Torque Digital Touch Display
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. Due to the flexible OBD2 support of the Orion BMS, Torque works cleanly with the Orion BMS out of the box and many Orion BMS customers use this display.

- Integrates seamlessly with the Orion BMS for displaying parameters and viewing & clearing error codes.
- Powerful touch-enabled interface provides easy-to-use display.
- Entire interface is customizable (gauge type, gauge location, gauge look and feel, etc).
- Works on smartphones, tablets and other Android enabled devices (device MUST have USB host or Bluetooth capabilities depending on which adapter is used).
- Can be used to do data logging as well as live web-based performance streaming.

Required items to use Torque with the Orion BMS
1. A Bluetooth Touch Screen Display (7 inch $197, 8 inch $238, 10 inch $287 all options come with a 2 year Warranty, Industrial Strength Velcro, 5v 1A Cig Socket Charger, and 120V 15A wall charger/plug). Install your display in a location shaded from the sun for both longevity of use and screen readability.
2. The Torque App from Google Play. ($4.95 download it here)
General connection diagram
One of the CAN interfaces on the Orion BMS must be connected to the OBD2 connector that the OBD2 to Bluetooth (or USB) adapter is plugged into. A minimum of 5 wires must be connected to the OBD2 connector to operate:
OBD2 Pin #
6 – CAN High
Orion BMS CAN1 or CAN2 High
14 – CAN Low
Orion BMS CAN1 or CAN2 Low
4 – Chassis Ground
5 – Signal Ground
16 – Battery Voltage
+12V (power for adapter)
Full OBD2 Connector Pinout: http://en.wikipedia.org/wiki/On-board_diagnostics.
The CAN network requires exactly 2 each 120 ohm termination resistors at each physical end of the CAN network.
Note: The baud-rate of the connected Orion BMS CANBUS interface must be either 250 Kbps or 500 Kbps to conform to OBD2 standards. This setting is available under “Communications Settings” in the BMS Profile section of the BMS utility.
Note: The OBD2 ECU ID may be changed from the default value if this ECU ID is integrated into a vehicle that already uses this ECU ID. It is important that each ECU in the vehicle have a unique ECU ID. This setting is available under “Communications Settings” in the BMS Profile section of the utility.
The adapter setup portion of Torque is dependent on what OBD2 adapter is being used. Please consult the official Torque documentation / support forum for assistance getting the adapter interface configured.
The next portion is adding the Orion BMS PIDs (viewable parameters such as battery voltage and current) to Torque. There are two different ways to do this.
Method 1 (Manual Entry – For Novice Users):
1. Download the following PDF file: Orion BMS Torque Extended PIDs (PDF)
2. Open Torque and go to “Settings” (usually by pressing the bottom left key [looks like an upside down box] on the phone / tablet and then selecting Settings).
3. Scroll down in the settings list and click “Manage extra PIDs/Sensors”
4. Press the Menu button again (looks like upside down box) and press “Add custom PID”
5. Press “OK” to agree.
6. Fill out the appropriate information from the List of OrionBMS Torque PIDs, starting with the first PID (or whichever ones are wanted / needed).
7. Repeat steps 3 – 5 for all PIDs wanted / needed.
8. Return to the Torque main screen by hitting the Back button (backwards arrow) several times.
9. Press the “Realtime Information” button on the main screen to go to the gauges screen.
10. Long press (press and hold) any area on the screen to bring up a list of options about adding / editing existing gauges. When adding a gauge, the PIDs added manually should be selectable as options.
11. The gauges should be updating regularly at this point.
Method 2 (Automatic Entry – For Advanced Users):
Torque provides a secondary method for bulk loading multiple PIDs into memory by reading them in from a file.
1. Download the following file to the Android device: Orion BMS Torque Extended PIDs (CSV)
2. Install a File Manager application (Astro File Manager is commonly used).
3. Open the File Manager and navigate to the home Torque folder (commonly this is ‘/mnt/sdcard/.torque’ OR ‘/.torque’.
4. Copy the file downloaded above (“orionbms_pids.csv”) in to the ‘extendedpids’ folder (which should already exist).
5. Exit the file manager and re-open Torque.
6. Go to “Settings” and then scroll down to “Manage extra PIDs/Sensors”
7. Press the Menu button on the device (looks like upside down box) and then press “Add predefined set”
8. Select “orionbms_pids” to add them as a predefined PID list.
9. Return to the Torque main screen by hitting the Back button (backwards arrow) several times.
10. Press the “Realtime Information” button on the main screen to go to the gauges screen.
11. Long press (press and hold) any area on the screen to bring up a list of options about adding / editing existing gauges. When adding a gauge, the PIDs added manually should be selectable as options.
12. The gauges should be updating regularly at this point.
