After costing up 20KWH of 18650 lithium Ion batteries at around NZ$11K delivered I have decided instead to try and purchase a nissan leaf at a salvage auction this thursday. I had a go last week for an early gen2 model but did not really research what I was doing and so chickened out at $6K and it sold for under $7K

Now thinking about it, the leaf also has the charger, inverter, engine, bms, connectors, heaters, HVAC, pedals etc I can also use and so this $7K now seems cheap in retrospect.

The model on thursday is a 2015 gen2 model one with 33,000KM on the clock, there is nothing in the description to help me. It has frontal damage and the air bags have gone off, the damage to the front does not seem to have got past the radiator and the engine looks OK, there is no rear or side damage I can see so my main worry is the batteries whether the damage has affected them. It also has a low battery warning showing so the two red flags for lithium batteries are impact and cell voltage too low are both present or is the leaf pretty tough?

I do not plan to attend the auction as it is 3 hours drive away but I can bid on-line, there is a 10% buyers fee and another $500 to transport it home so I was going to bid upto $9K

I worry a little as there are lots of gen 1 2011/2012 leafs with 7-9 bars going for about the same final price as I intend to bid but I hear the gen 2 batteries are better and I dont want to take a good one off the road it just seems wrong :confused:




All advice welcome

Hi
Decide on a max and go with it! - don't forget you may be able to sell some other bits that you don't need

Sound advice. I am definitely one to get carried away so I need to reign myself in, just got to remember I can always buy an older undamaged one if this one slips away..

Any advice form anyone on the robustness of the battery would make me feel a lot easier though.

PS I tried to link the pictures but the system ignored them probably because the image link did not start with the normal http string, auction link is here

A word of warning, from personal experience. Don't expect to sell much of anything off a salvage Leaf, except things like hubcaps, wipers, maybe floor mats - piddly stuff like that.

I did the same type of thing (buy a salvage leaf for the battery and sell off the rest).

Don't worry, the battery is very well protected by the vehicle.



You can read all of my blog posts about the process, how I disassembled the battery, etc on my blog.


The "leaf" tag will get you all the posts

https://www.summet.com/blog/tag/leaf/


(in reverse chronological order, so you probably want to go to the first one and start there...)


You probably don't need to read the "How to buy a salvage leaf" one

https://www.summet.com/blog/2015/03/26/how-to-purchase-a-leaf-battery-pack-and-surrounding-car/


But the next few may be useful:

https://www.summet.com/blog/2015/04/04/how-to-drop-a-nissan-leaf-battery-pack-without-an-auto-lift/


https://www.summet.com/blog/2015/04...san-leaf-battery-pack-and-remove-the-modules/


After that there are a lot of posts about how I used the modules to power my Chevy S-10 conversion.


The last article that may be of interest is my final cost calculations

https://www.summet.com/blog/2015/11/21/economies-of-harvesting-nissan-leaf-battery-modules/


(I WAS able to sell a lot of parts from my Leaf and recouped almost 75% of my auction cost, but it took me about 9 months to do so.)

Hi Jay

Thanks for the information and the links which should really help. I have already recouped 15% of the costs as the auctioneer included a local GST Tax on the total which I can claim back as I am a registered electronics business and my plan is to add EV consultancy to its services once everything is working.

The car gets here Wednesday next week and I will probably strip everything useful out over the course of the month using your handy blog post to help, I will be keeping just about everything except the shell and trim which I will list as a job lot on the local auction site for $1 reserve + buyer collects otherwise the wife will start to seriously get pissed off having another car in the drive for any length of time. Both airbags went off in mine but it is only the front LHS which took the hit so a lot of the trim should be salvageable.

It is a real shame I already purchased a 25KW/55KW AC motor as the Leaf Motor looks nice and Paul Holmes posted some videos of it working with his open source Controller which I am currently assembling.

I do however need to keep the current battery voltage configuration as my motor and controller work at 320V, the layout will need to be modified extensively to fit in the E39 Shell. I would also really like to keep and if possible get the battery working with its charger and BMS.

I also noted Thunderstruck Motors have a replacement VCU which would allow me to easily re-use the motor and inverter, though unfortunately it does mention anything about which version of the leaf nor if it also spoofs the battery management and charging.

I will get some video and pictures of the process over the course of the next month and post them here.

Interesting times as they say..
