Randomized Battery Usage 3: Room Temperature Variable Recharge Random Walk

Reference charging and discharging cycles are also performed after a fixed interval of randomized usage to provide reference benchmarks for battery state of health. In this dataset, four 18650 Li-ion batteries (Identified as RW1, RW2, RW7 and RW8) were continuously operated by repeatedly discharging them to 3.2V using a randomized sequence of discharging currents between 0.5A and 4A.

This type of discharging profile is referred to here as random walk (RW) discharging. After each discharging cycle the batteries were charged for a randomly selected duration between 0.5 hours and 3 hours. After every fifty RW cycles a series of reference charging and discharging cycles were performed in order to provide reference benchmarks for battery state health.
