Aging Cabinet Series Feedback Type（Double Cabinets）

Bi-directional energy flow with discharge energy feedback to grid efficiency ≥93% (DC bus efficiency) Both the middle-level machine and lower-level machine adopt 32-bit ARM chips for CAN bus communication, featuring fast data transmission speed and stable performance. The DC-AC module employs space vector modulation (SVM) technology and multiple layers of software/hardware protection mechanisms to ensure stable operation of the equipment. The DC-AC module adopts advanced PID control technology to avoid impact on battery packs during operation. The CAN 2.0 interface enables seamless integration with battery pack BMS data, providing real-time monitoring of battery pack status during both charging and discharging processes. It supports battery aging tests for both same-port and different-port batteries. The voltage detection adopts a 4-wire configuration. Integrated reverse polarity protection module to prevent battery reverse connection. LED indicators for charging/discharging status, charging/discharging curve analysis graphs, and barcode scanning functionality. It can be integrated into production lines to match production cycles, and can also be used for standalone testing.
