Researchers have developed new methods for estimating the State of Health (SOH) of lithium-ion batteries, particularly when labeled data is scarce. One approach utilizes degradation-aligned self-supervised learning with a CNN-GRU model, achieving low error rates even with only 1% labeled data. Another method employs physics-informed neural networks to estimate SOH and predict degradation in real-time using partial battery discharge data, offering a more robust solution for heterogeneous operating conditions.
