I am converting an old 70s Chevy truck to electric so it has no CAN Bus architecture nor do I want to introduce any beyond what it takes to drive the electric motor type of thing.

I plan on using the Isabellenhütte IVT-S current sensor and would like to know if any of you have done so with what I would call standard analog or even digital gauges that we can mount in the dash of the car. I see on the Menu of the program in it's tutorial that there is an option for J1939 which seems to be some sort of interface standard no?

I am just looking to display the basics, Volts, Amps, Watts, and maybe some other stuffs as I dive deeper into what this brilliant German hunk of metal can do.

any help and links especially to some compatible plug and pray gauges is greatly appreciated

well of course since I am learning about this GizmoTron I am going to force everyone to suffer with me, ha ha, so here is a list of ...

this is just an excerpt from the manual on how to decipher the Fahrvergnügen part numbers

So I contacted Isabellenhutte USA technical support and got a kind reply from Randy who basically pointed me at AEM EV line of products, so I checked them out and first I didn't know they had a dedicated line of EV products but maybe I am just too dumb to find a simple gauge or set of gauges on there cause it seems like they are trying to sell you a $1,000 digital console

 

[gregski]

bro, what is it that you are actually looking for? well sometihng like this HiLetgo Digital Multimeter AC 80-260V 100A PZEM-061 LCD Display Digital Current Voltage Power Energy Multimeter Ammeter Voltmeter with Current Transformer CT but on steroids meaning something that can handle 360 volts and 1,000 amps

hoping to find something plug and play off the shelf that I don't have to geek out on a breadboard to roll my own

 

[gregski]

what I ordered/bought on eBay - ONE Isabellenhutte thingie like this one

 

[gregski]

... and what I got - The Struggle is Real ! ha ha

 

[gregski]

this is a wonderful opportunity to practice our Isabellenhutte part number decoding

IVT-S-1K-U0-I-CAN1-12/24

so let's breakdown that bad boy

IVT-S-1K-U0-I-CAN1-12/24 - ok that's just the product group and I think they all are IVT-S

IVT-S-1K-U0-I-CAN1-12/24 - moving along 1K means 1,000 amps so far so good

IVT-S-1K-U0-I-CAN1-12/24 - ah this is where things fall apart for us, U0 means there are zero voltage ports across the top, those three white plugs are missing

IVT-S-1K-U0-I-CAN1-12/24 I have no idea what this means somethign to do with the material they are made out of and they all are I

IVT-S-1K-U0-I-CAN1-12/24 this means there is only one white port on the bottom for CAN Bus, I actually prefer a single port rather than two (CAN2) because we don't need to terminate the second one with a hockey resistor

IVT-S-1K-U0-I-CAN1-12/24 and this is just what input power these things can run on and I think they all are 12 volt 24 volt combo units, please correct me if I am wrong

 

[oudevolvo]

I = galvanic isolation
CAN1 also implies it is terminated
12/24 is indeed allowing both input voltages

 

[gregski]

Perfect, thank you, do you have any Isabellenhutteing experience you would like to share?

 

[gregski]

so here are the four things you need just to talk to this thing

1. CAN USB Adapter (PCAN-USB) with Isolation (GC-CAN-USB-ISO) - $275

2. Grid Connect GC-CAN-TERM-GC CAN Terminator

3. Chanzon 12V 2.5A 30W AC DC Power Supply Adapter

4. Anmbest 2PCS DB9 Solderless RS232 D-SUB Serial to 9-pin Port Terminal Male Adapter

 

[gregski]

well, according to the OpenInvert.org Wiki "You can talk to CAN bus devices relatively cheaply using [something called] an Arduino Uno."

You will need the following:

• An Arduino Uno R3 board
• An MCP2515-based Arduino CAN shield
• Two 120 ohm resistors

so we went out and got us an Arduino Uno board thingie, $15 bones on AMAZON

this thing is tiny (that or I have huge hands)

 

[gregski]

alright, now what?

Configure your Arduino IDE
Download and install the Arduino IDE on your computer

What's an IDE, well it stands for Integrated Development Environment, essentially a text editor like Notepad on steroids and a compiler a special program that turns human readable code into ones and zeros so that machines understand it.


Connect your Arduino board with a USB cable
Tools -> Port make sure your Arduino board is selected
File -> Examples -> 01.Basics -> Blink
Sketch -> Upload
Hopefully you have a blinking light on your Arduino board. This means your IDE is working.

 

[gregski]

OK, we got the little Arduino brain board, we installed the software for it, we also got an Isabellenhütte IVT-S current sensor shunt thingie, but how do we get them to talk to each other?

 

[gregski]

and sometimes I just like to remind myself why we are doing this

I mean check out this little outfit called VeeThree and their CAN Bus displays page

Aren't these gauges sexy? We can get our electric motor RPM using CAN Bus how cool would that be?

The 3″ CAN bus display features a round color PCAP touch LCD. The R3 is designed as an OEM (Original Equipment Manufacturer) product, and is not available direct to end users.

Or a multi function one like this

The C3 CAN bus display, formerly the CANvu 355/Veecan 320, is a second generation compact color display from Veethree. It is designed as an OEM (Original Equipment Manufacturer) product, and is not available direct to end users.

 

[gregski]

wait, EV West may have just what we need

TBS Expert Pro Battery Monitor - For Lithium Packs up to 350V

The Expert Pro Battery Monitor selectively displays voltage, charge and discharge current, consumed amp hours, remaining battery capacity and the time remaining of your battery bank.

$269

Ah man so close, but it only goes up to 350 volts, but check out their YouTube TBS Expert Pro Battery Monitor Quick Setup Guide | EV Show video to get an idea what we're trying to achieve, as it is very similar.

well aint that special!

 

[gregski]

so I am getting a bit ahead of myself here, but I am so excited to find these blank bezels for my truck, gives me endless possibilities

first here is what the stock OEM bezel looks like with all its round holes

and here are the blanks

with these I am not restricted to round gauges, which means I can use the rectangular Nextion displays, awesome!

 

[gregski]

alright our Duplo style learning continues...

 

[gregski]

so we got our next puzzle piece in terms of the hardware needed to connect to and talk to our current sensor, this being the CAN Bus shield (pronounced CAN Bus "adapter") this adapter is actually a tranceiver, say what?

(TRANSmitter reCEIVER) An electronic device or circuit that transmits and receives analog or digital signals, either wired or wireless.
