DCIR - Direct Current Internal Resistance

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

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

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 .

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