OVERVIEW
    AT6920 Pulse-Type Lithium Battery Cell Short Circuit Tester‌ is specifically designed for safety performance testing of lithium battery cells. The instrument utilizes high-voltage pulse technology (adjustable 50–2000V) to accurately detect internal short circuits, micro-shorts, and insulation defects, achieving millisecond-level testing speed。

    Equipped with a full-color LCD touchscreen supporting bilingual (Chinese/English) operation, it features built-in storage for 100 sets of waveforms with comparison functionality. Data export and remote control are enabled via multiple interfaces including USB, RS232, RS485, and LAN。

    The intelligent analysis system automatically determines OK/NG results and calculates pass rates. Widely applied in lithium battery production quality inspection and R&D testing, it serves as an efficient tool for ensuring battery safety。

    The software includes database functionality and Excel export capability, facilitating efficient remote control, data acquisition, and analysis。
FEATURES
  • Support for storing and recalling 100 sets of waveforms;
  • Export test data in CSV format via USB drive;
  • Data statistics function, automatically calculates pass rate.
