The 24kWh battery-pack problem offers several opportunities for your company: 1. Powerwall: get the Nissan battery management system running and attach a battery monitoring system, so people will buy them for their solar systems. 2. Peak-shaving power pack for commercial use. Businesses can lower their electricity bill quite a bit when they can reduce their peak power-usage. So you can combine several battery packs according to individual need. 3. Self-powered trailer: attach a pack to a trailer with a motor on its axle, that can be attached to any vehicle without reducing its range. There may also be demand for powered RV trailers.
Hello there from Belgium, I hope your business grows quickly and that you can make various kit that people could fit them selfs, like a kit to connect solar panels to a 24kwh battery to a 5kwh ac inverter for example. And making an aluminum box for your extender battery instead of wood and lastly a cooling system for those existing leaf battery packs air or liquid. Enjoy your business it's great.regards.
Good luck with Germany :D I had to get few approvals for my vehicles, trailers and even aftermarket alloy wheels for my Nissan Leaf. One word to describe it - MADNESS...
You guys need to focus on what you started, adding extended batteries to the first generation Leafs, create a pack that you can sell all around the world and have local EV shops install them. That’s what we all need and want, just make that happen.
I think, this would be a great idea! Maybe, that's the only way to sell the 24kWh battery packs... @PowerElectronicsBlog How much effort do you think it is to build this? There are AC/DC converters with open-source APIs for batteries, so I think, this should not be the problem. The biggest problem is to implement the communication between converter and battery. But you have a lot of knowledge about the nissan battery protocols. So, maybe this would be a great idea for your next project ;)
@@PTPLSFAN damnit, why does everybody get this idea. I was meaning to keep this a secret until we figured out some more technical details, but yes, we're making a powerwall in the future that you can directly plug a 24kWh pack into.
@@PowerElectronicsBlog Will it be easy to buy in America? May sell my 2011 Leaf once it is no longer useful, but might also want to convert it into a powerwall with Solar Panels and sell the leftovers of the Leaf for a few hundred to a scrapper.
@@PowerElectronicsBlog sorry but I was thinking what I could do with my old battery and came up with this idea... and plan to ask/give you the idea in a next video. If you would like I can send you ideas for products by mail next time...
Hello from the US! Now that you've decided installations in the US are problematic, I'd like to inquire about purchasing a CAN bridge and proceeding with a DIY project. There are quite a few 2011 Leafs available in So Cal for around 4000 euro. I love mine but I'd love it more if the range was increased. Please advise. Wishing you well in your venture!
The amount of metal on the reduction boxes looks totally normal to me, you can find similar amounts on the magnets inside the gearbox of an ICE car. I also expect the oil to only go bad with age or contamination, so probably not an issue yet as these cars are less than 10 years old.
1 -You can contact Rich Rebuilds for US customers ! The guy has the Electrified Garage now , and he's an EV maniac , we love him . 2- Regarding the trunk mold , you can use some cardboard boxes and some polyurethane spray to fill in the gaps and get a mold in no time ! Great job ,by the way ! Keep it up .
He 's last project was a BMW I8 ! I bet he can and he is interested . Just send him an email . There are also the guys from fullychargedshow , they will love to have you on their show in February at their event in US . I've seen you mentioned in some news report , so they do know about you already .
@@johndoe-vm4ps , rich dissed someone for having standard tier model 3 who criticized one of his videos just some videos ago, I dont think touching leafs is something he find worth his mighty effort :P That was sad to see.
There are thousands of early model Leafs, especially 2011 and 2012`s in warm climates at 7 bars or less rendering the vehicles almost useless except for short trips. We desperately need your can bus! Even some type of kit with a circuit board and component list would be sufficient. Jerry in the U.S.
moin, so for the germans its hard to get aproval by tüv? So there is a risk, that it would be removed when the next test is to be done. The next thing would be losing insurance... what does the tüv in holland say to your personal car? please make a conversion time lapse video....
We don't quite know yet, that's really all you have to take away from this. We've had two conflicting bits of communication with TÜV Rheinland, one saying the certification requirements are pretty much identical to the Netherlands, the other stating we need E-cert registration for any parts we put in the car. We've followed up on both but haven't had a response yet.
I'm pretty sure you answered before in another video, but do you plan on adding CCS to a Leaf? It appears to be the growing standard, at least in the US and Europe, who knows how long CHaDeMo will live, plus CCS is going to higher rates also.
Yes he is planing but first he plans to upgrade CHAdeMO since this is easier. CCS uses IP communication as far as I know so you need to translate CAN communications to a different protocol. That is why this will take longer... EDIT: I think IP is Tesla... Anyway it is more work to to translations from one protocol to another...
ChaDeMo 100KW sounds very interesting :) You will use parts from the latest E plus for that? Or will the current socket plus cabling (thickness?) already be good enough for that?
nope, this should work natively on any Leaf, it is only limited by communication. We checked the wire thickness and pins on the chademo plug; it is identical for the e-plus and old Leafs.
@@PowerElectronicsBlog Great. Especially useful on a standard Leaf, so you can heat up the batteries faster :P But it will have a great advantage with an extender battery of yours. Although seeing from your earlier race (which would be even faster with 100kw charging) you will not just be able to endlessly do that.
Hey, I'm really interested in joining the waiting list/getting a battery upgrade on a 2011 leaf with 8/9bar battery. I can't find your email address anywhere to get in touch! Cheers, Sam
Totally different subject.... Do you have the ability to design a direct from solar panel charging system for electric cars, leaf or otherwise, without using any batteries (except the batteries in the car) and without having any input from the grid ?
Maybe slightly hypocritically - we use batteries from such cars, but VW has some of the hardest to reverse engineer CAN bus topology, so we're not going to see e-golf extender batteries anytime soon I think.
I've started to dive into the idea of adding a big solar panel setup to a env-200 having it charge directly to the batteries. It is doable via Solar->Controller->Batteries->Inverter->Car Charge port, but it would have been neater to do it more or less directly from solar to cars batteries. Do you have any info on that?
We're pushing this idea a bit further down the priority list; this is likely going to be a student project in the new school year (Aug-Sep 2020). And yes, this will likely involve a specialized MPPT-equipped DC/DC converter that directly charges the extender battery from a few solar panels on top. If we'd go via the charge port, you incur so many losses (mainly the car's contactors, a pump and some electronics on standby consuming ~120W continuously) that it makes no sense anymore to do this.
We do - we don't have a public order form yet because the waiting list is already quite long, but we're catching up at the start of 2020. You can send us an e-mail at info@muxsan.com to get on the order list.
Wanted to let you know, that there has been now confirmed "conversion" by dealership, for little compensation, from 24kwh to 30kwh and they just simply copied bms firmware from old to new. Gom shows silly stuff but everything else works as it should. No man-in-the-middle needed and it works..
The firmware copying trick technically works, but is quite dangerous as you mess up the battery calibration tables. The 24kWh and 30kWh have very different chemistries, so you can't use 24kWh internal resistance/polarization calibration tables on the 30kWh cells. This will eventually cause damage and/or unnecessarily reduced performance.
@@PowerElectronicsBlog how will the damage occur? Doesn't the bms'ing end up in voltage monitoring anyway and not letting cells going under and over some threshold? Do these voltages differ by your information or get charged too rapidly at a "wrong" state in the curve or.. I thought lipo safe and operating voltages are quite similar.
@@gelisob I think you can get an idea for how the Nissan BMS uses lookup tables by reading my blog on the subject: ssj3gohan.tweakblogs.net/blog/18181/how-to-manage-a-battery
@@PowerElectronicsBlog thanks, i'll go over it. Just bought myself a 2013 leaf with 330k on the clock, original battery. With plans to swap next year for a bigger newer one. One reason i started following your work but you are a in the other end of europe, kind of :) This is why i was happy to hear that there's also an easy way..
@@PowerElectronicsBlog I red your post but i'm not sure how you figure the difference in resistance calibration tables will damage the cells. Do you believe BMS is made more complex than necessary? Do you believe monitoring the total IR, voltages and temperature for charge-discharge decisions not enough? Why would manufacturer tie it's bms to some non-flexible table values for a product that diminishes over time, instead of just reading the current IR and acting accordingly? Have you seen occurrences of bms firmware transfer to larger battery resulting in extra wear-damage to the target battery? I also had an issue with the "The strong stay stronger, the weak become weaker." part of the article, In my experience with ebikes, for cells in series, if they are not completely failing, the weaker give out less while stronger compensate the weaker, same when charging, the other way around, balancing out in the top and bottom quite well :) As there is so much series-parallel action going on - it would take quite many cells going very bad for noticeable affect on the overall performance imho..
I really love watching yours videos 👍 great job, well done!! I'm waiting for" man in the midle" to be available to buy and swap 40 kwh into my 2012 leaf. What is resonible price for 40 kwh battery from junk yard.
we pay 6000 euros ex. VAT for a verified working and good condition battery. You can get them for between 4000-6000 euros depending on state, we haven't seen them cheaper yet.
Hi, great channel, have been watching it for over an year now, keep it up. I have an 2011/2012 leaf and I have a 40kWh leaf battery from a 2018 leaf which I got at the local scrapyard. I really want to do an upgrade and I would probably sign up for an upgrade with you if I lived somewhere in mainland Europe. But since I live in Iceland that is not really an option. So, in you video you mention that you have been selling and sending out "kits" to people in faraway countries. I would very much be interested in that. I have owned 3x leafs which I have been fixing and selling, so I am very familiar with the car. I also have a fully equipped workshop, so I am capable to doing all the work needed. Liability wise, I would of course take full responsibility in the conversion and the "kit". I would appreciate if you could reach out to me.

I see you are ready to licence your products to others. I might be interested in this. But after my upgrade gets done and I see a process...
