Now that is great luck! Sounds like you will rarely have to pull from the net eh?

And you even kept it out of a landfill or whereever they were going to "throw it away" to..

I currently drive an Nissan Leaf, and I am also very interested in Solar systems.
So I started thinking an battery from Nissan Leaf would make a good storage for solar power I normally export to the grid.

So, I got a hold of a battery pack from an wrecked Leaf, and started building.
First of all i had to make it about 48V, and to do that i have to put 14 Cells in series.
Each module has two cells, so its only 7 modules in series and 6 in paralell.
Then I can use 42 of the 48 modules from the battery pack.
This may be expanded with more modules later, we will see.
These batteries are all from one battery pack? 18kwh, that must be. WOW!

Yes, but now I am using almost 1,5 battery pack, total of 70 modules.

Do you have any plan for how to maintain the cells that are not in use? If you can continue to find these used packs for sale so cheap, you could package them in a rack as you have already done and sell it to others for a worthwhile profit. It could even make a good side business.

The cell that are left over are already sold, with a nice profit.
Actually, the local dealer have one more crashed car coming in next week.
He has my number, so we may make another deal. But i think the price will be higher this time ;)

Ok - what's with all the crashed Leafs in your area? Folks drive crazy or something? Do they come equipped with targets on the backs?

Wish you were in my area, I'd give serious thought to hiring you at least to consult with building a system like that here...

Actually, Nissan Leaf is one of the most sold car in Norway at the moment and its been very popular from when it came in 2011.
We are soon passing 50 000 electric cars, and most of them are Nissan Leaf. Tesla nr 2.
Some of them are bound to crash, like any other car i guess ;)

Here they have removed ALL taxes from electric cars, and gasoline cars have crazy high taxes.
Even the middle-class working guy can afford an Tesla.

The thing is, most Leaf`s still have warranty on the battery so there is no after marked for the batteries.
And the scrap dealers have to pay to get rid of it.

I have been posting this on some Norwegian forums, and I know that a few more are now considering doing something similar. Just hope i don't hear about someone getting hurt.. 360V DC will do more than just give you a tingle..
