spent on time on the lathe and whipped up some brackets for mounting the ibooster. instead of using the volt’s master cylinder that came on the ibooster, I made an adapter for a Subaru one. This keep the hydraulic ratios properly matched, and no custom brakelines! 4CA954FF-F323-475F-967B-5F183CD2CB6...

contactors are switched via one of the relays on the board.
PCH-112L2MH,000
5amp 12v

Do the contactors have a econimmizer ?

Um... Does the ST Link actually do USB-serial? I can't find anything about that in the datasheets. I’m pretty sure I was reading the serial data from my Gen2 Tesla charger board with my stlink. But now come to think of it… it was my ftdi board. Whoops. Sorry! At least there cheap and now you can pr...

good find! ... So cell voltages are in ID 0x512, 0x514, 0x516 and 0x518 Pack current and voltages are 0x528 then cheers, okay so far all im seeing from providing +12v is: 0x200 0x202 0x204 0x206 0x208 0x20C 0x216 0x260 0x262 0x270 0x272 0x274 0x304 0x460 i pluged in a few of the cell taps and now 0...

okay so some success! did some more digging, loaded up "gm_global_a_high_voltage_management.dbc" i stole from opendbc https://github.com/commaai/opendbc into savy can and boom! i got cell voltages and temps

First video update ( an introduction rather) to the new house "id like to welcome you to my soon-to-be new home:" cuts to a dirty grey goose :P had a good laugh :lol: place looks great with lots of potential! happy for you Damien. glad to see some trees around, should turn into quite the ...

Electrical: Am I correct that pre-charge is needed at the start of charging in the same way it is for powering up the inverter? There is no need for recharging the pcs. precharge is only for the drive inverter to protect the drive inverter igbt’s from inrush currents and voltage spikes. It just slo...

sound like more room for error. Less junction points/transitions the better.

Best to just make a new cable. crimp ring terminals. Adhesive heat shrink.

No need to over complicate things.

If not, can anyone tell me what I need to connect to the programming port so I can access via serial? I'm not seeing a part # on the BOM or a clear pinout on the schematic. youll need to connect a stlink to the 3.3v, gnd, swclk and swdio pins on the programming port, i think on our boards its label...

I believe so. It was a complete and preprogrammed board. small chip? then its an stm Screen Shot 2022-01-16 at 10.33.14 PM.png I'll be honest, I've read through that several times and I'm not sure what I'm looking at, or more precisely how it helps.

I'm using one of Damien's Chademo specific boards. One of the stm32 based boards? I just soldered up my board, upon looking through the GitHub there’s : https://github.com/damienmaguire/Chademo-Fast-Charge-Controller/blob/master/ISA_CAN_Version/DataSheets/IVT-Mod_HowTo.pdf And https://github.com/da...

Not just sure what you mean re the CCS positive and the PCS. …….. you'd run the PCS positive cable through the CCS positive, so the CCS positive would have to come on for drive and charging? oh no sorry I mean the pcs positive would share the same contactor as the positive end of ccs. (Which is in ...

I’d put positive contactor/precharge and positive ccs contactor in the battery box. delete negative contactor in the HVJB, and run pcs threw the positive ccs contactor.

this way your not running pcs or ccs through pre charge at any point accidentally. And you cut back on contactors and the HVJB size

found this canbus switch board https://www.ecumaster.com/products/can-switch-board/
pretty neat and simple little board, dont have to program it to get it sending messages.

8 analog inputs and 4 outputs

seems like a prefect companion for OI

let SIMPBMS control the contactors, but use enable signals for the charger and the drive, to select one or the other. As long as the the inverter is controlling it’s own contactsors. if something else where to switch the main contactors off during drive, there’s a high Possibility of the inverter b...

Also, do you know if I need to go through the pre-charge stage when charging? if you are counting your charger and inverter threw the same contacts, then yes you'll need precharge for the inverter. you can never directly connect hv to a power stage without first precharging. but i would not recomme...

decided to do some digging again, and looks like the bolt, spark, taho hybrid and gen2 volt use the same BECM module. found this CVS file of the PIDs for the bolt, hopefully this is every needed to at least measure soc, soh, and cell voltages https://docs.google.com/spreadsheets/d/1sY5n8WFu52U6a4_mg...

thanks!
updated the wiki

johu wrote: ↑Sun Jan 09, 2022 9:56 pm Yes, indeed, never updated that.
The little 16-SOIC only handles small relays, so I thought beefing this up might make sense.

Awesome!

Just for clarity, how much can out_dcsw and out_pre sink?

i noticed when looking at the output driver schematic on git hub and the schematic on the wiki, they are in fact different. wiki version has: 2 driver lines paralleled for out_dcsw 1 driver line for out_pre github version: 2 driver lines paralleled for out_pre 1 line driving a N-chanel fet (ap9t18gh...

You can use each channel from Prius throttle for its own inverter brain

while this dose work and is quite simple, there’s no redundancy for each controller!

With oi, just link the 2 boards via can and map the throttle controls

Cheers.

not this revision with the NEMA B-face pattern, but the older design, which has the exact same mounting position for the leaf side, is in use in as variety of vehicles

I've observed that we might have to establish a standard format for wiki articles, but that's rather a luxury problem.

THIS! going forward it would reduce the amount of house cleaning needed in the future!

im happy to start, admit tho im no wiki expert.
