Vehicle System Architecture¶
The Optimal EV vehicle architecture consists of several core components that communicate through CAN networks and cloud services.
Customer View¶
Customers mainly interact with the dashboard and reports.
The Service Box collects vehicle data and securely sends it to the cloud.
Main Components¶
| Component | Description |
|---|---|
| Service Box | Embedded Linux device that logs CAN data and communicates with the cloud |
| Vehicle Control Unit (VCU) | Main vehicle logic controller |
| Battery Management System (BMS) | Monitors battery voltage, current, and temperature |
| Cloud Platform | Stores telemetry and provides dashboards |
Data Flow¶
- Vehicle ECUs communicate through CAN.
- Service Box listens and logs CAN traffic.
- Signals are parsed and sent to MQTT.
- Data is stored in the cloud database.
- Dashboard displays telemetry and diagnostics.
