1. CAN Bus Integration is Essential

At the heart of any EV conversion is communication between components. The electric drive system relies on CAN-based communication protocols to transmit data from the motor, controller, and various sensors. Your smart dashboard must support CAN bus input to read real-time data such as motor RPM, torque output, battery voltage, and system efficiency. Without CAN support, the dashboard is merely a decorative screen rather than a diagnostic and control center.

Ensure the dashboard can parse standard CAN messages and, ideally, supports custom DBC file loading so you can map signals from your specific motor controller to accurately display parameters like power, current, and fault codes.

2. Screen Size and Installation Compatibility

A 10.1-inch touchscreen strikes an excellent balance between visibility and installation fit within the Wuling Journey's dashboard space. Verify its physical dimensions and mounting depth match your original dashboard space. Look for units with flush or bezel designs to ensure seamless integration without blocking air vents or physical buttons. Units with high protection rating enclosures are preferable to match the powertrain's dust and water resistance.

3. Processing Power and Operating System

Choose a dashboard with sufficient processing power and memory for smooth operation. It should run a flexible operating system—such as Android or Real-Time OS—to support application integration (navigation, media, vehicle diagnostics). Android-based systems allow installation of EV-specific apps or custom CAN readers via OBD2-CAN adapters.

4. Display Quality and Visibility

Choose IPS LCD or OLED screens with high brightness for daytime visibility. Touch response should be灵敏, even with gloves. Anti-glare coating and wide viewing angles ensure readability from different seating positions.

5. Connectivity and Expandability

The ideal smart dashboard should offer:

This ensures the dashboard can evolve with future upgrades, including reverse camera integration and ADAS inputs if needed.

6. Customization and User Interface

Look for dashboards allowing custom gauge layouts—displaying motor RPM, battery state of charge, regenerative braking levels, and temperature readings from the liquid cooling system. Some advanced models support programmable warnings based on CAN data.

7. Power Supply and Voltage Compatibility

The dashboard must operate reliably on 12V DC power from the vehicle's low-voltage system. Ensure it supports a wide input voltage range to handle fluctuations during regenerative braking or cold starts. Low-power standby modes help preserve the 12V battery when the vehicle is off.

8. Reliability and Build Quality

To match the MPV's long design life, the dashboard should be manufactured with automotive-grade components capable of withstanding vibration, extreme temperature ranges, and EMI. Avoid consumer-grade tablets not designed for automotive applications.

9. Software Updates and Support

Choose brands offering regular firmware updates, technical documentation, and developer support. Open-source platforms or those offering SDKs allow deeper customization for EV conversion enthusiasts.

10. Safety and Regulatory Compliance

Ensure the dashboard meets automotive safety standards and doesn't distract the driver. Avoid overly complex interfaces or excessive animations while driving.
