It is only 95kgs heavier than the original, which just as taking an adult in your car. So no need to upgrade the suspension.

@@VIVNEHelenMao thank you. Will the pack sit lower to the ground than the original pack due to the increased height?

@@decimal1815 The 68kWh battery pack is 25mm higher than the original. Size is the same as 62kWh. So it will be 25mm sit lower to the ground. But it is still higher than the car back rod. For more details, you can refer to this other video on our channel: th-cam.com/video/snwfUmmuWFg/w-d-xo.html

We only use brand new A grade CATL cells.

Don't support can-bridge for 62KWH installing. With can bridge + original BMS can only display 40KWH mileage on dashboard.

@@VIVNEHelenMao my car is 2017 model with 30kWh capacity want to swap/upgrade for 62kWh . so we dont need can-bridge upgrade?

@@aravindia Yes, no need for can -bridge. We will reprogram the BMS.

Aha,Buena sugerencia...😄 Si necesita actualizar su Leaf, puede contactarme... helen@vivnevs.com o Whatsapp: + 86 18717786639

His Leaf is 2016, generation 2 and he upgraded to 62kWh battery with us.

The other 62kWh customer also had demonstrated in our channel had already installed our pack. He hired a nearby car repair shop to do the swap, which is not difficult. Only need to remove and fix some bolts and nuts. He now got 378kms on his dashboard, which we shared in some of the fb groups. Now he can plan long distance trips and not afraid to turn on the AC...

For the 62kWh, there will be total 6 modules. Module 1, marked as Module ABC, dimensions of Module 1 is : 439*357*160mm. Module 2, marked as Module DEF, dimensions of Module 2 is 439*357*160mm. Module 3, marked as Module G, dimensions of Module 3 is 613*439*115mm. Module 4, marked as module H, dimensions of Module 4 is 613*439*115mm. Module 5, marked as Module J, dimensions of Module 5 is 400*912*110mm. Module 6, marked as Module K, dimensions of Module 6 is 384*912*120mm.

@@VIVNEHelenMaothank you for that, much appreciated.

@@ianlighting100 It is our pleasure.

Thanks for the suggestion. We will update in the channel if we got anything for this car also.

The bigger battery version of Ioniq has water cooling, the first version doesn't. 🙂

As long as it is Leaf, then our battery pack will work. Please contact us then.

Yes, brand new. We only use brand new CATL A grade cells. It is NMC. Please kindly email to: helen@vivnevs.com or add my Whatsapp: + 86 18717786639 for the service cost. Thank you.

Yes, some other customers had also recommended this model. Please keep following our channel. We will update if there is battery pack for this model. Thank you.

This is because when we do the tests, we only use the testing BMS, which is not re-programmed yet. If with the re-programmed BMS, will be no such problems.

We had received an email from Sweden and was replied. Please check your inbox. Thank you.

@@VIVNEHelenMao i am in the US its been a few months ago. i will send again.

The Leaf owner was driving with 50-70km/h. 567 kilometers is the data the Leaf owner actual drove. Car range is affected by many factors. Could you let us know more about you first? We provide 2 year or 80,000kms warranty. You can email to: helen@vivnevs.com or add Whatsapp: +86 18717786639

That's a good suggestion. Actually around the globe, there many Leaf cars are now driving with our Leaf batteries.

No need to upgrade the rear suspension. The 62kwh battery is only 85kgs heavier than original, just as taking an adult in car.

Yes, to provide battery upgrade and replacement for Nissan Leafs is the only thing our engineers focused on. Every detail is considered to perfection.

We had re-programmed the BMS. So there is slight deviation from the Leafspy readings and the actual battery pack situation.

Thanks. The estimated car range of a new 62kwh pack is 430kms.

Good suggestion. Please keep following our channel. Thank you.

Bmw i3 and some Tesla models would be the next stage of our work.

We are considering to shoot a video on how our technicians re-program the BMS. Hope can be soon. Please keep following our channel. Thank you.

@@VIVNEHelenMao Thank you. I think this is an important part of the process to help convince people. Some battery upgrade companies use a can bridge that is separate. Some use a can bridge that we think is hidden inside the BMS. Your approach is to reprogram the BMS. Whichever approach is used, the important factor is how it works long term, not immediately after the install. So if you can include in your video some detail on why and how the new BMS can cope with battery degradation long term would be very helpful.

@@ianlighting100 Reprogram the BMS is to solve the problem fundamentally. There is Leaf owner drove with the reprogrammed BMS 2 years now with no problem. Since only the mileage parameters are modified, all the rest functions and safety strategy remain the same as Nissan original.

and if I will replacement it into my car in Jordan 🇯🇴, How much does it cost with shipping and everything?

0-80% fast charging takes about 1 hour and 15 minutes, 0-100% takes about 2 hours. LFP batteries cannot be used on Leaf cars. Car range is 430kms. Fast charge time from 1 to 2 hours.

Total agree! Leaf is really a nice car. With our battery upgrade solution, car can even run further than new!

We had purchased the tesla car in our factory recently. Hope in the near future, we will be able to devote some energy to this area.

@@VIVNEHelenMao I wish youd switch to the newer and cheaper sodium battery on your upgrades. You guys will get a lot more orders.

@@tobyswesternwear Nissan Leaf car has voltage request. Maybe for other cars later will consider.

@@tobyswesternwear Na -ion cells are larger and less energy dense so not a good fit for the LEAF. More expensive per kWh currently. Will be better for short range vehicles and other applications.

Thanks for the suggestion. We only modified the parameters related with the mileage display, so it can display the whole new mileages. All the rest Nissan original functions and safety strategy remain the same. Nissan did a perfect job on this. So it is still safe and secure in the long run. We had customer installed our battery over 2 years and drove for more than 9,4362kms, SOH still got 96.59%.

@@VIVNEHelenMao so can I just push you for a little more detail please? When the displayed mileage is increased with the new battery, is this fixed? Or does the maximum displayed mileage decrease (as it should) in line with the reducing battery capacity as the battery gets older? Thanks.

@@ianlighting100 It is not fixed. The displayed mileage is based on the energy economy. We had at most displayed 558kms on our Leaf. Customer side also feedbacked had run 567kms actually. We also did the test on full highway, when the energy economy is high and the displayed mileage is only just more than 300kms. When the battery gets older, the internal resistance of the battery increases，the battery capacity will reduce. The maximum displayed mileage will also decrease, but it mostly related with the energy economy as above mentioned.

@@VIVNEHelenMao 94362 km and lost around 4% SOH ? have shipped in europe somewhere ?

@@emericdobos531 Yes, this is how Leaf owner feedbacked. We had shipped to France, Spain in Europe.

When we doing the tests, yes, test in extreme conditions...

a review would be good. Third party review is helpful.

Yes, the 68kWh can fit into your 2nd gen Leaf. No need specially to make harness or customize to bottom. Only the 68kWh battery is 25mm higher than original. So will need to use 10 solid spacers when installing. Please check the other video in the channel, which have the explanation on the solid spacers. Thank you.

@@VIVNEHelenMao Excuse me. But 2015 Leaf is first generation. Right? I have the original body style. Your answer to me is 2nd gen Leaf, was that a mistake? SO 68 Kwh only fits second gen? Or both? And what is the range for 68 kwh compared to 62 kwh? How many miles or km? Thank you

@@roamlikekane 2011-2012 is the first generation. Your car is 2015, so it is the 2nd generation. The 68kwh can fit in any Leaf models. The car range of 68kwh is 470kms, with 40kms more range than 62kwh. Thank you.

@@VIVNEHelenMao Thank you kindly

We usually drive in D mode. In summer time, if with the air conditioner on, depletes battery by 10% percent, yet depletes more when in winter time. We had also tested the range with full highway and air conditioner is on the whole time. Please check the other testing videos in the channel. Thank you.

@@VIVNEHelenMao Ty for your reply. I notice the one you are referring to is a Generation 2 Leaf or with new body style. It is a different model than the one you test in this video which is Generation 1 (forgive me I don't know the model classes too well). But I can tell you mine is a 2015 Leaf with the Gen 1 body style, in fact it looks like the one in this video with same white paint. Do you think that the air conditioner depletion is less compared to the newest generation to the previous generation? You claim 10% depletion with air conditioning but what about Generation 1 style of Leaf? If you can test air conditioner depletion with Generation 1 it might be better example because I think the newer Leaf have better technology in the software or build to distribute energy from air conditioner than previous Generation.

@@roamlikekane Yes, according to our experience, the air conditioner depletion is less compare to the newest generation to the previous generation. But there is no quantitative data.

Ok, we are also planning on to shoot a video on this now. Please kindly following our channel.

Are your referring to the service plug? For your reference, we use the original service plug.

Yes, we can reprogram your existing BMS. Send your existing BMS to us, then we will re-program for you. The re-programmed BMS will be shipped together with the Leaf module package you bought.

Thanks. It is NCM.

The motor of Leaf is not big, only 80kW. We replace with big CATL cells, which generate less heat and bear a smaller C rate. So no extra cooling is needed.

@@VIVNEHelenMao hello - 1. if this have smaller C charge- with what max and average speed you can charge these new batteries? 2. How long will charge 62 or 68kwh battery? in AC wallbox and DC fast charge 3. Do you need to charge 10-80%? 4. Would it work with charging with that new chademo-ccs adapter? Like this os similiar th-cam.com/video/HT2JuG6N-Yg/w-d-xo.html or like ccs2 to chademo adapter from Dongguan Longood Technology?
