In general, testing battery capacity is an important step in evaluating battery performance, and different testing methods have their own advantages and disadvantages. When choosing a test method, factors such as actual needs, equipment conditions, and test accuracy requirements should be considered comprehensively.
By measuring the voltage across the battery, its remaining capacity can be preliminarily estimated. The constant current discharge method is a more accurate battery capacity test method. Connect the battery to a certain load and discharge it at a constant current until the battery voltage drops to the predetermined cut-off voltage.
Machine needed – Individual Cell Capacity testing Machine Formation – The cells received by the pack manufacturing unit could be at different levels of charge. In this step, the cells are first fully charged and then fully discharged to figure out the actual capacity of each cell.
The use of high-capacity batteries as the battery pack of electric vehicles is the current development trend. In order to better design battery packages and battery management systems and develop related battery estimation technology, the related characteristics of high capacity battery cells need to be studied in depth.
