In this review, three CCA methods for lithium-ion batteries are analyzed and described from the aspects of mechanism mapping analysis and data-driven application. The diagnosis process of battery aging mechanism is stated and the detailed steps of constructing data-driven models are introduced.
Degradation of lithium-ion batteries is also influenced by external factors such as temperature, rate of charge/discharge, SOC, and cycle numbers [ 61, 62 ]. The battery characteristic curve reflects the phase transition process during the cycle as well as the macroscopic battery capacity and resistance.
The cathode electrode determines the potential of the lithium-ion battery. Damage to the cathode material leads to a slightly lower battery potential upon full recharge after impact and causes partial capacity loss of the lithium-ion battery. 3.3. Discussion on the redundancy design of a Li-ion battery under high-dynamic impacts
Power battery technology is essential to ensuring the overall performance and safety of electric vehicles. Non-invasive characteristic curve analysis (CCA) for lithium-ion batteries is of particular importance.
The irreversible capacity loss of lithium-ion batteries after high-dynamic impact is a novel discovery, and the permanent loss of capacity after multiple impacts is particularly severe. This can explain the failure of power sources in multilayer penetrating ammunition during operation, forcing more redundancy in the energy design of the system.
On behalf of all the authors, the corresponding author states that there is no conflict of interest. Cao, R., Cheng, H., Jia, X. et al. Non-invasive Characteristic Curve Analysis of Lithium-ion Batteries Enabling Degradation Analysis and Data-Driven Model Construction: A Review. Automot.
The major conclusions can be summarized as follows: 1. The capacity of lithium-ion batteries is permanently lost under a high-dynamic strong mechanical impact, and the capacity loss increases with increasing impact strength. Notably, the irreversible capacity loss caused by multiple high-dynamic mechanical impacts has a sharp cumulative effect.
