Re: Requesting Hx values for all 40/62 kwh LEAFers

Mon Jun 15, 2020 7:16 pm

The 2019 S Plus we picked up today (build date 9/19) for our teenagers after sitting on the lot for 8 or so months had a SOH of 98.7% and he 97.69%. Thankfully they kept it at 71% charge sitting on the lot and not fully charged. I will do some readings in the next couple weeks, but extrapolated from the 548 GIDs, it puts full Gids at about 750-755.

I do have to say that the S Plus is more efficient on the highway than the SV Plus. 60F outside, and I was at A solid 4.8 miles per kilowatt on a 20 mile north south loop at 53-57 mph (in the mile off of the highway post it jumped to 5.1). The SV I don’t think could do more than 4.5-4.6 max in the same conditions. The car feels lighter..but could just be because of smaller wheels. It makes me want to put 15” wheels on both when the tires are up for replacement in a few years.

Just put 17-inch Ecopias on the SV when the OEM Michelins wear out. Congratulations on the new car.

I like that idea. The 16 inch rims look nearly as nice to me. It’s true the 16” rims give you a solid 5% efficiency, so poof right back to new range.

Realize the S Plus has solid wheels over the wheel covers the S has so I didn't see a need or desire to want SV wheels. And yes, smaller wheels are more efficient.

During 2010 Prius reveal at the Detroit Auto Show we had a special preview invite from Toyota and got a glance at the engineer's notebook showing a 2 mpg difference between wheel sizes

When I pulled the car off the lot in my test drive of the car, I chriped the wheels. Something I have never been able to do in the SV.

I really wish, they would make the 16" wheels standard at all levels and let you pay to upgrade. I don't really feel like paying ...?? $500 or something to get new smaller rims and tires on our SV as range isn't really an issue. I just like the idea of being more efficient.

Let's see how the SOH and Hx hold up on this car.

A little late to this thread:
2019 SV Plus purchased 1/29/20

6/15/20 1457 miles. AHR=169.79. SOH=96.25 HX=103.12 ( A month and 500 miles ago SOH was 98.78, AHR was 170.72, and HX was 100.94). I'm getting 4.5 m/kwh. I don't drive the car every day. Most trips are short - less than 20 miles. I never use air conditioning. The Florida heat is murder on the 12V battery when all you do is short trips.
2015 S - purchased 11/2017. sold 1/2020
2019 SV Plus - purchased 1/2020

I doubt there is a noticeable difference in efficiency with equal tires. The Ecopias are lower rolling resistance than the Michelins so that combined with the less accurate odometer/speedometer will likely yield higher dashboard efficiency numbers for the S. The 17-inch OEM Michelins are easy to spin when accelerating and turning, but the rubber is so hard that they don't make much noise. If you want to improve the efficiency of the SV, replace the Michelins with Ecopias and run the Ecopias at 44 psi cold for best tread life and wet braking traction.

Except for SOC of 90% at dealership on pickup
Leaf has always been charged to less than 80%
and remained above 30% so far.
It took more than 5 months to show a significant drop
but now...this seems to be a wowser.
Maybe a bms algorithm fault?  Will the slide ever stop?
Any thoughts on what might be happening?
I am thinking of charging to 100% to balance cells. I do not
expect going to the dealership is likely to help.

I am not convinced keeping the car in the 30-70% zone is best for keeping the SOH high. Please keep sending updates. If it doesn't in the 94's, I have not idea.

I wonder if in 2020, they updated the algorithm to just take the full buffer at the 6 month mark.

I found the build date sheet in my new 2019 S+ yesterday hidden away. September 26th, so I should be due for its next rebalance in 9 days. Let's see what happens.

Maybe not, but it should still be best for battery longevity. If the BMS's reporting of SOH really isn't always the same as actual battery capacity, then treating the battery well may give you a worse SOH than treating it badly...
