I've tried using a CAN-bridge to shift addresses in the past with the older (panasonic) packs, that hat unexpected results (not nice...heavy unbalance). So best to use two SimpBMS Was they really out of balance or just reported as such? I'm going to be attempting this soon. they were -very- out of ...

I have 2 of the 36kWh eGolf packs that would probably mean that I need two SimpBMS to cover them both? The other option I would like to explore would be to add modules from the other pack to go from 88s into say 108s or similar. Has anyone tried that, would it work? Do the modules need to be in the...

Thanks again, didn't look for air cooled ones

ordered some of these:

I'm looking for multiple Volvo / Eltek chargers for a boat project on a budget...

Volvo IP67 charger can be found under those PNs
31394702
30659929
31453939

must include the water cooling baseplate.

Thanks for the info!!

I'll use them and will look for some more

Hi @arber, no issues with 3x eltek on same canbus? or do they need individual canbus per charger? I have to build a big charger for a boat, with sets of 3 chargers to enable for 16A / 32A and later even 63A three phase and have to decide what I'm going to use. (on a small budget) I do already have 3...

Oh nice, do you plan to work on it yourself? I like to lie to myself and say 'yes'... But I don't have the skills or the time, so probably best to send it to someone who can ;) would be great if I could use the drivetrain in boats, or others in cars (for boats, reverse must be as fast as forward)

I think I have the most important parts.

no separate charge port module.

the 11 kW charger is with Tom de Bree already

These modules are used in Volvo PHEV's, I don't know what exact modules are used in what models. Also the 'London Cab' PHEV's have 3 strings of these style modules.

They exist also in 10s, (others also maybe) but I don't know if the BMS is the same.

I'm getting an id.3 battery soon, and asked for a price for the propulsion parts, charger, charge port, wiring, etc.

are there any other parts of interest to also take from the car?

They were always quite expensive because the cells are bolted so you can reconfigure them. That being said: they can indeed be quite bad SOH, but they are air-cooled by the car (and maybe heated also?), coolant from car goes through a radiator inside the battery and a fan blows the air around. So ma...

https://m.facebook.com/pg/Carel1956/posts/

Carel Hassink, he sells all kinds of modules. he was actually using BMW CMU's there.

I don't really see where such a bulky low Ah pack would come in handy...

Please note that I updated my statement that 5V is enough to use the slaves...it isn't when I try to use more than 1 slave (need 12V than)

Weight: 59 kg's / module

Hi @jnsaff

length: 1370 incl. connections
width: 340
height 80

connection on one end extends about 90mm (included in the 1370mm length)

I've learned that with the Samsung (gen2) version, of the 8 modules with a CMU PCB on board, the 3 of them that don't have 8 cells of 'slave' modules connected, also don't give values for those slave cells when you do connect them. This is a difference with the gen1 version that does support this. t...

Hi @arber,

No v-sense connection on the charger?
I guess due to big cables not needed as much as other chargers...but it's also a safety feature for catching bad connections...

Hi all, I have some Model3 batteries that I'm not using yet...so want to part with some...as it adds up fast... Prices ex tax (if applicable) and they are based in NL short range is probably 50 kWh (not sure, might be more) long range 75 kWh I have a 'short range' with 'long modules' that is partly ...

Thanks boekel! OK sorry if I'm being a bit stupid but what alterations to the RX and TX do i need to make on modules 2&3... I tried Brysons suggestion but no joy! Many thanks for your help! look at the last module...where does that connect? the same should be done with he middle modules. so use...

How many modules is the BMS recognizing? All four? Only recognizing two modules (four wired up) . All four leds are flashing. Really at a dead end with this one as have checked wiring countless times... any more suggestions would be fantastic! Jack Jack, the way you wired (picture you posted earlie...

note that 5V is also enough on the 12v line to wake up the slaves!

Thanks,

That's good to know, I found only 12V value from SimpBMS manual.

so you only have to use the SimpBMS 10 pin connector for the slaves

I have...let's see if the UK is ready for normal shipments :p

Nice work!

note that 5V is also enough on the 12v line to wake up the slaves!

update: when using multiple slaves, 5v doesn't do the trick, I need 12v then. for single module testing 5v seems to work (simpBMS only powered by USB)

I remember someone looking for a bms control unit for a Fluence...but don't know where..

I've got two:

293A0HB86B
293A0HB85C

available for shipping costs if anybody needs them.
