Battery Upgrades are very possible

[Stanton]

Sounds like if you got the 40kWh and your starting range was 170, then after ten years you would probably be about the 100 mile mark which could meet your goals.

Definitely...and I hope to keep my Leaf another 10 years (already had it for 10).

If you kept your tires stock, remind me your concerns about the additional 22 kWh?

Also there maybe one more reason for 64 kWh upgrade that I just thought of. Most 62 kWh batteries will be less than 1 year old and have little mileage on them / down time. I wonder what the probabilities are of you getting a hold of a fresh 40 kWh battery?

That's really the trick: finding a "good" battery pack (no matter what the size). I've seen a few 40 kWh packs pop-up around Tennessee (we all know that's where Nissan builds their US packs), and who's to say that Nissan won't make packs available down the road (they seem to coalescing around 40 kWh on the bottom end)? While the price may not be good, we know they will be "fresh". Of course, this may ultimately be a "service" (with a fee) by whomever does the battery swap.
I also use Michelin Defenders (on my second set actually), but the bottom line is: I just don't want to mess with the additional ground clearance issues.

Stanton, Alozzy and SageBrush;

When one does decide to a 'salvage' yard battery, Dala has laid out a really cool tool for assessing the battery SOH on the palette, pre-install!

See for example:

1)
https://www.mynissanleaf.com/viewtopic.php?t=30475

and

2)

https://github.com/dalathegreat/Nissan- ... ry-to-OBD2

From what I'm gleaning through the forum, interesting equation wise, what brings forth demise (y) (meaning not total demise) sooner:

a. less kWh (i.e. 40 kWh vs. 62 kWh) so lower capacity uses up more full pack more 'regularly' thus heating more and wearing out the pack.

b. more densely packed (i.e. 62 kWh vs. 40 kWh), less heat dissipation in the higher kWh

c. and of course lack of cooling system, regardless up to this point

So I was checking costs for the 40 kWh battery; and for some weird reason it's selling for the same price that I bought my 62 kWh last month! And I also bought mine from Tennessee. Now I understand probably why that's the case (location), as the batteries are built there.

That's a good point about 40kWh being their future 'low go to battery', so that would mean for the time being (4 + years?) they'll be some fresh ones.

I'll pull up an image of the serial number of my 62 kWh when time provides so that as users we have ever the more data.

Took a 75 mile drive today (sometime quite quick on the 405, 'fast' lane much of the time), again with surf racks (no board on there at moment) and Thule hitch carrier. Had quite a few guestimate miles left (158). I recall with surfboard on Leaf (my other 2011), my mileage was shredded. So the rack will be used for local surf trips at slower speeds.

Aloha!


And I wonder how soon, my total cost for my project

$7500 62KwH battery
$1300 installation

$8800 (U.S.) or €7200 (Euro)

will drop much more!

I honestly don't know how you lucked out finding a 62 kWh pack at that price.

Battery capacity is measured in kWh, not "kw".

Since you've made the same error in multiple posts including after I pointed it out two days ago (https://www.mynissanleaf.com/viewtopic. ... 85#p595985), are you aware of the difference?

There are probably 100 million adults in the US alone who wouldn't know nor understand the difference (nor likely care).

I would venture to guess that my wife and sister, who both drive a LEAF, wouldn't know the difference either. If I bothered to explain it to them, they would either go glassy eyed, or forget a couple of days later anyways.

Why do you let this bother you so much? You're fighting a loosing battle...

Has to be the lamest defense of ignorance I have read in years.

On another note; I question your desire to have a more accurate speedometer (something most cars don't have) over sacrificing odometer accuracy? Cause you can't have both

Typical pompous, brash, abrasive response from you whenever you take issue with someone.

I can't be bothered arguing with you, it's easier to tune you out using the Foe feature, which I've not used in almost 4 years of visiting these forums.

First, why in the world would you stick your sniveling nose into his preference ?
Second, if ideological litmus tests are your thing, then you will love trumper forums.

Yikes. I know it's a pandemic and all that, but maybe we can turn down the nastiness a bit? I'm talking to several people here, not just one.

[cwerdna]

@cwerdna -- Thanks so much for pointing out my error in KW vs. kWh.

That's what were here for, learning. Keep it coming, and can't wait to learn more about your EV journey! Your role as an educator is really important for folks like me who are excited the EV possibilities and are still learning the 'speak.'

Mahalo

Thank you.

To be clear, kW is a unit of power. kWh is a unit of energy.

If you had a 1000 watt device that ran for 1 hour, it consumed 1000 watt-hours (Wh) or 1 kWh.
1 watt device for 1000 hours? 1000 watt-hours -> 1 kWh

Multiply the units while also multiplying the values.

If you could charge a Leaf at 50 kW for 1 hour --> 50 kWh came out of the charger.

50 kWh / 1 h = 50 kW (the h/h cancels out)

In comparison, we've had some people who were confused and even became ummm.. agitated when people where trying to teach/correct him. See viewtopic.php?p=389319#p389319 (has a bunch of incorrect unit usage). He kept making unit errors and decided to make up his own units (mfu) like at viewtopic.php?f=4&t=19890&start=160. Oh well.

Wait a sec, I missed that odo/speed comment.

You can have an accurate odometer AND speed indication. We're doing that right now on a few test cars already. The odometer and dashboard speed indication are completely separate quantities on the CAN bus.

cwerdna,

You need to let this go. We all know what one means even when Kw vs kWh is used. This is a car forum, not a science or English class. We see people miss-using words all the time but we understand. Some examples are Charger instead of ESEV, “there” vs “their”, “your” instead of “you’re” etc.

You would go crazy on some of the truck forums I frequent, where English sometimes seems like a 2nd language.

All of which bother me, and I'm not alone. I agree that Cwerdna can be a bit OCD about this particular mistake, but he also has a point: if we can't get the terms right in a forum where technical issues are being discussed, then the value of the conversations is lessened. If it's a newbie posting then we should cut them some slack. If not then a gentle correction isn't so bad...

If you want to see how bad it can get, visit endlessphere.com. That's an EV site where no one cares about these things, and it often reads like a grade school chatroom.
