Abstract: A method of estimating a state of health of a battery is performed by at least one computing device, and includes preparing a pre-trained artificial neural network, generating input data by measuring at least one parameter of the battery, inputting the input data into the pre-trained artificial neural network to obtain a health state estimation value of the battery and an attention map, calculating an attention score based on the attention map, and determining whether to trust the health state estimation value based on the attention score.
