However, the phenomenon of capacity recovery (CR) may impede the progress of improving battery capacity prediction performance.
To analyze the capacity degradation process, batteries need to be cycled in various working conditions, in which a CC discharging process or a CC charging process is conducted to obtain battery discharging or charging capacity in each cycle. Fig. 2 (a) shows a typical cycling condition for battery cells tested in laboratory.
The phenomenon of capacity recovery (CR) (also known as capacity regeneration) refers to that of battery capacity recovery after a suspension of charge/discharge cycles. In early studies [ 14, 15 ], this phenomenon was regarded as unpredictable perturbation information, and the lithium battery RUL was predicted by separating the effects of CR.
In this case, the capacity recovery phenomenon is a major challenge for the prediction task. The phenomenon of capacity recovery (CR) (also known as capacity regeneration) refers to that of battery capacity recovery after a suspension of charge/discharge cycles.
