Field: Semiconductors (Electrical engineering)
Classification: CPC H  B  G  Y | IPC B  G  H

Claim 7:
8. A power storage system comprising:
a storage battery, a neural network, a first circuit, a second circuit, and a sensor element,
wherein the neural network comprises an input layer, an output layer, and one or a plurality of middle layers provided between the input layer and the output layer,
wherein a measurement value of one or both of strain and temperature is supplied to the first circuit as a first signal,
wherein the first signal is an analog signal,
wherein the first circuit is configured to convert the first signal into a second signal that is a digital signal,
wherein the first circuit is configured to modulate the second signal and supply the modulated signal to the second circuit through wireless communication,
wherein the second circuit is configured to demodulate the signal supplied from the first circuit through wireless communication and supply the signal to the input layer,
wherein the sensor element comprises a region in contact with a surface of the storage battery,
wherein a corrected value of the signal supplied to the input layer is output from the output layer, and
wherein the sensor element starts sensing in response to an analysis result of a change in a current value of the storage battery over time by the neural network.
