APPLICATION INDEPENDENT MAP-BASED CYCLE LIFE TESTING OF BATTERY CELLS

摘要

A method and system for application independent map-based cycle life testing of battery cells is provided. A target depth of discharge (DOD) and a charge/discharge current level is selected for the battery test. The battery is discharged to the target DOD. The battery is cycled within the DOD range one or more times, wherein the cycling comprises a charge pulse and a discharge pulse at the selected current levels. A reference performance test (RPT) is performed on the battery, wherein the RPT comprises a static capacity test and a dynamic power test. The cycling and RPT testing are repeated until an end of test condition is detected.
