AI Customer ServiceThe direct evaluation method for battery cycle life is measuring the cell capacity attenuation value and testing the internal resistance increase value [ 21, 22 ]. Two important works for accelerated aging tests are establishing an accurate capacity attenuation model and determining the reasonable upper limit of the accelerated stress.
The test time for battery cycle life under divided SOC intervals can be significantly shortened. However, from the previous analysis, the capacity attenuation model trained by aging data under divided SOC intervals cannot be perfectly applied to the aging condition under the entire SOC interval.
Section 4 proposes a fast evaluation method based on the integrated algorithm and the experimental results. In Sect. 5, some conclusions and directions for future work are presented. The cycle life of a lithium-ion battery is defined as the maximum cycle number when the end of life is reached (generally 80% of the rated capacity).
They also show that the cycle life estimation error can be ranged within 3%. In addition, the cycle time of the aging test can be reduced to about one fifth of that with the traditional method. The cycle life of a lithium-ion battery is important for the safety and reliability of power systems.
A joint estimation method is established for battery capacity, loss of lithium inventory (LLI), and loss of active material (LAM). This article aims to fill in aforementioned knowledge gaps, and develop an efficient cycle life evaluation method for ternary lithium-ion batteries.
Therefore, the innovation of this paper is a fast cycle life evaluation method for ternary lithium-ion batteries combing the accelerated aging test and the regression model. The capacity attenuation estimation error can be further reduced. A flow chart of the proposed fast evaluation method is shown in Fig. 10.
