Good morning,
I'm using the 40Z50-561 board and EV2400 for characterization of Li-Ion batteries. I'm currently testing a Li-Ion battery (ANSMANN 18650 1S1P 1INR19/66, 3500mAh) but I can't test it without a chemID. I read in other conversations in this forum that the Li-Ion battery manual procedure for the Data Log file and the Configuration file generation is the following:
1. Test is performed at room temperature. If the cell was at a different temperature , let the cell relax for two hours at room temperature prior to the test.
2. Charge using CC or CV charging to full using taper current. (For example, C/100.) Use nominal CC charge rate and CV voltage. If another charging method is specified by the cell maker, use that method.
3. Let the battery relax for two hours to reach full equilibrium open circuit voltage (OCV).
4. Discharge the battery at C/10 rate until the minimal voltage (as specified by the cell manufacturer) is reached.
5. Let the battery relax for five hours to reach full equilibrium OCV.
So, in order to obtain a correct result, the procedure seems to take a long time (about 20hrs).
The question is: is there an alternative automatic method in order to obtain the correct chemID for the battery under test?
Thanks in advance
