This high-performance battery test power system is engineered for demanding laboratory and production environments that require precise control of high current and medium voltage. Operating from AC380V±15%, 50/60Hz, it delivers up to 35.3 kW input power with an impressive power factor ≥99% and THDi ≤5% at full load, minimizing impact on the facility power network. The system uses a three-phase five-wire input and integrates comprehensive power input protection (anti-surge, over/under voltage, over/under frequency, phase loss, etc.), ensuring safe and stable operation.

On the DC side, it supports charge voltages from 0V to 100V and discharge from 3V to 100V, with voltage accuracy ±0.02% of FS and 24-bit resolution for fine control and precise measurement. The current range 1.5A–300A with ±0.05% FS accuracy and 24-bit resolution makes it ideal for testing a wide range of power battery modules and packs. A CV cut-off current of 300 mA enables accurate transition at the end of constant voltage charging. Using MOSFET power modules and four-wire sampling (separate ports for charge and discharge), the system ensures low noise (≤65 dB), high stability, and up to 90% maximum overall efficiency, making it an excellent choice for rigorous battery R&D and production testing lines.
