Anybody with 2011 or 2012 interested in upgrade to new battery?

[jkenny23]

$13k, $15k, $20k - all that is too much for this car, I want to keep it cheap.

That's why I'm most excited about Mux's system. Theoretically his method can scale to any future battery tech, if there's a new cheaper source of batteries for example. Personally, I'm still hanging on to my 9.8kWH of PHEV batteries. They'll need to be supplemented with another high drain pack, possibly using VTC4 cells as they're one of the most robust 18650s for charging/discharging rate. After I get my "main" extender pack set up, I can keep adding range to it in the future, with less and less stress on each incremental pack of cells (and on the original pack too).

Seems my Leaf should have battery heater as per https://www.cars.com/articles/2012-niss ... 663161727/, but I didn't find any signs of it in Energy Info menu.

I found another image on Ebay - power socket is the same, control socket IDK, but no heater socket:

Thanks all, I know what to do if I only swap cells, but here I'm looking for the way how to swap G2 <-> G1 battery.

Andrey,

Do you already have the battery pack? If you have a 2012 with heated seats, yours does have the battery heater. The battery heater is a 3rd plug on the front of the battery.

The best thing to get would be a wrecked 2012 showing 12 bars. That would be a warranty replacement pack, as 2012's with an original pack would have degraded by now. If you do that, the battery swap tool from Evsenhanced would make it an easy swap: https://evsenhanced.com/products/hv-bat ... ring-tool/

If you already have a pack and it's not that, then buy a pack from 2013+. 2011's are missing the battery heater, so you won't want that. If you go this route, you'll need to make or get an adapter harness from 22->36 pin. I don't know anyone selling those.

You'll want to get the cover panels from underneath the wrecked Leaf. These panels differ from G1 to G2, so you'll need them from the Donor leaf.

Finally, if the Donor leaf isn't a 2011/2012, you'll need the adapter kit sold by Nissan. I don't have the part number but basically it's an adapter bracket that fits to the bottom of the car to accept the new battery mounting.

Or you can swap cells.

Good luck!

Yes, I posted real picture of 2014 battery pack I already purchased: viewtopic.php?p=570877#p570877
If I have a heater already in my Leaf`12 why it doesn't show up in Energy Info menu?

Like in above, 2014 pack is waiting installation. Finding wrecked 2012 with replaced battery is like finding gem. Yes, you told me about the tool, I remember that.

I need to drop my battery first and see. I don't know easy way to peek what connectors are without dropping it.

That's easy part, you can buy all the stuff from retrofitting doc for $200, including covers and brackets.

Or you can swap cells.
Good luck!

Yes this is known way but hard one. And I won't be able to sell old battery which is still 8 bars. Not sure how popular are just modules.

The battery heater only turns on when the pack is very cold, doesn't draw a lot of power, and just keeps it above freezing. It doesn't show in energy info. If you have heated seats and you're in the US, you have it. It's part of the cold weather package.

As I understand it, NZ and UK Leafs don't have it.

I need to drop my battery first and see. I don't know easy way to peek what connectors are without dropping it.

You have 3 connectors, a 22 pin, heater, and the hv connectors. Your 2014 pack has 3 connectors, a 36 pin, heater, and the hv connectors.

That's easy part, you can buy all the stuff from retrofitting doc for $200, including covers and brackets.

Assuming that also includes the 22->36 pin adapter, you're all set! Get the pairing tool, swap packs, use LeafSpy to clear the codes (there will be lots of them), and then use the pairing tool to clear the P3102 code. You will also need the battery disconnect plug--it's different between G1 and G2, and it wasn't present in your picture.

No need to swap cells with your setup. Should be easy peasy, except for the whole "800 pound battery pack" thing.

Let me know if you're in the US and need someone who rents the battery pairing tool. I can provide you his contact info.

For sake no, no CAN(OBD2?) adapter. Will look what wire does what, I've read somewhere it's interconnectable.

Hope so. The battery is 650 pounds. Still heavy but not that much!
I'm in SJ CA, somewhere close to Cor. If everything hooks up I'll PM you, thanks!

$13k USD for a 36 kWh pack. That's quite exciting! I hope you guys get to scale, get prices down even a little bit more, and offer product in the US.

I think you'll find a *ton* of interest in such a pack for ~$10-11k.

Thanks

I'm just contracting design, build & commissioning services to them. Cash to fund the project is the issue. If they can get a decent amount of pre-sales or investment they can get it done sooner and have more success and therefore more cash.

There's a company EV West, they are doing EV retrofit kits for ICE cars from wrecked Teslas around this price (battery, motors, controllers, chargers etc.).
If such spending for a cheap car is OK for you, contact them and I'm sure they will find a way to provide you just the battery and controllers for your Leaf. Imagine half or at least 75kWh battery made of non-degrading 18650 elements powering your Leaf.

PS: Not commercial.

The two plugs (22 and 36 pin) are nissan specific, and you'd need an adapter harness created specially for that. I don't know anyone selling such a thing, but you could potentially make one yourself or contact evsenhanced--they may be able to sell you one. evsenhanced has the plugs on some of the other products they DO sell, such as the canbus translator.

[Andrey]

Asked them, but I can only imagine how much will they charge for that, as they have CAN-EV -> OBD2 harness for $260. I made it myself for the price of OBD2 female port.

They just replied with

The difference between the 2014 and 2012 battery is not only the different 22 and 36 pin connectors but also a different CAN signal from the LBC. We're working on such adapter. Should be available in 6-8 weeks by price of NDZ$495.

I found where they (probably) get 22-pin male connector: http://apps.us.yazaki.com/ComponentCata ... 7283875030, looking for PN of 36-pin female connector. Maybe this one: http://apps.us.yazaki.com/ComponentCata ... 7287106530
