4CH Neware Battery Testing System DCIR and Discharge Capacity Tester

 

A . Software Feature

1 , Windows-based software interface for easy operation .

2 , Uses standard SQL data - base management .

3 , Real - time monitoring windows and integrated graph / data windows can set various working modes for measuring capacity and cycle life of all types of rechargeable batteries , such as:constant current discharge , constant current charge , constant voltage charge , rest , as well as voltage , current , time , capability , negative voltage slope , and other limit conditions .

4 , The user can define the curve by different types such as voltage - time curve , current - time curve , capacity - voltage curve ,

loop times - charge / discharge capacity curve , loop times - charge / discharge efficiency curve , etc . to make curves be compared both by visually and statistically .

5 , Provide timely instructions , warnings, and intelligent support .

6 , Compliance CE Certified .

7 . Neware battery testers provide good accuracies both for voltage and current . This ensures you get the most reliable data from your tests .

8 . A measurement system can be accurate but not precise , precise but not accurate , neither , or both .

 

9 . Neware battery testers provide good prrecision meanwhile . To get an overall performance of a measurement system , Measurement system analysis MSA is usually introduced for the study .

 

B . DCIR - Direct Current Internal Resistance

1 . Direct current internal resistance of batteries is the r esistance of current flowing through the battery , with the standard unit of measurement called the ohm .

2 . The value of DCIR is not fixed , and varies depending on multiple factors , such as battery materials , electrolyte concentration , temperature , and depth of discharge .

3 . The variation of DCIR has a great influence on battery discharge performance , especially for high power batteries . In general , the better the battery , the lower the internal resistance .

4 . Therefore , most battery manufacturers identify DCIR as a key indicator to evaluate battery quality . The method of DCIR measurement is to inject high current into the anodeand cathode of the battery in a short period , and then record the changes of battery voltage and charge / discharge current .

5 . To calculate DCIR by Ohm Law , voltage variation is divided by current variation .
