General Overview
The FXB-X06005 training platform is developed from a complete 2025 BYD Dolphin 420 km electric vehicle, specially modified for technical education, vocational training, and higher education applications.
The vehicle is sectioned to provide direct visibility of its main mechanical, electrical, and electronic components. The right-hand side of the body is cut away while maintaining the original component layout. The sectioned areas include the front bumper, hood, roof, rear trunk lid, and rear bumper components. The exposed sections are identified using different colors and receive anti-corrosion treatment. Transparent acrylic protective covers are installed over the high-voltage components to facilitate observation while protecting the exposed areas.
Vehicle Architecture and Systems
1. Electric Propulsion System
The training vehicle retains the original electric propulsion architecture, including its highly integrated high-voltage multi-in-one assembly. The platform enables students to study the arrangement, connections, functions, and operating parameters of the main components:
- DC-DC converter.
- High-voltage power distribution unit (PDU).
- On-board charger (OBC).
- Vehicle Control Unit (VCU).
- Electric motor controller.
- High-voltage power distribution system.
- Electric traction motor.

The upper cover of the integrated high-voltage assembly is removed and modified to provide a transparent view of its internal structure, allowing students to understand the arrangement and functions of the different modules.
2. High-Voltage Battery and Battery Management System
The platform retains the original traction battery and its electronic Battery Management System (BMS). Students can study the energy storage architecture, battery measurement circuits, and the monitoring and management functions of the battery system.
The battery management system includes one Battery Sampling and Actuation Unit (BASU), multiple Battery Information Collectors (BIC), and a dedicated battery data acquisition harness.
The battery thermal management system incorporates a heat-pump-based solution for temperature regulation.
3. Onboard Electrical and Electronic Systems
The vehicle also retains its original Cross-Domain Computing Platform, allowing students to study the control functions and interaction between the various onboard electronic systems, including:
- Air conditioning system.
- Door locking system.
- Smart key system.
- Electronic Parking Brake (EPB).
- Integrated Power Brake system (IPB).
- Electric Power Steering system (EPS).
- Gear selector.
- Instrument cluster.
- Cooling system.
- Brake master cylinder.
- Vehicle charging port.
All major components retain their original installation positions and connections, providing an accurate representation of the vehicle's functional architecture.
4. Retention of Vehicle Operating Functions
Despite its educational modifications, the vehicle retains its main operating functions. It can be powered on and off and can perform driving operations.
The chassis, front and rear track widths, and front suspension parameters remain consistent with the original vehicle configuration. The front wheels are connected to the transmission through the original drive shafts and can be driven normally when the appropriate gear is engaged.
Fault Setting and Detection Platform
5. Diagnostic and Connection Panel
The platform is equipped with a dedicated educational connection panel for testing, measurement, and diagnosis of the vehicle's various systems. It enables real-time monitoring of vehicle data, static signals, and electrical and electronic parameters without damaging the original vehicle wiring harness.
The system supports measurement and diagnosis of signals from the following components and systems:
- High-voltage multi-in-one assembly: DC-DC, PDU, OBC, VCU, and motor controller.
- High-voltage power distribution system.
- Electric motor and transmission assembly.
- Cross-domain electronic control system.
- Air conditioning, door locking, and smart key systems.
- Electronic Parking Brake (EPB).
- AC and DC charging systems.
6. Fault Simulation Systems
The connection panel integrates two complementary fault-setting systems, enabling instructors to prepare practical troubleshooting and diagnostic exercises.
Mechanical Fault-Setting System:
- At least 250 fault-setting points.
- Gold-plated U-shaped plug connections.
- Safe and reliable connection design.
- Operating area located at the front-left section of the panel.
- Internal compartment with an upward-sliding access door.
- Dedicated 2 mm jumper wires supplied for short-circuit fault simulation.
Wireless Fault-Setting System:
- FXB fault-setting software integrated into a dedicated tablet.
- At least 30 wireless fault-setting points.
- Allows instructors to prepare and conduct practical troubleshooting exercises using the tablet.
Mobile Structure and Mechanical Design
The training platform is mounted on a mobile alloy steel frame designed to provide resistance to oil, corrosion, and the demanding conditions of laboratory and workshop environments.
The frame is equipped with four casters, including two swivel wheels and two fixed wheels, allowing convenient movement. The swivel casters feature locking mechanisms to secure the platform during practical training sessions.
The casters have a minimum external diameter of 4 inches and are designed for low rolling resistance, quiet operation, and good wear resistance.
