I have few questions / ideas Are contactor output transistors cooled good enough? I had such problem with zombieverter vcu. There is some space so maybe connect drain to some polygon? DRV8874 IPROPI output could be connected to analog input to measure actuator current. It could be useful for sockets...

SavvyCAN partially supports can-fd but there are some functions missing and when i try using frame analyzer it crashes. I had to load log from other application to see 32 byte frames. Canable works for me, but when using slcan firmware timestamps in savvycan are missing.

@cgalpin There could be problem with Savvycan CanFd support. It has to be enabled in connection window but it's only shown when supported canfd interface is selected (using qtserialbus so peak can and few others): https://github.com/collin80/SavvyCAN/blob/1999da88c5d6b32bd432b737ba1b60d1a15ff47b/con...

I don't know. I created this dbc and named this bit this way because when it's set contactors open and some (error?) flag is set in diagnostic information.

Precharge relay working is a really good sign. Contactors are controlled by bms, not by HCPU. HCPU only sends signal to turn on HV. BMS doesn't close main contactor and opens precharge after 0x200 because inverter voltage doesn't rise fast enough. Try manually sending inverter voltage high enough fo...

I recorded can communication from Santa Fe HEV. There were many differences in frames between HEV and PHEV but fortunately all 4 required frames were present, just with different data. Can you read inverter voltage reported by BMS? Can you change this value by manually sending can frame with differe...

How do you send diagnostic requests (UDS)? Do you use my script or some obd2 scanner? Have you tried UDS Scanner in SavvyCAN? If battery sends any can frames it should also respond to diagnostics. In my case just powering BMU through "Memory power" and IG3 is enough to respond to these req...

I only had BMU connected. All 4 frames (200, 2F0, 2A1, 523) are needed. When trying to close contactors i didn't look much into messages coming from BMU, i used uds.js script to see diagnostic information. You should see ignition state changed from 0 to 00000100 when 0x523 (0x60, 0x00, 0x60, 0x00, 0...

Santa Fe has the same SRS input on pin 13. It wasn't needed to close contactors but maybe bigger (full EV) battery needs it?

I added short description of my battery in my thread: viewtopic.php?p=62256

I got it working. There are probably still few warnings but i can charge and discharge it. There are 4 frames needed: 0x523 - ignition and inverter status 0x2F0 0x2A1 - inverter voltage 0x200 You can find SavvyCan script to run battery, script to read diagnostic information and DBC file at: https://...

@elco I have Hyundai Santa-Fe PHEV battery working on zombieverter VCU.

I think it should be possible to use stock BMS. Looks like a lot of CAN messages are the same or similar between different Hyundai / Kia models and i have Hyundai Santa-Fe PHEV battery working using Savvycan script or zombieverter (there are still some obd-2 errors, but probably not critical)

0.14 A sounds like BMU is doing something. Are you sure your can interface is working correctly? If it has two buses you can do loopback test to verify it. You can also measure ac voltage on M-CAN and G-CAN, if it sends anything you will see ~0.3 - 0.6V. Maybe some CAN frame is needed, for example i...

SDC could be solar dcdc converter. I think 500k / 2000k is often used.

cgalpin, does it draw any current from 12V? What CAN interface do you use? Ioniq 5 uses CAN-FD so frames could be sent but treated as errors and not shown

RoyBoy, check if battery draws any current from 12V, in my case it's about 300mA. Check if there are termination resisors on CAN bus (120 or 60 ohm)

I know there are BMS's available such as SimpBms, orion bms or fox bms, but they are either as expensive as my whole battery or have to be modified. I think it shouldn't be difficult to use current bms, there is only few can frames missing and that's why i need h-can log

Hello, i recently bought temporary battery (37501-CL500) for my ev conversion and i'm trying to close contactors. EB 12 connector has similiar pinout to other models and i managed to read some data via OBD II. PIDs are the same as in other models, for example: https://docs.google.com/spreadsheets/d/...
