Info on BMW hybrid battery packs?
Does anyone have a source of detailed info on BMW hybrid battery packs?
One of the challenges I'm facing with my bike project is finding a source of "splittable" batteries. Of course 16850s are an option, but I'm keen to recycle where possible
The 740e pack looks very splittable - but I can't find any data on the module specs...

Re: Info on BMW hybrid battery packs?
This should get you started :
https://www.newtis.info/tisv2/a/en/g11- ... 1VnZ8phPwk
Just picked up one on ebay myself from a 2018 740e for 950 Euros delivered. Beauty of these is they are full voltage (360v ish) and can dish out the amps annnd you can add more in the future for extra capacity.

Re: Info on BMW hybrid battery packs?
Ah, so you bought it. Bargain!!
Thanks for that info. It’s rare to find a small OEM pack that has decent voltage AND current.
I hope you’re going to take the lid off once it arrives...

Re: Info on BMW hybrid battery packs?
I wonder who might be able to control these...
I would believe the canbus to be the same between these and the BMW I3 modules.

Re: Info on BMW hybrid battery packs?
That service manual info is brilliant. Thanks JB!
Is there any data available on the cells? Given it's a 96s1p pack, those little 34Ah cells must have an unusually high current rating. Maybe that's why the pack is quite heavy?
As it's based on 16s modules, the pack looks reconfigurable to a 32s3p arrangement. This would give me the 120V I need (I'd like to go higher, but I haven't found a suitably low-K motor yet...). Battery current rating in 3p configuration would be way in excess of what I need.
So no need to bother with any battery cooling!

I'll certainly open it up when it arrives:) Hope Tom is right about the bms slaves. Would make life quite easy.

Re: Info on BMW hybrid battery packs?
Exactly! If the BMS will work with Tom's controller then I may have finally found the battery pack I need...
Of course, I'll probably change my mind next week, but that's good enough for now.

Re: Info on BMW hybrid battery packs?
It's not unusual for cells used in hybrids.
They're slung underneath a tank (7 series)... why make them lightweight?

True! 120kg will barely register on one of those things. That's 2/3 the entire weight of my bike!!Kevin Sharpe wrote: ↑Thu Apr 23, 2020 9:48 am They're slung underneath a tank (7 series)... why make them lightweight?

Re: Info on BMW hybrid battery packs?
Considering its a G rev car they probably need the weight to make people think its a real BMW:)

Re: Info on BMW hybrid battery packs?
How many amps do you expect to be able to safely pull from these?
If at first you don't succeed, buy a bigger hammer.

Re: Info on BMW hybrid battery packs?
Battery just arrived. No idea on power beyond what is listed on newtis. Will find out when driving.

Apparently the cells are Samsung SDI 34 or 37 Ah, but not found a data sheet anywhere yet...

Re: Info on BMW hybrid battery packs?
I found a few news articles discussing the hybrid that stated the electric motor was good for 111hp (82kW). Based on voltage that works out to about 230 amps? Someone check my math.Jack Bauer wrote: ↑Fri Apr 24, 2020 1:48 pm Battery just arrived. No idea on power beyond what is listed on newtis. Will find out when driving.

Re: Info on BMW hybrid battery packs?
They upgraded that pack to ~12kWh in later revision of that plugin fleet.
Not sure it's only achieved via denser battery chem or increased size (number of modules) of the pack (or some combo of thereof)..

Re: Info on BMW hybrid battery packs?
So the canbus for these batteries is NOT identical to the I3/I8/Mini.
The command messages do not follow the same structure.
0x80-0x85
D1-D8
D4 commands the starting of measurents for the I3 CSC modules
D5 commands it, or atleast it seems, for these Hybrid packs.
As I do not have a module I cannot try testing some more findings, but taking captures from Damien one should atleast be able to play back the command message to get the info out of each brick.

Thanks Tom. I'll have a play with them soon and post up what I find.

Re: Info on BMW hybrid battery packs?
Most of the BMW hybrid packs seem to have 26Ah modules. I just picked up a 330E pack, which has five modules, rather than the six in the pack Damien acquired.
I unloaded it from the van and dismantled it this morning. Really nicely put together!
I weighed a module at 12.7Kg, which equates to something like 120Wh/Kg.
