Online state-of-charge (SOC) estimation for lithium-ion batteries is one of the most important tasks battery management system in ensuring its operation safety and reliability. Due to advantages learning long-term dependencies between sequential data, recurrent neural networks (RNNs) have been developed shown their superiority over SOC estimation. However, only time-series measurements (e.g., voltage current) are taken as inputs these RNNs. Considering that mapping relationship evolves along...
