Purchasing A Nissan LEAF Battery From A Junk Yard – Video

MAR 26 2015 BY ELECTRICCARSTV 26

Ever wonder whether or not you can buy an electric car battery at a junk/salvage yard? Well, turns out you can.

Here’s video proof:

“I hit to road to purchase an entire LEAF battery out of a crashed Nissan from a salvage yard. I plan to use the cell modules to upgrade my Vectrix and build other electric motorcycles. But first, I have to buy the pack and get it home.”

Good idea.

This is 100% recycling as advertized 🙂

For the sake of all EVs I hope no one ends up as a bag of chulk playing with these things.
They pack a hell of a punch

You would have to pay a lot of money for a battery that size for home energy storage for a Solar array.

Depends on the storage, the array, and the home. I have enough capacity to keep a few key LEDs on, and keep a phone and laptop charged. Not enough for the fridges or HVAC. But in exchange, I spent pocket money.

Are you the guy in the video? 20kwhr, or even 12kwhr is will keep most places fully powered for 4 hours to a whole day. If you have some solar. These things go together.

12 – 14kWh will power an average house for a day, but not if you want to charge an electric car as well. And as a solar PV and e-car owner, I can assure you that there are long, looooong stretches when the sun don’t shine. Even with a 20kWh or larger battery in your house system you would still need to be grid intertied, at least for the time being.

I’m curious what year model it was from and how much was paid for it at the junk yard?

looks like he only held up 5 or 6 hundred bucks.

I recounted, looks like 1000.

Wow, for hobbyists this is an amazing bargain.

That’s 42$/kwh. Shoot you can’t even buy lead acid for that much.

it s more like $2000 if you putit on pause.
it sill cheap!

Yep second life EV batteries are brilliant and one of the main reasons that promoting the EV revolution is worthwhile for governments. Big batteries available cheaply change everything about energy, its availablity and usage.

My neighbor plans to use a salvaged Volt pack when his lead acid PV backup battery dies.

I use (dead) conventional lead-acid batteries, which do not have enough current to start ICE’s anymore in conbination with a 100W solar panel and cheap (<8€) charge regulators to light up app. 60% of my house with 12V LED-strips or 12V MR16 LED-lamps. Exept for december that works out really good here (Germany)

In total I spent approx. 150€ for that system (which is more a hobby project) Easy to set up, due to high availibility of 12V-components like ir-detector, LED and "second life" lead-acid batteries…

Great to see li-ion batteries getting a second life.

But do-it-yourself-ers should be warned that using li-ion batteries for home energy storage requires a BMS (Battery Management System), something not required by deep-cycle lead-acid batteries.

There’s an interesting thread on the Tesla Motors Club website, showing someone disassembling a Tesla Model S pack from a wreck. He has a lot to say about his attempts to hack the Tesla BMS for use in his home energy storage system.

Why do you need a BMS?

Well, I’m not an engineer, so I don’t know that I have sufficient understanding to explain this clearly. Unfortunately, I can’t find a clear and concise explanation online, either.

But my understanding is that the main purpose is to keep the cells in the pack from getting out of balance. Out of balance cells will age (lose capacity) prematurely, and are in much greater danger of runaway overheating leading to a fire. Furthermore, if I understand it correctly, the limit to charging and discharging of the entire pack is limited by the highest or lowest charge of any single cell. Charging stops when just one cell in the pack reaches its charge limit, and discharging stops when just one cell is exhausted. So, as cells get more out of balance over time, less of the entire pack’s capacity is available for use.

I hope that’s all correct, and I invite anyone who knows more to comment.

To prevent burning batteries due to overload perhaps.

Lucky he didn’t get pulled over by the cops with that amount of cash! Could have been another case of civil forfeiture.

Hmmm.. that battery pack sure fits nicely in the back of that truck.

Just sayin… 🙂

If only the top folk at MB and BMW had your vision.

Wow, so nice of insideevs.com to rip off the guys content without even providing a link to his website:

Paul,

It is a YouTube video, that is the source. It is highly irregular to also suss out the affliated website as well as they are the same source (at any media site on the net). However, we actually did give a shout-out to Ben’s site 300mpg.org (and encouraged people to check it out) on the follow-up video/story…which we posted right after this one.

would be sweet to get a battery from a newer low mileage Leaf and replace the one in my 2011 Leaf. would save me from buying a Volt.
