Re: Peugeot e-208 CATL modules BMS interface [SOLVED]

Good to hear Richard, I do believe the original BMS harness I have seems to have the wrong pairs twisted together! Ah... that would not help... my harness seems correct, but still the comms seem much more glitchy when the inverter is running. Particularly when starting up / accelerating / doing reg...

Re: Peugeot e-208 CATL modules BMS interface [SOLVED]

inaglasshouse, Richard. Are you still having problems with comms to the salves? Hi Joe Thanks for asking. All good here now, thanks, slaves chatting nicely. I have also got the cell balancing working, and made a few minor changes for the sake of comms robustness. In test rig mode anyway, with every...

Re: Peugeot e-208 CATL modules BMS interface [SOLVED]

Good to hear you have got things working. I think I got it right as Pin 1, 7,3,8 come/go back to Module N-1 or Master and 12, 5, 10, 6 go on / come back from Module N+1 or loop back. By the way, you can set the slaves not to have the loop back and do this internally. Yes, I saw the internal loopbac...

Re: Peugeot e-208 CATL modules BMS interface [SOLVED]

and so on until the end when Pin 5 loops back to Pin 12 and Pin 6 to Pin 10, the end of the daisy chain. I think (using the pin numbering system in play in your post), this should read: "until the end when Pin 1 loops back to Pin 8 and Pin 3 to Pin 7, the end of the daisy chain." Apologie...

hi @inaglasshouse I am new on this forum, but I have some knowledge about those batteries. If you go throught daisychain init without errors, but cant communicate with slaves, please use as first command after daisychain init " readAllSlaves(0x00, false); and write me what was returned. Thanks...

Re: Peugeot e-208 CATL modules BMS interface [SOLVED]

I thought I would put together a list of things I have found out about the Peugeot e-208 CATL modules. Firstly a big thank you to Clanarn for designing the master board, bexander for the software and chris01290 for software and general advice. The e-208 modules use the MAX178xx family of devices. e...

Re: Peugeot e-208 CATL modules BMS interface [SOLVED]

Some progress, but now a bit stuck - help appreciated. Status: - microcontroller talking to MAX178741B master board. Using code published on here, many thanks to authors (Anton and Chris mentioned in header, apologies if I should also thank others) - about 0.8v ac can be seen between TxP and TxN, as...

Battery pack is here, BTW. CATL 6S2P modules from a Stellantis product.

Re: Eee Gee

At the moment we are still paddling in the shallow end. But I do have the charger awake and talking via CAN. We seem to be doing enough to keep it alive and happy, reporting status of external type2 connector, and indeed charging the pack. AC slow only. DC is later. Much later. https://images.square...

Re: Eee Gee

Hi Igor, Interesting re (lack of) transfer case. That might prove the right way to go. I will do some more research... In my mind (dreams!) version 2 is twin motor, one driving each axle diff (hence motors would definitely require some reduction gearing), with a second battery pack also added. But l...

Re: Eee Gee

Very nice. So ZombieVerter for the Leaf then? No. Home brewed code! Plug and play generic microcontroller(s) and other hardware. Yes, I know, masochism, but bear with me. The back story is: I used to be a proper software engineer (robotic systems) but for the past 20 years have been sucked into the...

I have a couple of MAX17841 interface boards left if someone is interested. 40eu. Pm me for schematic. Hi, I would be interested in a board. I can't PM you, probably because of a minimum post requirement... I'm new around here. For me it's early days on a G Wagen EV project in the UK, using an e208...
