SHENZHEN FACTORY TECHNOLOGY battery packs- is it real?

[MikeinPA]

I have read the entire thread and I understand that changing the original Leaf battery for a CAT battery of the same capacity would only require the Cambridge battery and the BMS would support that change without any problem. I don't understand electricity or electronics and I am considering the possibility of making that change in my Lead 62, which has lost 50% of its capacity, through a specialist who has already successfully carried out many repairs and upgrades with LG cells with good results. Should I stay calm for safety reasons? It is an issue that worries me.

No CAN bridge needed if using the same size BMS. Unfortunately, there are no aftermarket CATL batteries available for Leaf. LG electric vehicle modules might make sense if you can find the right format.

No se necesita puente CAN si se utiliza BMS del mismo tamaño. Lamentablemente, no hay baterías CATL de posventa disponibles para el Leaf. Los módulos de vehículos eléctricos LG pueden tener sentido si encuentras el formato correcto.

24kw lbc, reflashed into 30kw. 40kw of modules. Sure, you can throw $1200 at a 40kw lbc, a bit more to get the second current sensor, a bit more for wiring loom. But then if your that hungry for range, buy a bigger upgrade. That video was an affordable upgrade we completed, using quality modules we know won't fail, and since the lbc can't access whole pack capacity

One thing I must ask, since it’s repeated question around here. Could you break down the “reflashing” process? No one here has documented a reflash of the BMS.

1. What does that mean? (To you)
2. Are we just putting in new voltage variables for the new cells?

I believe we’re all curious on what that process even looks like. Up to this moment on this thread, it’s been fully speculation that could even be done.

He leído todo el hilo y entiendo que cambiar la batería original del Leaf por una batería catl de la misma capacidad solo pondría la Cambridge y el BMS soportaría ese cambio sin problema, no entiendo de electricidad ni de electrónica y estoy barajando la posibilidad de hacer ese cambio en mi lead 62, que ha perdido el 50% de capacidad, a través de un especialista que ya ha realizado con éxito muchas reparaciones y upgrades con celdas LG con buenos resultados, ¿debo quedarme tranquilo por seguridad? Es un tema que me preocupa

If you can source LG modules like this, might be a good solution. Si puede conseguir módulos LG como este, podría ser una buena solución.

Are foreign manufacturers required to register with NHTSA?
Yes, all foreign manufacturers, assemblers and importers are required to designate a permanent resident of the United States as the manufacturer's agent for service of all process, notices, orders and decisions.

These companies desperately need to connect with somebody that has a Nissan Leaf and are willing to perform and document these swaps, or have a shop take the battery and do the swap while documenting it so that they can highlight whether or not they actually function and function well. Hell - reach out to Nala and send him a pack and have him document the whole thing.

The biggest issue I see w/ Nissan Leaf battery swaps (In the US at least) is that the only seeming "safe" way to get it performed is at a shop that's familiar with doing the swaps and all of the shops that do them charge a premium that makes it too difficult to justify. For example, there's a dealership/repair shop in Portland Oregon called EV Rides that will do swaps and even sells pre battery-swapped Nissan Leaf's. The problem is that you end up paying $17,000 for a 2013 Nissan Leaf w/ 50K miles on the odometer, electric motor, body, etc and a 62kWh battery pack w/ no guaranteed SOH. I understand the issue there is that they need to turn a profit and that the cost of the packs likely isn't cheap.

Why would anybody do that when they could get a Chevrolet Bolt w/ a 65kWh battery that was recently replaced under a recall w/ a renewed manufacturer battery warranty, active battery cooling and CCS fast charging at a dealer lot for several grand less? Hell - 17K could get you a Bolt EUV, Hyundai Kona or KIA Niro EV that still has a portion of it's battery warranty, active cooling, CCS, etc

IMO - for it to financially make sense to replace the battery on a Nissan Leaf, we've got to see these $7000-$8000 packs that people can buy and viably install themselves actually work and even that is going to be a hard sell for a lot of people. That way people who end up buying these things w/ heavily degraded packs for $2,000, or buying the shells can then do a swap and be in an EV w/ beyond 200 miles of range for less than $10,000.

I'm following to see what ends up happening w/ Riore's order pack and how it functions.

you have some workshop near barcelona, some in Madrid or myself in Galicia. Because I'm interested in some 62kWh battery module, please let me know if you upgrade to buy some of them. Take into account that a good diagnosys could lead to a battery affordable battery repair.
***************************
tienes talleres en BCN o en madrid o yo en Galicia. Yo estoy interesado en algunos modulos de batteria de 62, porfa avisame si haces el upgrade porque podria comprar algunmodulo. Ten en cuenta que haciendo un buena diagnosi a la bateria, podria llevar a que sea mas rentable repararla.

Respectfully, I must disagree. This entire post begins with the statement "Robert Luo. Apparently they make CATL NMC battery packs for the Leaf," which is a we have seen completely untrue. The packs they are making are not meeting any kind of safety requirements or indeed any requirement besides looking good enough to peel 5 or 6 thousand dollars from some trusting Leaf owner. The location of the garage is unknown, the cells are unknown, the modifications to the BMS or CAN communications unknown and these packs would never be let through customs without a ton of paperwork that does not exist.

Mods?

I have a Robert Luo 62 kWh battery and it does not work properly. I am still looking for solutions. A lady named Helen has agreed to send me a re-programmed BMS. I will let everyone know what happens.

That will be interesting.

So, just to be clear, you bought 24x new modules, presumably 180Ah, possibly labelled CATL?

Did you buy them as separate modules in a kit, or a complete Leaf battery pack in the case?

You had problems, so you’ve asked Helen at Vivne and she’s sending a reprogrammed BMS.

Is there a CANbridge involved anywhere in this? My guess is the Robert solution included one, but that the Vivne one says you don’t require it?

Please correct anything I got wrong in my summary there!

Do you know how long it will take to receive? Presumably you now have to take your battery apart to swap over the BMS. Are you up for that?

Before putting the Vivne BMS into the pack, be great if you could post some photos of it so people can examine what’s been sent.

Good luck!

It simply means, I hand over lbc + money, I receive back a lbc with different firmware.
24kw + 30kw is same hardware, so they can be flashed. 40kw and up are different hardware, I do not know if he can yet flash 62kw firmware onto a 40kw lbc, I believe he's working on it after I supplied him a 62kw lbc to copy software off and learn about.

Who is this guy you hand the LBC + money to? Is it one of these Chinese suppliers, or the Australia office you mentioned, or someone else?

Thank you for being open about this. A lot of people are trying to get a clear picture of what and how this all works.

Small detail but worth mentioning, some of Robert Luo’s videos on YouTube have the VIVNE logo on them but the name Written in Chinese.
I wonder if they are the same garage

Literally, hand. As in, watch over his shoulder as he does it. Hence I trust his work. It's hard to trust someone remote, no matter which country, when you can't see or touch or watch them working.

I think this is the same Robert Luo?

He has heaps of videos on his youtube channel. His latest video has a URL to his own website http://www.shenzhenfactories.com/:


However, his packs/modules look very similar to VIVNE's. I wonder if he is like a middle man?

He has another video a year old, and it shows how they assemble their modules. It doesnt look like VIVNE's garage, but it could be a separate garage where they assemble the modules?

Well - obviously this would be contingent on the packs actually functioning properly. Say they offer a kit that actually functions as advertised.

If it's non-functional, then we need some sort of PSA stating to avoid them.

Ok, that’s great. So you have a local tech guy in NZ who knows how to reprogram your LBC.

Can you get him to write a technical explanation here of what he is changing on the LBC / BMS that makes it work?

It will be very interesting to know if he thinks the 40kWh LBC can be reprogrammed to support 62kWh battery.

Aaaaaahhh, Ok, that’s a third 3 letter acronym. We got BMI, CAN bus, and now LBC. 3 letter acronyms suck because they can mean so many different things. Because there’s a C at the end of that one I can more or less guarantee there will be an LBC where the C means “college” and there will be a bunch of sweat shirts with LBC stenciled on them without even looking it up. High school swim teams also come up a lot in general. no idea why.

BMS is most commonly used across EVs. = Battery Management System
LBC is, as fas as I know, only used in reference to Nissan Leaf parts = Lithium Battery Controller.

They are the same thing. If you looked up the thing that controls the modules on a Nissan parts list it would say LBC. If you were talking across the wider industry you would say BMS as that’s a common term that everyone understands,

CAN is a message protocol used across all kinds of cars, not just EVs. So CANbus is the network that carries those messages.

Many Leaf battery modifications use a CANbridge. It’s a small device that can translate CAN messages to make them compatible with different generation hardware. Work pioneered by DalaEVRepair on YouTube.
