Congrats and welcome to MNL.

I was at a Nissan dealer this past week considering a 2019 SV (no Pro), but the lowest on a 3 yr was $3K plus $350/mo.
They indicated that in the next few weeks they might have a Plus. I'll wait and see how the 2019s sell and how motivated Nissan
is to "move" the 2019s this summer.

I've been a little concerned that the LeafSpy app might not communicate with the 2019 Leafs. Are you aware of the LeafSpy app
that runs on iOS & Android? It can provide a lot info on the Leaf's battery. There's a free version for download. You might consider
downloading the app and providing MNL some battery data about your new Leaf.


I downloaded the latest iOS LeafSpy Pro from the Apple store, version 1.7.38. OBDII scanner is an LELink 2 for Bluetooth. It connected right up and seems to be working fine. The Model Year settings had dropdowns for 2019 and battery size 60 kWh (not 62, but close enough). I'm still tinkering with it, but once I get some good logs I can post some data such as the SOC at the knee requested by DaveinOlyWA. Is there other data that some might find useful?


Awesome!!

Yeah, add anything that seems interesting. Ahr would be good. kwh available at full charge. GIDs at full charge.


Here are some LeafSpy readings during and after a topping off charge. This is with an L2 charger.

Just before current ramp down (knee):
SOC = 97.57%
GIDs = 759
Volts = 403.6
Pack Amps = 15.0
OBC Out Pwr = 5.9 kW

At end of charging:
SOC = 98.6%
kWh = 59.4
Ah = 173.37
Volts = 403.5
Temp = 67.3F (max)
GIDs = 767
230.2 Miles -> 5% @ 4.0 mi/kWh

When my battery was in its first 2 years, if I kept it at 55 (highways around Chicago are still 55mph), and let it drift up and down a bit on hills, I could keep it at 5 miles per kWh. Even with light AC. Now that my battery is lower and I have grippier tires for the snow, I don’t get close.

767 Gids seems about right. My 2013 never showed more then 257 Gids, I think due to the early advice of never charging about 80%. That will feel like a full 3x range assuming the efficiency gains balance the additional weight of the car.

What efficiency gains were made with the e-Plus?
#1 Leaf SL MY 9/13: 74K miles, 48 Ahrs, 5.2 miles/kWh (average), Hx=70, SOH=78, L2 - 100% > 1000, temp < 95F (35C), min discharge (DOD) > 20 Ahrs
#2 Leaf SL MY 12/18: 115 Ahrs, 5.5 miles/kWh (average), Hx=98, SOH=99, DOD > 25%, temp < 105F

Nice. Now we need to get on a fast charger and see what happens. That 767 GIDs makes my high of 514 GIDs look a bit... "pedestrian" :)

Hmmm … today in Norway Model 3 sold 15x Leaf.

GID (energy) = K x kWhr = K x V (battery voltage) x Ahr / 10^3, where K is a Leaf assumed constant defined by those
that basically decoded the data on the CAN bus accessing the Leaf's BMS

Why not simplify the discussion by using a typical/relatable battery parameter? Since V for the Leaf's battery is essentially
a constant also over the Leaf's usable range, then the simple and key Leaf battery parameter to monitor is Ahrs of the battery.
Remember, most all batteries' capacities once the voltage is assumed, are rated in Ahrs. For one's typical ICEV battery,
the 12 volt lead acid battery's capacity is measured in Ahrs. Why use/monitor a non-standard/unique battery parameter when
discussing the Leaf's battery when other BEVs, e.g. Bolt/Tesla, use the standard terminology? Using the term GIDs doesn't
really lend any more useful info when discussing the Leaf's battery, and probably confuses those new to the Leaf.

I don't agree with this statement and I always thought that GID's were created to take into account just this fact. The capacity of the battery can't be calculated by just multiplying the voltage at 'full' times the Ah at 'full' since the voltage will drop as the Ah are used. It takes a bit of calculus to measure the area of the discharge VA curve to find the true battery capacity.

For the footnote, they said
1. Targeted EPA range for Nissan LEAF S PLUS only. Actual range will vary with trim levels, options and driving conditions. See Customer Disclosure Form for details.

This seems to lend credence to higher trims possibly having a lower EPA range rating.

Hope this isn't a repost but https://www.fueleconomy.gov/feg/Find.do ... 6&id=41277 has the EPA range rating numbers.

I haven't physically seen the Monroney sticker for any Plus Leafs since I've not seen one at a dealer or auto show yet.

No trim level specified (so by process of elimination would be S) https://www.fueleconomy.gov/feg/Find.do ... 6&id=41277 says 226 miles. SV and SL are 215 miles.

Please don't PM me with Leaf questions. Just post in the topic that seems most appropriate.
