5V400A Neware Battery Test Solution LFP Prismatic Cells 10C Discharge Cycle Tester
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 .
a . Neware battery testers provide good accuracies both for voltage and current . This ensures you get the most reliable data from your tests .
b . 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 .
c . A measurement system can be accurate but not precise , precise but not accurate , neither , or both .
d . 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 .
e . 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 .
f . 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 .
