Nissan Leaf DIY battery modules 50kwh before shipping

[@rogerbedell4056]

A suggestion: It would be nice to also have a way to reuse the old Leaf battery modules, e.g. as a home battery (powerwall). If you could offer a kit for this along with the Leaf battery upgrade kit, it would reduce my overall cost since I can re-use the old cells in my house.

[@VIVNEHelenMao]

Thanks for your suggestion. Our technicians are considering this possibility. You are also welcome to discuss more details with us. You can add my WhatsAPP: [phone] or email to us: [e-mail]

[@pashko90]

I have a lineup of 48v and 12v boards and kits to reuse modules, since this is what I do here in California. Since we have a sunshine tax anyway, we have to take advantage of it :)

[@puntabachata]

There is! See Dala's EV Repair. It's an open source project.

[@johnbarlow7524]

Ask yourself "why am I replacing the batteries"? Typically they have lost so much capacity, they are better off recycled, and find other (newer) batteries to use as a power wall.

[@Allewis55]

Thank you for your informative videos, Helen. What is the weight of the original 24kwh battery, and how does this weight compare to the weight of the 40kwh, 50kwh, and 60kwh batteries that you are offering?

[@VIVNEHelenMao]

Thank you for your affirmation. The weight of the original 24kWh is 275kgs. Our 40kWh battery weights 253kgs; 50kWh battery weights 299kgs, nearly the same weight as original 24kWh; the 62kWh battery weights 360kgs, 85kgs heavier than original, just as taking an adult in your car.

[@jasong7374]

I would love to test these batteries, but struggle to trust overseas supplier, also do you have own bms? Or use Nissan one?

[@VIVNEHelenMao]

We use the original Nissan BMS. But we can do BMS programming to display the correct new mileage on the dashboard. You can first add my WhatsApp:[phone] or email me: [e-mail] We can introduce our factory to you by video calls.

I feel the same

[@VIVNEHelenMao]

@@spiderrman2099 No rush. We can spend more time getting to know each other. You can share with me any technical questions about the Leaf car battery upgrade.

[@pashko90]

Jason, we signed the agreement to work with this company. I'm located in Los Angeles area. I'm serving basically whole west coast and warranty claims(if it's gonna be any) will gonna go thru us.

[@olivieretcecilepineautexie9351]

Thank you for this vidéo. Few questions: 1- is there an insurance and for how many time or km? 2- Do you've got a shop in Europe, or a association with another company (garage...) to change battery (I'm in France)? 3- my leaf is a 40 kwh. It still works very well. So I don't need to replace the battery for the moment. Your pack could be put on this car? Thank you.

[@VIVNEHelenMao]

Thank you. We provide 2 year warranty or 80,000kms warranty. Trust soon we will have partner in Europe. Yes, our pack can be put on this car.

[@pashko90]

Hi. I have a guys in Bulgaria who can help you out to trade your pack in or can sell you empty case if you need one.

[@rdflo6739]

Is there any testing done to see if the original 24kwh bms can balance the 50kwh pack? Thank you for the video!

[@VIVNEHelenMao]

The original 24kwh BMS ( if before our re-programming), is also can be used on the 50kwh pack, just can not display the whole correct new mileages.

[@rdflo6739]

@@VIVNEHelenMao how does the new programming work? Can you do it remotely, or do you supply new Fw and instructions?

[@VIVNEHelenMao]

@@rdflo6739 We use the original Nissan Leaf BMS and re-program it. It is a very complicated work and only can done by our professional technicians. We send the re-programmed BMS together with the battery pack to customers.

[@Marsh-qx7ps]

Are these packed liquid cooled or the same flawed design passive cooling that Nissan used?

[@VIVNEHelenMao]

We replace the original soft pack into big CATL cells, which generate less heat and bear a much smaller C rate. Besides，the motor of Leaf is not big. So it is enough.

[@edwinjoshua2041]

Doesn't the CATL batteries need a coolent especially if you are driving long distance,?

[@VIVNEHelenMao]

No need. We replace the original soft pack batteries into big CATL batteries, which bear a smaller C rate and generate less heat.

[@edwinjoshua2041]

@@VIVNEHelenMao Thanks could you please tell me what is the C rate.

[@VIVNEHelenMao]

@@edwinjoshua2041 It is the rate. For example, the motor of Leaf is not big, whose peak power is 80kw and peak current is 250A. The original factory pouch cell is 67Ah (24kwh), so it bears nearly 4C discharge rate(with 250/67). We replace it with most up-to-date CATL high density cell, for example 120Ah cell, then it bears only 2C discharge rate(with 250/120).
