Setting up Torque to show BMS data on the Ioniq EV

[JejuSoul]

------------------------------------------------------------

Updated codes are maintained on github - https://github.com/JejuSoul/OBD-PIDs-fo ... Ioniq%20EV
I will no longer update here, so am removing the old codes.

------------------------------------------------------------

Torque is an application for Android tablets and smartphones that interfaces with OBD2 enabled devices (via Bluetooth or USB) and provides visual feedback in the form of gauges and digital readouts of the various parameters and values provided.
Torque is normally used with ICE cars but by adding new parameters can be used by the Ioniq Electric EV.
The advantage of Torque is that it is really flexible in graphing and displaying data.
Many of the codes are identical to those found for the Kia S0ul EV here -

Example of Torque Screen showing Ioniq EV BMS data.


The BMS is the Battery Management System. When requested this outputs data from the battery to the OBD2 interface.

The codes for the BMS are on github

Testing and feedback is important, please create an issue on the github page if you find a problem.

The Soul EV has a battery by SK Innovation.
It has 192 polymer pouch type cells, they are laid out in a series string of 96 sets of 2 parallel cells.

The IONIQ EV has a battery by LG Chem.
It has 192 polymer pouch type cells laid out in a series string of 96 sets of 2 parallel cells.

The Torque Pro codes to measure the cell voltages for these two cars are identical.
This is somewhat surprising since the physical layout of the cells into modules is not the same.

Aren't EV's known for having great tongue?

Hey,

Thanks for the great post.
I'm expecting arrival of my Ioniq Electric on Monday coming, so was just wondering if you could tell me where the OBD2 port is on the Ioniq Electric?

Just building out some plans at the moment for datalogging and analysis.

thanks!

Hey,

I'm over in Ireland, the went on sale here end of 2016.
I have some plans to build a datalogger with a Rasp Pi for the car.

I'm curious as to whether or not the OBD2 exists, and if yes, if it can query the BMS, and if yes, if it can do so while the car is charging. this way I could build my own app to find out the state of charge while away from the vehicle. Bloody annoying that Hyundai have no app themselves..

Gilby.
