High Precision Multi-current Range Battery Test System, M340A & G340A

The multi-current range battery test systems M340A and G340A are designed for precision battery charge/discharge test, coulombic efficiency (current efficiency) test and supercapacitor test. Voltage and current test accuracy go down to 0.01% of the selected range. The sampling rate can go as high as to 0.01S (100Hz) with minimum pulse interval of 2mS.

  • Support half cell, three-electrode cell (with reference electrode) in the voltage range of 0~5V, the current range of 100uA to 5A
  • High rate charge and discharge tests. with 100C (0.6min) charge/discharge, the inaccuracy of capacity test is less than 0.1%
  • Pulse test with minimum of 2mS
  • Full measurement records of voltage, current, coulombic efficiency, capacitance, internal resistance (DCIR) and more for energy storage materials research
  • Integrated UPS (uninterruptible power supply) and data storage to prevent data loss during a power failure, network problems or other unexpected circumstances
