Isabellenhütte IVT-S shunts available
I ordered the Isabellenhütte IVT-S shunts directly from the manufacturer. Got a much better pricing and have a few of them available if there is interest. Won't post the price publicly so PM me if you are interested.

Many thanks for organising this, I posted to the course WhatsApp groups and it generated a lot of interest

Jaanus, I can't see a PM/DM option, this may be because I'm quite new to OpenInverter forum.
Would you be so kind as to initiate a PM with me, please?

Is this the shunt used in The SuperYacht BMW? If so id be interested in one.

Re: Isabellenhütte IVT-S shunts available
Currently installed in BEXUS (aka SuperYacht), Grey Goose, and ICE Breaker. Will be standard fit in all our cars going forward because it has some very advanced features at an incredible price point

Re: Isabellenhütte IVT-S shunts available
Has anyone here got the DBC file for them? There is only mention of it being available but no reference where.
If no one knows then I’ll ask them tomorrow.

Re: Isabellenhütte IVT-S shunts available
Updates on the shunts. The 1000A shunts are all gone now. There has been interest in getting more of those so should I get total interest for about 8 more of them I will put in an order (they come in lots of 12).
Meanwhile I have managed to source new and unused but an older model of the 500A continuous (730A 5min, 860A 30s, 1000A 10s, 2700A 1s, 6000A 200ms) rated shunts. Hit me in private for the pricing. Exact model IVT-500-U3-TOI-CAN2-12.
Also I am trying out something new. I have added 5% to the prices that I will send as direct donations split evenly between johu and Jack Bauer.
Please let me know if you don't want to do that and I will knock it off the cost. Noone will be judged.

Re: Isabellenhütte IVT-S shunts available
Thanks again. I suppose if using Gen 2 inverter, the voltage from boost converter to Mg2 will not be monitored by Isa, so 600vdc is well within spec for Dc bus(= hv battery) ?

I put a new order in for the 1000A shunts, anyone who has not given me their interest in the past few days please let me know if you want one.

Re: Isabellenhütte IVT-S shunts available
Does this work with tom's simp BMS? Are 1000A correct for a Tesla LDU and a Model3 battery with fast charge?
If so, i would take one!

The standard ISA IVT-S canbus messages should work, or atleast the messages from my shunt did.muehlpower wrote: ↑Tue Apr 28, 2020 7:39 pm Does this work with tom's simp BMS? Are 1000A correct for a Tesla LDU and a Model3 battery with fast charge?

Re: Isabellenhütte IVT-S shunts available
Just a quickie, My IVT-S just arrived and I’ve rigged it up to DM’s Leaf VCU board running V1.5 firmware.
http://media3.ev-tv.me/ISA.zip
I tried editing the file by replacing “ISA2.h“ with “ISA.h“ Within the code but I might be using the wrong file.
Does anyone have a correct version of ISA.h to work with the IVT-S shunt please?
The board communicates with the ISA Shunt through the ISA.h file. The only version I could find of this file is from EVTV But it had some issues with it:http://media3.ev-tv.me/ISA.zip

Re: Isabellenhütte IVT-S shunts available
Damien kindly sent me the following information recently... I haven't used this myself but suggest as a group of ISA shunt users you pick it up, run with it, and update the wikijames@N52E01 wrote: ↑Sat Jun 06, 2020 3:22 pm Does anyone have a correct version of ISA.h to work with the IVT-S shunt please?
From the factory the isa shunt does not output many parameters and not in a format that is readable to the library. It defaults to big endian and the arduino is written in little endian. Fortunately, friend Jack at EVTV took care of that and installed a configuration option in the library. To use the shunt the following steps are required;
1) Load up the demo sketch on a due with a can transciever or any of the VCUs.
2) from the menu choose the initialise option.
3) Reboot and normal data should be pumped out.

Some comments on the photo;james@N52E01 wrote: ↑Sat Jun 06, 2020 3:22 pm Just a quickie, My IVT-S just arrived and I’ve rigged it up
(1) you have a red twisted pair cable going to the shunt voltage measurement pins. Can you confirm these wires are shorted together not from different voltages?
(2) It looks like you have a CAN termination resister installed. Is this on the two centre or two outer pins? It's not clear from the photo.
(3) Can you confirm you have the ISA Shunt without internal CAN termination? I don't know what part was supplied to you.
** recommend you test at low voltage and with current limiting resister to begin

Re: Isabellenhütte IVT-S shunts available
1) yes the voltage measurement wires are twisted just to keep them out of the way but they both go to the same point as per the wiring diagram.
2) The 120R CAN Termination resistor is across pins b & c (the middle 2) which I believe are CANLo and CANHi according to the manual.
3) Yes this is a non-terminated CAN shunt. The model number on the shunt is IVT-S-1K-U3-CAN2-12/24.
The CAN2 means non-terminated according to the manual. Good call on the current limiting resistor, I’ve gone for a 12v bulb.
I believe they are internally shorted so I’ve just used 2 for redundancy.2) The 120R CAN Termination resistor is across pins b & c (the middle 2) which I believe are CANLo and CANHi according to the manual.

Re: Isabellenhütte IVT-S shunts available
Sorry Kevin, I may have stumbled at the first hurdle. To load up the demo sketch - ISAScale_Test_dm2.ino - the script contains the same reference as the VCU code:Kevin Sharpe wrote: ↑Sat Jun 06, 2020 3:37 pm1) Load up the demo sketch on a due with a can transciever or any of the VCUs....james@N52E01 wrote: ↑Sat Jun 06, 2020 3:22 pm Does anyone have a correct version of ISA.h to work with the IVT-S shunt please?
....
ISA.zip
ISAScaleTest_dm2.ino.zip
#include <ISA.h>
The ISA.h file included in Jack’s ISA.zip opens with these two lines of code:
#ifndef ISA2_h
#define ISA2_h
There is no ISA2.h in Jack’s zip file and I can’t find it anywhere. Fiachra and I have previously gotten around this issue by changing these references to:
#ifndef ISA_h
#define ISA_h
This has allowed us to pass the verification check and flash the VCU code onto the boards. Is this ISA2.h file needed or do we need a different version of ISA.h?

Re: Isabellenhütte IVT-S shunts available
What you really need is some software expertise to work through these issues (renaming files so that the source compiles does not mean it's going to work).
Can anyone who purchased a shunt help get ISAScale_Test_dm2.ino working?

Re: Isabellenhütte IVT-S shunts available
The library and demo code I sent Kevin, which he linked above, compiles, loads and works. I have 5 isa shunts in cars working with this now and the last time I had any formal software training we were using wire wrap boards!
#ifndef ISA2_h
What could that mean? hmmm....if ..not...defined.....ISA2_h...
#define ISA2_h
Define it as ...ISA2_h
Its a friggin trick question! in english it would read as "If my name is not Damien, Make my name Damien"

Re: Isabellenhütte IVT-S shunts available
Thanks JB, sorry for wasting your time there.
As Kevin say, the demo file loads up and runs fine on the VCU board. A quick look at the code shows that the “i” command through the serial monitor should initialise the shunt.

Re: Isabellenhütte IVT-S shunts available
Is ISAScale_Test_dm2.ino for a Due board only?
I've got my Isabellenhütte working great with an Uno + cheap CanBUS shield. I will post details on the wiki.
I don't have a Due (yet).

Re: Isabellenhütte IVT-S shunts available
I've added an article to the wiki with some code that pulls data out of an IVT-S over CAN bus using an Arduino Uno.
https://openinverter.org/wiki/Getting_s ... bus_shield
I'll add something similar for a Due when I have the necessary transceiver...
