Claim 0:
1. A power storage system comprising:
a storage battery, a neural network, 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 the neural network is configured to perform an analog operation without analog/digital conversion,
wherein a value corresponding to a first signal output from the sensor element is supplied to the input layer,
wherein the first signal is an analog signal,
wherein the storage battery comprises an exterior body covered with an insulating surface, and
wherein the sensor element comprises a strain sensor and is configured to sense expansion of the exterior body due to gas generation in the storage battery.
