SHENZHEN FACTORY TECHNOLOGY battery packs- is it real?

[noelho]

Just FYI, I have a VIVNE 50kwh kit in transit for my eNV200. Shipped the other day. I'll probably do a little video of the fitting process. I really like VIVNE so far, they've been good to deal with. Great communication, and questions answered instantly. Nothing that doesn't make sense from a technical perspective. Looks like they use a specialised international battery shipper for the packs too, these guys, I did google translate as the website is all in Chinese. Again, looks to be all above board and well thought out. https://www-an--yun-net.translate.g...l=auto&_x_tr_tl=en&_x_tr_hl=en&_x_tr_pto=wapp

Nice. Looking forward to it!

In other news, VIVNE have released two videos. One is their custom OBD2 reader, so you dont need a phone + leafspy to get up to date battery details:

Helen sent me one of these if anyone wants to know about it feel free to ask. Happy to do some photos or videos.

I'd love to see a video. It would be nice to see how it compares to leafspy. Would be nice to have something permanent in the car.

Check out the videos on VIVNE's YouTube channels. I think both Cora and Helen have sample videos

How do you know the asian builds are using new batteries?

All chinese batteries have a qr code on them. Plenty of article online on how to read and interpret the codes, the basically list manufacturer, manufacturing date, battery grade etc etc. I believe the grade A CATL cells are fully traceable through the catl production process but I haven't independent verified this.

 

[NeguE]

can someone explain what exactly dothis LBC ?

I’m definitely following this, I’ve had much curiosity on these CATL packs. The only website that looks legit and to the point is vivnevs. They have options to pick down to the kWh and generation. They also offer / supply the B24 22-36pin adapter and the CAN Bridge.
They also have a YouTube channel
https://www.youtube.com/@VIVNEVS
Out of all the Chinese companies, this one appears to be the most “put together”
They claim to have driven from ~100% SOC down to completely dead with a 62kWh battery swap and went I believe 567km. Their channel hasn’t been out for long, but it’s worth a watch.
I've been seriously considering them, but I'm holding off until there's a documented case of someone installing these with minimal issues and successfully driving for an extended period of time.

I bought a 22 pin to 36 pin cable adapter from VIVINE through Ali Express. I sold the 2012 Leaf SV instead of fixing it and bought a 2016 Leaf S with a good battery. They refunded my money for the adapter because I "changed my mind". I thought the product looked good and the return went well. Ali Express will offer returns for 90 days and I do not know how they affected the return, but you end up asking VIVINE for the return.

I recently bought a 50kWh kit from VIVNE (Shenzen Factory), going to use it on a e-nv200.

I guess I'll have to wait like a couple of months until it arrives to Barcelona (spain). The kit comes with an original reprogrammed BMS and all the cells are from CATL.

I'll keep you updated

Has your battery arrived? Very anxious to find out if this is something I can trust spending money on.

Hi, mine arrived in nz on the 6th Jan, picked it up last week. All beautifully and carefully packed. It's a complete kit with everything you need for installation except tools. We haven't yet attempted the install as I'm waiting for the correct connectors to de-gas the aircon circuit for the battery cooling. But so far very pleased with the whole experience dealing with Vivne. They are very thorough.

Just a nudge, but could you possibly take some pictures of what’s under the black cover if you have not installed yet? Would love to finally be able to look at the craftsmanship of these modules. Not only for cell validity, but module assembly in general.

I would love to see this too and the bus bar thickness as well

I was planning to lift an edge and take a snap of one of the bar codes. A bit of trawling through their website will show you what they're up to. Laser welded bus bars and tags, pretty standard for this type of module. Tbh the bus bar doesn't have to be that massive to pass that current. But yeah I'll have a bit look and post it up. Transparency on these things is good for all of us.

I am finding the cost plus shipment and tariff fees for a 2013 Leaf plug and play 62 KWH battery from www.Vivne.com around $9K, and modules amounting to 58 KWH from GreEnergy around $6300. Toying with 2nd option and how difficult it is to replace modules. Wondering if anyone can share their experience replacing modules in a battery shell. Easy, difficult, time consuming???

Looking at the gre energy one, I would like to know more about the high voltage disconnect, looks like it can't be in the original position,if this is the case how can it be disconnected in the car? Might pose legal issues, but the price point is definitely better

Yeah. The layout looks strange. There are structural elements in the pack that prevent you from arranging the big modules in that manner. I'd be worried if they cut structural elements to squeeze those modules in.

Unless I'm misunderstanding and the pack in those photos are from the VW id3?

The thing is with vivne is it comes as a complete kit down to nuts bolts spacers, sealants.everything comes preconfigured and guaranteed to fit and work straight into the original enclosure. If you can find another supplier that thorough by all means order one and let us know how you get on. I'm sticking with vivne for the extra cost. So far my experience with themm iss 100% on the money.

I think they will be the " go to " battery suppliers,so far what I have seen, they look the neatest most professional repacking option, especially like that the case doesn't have to be modified, I would love to see 160kw being discharged (what the ze1 e+ can load) with a temperature camara showing where and how much heat is produced, I did see recently a video that they produced, where they loaded it to 20kw but I would like to see 160kw, I do realize that the battery would not see that loading for a sustained period of time in real world conditions, but I would like to see them test this even for a couple of minutes, for me that would seal the deal and give me a lot of confidence

So the mechanical is taken care of. What about the SW compatibility? What steps does the kit include to adapt the BMS to recognize and accept the switch?

From what we know, they flash the new battery size into the BMS. and those are the only values they change. No need for any CAN bridge and the BMS logic for balancing battery is untouched.


There is supposed to be some kind of pairing process using LeafSpy, but thats about it.

 

[Dala]

Wow that video was garbage! They are using the Russian closed source program for flashing the BMS, and they do not show any parameters what has actually been changed. It is NOT as simple as making 24kWh into a 50kWh battery.

You need to tweak so many lookup tables with offsets, voltage limits, degradation data, internal resistance calculations, power reduction tables, temperature maps, charging maps, fastcharging maps, etc. It's not even funny how dangerous it will be long term to use the wrong parameters here.

Thankfully Safetyuggs is working on an open source version of this flashing, this Vivne stuff is scary to watch!
