Battery aging tests are essential for evaluating performance and lifespan of batteries over time. The aging process can be affected by various factors, including
Lifetime. The standard method used by industry has two fundamental test regimes as inputs: calendar ageing – where the cells are held at different fixed temperatures and SoC.; cycle ageing – where the cells are cycled through a complete charge discharge at different fixed temperatures.; At regular intervals the capacity of the cells are measured.
This table covers ageing tests for Li-ion batteries. It is made in the European projects eCaiman, Spicy and Naiades. 7.6.1 Storage tests - Charge retention test. 7.5 SOC loss at storage / 7.4 No-load SOC loss. 7.6 SOC loss at storage / 7.5 No load SOC loss.
The aforementioned reactions have different impacts on battery capacity loss in a specific aging process [72, 73], which can be used to diagnose the aging of batteries. At present, the diagnosis methods can be classified into three categories: disassembly-based post-mortem analysis, curve-based analysis, and model-based analysis.
The existing quantitative diagnosis consists of two steps. The first step is to classify the battery aging reactions. LLI and LAM are the most common aging modes. On this basis, Birkl et al. believe that LAM includes two modes: LAM NE and LAM PE .
It is necessary to study battery aging mechanisms for the establishment of a connection between the degradation of battery external characteristics (i.e. terminal voltage or discharging power) and internal side reactions, in order to provide reliable solutions to predict remaining useful life (RUL), estimate SOH and guarantees safe EV operations.
Since the aging reactions include cathode degradation, anode degradation, and SEI formation, their respective contribution rates to battery aging can be calculated as the equivalent capacity loss which is considered as the amount of active lithium-ion loss.
For curve-based analysis, the comment flow can be divided into three steps: (1) obtain clear IC/DV curves from battery charging curves; (2) extract feature points (FOIs), including position or height of peaks, area under IC peaks, etc.; (3) diagnose battery aging in current BMSs using the look-up table method.
