Complex testing procedure for 18650 batteries
The dataset consists of results of 10 different tests conducted on 8 different types of battery cells. All batteries are designed in 18650, but they differ in manufacturer and composition. The measurements can be divided into three groups: constant load tests, WLTP tests at different temperatures and transient tests. Constant load tests are performed at 0.1C and 1C as a function of battery capacity, both during charging and discharging. During transient tests, a 360s load/charge is followed by a 60s relaxation. A WLTP current profile is used for dynamic loads and measurements are performed at 4 different temperatures of 25°C, 0°C, -15°C, 60°C.
By publishing the measurement results, the aim is to provide data on the behavior of different brands of cells under different conditions. It is worth to note that the provided measurement set is not suitable for qualifying individual battery types.
