Li-ion Battery Dataset (NASA)

Source: R/data_NASA.R

These data are from four batteries, which were instrumented to capture the value of variables such as current, temperature and voltage from sensors. The batteries were subjected to charging and discharging processes in a controlled environment with a constant ambient temperature. The batteries are named like this:

  • Battery 5

  • Battery 6

  • Battery 7

  • Battery 18
