This application relates to the field of
electrochemical energy storage battery cluster technology, specifically to a method and apparatus for estimating the
state of charge of individual battery cells, an
energy storage battery cluster
system, a computer-readable storage medium, and a
computer program product. The method includes: acquiring global features and multiple individual
battery cell voltages; linearly projecting the global features and multiple individual
cell voltages onto a pre-defined dimension representation space to obtain global feature projections corresponding to the global features and individual
cell voltage projections corresponding to the multiple individual
cell voltages; determining the input representation based on the individual
cell voltage projections, global feature projections, and bidirectional position encoding; performing temporal self-attention
processing and individual cell distribution self-attention
processing on the input representation to obtain individual cell relationship representations; and determining the individual
cell state of charge regression value, individual cell health state regression value, individual cell equalizable charge regression value, and individual cell anomaly
binary classification probability based on the individual cell relationship representation and a multi-task collaborative prediction head. This method effectively solves the problem of redundant consumption of computational and storage resources.
