Reference charging and discharging cycles are also performed after a fixed interval of randomized usage to provide reference benchmarks for battery state of health.\n\nIn this dataset, four 18650 Li-ion batteries (Identified as RW9, RW10, RW11 and RW12) were continuously operated using a sequence of charging and discharging currents between -4.5A and 4.5A. This type of charging and discharging operation is referred to here as random walk (RW) operation. Each of the loading periods lasted 5 minutes, and after 1500 periods (about 5 days) a series of reference charging and discharging cycles were performed in order to provide reference benchmarks for battery state health.", "distribution": [{"@type": "dcat:Distribution", "downloadURL": "https://data.nasa.gov/docs/legacy/ames/1.Battery_Uniform_Distribution_Charge_Discharge_DataSet_2Post.zip", "format": "ZIP", "mediaType": "application/zip", "title": "Battery_Uniform_Distribution_Charge_Discharge_DataSet_2Post.zip"}], "identifier": "https://data.nasa.gov/api/views/ugxu-9kjx", "issued": "2022-10-20", "keyword": ["batteries", "degradation", "phm", "prognostics"], "landingPage": "https://data.nasa.gov/dataset/randomized-battery-usage-1-random-walk", "license": "https://www.usa.gov/government-works", "modified": "2025-12-09", "programCode": ["026:021"], "publisher": {"@type": "org:Organization", "name": "PCoE"}, "theme": ["Raw Data"], "title": "Randomized Battery Usage 1: Random Walk"}
