Temperature valves are in ohms not volts

I have done some teseting on the BMW battey connectors
I think the best way to use the newer 34Ah batteries in the old BMW hybrid packs is to swap the pins in the connectors and use the same BMS system.
There is a risk of shorting the cables so if you are doing this I recomend that the pins are ...

They are 15 ohms on the first version of HV packs.

No, you can buy these to.

Depends on the HV pack of the car:
- 81315A94550
- 83302353361
- 83302353250

Further good to know: the EOS security code can be generated online to.


Hi, thanks you obviously know what your doing.
The only 10 digit numer on the HV pack name plate starts with 0211 and ...

Thank you for the reply Venigo I have ISTA but i dont have a EOS tester. Is it just BMW who have these?

I have a gen 1 BMW 330e F30 and I have purchased a gen 2 battery pack to try and get a better range.

Does anyone know the best way to use the gen 2 batteries in the gen 1 pack so that the car recognises it.
I tried plugging the blue plug into the s box unit with the new gen 2 batteries but the ...

Hi all was very helpfully pointed over here from diy electric car forum, and found this thread contains tons of info I was looking for, I have 3 complete 330e battery packs that I plan to use a total of 15 modules in a 5s3p configuration, will I be able to use all 15 cell monitoring slaves chained ...

Thank you for the reply sprocketman - I knew the published pack voltage, but not the upper and lower limits.
Yes - have already tried Tom's modified SimpBMS on a Teensy: need to look at that in more detail on how to use it with the Tesla Mk2 charger, but at least it showed the pack I'd bought off ...

Hi All

First post but long time lurker - now have an e330 battery pack and Tesla Model s Charger (rev 2) to play with along with one of Damien's Tesla boards and am about to put it all together: being late to the party means I don't have newtis to consult - can anyone please advise what (safe ...

Happy new year and thank you for the amount of work you share under this forum!

I own a BMW X5 40e PHEV and I would like to increase the HV battery size in order to achieve at least 40km of range (I estimate 12kwh of usable battery). From your huge experience with phev batteries, I kindly ask for ...

Try these and see what happens (should be on) Precharge first.

Hi,

Thanks

I still have a few errors? do i have too many files?

i have loads of these errors:-

What sort of Arduino? I put some notes on CAN data collection with Arduino One, Due and Teensy in the wiki:
https://openinverter.org/wiki/Getting_started_with_CAN_bus


I am triying to get the Ardunio Due to work. i havebeen through the WIKI page a few times but the ardunio program wont run with ...

I am not sure if I am collecting all the can messages as there are a few errors. I might try the other can bus and see if there are different messages on that one.
I am using an arduino to collect this info. I couldn't get savvy cam to work
Do you have any tips.
Regards

Andrew

Hi sprocketman, I'd not suggest connecting 8 modules to the voltage measurement connector of the S-Box (three thin orange wires), that will probably exceed its capabilities significantly! No problem with the current sensor on its own up to the capabilities of the module I expect. There are lots of ...

Hi,

Has anyone worked out a schematic for the sbox pcb?

I have made a little progress, if you send frame 0x300 with the first byte set to 0x9f (rest of bytes to 0xFF) it will turn "ON" the small blue relay on the PCB. It makes a very quiet, but nice noise.... (sending 0x5F turns it back "OFF ...

pilt, thanks, I will certainly look at the additional 12V line. I think we will need CRCs understood to get it to respond to inputs like Tom reverse engineered for the modules. I'm not assuming that is possible unless we have logs on this can line in a working vehicle, which will be a challenge ...

Hi, yes, it is absolutely possible to use the S-Box in its original form to output current and voltage.

I've spent quite some time reverse engineering the CAN messages up to about 300V and about 50A so far. I will dig out where I've got to and share. I'd really appreciate some sharing of real in ...

Does anyone have a pinout for the 'safety module'? Looking at re-using it but didn't take a note before I adapted the loom.


Hi,

Which pin out do you need?

this one?

Hi

I had some problems when i tried to send signals to my tacho on a 2008 Toyota until i found this web page

Adding the coil from a small relay in the circuit made the differance.

It wont work on all types of tacho but ...

Thanks Tom I understand now.

Hi Tom,

Is it possible to read more than 6 modules? I connected 11 (I need to make new cable for 12). It reads 11 modules but only displays voltages for 6?

Thanks again

Andrew

I am open to offers on the price and will depend if it is being collected. I nearly killed myself moving it on my own.
