Abstract: An estimation apparatus that estimates a degradation amount of an energy storage device includes: a storage unit; and an arithmetic processing unit. The energy storage device has a characteristic of including a first degradation area in which a temporal transition of a degradation amount shows a first transition and a second degradation area in which the temporal transition of the degradation amount shows a second transition. The storage unit holds first arithmetic data for calculating the degradation amount in the first degradation area, and second arithmetic data for calculating the degradation amount in the second degradation area. The arithmetic processing unit executes determination processing of determining a degradation area of the energy storage device, and estimation processing of selecting arithmetic data corresponding to the degradation area from the storage unit to estimate the degradation amount of the energy storage device.

Abstract: Provided are a data processing apparatus, a data processing method and a computer program. The data processing apparatus processes measured data of a plurality of power storage devices, comprises: a storage unit that stores determination model using an autoencoder, which is trained to reproduce measured data when measured data is input, the input measured data being of each of the plurality of energy storage devices or of each group of energy storage devices, which is grouped from the plurality of the energy storage devices; and a processor. The processor determines the measured data of an odd energy storage device out of the measured data for each of the energy storage devices or for each group of energy storage devices based on an error between reproduced measured data, which is output when the measured data is input to the determination model, and the measured data.

Abstract: A lead-acid battery (100) is provided with a lid (14). An external flow passage (530) communicating with a communication chamber (520) through a vent hole (321) and communicating with a discharge port (405) of a lid (14) is formed inside the lid (14). A compartment fence (452, 454) continuously extending over the entire width of the external flow passage (530) is formed in the external flow passage (530). A residual volume is larger than the volume of the communication chamber (520), the residual volume being obtained by subtracting, from the total volume of a plurality of external spaces (460, 462, 464) divided by the compartment fence (452, 454), the volume of the discharge-side external space (464) closest to the discharge port among the plurality of external spaces.
