I now have some capacity numbers to share, and time to make a decision.
Test, 5Amp discharge, from 4.1V -> 3.3V
USA cell: 39,77Ah
Italy cell: 43,30Ah

So presuming I have an USA cell from the same batch, If I upgrade to the Italy cell, I'd get a 9% range increase! I could also try looking for better cells, but most people just sell untested cells :/ Hmm...
Well that is truly a bummer..

There aren't that many wreckers around in Finland either, where you could go and test them yourself. You seem like a handy guy so make do and fit both of them :P

Really nice going through the troubleshooting. I have no clue about the procedures for these cars so this is definitely educational. Keep your head high!

Status update on the Leaf!

I assembled the OpenEVSE unit. Now I need to decide where I mount it. I will most likely make it open to the public on all charging apps, since it probably goes in the middle of nowhere :D
Image

We have also had a fair bit of snow in Vaasa :D
Image

Due to the shitty weather, I decided to get some proper snowtires instead of the all-season ones that came with the car.

I settled on "Nokian Hakkapeliitta R3"
in the format: 205/55 R 16 94 R XL
Image

This is the tyre that Nokian primarily recommends for electric cars, since it's a low rolling resistance and wont impact the range. On the sticker they are branded as B on the economy gauge. The efficiency step between A - B - C goes something like 100% - 97% - 90%, so there is a huge benefit from stepping up from C to B. From B to A the 3% efficiency step is not as noticeable.

I'm in the local paper!

Image

I'm currently in the process of starting up my own company, aiming to be the first in Finland to offer 3rd party EV battery service/swap/upgrades. It's gonna be a wild ride! :)

I went and added the garage to the Plugshare map, in-case someone is close to getting stranded in the middle of the Kvarken world-heritage archipelago :D

It sure is an EV dead-zone out here :D

So, now that the weather is getting warmer, it is way more inviting to work on the car. First order of business, getting the undercoating tiptop.

This is what the stock rear wheel-well looks like
Image

Not very protective at all, when you run on gravel roads, the noise is awful when it slings small pebbles straight on the metal inner arch. So, I de-greased it, brushed it, rinsed it, let it dry, and applied some rust coating with a brush. It also doubles as sound deadener!
Image

One done, three more to go :D

Oh, and for my EV Repair company, I bought this essential tool, the 'EVs Enhanced HV Battery Paring Tool'
Image

Now I can swap batteries properly between cars :)

And if anyone is interested in following my FB page for my business (mods please remove if inappropriate ;) ) https://www.facebook.com/DalasEVrepair/

My end goal is to be able to sell battery upgrades, something Nissan has decided that older cars won't get at all!

Another Sunday, now both rear wheelwells are protected against the elements.

Soo, the Leaf developed a leak... quite a big one too! Not so fun to see it drip from the side airbag :D
Image

Tore the interior apart to investigate, it leaks on the top part
Image

Spread the rubber gasket with zipties, blowdried it
Image

Applied lots of clear silicone, let's see if it holds. If not, the windscreen needs to be resealed. Fingers crossed for an easy fix :)
Image

Started working on the looks. The front of this car is really "froggy". Eyelids should help the look quite significantly. Started by removing the rear piece, not used for anything.
Image

Wrapped the rear piece. Still need to wrap a slight amount on the upper headlight too, but let's see how the material hold up. It had a slight purple color, would have liked matt black more. Ohwell, I will iterate as I go
Image

Then I focused my attention to something more fun. The horn! On all the Leafs, the horn is pathetic. It sounds like a toy car. Lets fix that!

Started by removing the front splash shield, peeking up on the horn assembly from under the car
Image

Here is the stock Denso unit, compared to a 1991 Nissan NX horn setup. I really like 90s Nissans, so it felt like a perfect choice. The same horn setup is found in the S13 afaik!
Image

Horns mounted. The horns ground via the mounting bolt, so had to fashion a wiring adapter. Note the one pin that's not needed anymore.
Image

Here's a comparison

The Man-in-the-middle attack CAN prototype boards from Muxsan arrived today. This thread is going to get quite technical soon...

Now something completely different.

My friend Johan was bitten by the 3d-printing bug, and I am so intrigued! I searched thingiverse for a J1772 holder, and found this simple design:
https://www.thingiverse.com/thing:2481870

So I sent him a message, and little over an hour later, a prototype was printed.

Started
Image

Finished
Image

I was told this was a really fast prototype (Layer-height was 0.3mm), and if I wanted a better looking one it would take roughly 4.5h to print one. I am so excited by such a small piece of plastic :D Thanks Johan :)
