DCIR test operation in BTSDA

DCIR is a key parameter to the battery performance. To calculate DCIR, there should be 2 voltage values and 2 current values. DCIR or d.c. resistance is another key parameter to know a battery's quality ( self-discharge, power characteristic, state of health). DCIR test is usually brought out in short time. So tester's capability is critical to the testing result.

If you need to perform DCIR test with your batteries, Neware BTS4000 and BTS9000 are recommended for you.

In BTSDA, you can select record rows from the data area directly to calculate DCIR, or launch DCIR calculator by clicking the DCIR tool on the tool bar(the last icon on the main toolbar of BTSDA) or the command on the right click menu of the data area. 

You can choose Step DCIR or Pulse DCIR to load the targeted data to calculate DCIR. If you click Step DCIR, there will be options provided to enable you manage what step groups and the exact records be accounted as DCIR raw data. HPPC test from FreedomCAR manual has a DCIR algorithm which draws data from the last point of rest and the data from the last point of the 10 seconds pulse – discharge or regen. Now we set the step groups and data select methods. Click OK will show the calculation result in the data grid, you can copy or export the result you get.
