These files contain experimental results collected in 2018 during testing of six second-life electric vehicle batteries under a 24-hour frequency regulation (FR) duty-cycle prescribed by Sandia National Laboratories (SNL). The maximum FR power in the duty-cycle is four times the 4-hour constant-power discharge rate of the battery in question. 'MeasureLogger' files contain 1-second measurement logs collected during each test. 'SummaryLogger' files contain summaries of the measurements collected during each programmed step in the test protocol. The 'Legend' file elaborates on the column headers used in the MeasureLogger and SummaryLogger files, as well as the programmed steps in the test protocol.
