An abnormality detection device of an embodiment includes an encoder, a first identifier, a decoder, and a second identifier. The encoder is configured to compress input data using a compression parameter to generate a compressed data. The first identifier is configured to determine whether a distribution of the compressed data input by the encoder is a distribution of the compressed data or a prior distribution prepared in advance, and inputs a first identification result to the encoder. The decoder is configured to decode the compressed data using a compressing parameter to generate reconstructed data. The second identifier is configured to determine whether the reconstructed data input by the decoder is the reconstruction data or the input data and outputs a second identification result to the encoder and the decoder.

A power demand estimating apparatus includes a demand data memory, a demand estimator, and a display. The demand data memory stores plural power demand patterns and power demand amount data. The demand estimator selects, from the demand data memory, the demand pattern matching the environmental condition on an estimation day, obtains the maximum value of an power demand amount and the minimum value thereof at an expected temperature on the estimation day, calculates, using those pieces of information, the power demand amount per a unit time on the estimation day, and creates a demand estimating model. The display displays, together with the power demand pattern selected by the demand estimator, the demand estimating model.

An apparatus is disclosed that includes a resistance measuring unit operable to determine a solution resistance Rsol and a charge transfer resistance Rct of a battery; and at least one computer-readable non-transitory storage medium comprising code, that, when executed by at least one processor, is operable to provide an estimate of the present value of the battery by: comparing Rsol and Rct to historical deterioration transition information; estimating the number of remaining charge cycles before a discharge capacity lower limit is reached by the battery using the comparison; and estimating the number of remaining charge cycles before a discharge time lower limit is reached by the battery using the comparison. The estimate of the present value of the battery includes the smaller of the number of remaining charge cycles before a discharge capacity lower limit is reached or the number of remaining charge cycles before a discharge time lower limit is reached.

Battery diagnosis device and method

An assembled battery system is disclosed that includes a plurality of serially-connected battery cells; voltage detecting lines connectable at one ends to electrodes of the battery cells of the assembled battery; electric resistors serially-connected at one ends to the other ends of the voltage detecting lines; capacitors connected to the other ends of the electric resistors, each of the capacitors being configured to electrically interconnect one of the voltage detecting lines and the other voltage detecting line; voltage measuring circuits connected respectively to each of the voltage detecting lines; electrically openable short-circuiting switches arranged between the capacitors and the voltage measuring circuits and parallel-connected to the capacitors; and a monitoring circuit that detects a difference between a first measurement result and a second measurement result with respect to each of the short-circuiting switches and a failure of the voltage detecting lines, the short-circuiting switches or the voltage measuring circuits.

Assembled battery system and failure detection method of assembled battery system

An image recording and playing system includes: an image pickup unit that takes an image; a processing unit that performs an image processing of the image data obtained by the image pickup unit; a display unit that displays an image based on an image processing result; and a memory that stores an image data based on the image processing result, wherein the processing unit includes: a dissimilar image extracting element that determines whether the each extracting objection image data preliminarily read is a dissimilar image data to the image data obtained by the image pickup unit and extracts image data determined as the dissimilar image data; a data storing element that stores the dissimilar image data; and a thumbnail image creating unit that extracts image data similar to a typical-pattern image data extracted from among the dissimilar image data, and creates thumbnail image data.
