To test DCIR: According to the different current I1, I2 under the voltage changes U1, U2 to calculate the internal resistance.
E-I1*r=U1、E-I2*r=U2:r=(U1一U2)/(I2-I1)
To avoid the acquisition point of a single collection of the rising edge of the recording point, you can select any point on the curve. When calculating the DCIR in the charge or discharge pulse step, the user can freely select any data of any step as the sampling point.
Neware Battery Testing System has professional step to setting:
You also step the DCIR by choosing the Pulse DCIR
HPPC test generally completed by Neware BTS4000 battery testing equipment. HPPC test can be completed on the battery DC resistance test.
