Functional Characteristics
Wide Applications: suitable for daily charge, discharge, and equalization maintenance of lithium-ion battery cells, module cells, and pack cells.
Wide Voltage Range: The 5V voltage range is suitable for cell balancing of various types of lithium battery cells.
Equalization Maintenance: supports charging equalization and discharging equalization according to the real-time cell voltage and preset target voltage.
Independent channel design: supports 26 separate channel testing and users can choose any channels to equalize, ensuring each cell will not be overcharged or over-discharged.
Current Regulation Step: 50mA, meeting equalization tests in environments with accuracy requirements.
Voltage Regulation Step: 1mV, accurately control balancing target voltage.
Voltage Clamped: constant voltage and reduces current, ensure that the voltage of the cells in the battery is infinitely close to the target voltage to improve the equalization effect.
Multiple Protections: It supports providing various test thresholds and adequate protection for different abnormal conditions during the test process; supports monitoring voltage, current, and battery temperature in real-time.
Alarm Warning: The system triggers the automatic termination of the test when an abnormal condition occurs; the LCD prompts and beep warning to assist users in proper processing.
Highly intellectualization: using an intelligent operating system, 7-inch large screen interaction, straightforward operation, and humanized UI design make maintenance work more intelligent, efficient, and accurate.
Ample Internal Memory Space: supports uninterrupted auto data storage during the test to avoid data loss when accidental power is down. The test data can be exported by USB flash drive and uploaded to the PC and generate to Excel sheet format for data analysis.
Calibration Correction: the voltage, current and temperature values measured by the device can be calibrated and corrected at any time to ensure measurement accuracy.
