3. Step-by-Step Guide to Using Torque Pro with EV OBD2 PIDs

Using Torque Pro to access and interpret EV OBD2 PIDs requires careful setup and configuration. Here’s a step-by-step guide:

3.1 Setting Up Torque Pro

1. Purchase and Install Torque Pro: Download Torque Pro from the Google Play Store and install it on your Android device.
2. Acquire an OBD2 Adapter: Purchase a compatible OBD2 Bluetooth or Wi-Fi adapter. Ensure it supports the CAN bus protocol, which is essential for modern EVs.
3. Connect the Adapter: Plug the OBD2 adapter into the vehicle’s OBD2 port, typically located under the dashboard.
4. Pair the Adapter: On your Android device, go to Settings > Bluetooth (or Wi-Fi) and pair with the OBD2 adapter. The adapter may require a PIN code, often “1234” or “0000”.
5. Configure Torque Pro:
   • Open Torque Pro and go to Settings > OBD2 Adapter Settings.
   • Select the connection type (Bluetooth or Wi-Fi) and choose the paired adapter.
   • Test the connection to ensure Torque Pro can communicate with the adapter.

3.2 Adding Custom EV PIDs

Torque Pro comes with a set of standard PIDs, but for EVs, you’ll need to add custom PIDs specific to your vehicle model.

1. Obtain the Correct PID List: Acquire a list of EV-specific PIDs for your vehicle. These lists can often be found on EV forums, enthusiast websites, or from CAR-DIAGNOSTIC-TOOL.EDU.VN.
2. Add Custom PIDs:
   • In Torque Pro, go to Settings > Manage extra PIDs/Sensors > Add predefined set.
   • If you have a .csv file containing the PIDs, import it. Otherwise, manually add each PID by selecting “Add custom PID”.
   • Enter the PID information, including the long name, short name, minimum value, maximum value, scale factor, unit, and equation. The equation is crucial for converting the raw data into a meaningful value.
3. Test the PIDs: After adding the PIDs, test them to ensure they are returning valid data. Start the vehicle and monitor the PID values in real-time.

For example, to add a PID for battery voltage, you might use the following settings:

• PID: 220435
• Long Name: Battery Voltage
• Short Name: Bat. Voltage
• Min Value: 0
• Max Value: 500
• Scale Factor: 0.1
• Unit: V
• Equation: (A*256+B)/10

In this example, A and B represent the two bytes of data returned by the PID. The equation multiplies the first byte by 256, adds the second byte, and then divides the result by 10 to obtain the voltage in volts.

3.3 Creating Custom Dashboards

Once you’ve added the custom PIDs, you can create custom dashboards to display the data in a way that’s easy to read and understand.

1. Create a New Display:
   • On the main screen of Torque Pro, long-press on an empty space and select “Add Display”.
   • Choose the type of display you want (e.g., gauge, graph, digital display).
2. Select the PID:
   • Select the PID you want to display on the gauge.
   • Configure the display settings, such as the minimum and maximum values, colors, and labels.
3. Arrange the Displays: Arrange the displays on the dashboard to create a layout that suits your needs. You can add multiple dashboards and switch between them as needed.

By following these steps, you can set up Torque Pro to effectively monitor and diagnose your EV. CAR-DIAGNOSTIC-TOOL.EDU.VN offers detailed video tutorials and guides to further assist you in this process.

4.2 Temperature Conversion Formulas

Temperature PIDs typically return values in Celsius or Fahrenheit. Common formulas include:

• Celsius: Temperature (°C) = Raw Value - Offset
  • Example: Temperature = A - 40 where A is the raw value and 40 is the offset.
• Fahrenheit: Temperature (°F) = (Raw Value * 9/5) + 32
  • Example: Temperature = (A * 9/5) + 32 where A is the raw value.
• Kelvin to Celsius: Temperature (°C) = Raw Value - 273.15
  • Example: Temperature = A - 273.15 where A is the raw value in Kelvin.

4.3 Current Conversion Formulas

Current PIDs provide information about the flow of electricity into or out of the battery or motor. Common formulas include:

• Scaling with Offset: Current = (Raw Value * Scale Factor) + Offset
  • Example: Current = (A * 0.01) - 5 where A is the raw value, 0.01 is the scale factor, and -5 is the offset.
• Two-Byte Scaling: Current = ((A * 256) + B) / Scaling Factor
  • Example: Current = ((A * 256) + B) / 10 where A is the first byte, B is the second byte, and 10 is the scaling factor.

4.4 State of Charge (SOC) Formulas

State of Charge (SOC) PIDs indicate the remaining capacity of the battery as a percentage. Common formulas include:

• Percentage: SOC = Raw Value * Scale Factor
  • Example: SOC = A * 0.5 where A is the raw value and 0.5 is the scale factor.
• Scaling with Offset: SOC = (Raw Value * Scale Factor) + Offset
  • Example: SOC = (A * 0.1) + 0 where A is the raw value, 0.1 is the scale factor, and 0 is the offset.

4.5 Torque and Speed Formulas

For motor performance analysis, torque and speed PIDs are essential. Common formulas include:

• Torque: Torque = (Raw Value * Scale Factor) - Offset
