Hi

[@matthewgallagher4913]

Very, very well done. If you make these widely available you can essentially count the number of 24kwh leafs for your total market. I'd love to buy the set to do this on my leaf here in the UK.

[@sergeidorokhin5619]

This battery is OK for 50-60 km daily commutes given that the owner will charge it between 20 and 80%, and would be able to make 100km if needed. My battery looks pretty much the same, and my wife is happy to use Leaf every single day for her work commutes (around 30km) charging it every night to 80%. Anyways, glad to see that you have a successful business helping EV owners to extend the lives of their cherished cars. Hope, at the time I will need to swap our battery, you will have an easy option for the Aucklanders.

[@EVsEnhanced]

Hi. Our products are available for sale to allow any good mechanic anywhere to complete these upgrades. There are already several workshops in Auckland offering Leaf battery upgrades using our battery translators and pairing tool.

[@xhobv02]

How do you set the charge to 80%? Nissan has removed the setting and it now charges to 100% which degrades the battery in my leaf much faster...

[@m.necatisepetcioglu4391]

@@xhobv02 I noticed on my 2016 leaf , i cannot charge up to 80%. But my nissan leaf 2012 i was able to. i have to admit that , they both look the same but i miss my 2012 leaf. that car was definitely not the car for his era. way advance and much more reliable than any other leafs.

Cool video. Just wanted to add the tip that when I looked at replacing my battery I came across Fenix, a company doing battery replacements that cuts you over to battery as a service, with a battery pack with cells that they swap out for good cells so you are always working with a good battery/charge. You can lease their battery as a service, or buy it. May be a good option for some. Cheers.

[@PlugLifeTelevision]

Great video, thanks for taking the time to put it together! From my experience of 24 kWh and 30 kWh LEAFs, the 30 kWh model seems to be more willing to take on a higher charging current when rapid charging, so it charges faster than the 24 kWh model. Since you've retrofitted a 30 kWh pack to a 24 kWh LEAF, have you tried it out on a rapid charger to see if it accepts a higher charging current than before? If so, is it comparable with the charging current accepted by 30 kWh models, or is the charging power more akin to the circa 35 kW peak that 24 kWh LEAFs tend to experience, even with the 30 kWh pack fitted?

One day likely. Not practical in the near future though. If you do long trips occasionally then your car has plenty of range and you just need to find a nice spot on your journey with a fast charger. If you realistically do really long trips like this really often then buy a Tesla with the long range option.

Hi Derek. Thanks for the encouragement. We trade in the customer's old low SoH battery pack. The modules are then removed and used for stationary storage applications as you say.

Excellent work! This is groundbreaking. As you fit a s2 battery to a s1 vehicle, I suspect changing a 24kwh s2 battery for a 30kwh s2 battery will be easier without need for the mechanical changes? Also, would you consider it being doable to fit a new body 40 or 62kwh battery in a s2 vehicle? As far as I can understand, dimensions are fairly similar and voltages are the same.

We have had a translator for the 30kWh battery into a 2013-2015 24kWh Leaf available for some time. evsenhanced.com/product/hv-battery-translator-30-2-aze0e/ Externally, the 40kWh battery is physically the same as a 30kWh battery - only the CAN bus translation is different. We are working on the 40kWh battery translation now. The 62kWh battery is physically different to all earlier packs and is taller and has modified mounting points so isn't such an easy swap. But with some modifications to the car or a custom mounting kit it can be made to fit an earlier Leaf.

@EVs Enhanced My concern would be the weight increase and having to haul that extra weight around with an 80kW motor. The 40 and 62kWh LEAFs have more powerful motors to compensate and some. Do you happen to know what the differences in weights between the 24, 30, 40 and 62 kWh batteries are?

Quick question I noticed that the leaf has only 53K. I am wondering why the owner didn't get the replace the battery under warranty. Thank you

[@EVsEnhanced]

Hi. Firstly, all 24kWh Leafs only had a 5 year warranty and these were built from 2010-2016. Therefore, very few of these will still be under warranty now. It is worth mentioning that Nissan extended their warranty to 8 years with the introduction of the 30kWh battery and beyond. Secondly, here in New Zealand most of our Leafs are used imports from Japan. Even on a newer car, Nissan NZ doesn't support the warranty that the cars would still have if they were in Japan. Hence we have been forced to find solutions to problems far before other people in other parts of the world.

[@edvoon]

Right now of course the first Leaf EVs are coming up for mainly battery replacements. However with fewer moving parts Nissan Leafs could conceivably be running for decades or more, far longer than ICE cars which usually become too expensive to repair due to engine or gearbox issues. How feasible would it be to keep an old Leaf running by replacing engines, computers, etc? Would that be something that can only be done by Nissan (if they even bother to) or will 3rd-party mechanics like you guys be able to find parts and get the technical knowledge to do so?

[@EVsEnhanced]

The Leaf is relatively simple and easy to work on. Like any car, other parts can sometimes fail but independent 3rd party specialists keeping these cars running for a long time is very feasible providing the battery supply/cost issues are resolved.

[@jozefdkois]

Hi EVs Enhanced.I have a 2014 Leaf. Do you know whether the contacts on the on the battery side of the PTC heater socket are live when the heater cable is disconnected? Is there anything inside the battery pack related to the cabin heating? (A fuse or relay? Anything) Thanks Jozef

[@EVsEnhanced]

Hi. The HV relays inside the battery pack shouldn't ever close with the PTC connector removed as the interlock signal circuit on the connector will be detected as open. Yes the PTC has its own small fuse inside the battery pack.

[@jozefdkois]

@@EVsEnhanced , Thanks for your reply, you seem to have an excellent understanding of the matter. I have this situation: the cabin PTC heater is not working. B2772 comes up when I connect to OBD2. I have replaced the PTC heater for a second hand one but it still doesn't work, B2772 is still there. To do more testing, I have unplugged the PTC wiring harness from the battery, inserted a link to the interlock (pins 44 and 45, without it the car would not even go into Drive or Reverse), turned on the heating and checked the voltage between +40 and -41 and got 0 Volts, then I checked between +40 and ground and got around 200 Volts initially, but the reading started dropping (discharging through the voltmeter) fast. I think there must be something wrong in the battery pack, but I am struggling to get detailed information about it. I took the car to my local Nissan garage, was told the PDM needs replacing, I don't think it has anything to do with it, after raising my concerns with them they weren't too sure either. Could you please advise about the components (fuse Amps, dimensions, type) inside the battery pack between the PTC heater plug and SYSTEM MAIN RELAYS? Thanks again, Jozef

[@EVsEnhanced]

@@jozefdkois On the earlier 2011/2012 Leaf we've seen several cases where the PTC heater fails and blows its fuse which is in the DC/DC junction box. On a 2013+ Leaf, this fuse has been moved to inside the battery pack. On these, the PTC heater connector should have a live 250-400VDC applied to it whenever the two main relays are closed assuming the fuse is not blown. It is a 30A 500V old school looking glass cylindrical fuse but with welded eyelets on either end for screws to go through.

Awesome

[@EVsEnhanced]

Thanks.

[@ricardomota3347]

AWESOME JOB !!! Do you have the kit to convert from 24kwh to 40kwh ?

[@EVsEnhanced]

Hi. Not yet. We have only recently found a 40kWh pack to use for development, but development is going quite well so far.

[@andyboyd720]

Great video, and fantastic to see how EV cars and batteries can continue their life. What is approx cost of this upgrade for say a gen 2 24G to a 30 or even 40 battery??

[@EVsEnhanced]

Hi. If you go to evsenhanced.com/services/hv-battery-swaps-and-upgrades/ then you'll find a calculator at the bottom of the page which is the basis for the prices we charge in our Christchurch New Zealand based service center. However, it should be noted that here in NZ we tend to pay more for good used battery packs than in a lot of other places like North America and Europe.

[@dr.projectx5142]

Can this be done to a 2013 leaf and use the 60kwhr battery pack from a wrecked leaf??

[@EVsEnhanced]

Hi. The 62kWh Leaf battery doesn't bolt straight into an earlier Leaf as the mounting points are different. But with some fabrication of a custom mounting kit it can be done. Also the 62kWh pack is significantly heavier than the earlier packs so upgraded springs etc are worth consideration. 40kWh into a 2013 is a straight bolt in job like in this video though.

[@dr.projectx5142]

@@EVsEnhanced that's good to know is there any other hardware needed for the dash to register the new battery pack. I still had the idea of making modules of the new 2170s or the 18650s to have more capacity or the LG chem pouch cells. And I would beef up the suspension for the 7 year old car 2013 leaf. Espacially with the benefit of the chademo port. Would like it to for it to achieve 350 to 420 miles on a charge would be great. Or have it hold 60 to a 90kwhr battery pack and just use it for traveling. It only has 85k miles on it. A d the chademo works great. Just holds 10kwhrs at the moment. With it's original battery pack 7 years old.

[@EVsEnhanced]

@@dr.projectx5142 Our battery translator as shown in the video is what allows a latter battery pack to function correctly with an earlier car. We currently only support genuine Nissan battery packs. Using aftermarket cells with any original Nissan LBC (BMS) has associated problems that have not yet been solved. Essentially the LBC needs a custom firmware update developed to suit whatever aftermarket cells are used before it can function properly.

[@markplain2555]

I have a 2014 LEAF with 98,000kms on the clock and full battery health (according to the car's display). Can I get some advice: 1. How much further until I lose a bar? 2. How much should I pay for a replacement battery (used from wrecked LEAF or otherwise) 3. How much for your conversion kit? In essence, I'm trying to get an idea of the costs I am facing to upgrade my car and how I should start preparing for it, ie: should I start looking for a deal on a used battery now?

[@markplain2555]

Further to the above - I'm sitting in Canada. Do you guys have any relationship with an organization in Canada?

[@steptoe5519]

Mark Plain get the LeafSpy app and OBD dongle to determine state of health (SoH). 1st bar is lost at 85%

[@johnnystacks5179]

What was the original battery pack before the swap? 24kwh?

[@EVsEnhanced]

Yes. Before this swap the car had the original 2011-2012 type 24kWh battery pack.

[@johnnystacks5179]

Can you put a 40kwh instead of the 30kw?

[@EVsEnhanced]

@@johnnystacks5179 Yes. However in addition to the translator, we also update the VCM firmware for this conversion to eliminate compromises.

[@johnnystacks5179]

Can you add a 64kwh

[@EVsEnhanced]

@@johnnystacks5179 Assuming you mean the 62kWh, this does not mount the same way so unlike the 30 and 40 it does not physically bolt straight into the car. However, with custom mounting brackets it can be done.

[@jeromebrown1820]

Dear Friends, what would an upgrade like this cost in Euro’s approximately !

[@EVsEnhanced]

Hi. We have a calculation at the bottom our this page in NZD. evsenhanced.com/services/hv-battery-swaps-and-upgrades/ This is based on a drive-in, drive-out service at our own workshop in New Zealand though. Replacement battery prices tend to be cheaper in Europe.

[@JonJoshChua]

Is it possible to install a newer 62kWh battery in a 2012 Leaf with your technologies?

[@EVsEnhanced]

Hi. Unlike the 24/30/40, a 62kWh battery pack isn't a bolt in job. It has different mounting points and is significantly heavier. So there are other things to do as part of the conversion, but it is certainly possible. We're looking at OBC upgrade options for the 2011/2012 cars as well. Unlike the later Leafs, there was no factory option of a 6.6kW OBC.

[@JonJoshChua]

@@EVsEnhanced I hope you set up shop in California.

[@EVsEnhanced]

@@JonJoshChua We have no plans to do this, but would be happy to supply our tools and equipment to another EV specialist company in California.

[@jeremylister89]

Do you think in the future with battery improvements, a 60kwh battery pack upgrade will be available to early leafs?

[@EVsEnhanced]

Yes. We have already put a 62kWh battery into an early Leaf. In our own country we are working through certification requirements to make this road legal mostly relating to the additional weight. The 40kWh Leaf battery is an easier upgrade for the earlier cars as the weight is very similar to the original and the mounting brackets are the same. With the extra weight of the 62kWh pack, Nissan added a lot more mounting points which are in a different position.

[@HerminiePA]

Can a person get a simple replacement (no upgrade) of a 24 Kwh for a 2011 Leaf? Is it possible in the USA?

[@EVsEnhanced]

Yes. For a like-for-like battery direct replacement, no translator is required. You can just use our battery pairing tool. kzbin.info/www/bejne/gXjJcnaqqMmnis0 evsenhanced.com/product/hv-battery-pairing-tool-individual-use/

[@EVsEnhanced]

Hi. What year/model is your Leaf?

[@edcochran714]

@@EVsEnhanced 2013

[@EVsEnhanced]

@@edcochran714 Yes that combination has been well tested now. However, the 62kWh battery is not a direct bolt in job like a 24/30/40 and it is considerably heavier. It requires a custom mounting kit among other things. Shipping this mounting kit is expensive, so we'll probably pass on the design we use to some of our North American partners for them to have fabricated locally. Perhaps get in touch with Precision Auto just over your boarder in Langley City, BC to discuss.

[@williamrbuchanan4153]

Seems they all have this volume control to put you off listening, should have on screen details ,with sound turned down. Maybe it can be done?

[@EVsEnhanced]

This definitely was not intentional to put anyone off listening. Just an honest editing mistake which we are now more aware of for future videos.

[@leocunningham2945]

Many thanks for the great video - one quick question, i have a 2014 acenta model(UK) that still has the settings to charge to 80% (discontinued in later models), does swapping to 30 kwh still keep this software function ? Once again many thanks

[@EVsEnhanced]

Hi. Yes, if the car had the 80% option then with our translator this functionality will be retained when swapping to a 30kWh or 40kWh battery.

[@shauncross6049]

Looks great any idea on final prices for ZE0 to 30 / 40 or even 62 KWh options I am assuming maybe $500 or $600 plus the cost of the battery. Does it bring back the faster charging allowed by newer packs ?

[@EVsEnhanced]

Hi. Pricing still being refined for the different options, but in NZ dollars the various translators will be close to your expectations. Yes, fast charging speed will be much improved with a newer/healthier pack.

[@sujankuruppuarachchi6066]

[@GEAUXFRUGAL]

Love it was concerned about Battery replacement I see you can get a 30 in a former 24 . I wonder if the 2020 battery would fit a 2013 ?

[@EVsEnhanced]

Hi. 24, 30 and 40kWh are all physically the same form factor and will bolt straight in with the appropriate CAN translator. 62kWh is slightly different physically, although with a custom mounting kit it can be made to fit. The 62kWh battery is also significantly heavier though whereas the 24, 30 and 40 are very similar weight.

[@chandikahl]

Great to hear that 40kW battery is compatible with old leaf. Does the CAN translator module available from EVs Enhanced to be bought online?

[@Afrocanuk]

What's the weight of that battery pack?

[@EVsEnhanced]

The 24kWh, 30kWh and 40kWh Leaf packs are all very close to the same weight of 300kg. It is only the 62kWh pack that is significantly heavier at 440kg.

[@RodrigoOliveira-pj9xj]

Do you have a mechanic specialized in Hamilton?

[@mattw9764]

Ok. My Leaf is at 69% SOH and it does my (two-way) commute twice over with ease. I think, when I first got it nearly four years ago with 85% SOH, it would do three such commutes, just. What's my point? Unless the battery SOH collapses completely (which I have not heard is happening even for 2011 Leafs), there are people out there who can happily use these cars and continue using them for years.

[@evelynpetersen3779]

How much does something like this cost to get done?

[@EVsEnhanced]

Hi. The cost of the replacement battery pack is by far the biggest expense and that varies depending on which part of the world you are in. For example, here in New Zealand we have to pay significantly more for good replacement packs than in North America and Europe. We do supply our products (without the battery pack) to help EV specialists in other parts of the world to offer the same service though. To give you an indication on the prices we charge for a drive-in drive-out service in our own service center, check out the calculator at the bottom of this page evsenhanced.com/services/hv-battery-swaps-and-upgrades/

[@InnovativeSustainableSolutions]

I'm suffering some Leaf range envy after watching this. Very clean work! I know you guys are probably still working out the specifics, but do you have a ballpark idea of what you would charge for this conversion? Where do you plan to source new 30 kwh batteries from? Keep it up! It is so wasteful to send these Gen1 Leafs to the scrapyard after 50k miles, just because the battery is degraded.

[@EVsEnhanced]

Hi. Currently all of our replacement battery packs come from vehicles that have been lightly damaged. In our New Zealand based workshop we would charge approx NZ$10k (approx US$6k) for this conversion drive-in, drive-out when we keep the cars original battery. That being said, we tend to pay more for good replacement battery packs down here than what you would expect to pay in parts of the US, Canada or Europe. Our translator hardware is a pretty small part of the cost - the majority is in the replacement pack itself.

[@InnovativeSustainableSolutions]

@@EVsEnhanced Thats a very competitive price. Very fair. I worry about pack supply as new Leaf sales continue to (unfortunately) decline. I'll definitely be a customer of yours when I get around to tackling a "Leaf Battery Refurbish Project" build. Thanks for the response.

[@EVsEnhanced]

@@InnovativeSustainableSolutions We agree. Used packs will only get us so far due to supply limitations, but it is a step in the right direction. We are going to need new replacement packs to be available for purchase. As you mention, new Leaf sales are declining which means Nissan should have surplus supply of new 40kWh packs available. The current US retail of a 40kWh pack is US$11k + US$1k if you don't return your original battery. That isn't too unreasonable in our opinion - the problem is getting them to sell them. If Nissan doesn't get involved soon they will miss out due to the aftermarket alternatives coming. Some of those are exciting - others are scary.

[@MrNagafen]

Very impressive
