1. Display Size and Interface: 10.1" Touchscreen

A 10.1-inch high-resolution touchscreen provides ample space for clear data visualization, intuitive controls, and multi-function integration. Ensure the screen uses IPS LCD or LED technology for wide viewing angles and excellent visibility in bright daylight—critical for safe driving. Touch response should be capacitive multi-touch, supporting gestures like swipe and pinch-to-zoom for easy operation. The interface must be customizable to display EV-specific data such as state of charge, power consumption, regenerative braking status, and fault alerts.

2. CAN Bus Communication Compatibility

The dashboard must support CAN protocol to communicate with the EV's core systems: including motor controller, BMS, and DC-DC converter. It should be able to receive and parse CAN messages from the electric drive system. Confirm the dashboard can be programmed or configured to match the CAN identifier formats and data structures used in your setup. Look for support of standard CAN baud rates and protocols common in EV applications.

3. Real-Time Vehicle Data Monitoring

The smart dashboard should display real-time data from the powertrain:

It should also support customizable warnings and visual/audible alerts for critical conditions.

4. Integration with EV Components

Ensure the dashboard can interact with:

• BMS for SOC, cell voltages, and temperature
• Motor Controller for RPM and torque feedback
• DC-DC Converter for 12V system status
• Vehicle Speed Sensor

This integration enables the dashboard to calculate and display estimated range, energy consumption, and driving efficiency.

5. Processing Power and Operating System

Choose a dashboard with a powerful processor and sufficient memory to handle real-time data streaming and smooth UI performance. It should run on a reliable embedded OS such as Linux, Android, or a real-time operating system. This supports future software updates, app integration, and over-the-air upgrades.

6. Environmental and Durability Standards

The dashboard must withstand harsh automotive environments. Look for:

While not requiring fully sealed enclosures like powertrain components, the dashboard should still offer dust and splash resistance, especially around bezels and connectors.

7. Connectivity and Expandability

Choose a dashboard with:

These features enhance functionality and user convenience, enabling smartphone pairing, wireless updates, data logging, and reverse camera integration.

8. Power Requirements and Wiring

The dashboard should operate on 12V DC power from the vehicle's auxiliary battery. Ensure it has reverse polarity protection, overvoltage protection, and transient suppression to withstand automotive electrical noise and load dumps.

9. User Experience and Customization

A good smart dashboard allows customizable gauge layouts, themes, and data components. It should support multiple languages and offer programmable driving modes. Integration with voice prompts or alerts can further enhance safety.

10. Reliability and Support

Choose products from reputable manufacturers with automotive-grade certifications. Ensure access to technical documentation, CAN databases, and SDKs for customization and troubleshooting.
