The current research on power battery life is mainly based on single batteries. As known, the power batteries employed in EVs are composed of several single batteries. When a cell is utilized in groups, the performance of the battery will change from more consistent to more dispersed with the deepening of the degree of application.
Consumers’ real-world stop-and-go driving of electric vehicles benefits batteries more than the steady use simulated in almost all laboratory tests of new battery designs, Stanford-SLAC study finds. The way people actually drive and charge their electric vehicles may make batteries last longer than researchers have estimated. | Cube3D
Lithium-ion batteries degrade in complex ways. This study shows that cycling under realistic electric vehicle driving profiles enhances battery lifetime by up to 38% compared with constant current cycling, underscoring the need for realistic loads to capture ageing mechanisms.
Almost always, battery scientists and engineers have tested the cycle lives of new battery designs in laboratories using a constant rate of discharge followed by recharging. They repeat this cycle rapidly many times to learn quickly if a new design is good or not for life expectancy, among other qualities.
In addition, unlike most models that require multiple battery data of the same type for training, the proposed model only requires the use of fragmented data of the target battery with length around 30-50 cycles for capacity prediction and determines battery life based on battery failure thresholds.
Because of the problem of battery consistency, the study of battery life is emphasized. Due to the inconsistency of battery packs, digital generation and artificial intelligence technology should be further applied in the field of battery pack life prediction.
