Neware 2 Channel Battery Grading System Battery Condition Simulation Tester
Battery researchers and scientists , battery manufactures , importers and exporters , you can always choose the most appropriate Neware battery testers for battery quality check , battery performance tests , battery material research , and battery mass production lines .
Using dynamic power or current waveform to simulate electric vehicle driving road . Simulate the electric vehicle driving road conditions through the dynamic power or current waveform .
CT-4000 mainly applies for institutions , colleges and universities and EV battery manufacturers .
Simulation - the Way You Look into Reality
You know battery capacity at at constant current , or power , or load . But the reality is that no the energy is drawn by a constant variable . Your capacity or energy tested under constant conditions can only be a general one , and the cycle life tested such regime can also be largely deviated from reality . To have a better master of reality, simulation is introduced . GSM pulse is of such kind for phone batteries . for EV batteries , Drive Cycle Simulation is used .
If you have recovery battery pack , like Toyota Prius battery pack , generally, each piece has 6 single Ni - MH cell , then several pieces batteries assembed in one pack , and you need to check each single cell for capacity , cyclie life , resistance , etc . Then assemble the battery cell after sorting by capacity , resistance . You will get the new battery pack . And last you will test the battery pack to check the real capacity and other function parameter .
