For real-world scenarios, the accurate and reliable SOC and capacity estimations for large-sized series-connected battery packs are challenging due to the unpredictable driving profiles, low-quality data acquisition, and the limited computation and storage capabilities of BMSs.
To address the above research gaps and accelerate the second-use progress of EV batteries, a fast and accurate screening performed by pack-level testing is proposed for the evaluation and classification of module-level aging. The main contributions of this work are as follows:
The proposed approach is validated thoroughly with both laboratory and field data. Accurate state-of-charge (SOC) and capacity estimations are of great importance for the performance management, predictive maintenance, and safe operation of lithium-ion battery packs in electric vehicles (EVs).
Despite the satisfactory estimation accuracy and detailed perception of cell-to-cell inconsistencies, the MDM/MCM-based approaches are impractical for large-sized battery packs consisting of hundreds of cells due to their heavy dependence on computation and storage capabilities.
The Predictor includes four main components: In a, the past X of the model input matrix involves a 500-s time window time series including total voltage (TV), charging current (I), charging capacity (Q) of the battery system and the corresponding future Y is the 500-s cell voltage response. Both time windows of X and Y samples every 1-s a stride.
First, the adaptability of the proposed approach on battery packs with varying degrees of degradation and inconsistency. Second, research extending to other battery chemistries, such as nickel-manganese-cobalt and lithium-titanate-oxide, is needed in the future.
