1. Fully Integrated Power Architecture
Feature: The AC-DC conversion (PFC rectification) and DC-DC four‑quadrant conversion are highly integrated into a single module. The input connects directly to the AC grid, while the output connects directly to the battery, achieving an “All-in-One” compact architecture.

2. True Four‑Quadrant Integrated Source‑Load Operation
Feature: The DC-DC stage operates in four‑quadrant mode, allowing seamless transition between sourcing positive/negative power (charging) and sinking positive/negative power (discharging) without mode switching. This enables precise emulation of various real‑world battery operating conditions.

3. High‑Frequency PWM Technology and Efficient Thermal Management
Feature: Utilising advanced silicon‑based (IGBT) or wide‑bandgap semiconductor (SiC, GaN) technologies, the module operates at high switching frequencies, enabling smaller magnetic components (inductors, transformers) and higher efficiency. The module is typically designed with forced air‑cooling or liquid‑cooling to ensure stable operation under high power density.

4. Modularity with Independent Channel Design
Feature: A standard chassis integrates multiple (e.g., 8, 12, or 16) independent test channels. Each channel has its own CPU, power circuitry, and measurement unit, delivering a true “one channel, one world” capability.

5. High‑Precision Measurement and Intelligent Battery Management
Measurement Accuracy: Voltage measurement accuracy typically exceeds ±0.05% of reading, and current accuracy exceeds ±0.1% of reading – providing the foundation for accurate capacity and internal resistance estimation.
