The weak link in the chain of EV adoption right now is what you do with it after 3 years, especially in warmer climates.. Here's how you create a used EV industry.

(1) Read or skim this article. Do the math $200/kwh * 24kwh. Now imagine a $4800 battery replacement for your 2011 Leaf.
(2) Get a handful of electrical engineers and mechanical engineers enthusiastic about EVs to do what Nissan isn't willing to do and the existing Auto Parts/Service industry isn't ready to do. Buy and Sell batteries, and service EVs.
(3) Get some funding and buy a bunch of Old 2011 and 2012 Leafs. The re-sale value is ****, so this should be the easiest part of the equation.
(4) Figure out how to refurbish the old batteries to 100% or 12 bars.
(5) Get technical schematics on all EV models and create documentation and training to create blue collar mechanic jobs. These mechanics will be responsible for battery swaps (maybe with assistance from a machine) and general EV servicing and repair.
(6) Offer refurbished batteries for a reasonable price with the requirement that consumers trade-in their old battery, allowing you to replace the battery you just sold, and lower the price for the consumer. Then refurbish that old battery and rinse and repeat.
(7) Offer a 1 year or 10,000 mile 12 bar guarantee. Then have the option to pay for battery insurance at $20-$50 per bar per month after that.
(8) Make sure each one of your shops is solar powered and off-grid, with battery backup using old leaf batteries. This will allow you to operate in 3rd world countries and outcompete the competition cuz you'll actually have electricity to work. Also, provide charging for EV's at all your stations.
(9) Invest in R&D to create your own after-market battery system to sell to automakers and consumers.
(10) Create a Desert Package version of your designed battery for EV's in hostile climates to use.
(11) Create a charging network based off of solar panels and battery backups using repurposed EV batteries. Think Tesla's Superchargers. Make it free for anyone who buys a battery from you. Paid for everyone else.
(12) Make sure every building you erect and every parking lot is covered in solar panels. This way you can become a sort of utility company in a small way. This way you can sell back electricity to the grid if you wish, or even provide your own grid to communities in underdeveloped countries.

So think of it as a Company that:
- is off grid
- is solar powered
- Services EVs
- Repurposes and Refurbishes old EV batteries
- provides charging infrastructure at a cost to consumers
- Eventually Designs and produces new batteries to sell to various industries (think electronics and automakers)
- Provides Utility services and a smart grid

It's not that complicated. It's just a mix of math, science, and willpower. Create a demand and someone somewhere will fill that demand. Might be me, might be someone else.

I've been tossing around ideas of starting a company that is centered around solar power and battery refurbishment for use in company infrastructure, and creating services and products to sell. I've got enough on my plate for the next 2 years that I could care less whether I actually do this or someone else runs with it, but It's unrealistic for us to expect Nissan or other EV manufacturers to give us everything we want.

The used EV market is going to be huge, because EV's have fewer moving parts and will last much longer than normal ICEs (not the battery of course). There's 60,000 Leafs worldwide that will be out of warranty in 5 years, and 60,000 24 kwh battery packs people are going to want to get rid of. Not even taking into account other EV brands.

Moreover, EV's have one major consumer weakness: The technology is advancing so fast that your EV resale value will be **** after 3-4 years. I've owned my 2012 SL Leaf for 1 year 8 months and just a few days ago a dealer solicited me $21k for it (not that I actually want to sell it to them). Meanwhile I paid $44k for it with all the upgrades and 2 year extended Silver Plan from Nissan. Why buy a used 2011 or 2012 EV with 60 mile range or "about" $100 a month battery lease when you can buy a brand new 2014 or 2015 EV with 200 mile range and improved features. A battery repurposing business could turn that weakness into a strength. Buy an EV and never HAVE to buy a car again. Especially if they could upgrade the range on your old EV. Imagine 2011 Leafs with 300 mile range after-market batteries.

I'm familiar with corporate greed and I can promise you that the dream of car companies (maybe with the exception of Tesla) is for you to lease every car you buy and replace it every year like an iPhone, and the dream of utilities is for you to pay $2 or more per kwh even though today we only pay $0.05-$0.45 per kwh.

EV's will only be economical for the early adopter who invested in solar, until the Auto makers and Utilities find a way to make it all as expensive as ICE's and fossil fuels. Unless someone does something about it. Solar panels and battery repurposing are the way out of corporate greed and price gouging that I foresee.

Total tangent: I leased my fiancee a 2013 Leaf, but I like my 2012 way better. 2013 is stiff, gets less miles/kwh for some reason (might be the new tires have more friction), and is missing electronic parking brake and adjustable headlamps, etc. I plan on keeping my 2012 Leaf for a long time to get the most bang for my EV buck, and make it my little science project. I only did a 2 year lease on the 2013 so I can get her a Tesla Model X when it comes out; I trust Tesla to do EV's right. I don't trust other manufacturers so much. Elon Musk has done exactly what I would have done if I owned an EV car company, right down to the off-grid superchargers. Love that guy!

That's the kicker. If the cells have lost capacity more or less evenly, then I'm not sure how you'd do that. To get to 100%, it seems to me that you'd normally have to replace all of the cells.

But maybe "90%" would be good enough (the GID-indicated capacity of my 2011 LEAF), and could be achieved by cherry-picking the best cells out of the salvaged packs of totaled LEAFs. For that matter, a salvaged pack from a temperate climate might be quite usable as is. Eventually, I could see a company offering pack replacements sourced from salvage.

A replacement pack could be built from the ground up using cells from a different supplier, but that's obviously much more work, and cost.

Something needs to happen eventually. If I need a pack replacement, I'm sure not going to start making perpetual payments to Nissan! :evil:
 
I just had a crazy thought - Elon Musk should totally do this! He has the money, and could totally take out his biggest EV competitor, and give us the 200 mile affordable EV he's been talking about all at the same time! I'm sure he's got time for yet another company.
 
My concern is liability. Who pays to replace the car and the house that burned when an after market battery is determined to be the cause of a fire?

Your home and auto insurance carrier will figure that out after rebuilding your home.

Yes, that would be the idea. The naysayers on this forum say it is never going to happen....given extremes (cost wise) you have to go through to just upgrade the on board charger of the 2011/2012 models I am inclined to believe them.

If there was a viable business model out there to prove them wrong, that would be fantastic.
 
As far as I know - and I'm sure someone who knows better can/will correct me - but as long as you match the voltage range there doesn't seem to be much stopping you from gutting a LEAF pack and filing it with laptop batteries.

Aftermarket remanufactured batteries seem almost a certainty... the only question is cost.
=Smidge=
 
I think its a bit more complicated than that..
Unless you plan to swap out every single cell in the pack, the BMS output etc. all will have to match and work with the Leafs systems...But maybe just exchanging every single cell will work.

Until/unless Tesla changes battery chemistry, the notion that a Tesla-style laptop cell battery could be swapped into a LEAF is not reasonable. The Tesla batteries need a cooling system to keep them from overheating, with potentially catastrophic results. That is one reason why Nissan and GM went with LiMn chemistry: it is safer.

I hope that nobody is suggesting that a cooling system could be retrofitted into the current LEAF; that would be wildly impractical. Someday a new battery chemistry will likely supplant the current Tesla cells, but that figures to be a ways off. In the meantime, aftermarket Tesla packs in a LEAF are not going to happen IMHO.
 
I wasn't suggesting putting Tesla batteries into a Leaf. I'm saying somebody like Elon could start up a side business upgrading battery packs. Whatever form that may take.

I was thinking more towards using chemical processes to actually heal the lithium battery. Like I said, they'd have a ton of batteries to experiment with before launching their business. Read this Wired Article regarding Self Healing batteries

Homeowners Insurance
Car Insurance
Business Insurance

What happens when the repurposed 12 volt battery you buy from autozone burns down your house?

I agree with you, but the point of this article is that viable business models don't materialize out of thin air. People see a problem, and they decide to fix it, brainstorm, and hopefully make money in the process.

The idea is to literally take apart every module and find a way to chemically refurbish it, or if that's too hard, analyze the chemistry and find a way to use the same battery chemistry in a newly manufactured pack, and not violate any patents in the process :)

None of this is even half as hard as what it took to start Tesla. So it's doable.

Unless you have some nano-tech demons that fix the electrodes molecule by molecule, I dont think it is possible to "heal" the battery.

And founding Tesla took a LOT of money.
But replacing the old cells with fresh ones (that match size and form with old ones) should work. Sounds like a lot of manual labor by highly skilled technicians....

Whatever the business model is; replacements or even a service to swap batteries for a Leaf (after some customizations), I think Elon's the guy who could pull it off.

When A Better Place (VC backed battery switching company) went bust, Elon stepped up.

Now, where Nissan messed up, Elon could offer a solution to Leaf owners.

I don't think he will provide replacement batteries (where he can sell you a Tesla brand EV product) but offering a service to swap batteries for Leaf owners could be a potential proposition. Assuming of course, there is a technically feasible way and low cost method to retrofit/customize for the Leaf to accept a swapable battery.

So, who's got his email addr and have the courage to send him a suggestion? ;-P
 
I applaud the case for recycling LEAFs/Batteries in the secondary market. Here here! But with so many "what if's" in play it would also be wise to include a "What if Nissan releases a new higher capacity/low degradation cell that works in the Gen1 LEAF?". To think that the 2011 Gen1 LEAF cells are Nissans final word is likely a mistake.

But yes, third party modifiers will happen quickly when the market demands it.
