DCIR TESTER

Through the integration of PC computer, PLC and hardware, SEMCO HYNN DCIR tester can accurately measure the DC internal resistance and open circuit voltage, realizing the perfect combination with the automation. The DCIR tester can not only test for the important parameters of battery measurement but also fulfill the development of industrial automation and technology.

  • Test the DC internal resistance of batteries

  • Test the open circuit voltage of electric cores

  • Shock test of electric core diaphragm (screen out electric cores with defective diaphragms)

 

Method:

  • DC internal resistance in discharging

a1. 80 A constant current, discharge for 10s [take voltage Vd0 in the 9th second]

a2. 150A constant current, discharge for 10s [take voltage Vd1 in the 1st second]

Stabilize for 20s

  • DC resistance in charging

a1. 80A constant current, charging for 10s [take voltage Vc0 in the 9th second]

a2. 150A constant current, charging 10s [take voltage Vc1 in the 1st second]
