Electrical System Composition and Functions
1. The system is equipped with a 10-inch touchscreen display, allowing for real-time monitoring of data such as battery pack voltage, charge/discharge current, battery temperature, State of Charge (SOC), relay status, charging status (CC/CP signals), insulation monitoring, and individual cell voltages. The touchscreen enables users to view and modify BMS parameters—including alarm and protection thresholds—and simulate various system states, such as Level 1 alarms or Level 2 protection triggers. The display also features an auto-wake/sleep function to conserve energy.
2. The system includes an intelligent On-Board Charger (OBC) that communicates with the BMS via the CAN protocol. Upon connection of a charging gun, the system verifies the CC and CP signals; once the self-test is passed, the positive charging contactor closes. The OBC then performs constant-current charging based on real-time data provided by the BMS, which continuously monitors the charging process.
3. High-voltage connections within the battery pack utilize specialized high-voltage connectors. The system incorporates an interlock circuit; if the maintenance switch or any high-voltage connector is disconnected during operation, the relays are immediately triggered to cut off power, ensuring operational safety.
4. The BMS features a passive balancing circuit, which helps equalize the remaining energy across the battery cells, thereby extending the overall service life of the battery pack.
5. The top cover of the battery pack is fitted with a transparent acrylic panel (≥4mm thick), providing a clear view of the internal wiring. Each battery cell is labeled with a unique number, and all data acquisition wires are marked, allowing for an intuitive understanding of the wiring configuration.
6. A discharge load is included, controlled via a dedicated switch, to facilitate the discharging of the battery pack during training exercises.
7. The system supports AC charging; it can be connected to an AC charging gun (compliant with national standards) via an AC charging port, demonstrating the control principles of charging systems in new energy vehicles.
8. The panel is equipped with 2mm test terminals designed for a secure fit with multimeter probes. These terminals serve as test points for diagnosing faults and monitoring electrical signals—such as resistance, voltage, current, frequency, and waveforms—within the battery management system circuitry.
9. Product Components: Lithium iron phosphate (LiFePO4) battery pack, Battery Management System (BMS), intelligent On-Board Charger (OBC), DC/DC converter module, AC charging relay, main positive relay, main negative relay, pre-charge relay, pre-charge resistor, Manual Service Disconnect (MSD), Hall-effect current sensor, ignition switch, 10-inch touchscreen display, GB/T standard Mode 2 charging cable, GB/T standard AC charging inlet, and a 12V starter battery.
10. Equipped with a protective device for the main power switch.

Fault Simulation System
Includes an industrial-grade wireless remote-controlled fault simulator (supporting ≥8 channels). The remote control measures 143 × 50 × 25 mm, is powered by two AAA batteries, and features a power switch on the side.
• The remote control is equipped with numeric keys 1–8; pressing a specific key triggers a fault, while pressing the same key again clears the fault.
• The "Master Off" (Total Disconnect) key on the remote control allows for the simultaneous activation of all faults.
• The "Master On" (Total Reset) key on the remote control allows for the simultaneous clearing of all faults.
• An LED indicator at the top lights up when a key is pressed, confirming that the signal has been successfully transmitted.
