving
  • Drive on a highway, in good weather, maintaining 50 mph until the state of charge has dropped by 25% from the SOC you noted earlier
  • Get off the highway ASAP and note how many miles you drove and the energy economy reading on the dash

With the above information, you can estimate the kWh capacity of the battery. For example, if you drove 20 miles @ 4.5 miles/kWh then here's the math on the kWh consumed:

20 miles / 4.5 miles/kWh = 4.44444444 kWh consumed by an SOC drop of 25%

Then, multiply that number by 4 (i.e. 17.7 kWh) to get the estimated pack capacity in kWh. Report back that kWh calculated value

Thanks for all the replies so far! Yeah it has all the small bars still there, 12 not 13. The lowest I've taken it is down to two bars. I've mostly driven on the highway at 70mph so maybe it's just that. But man does it lose bars quickly.

The efficiency graph seems to show a steady drop in energy economy, I'm guessing since you got the car. That is probably the highway speed, and maybe low tire pressure. I suggest you inflate the tires to 40-42psi cold, and drop your highway speed to 65MPH (60-62 would be even better, if possible).

There is nothing wrong with driving 70 mi/hr as long as you understand the range is lower. There is substantial range after the first Low Battery Warning and still about 5 miles after Very Low Battery Warning so you are leaving significant range in reserve if you never take it below 2 bars. I doubt that your capacity bars have been reset because your range sounds reasonable for your driving conditions. I recommend at least 40 psi tire pressure for best handling, tire wear, traction, and range because the Leaf is a heavy car. I personally ran the original tires at 44 psi (maximum listed on sidewall). I run a little higher with my replacement tires that are rated 51 psi.

Jneumark: The Leaf Spy screens you posted were totally useless.

You weren't connected (yellow box in the lower right) and you didn't post the screens w/AHr, SOH and Hx while connected. That's what we need.

See viewtopic.php?p=504419#p504419 and the video there.

Thank you very much for posting that tutorial! Seriously a lifesaver. Got it working, here are the readouts:

So it seems like it's in good/decent shape, or what you can expect from a 2015 with 43K miles?

SOH vs Hx seems to have a large variance.
