Abstract: A battery diagnostic device includes a first discharge process unit that performs a first diagnostic discharge, a first determination unit that determines whether a deterioration diagnosis of the battery is possible based on a physical quantity indicating the state of the battery during the first diagnostic discharge acquired by a first acquisition unit, a second discharge process unit that performs a second diagnostic discharge when it is determined that the deterioration diagnosis of the battery is impossible, and a diagnosis unit that performs the deterioration diagnosis of the battery based on the physical quantity acquired by the first acquisition unit when it is determined that the deterioration diagnosis of the battery is possible, and performs the deterioration diagnosis of the battery based on a physical quantity indicating the state of the battery during the second diagnostic discharge when it is determined that the deterioration diagnosis of the battery is impossible.

Abstract: An in-vehicle system for diagnosing a battery installed in a vehicle includes a processor. The processor is configured to control the battery to implement sensing discharge, which is discharge processing for sensing deterioration of the battery. The processor is configured to determine whether a result of the sensing discharge satisfies a predetermined condition. The processor performs deterioration determination of the battery when the result of the sensing discharge satisfies the predetermined condition. On the other hand, the processor controls the battery to implement the sensing discharge again when the result of the sensing discharge does not satisfy the predetermined condition.

Abstract: The present invention provides a starch with high dietary fiber content that does not deteriorate texture or flavor when added to a food. Provided is a phosphoric acid crosslinked starch obtained by subjecting a starting starch material to a phosphoric acid crosslinking treatment, wherein: when suspended in water to give a concentration of 7% by weight on the anhydrous basis, the starting starch material shows a gelatinization starting temperature of 80° C. or lower; in the phosphoric acid crosslinked starch, 70% by volume or more of particles have a particle diameter of 18-35 ?m; and the content of dietary fiber in the phosphoric acid crosslinked starch is 50% by weight or greater. The phosphoric acid crosslinked starch according to the present invention is useful in manufacturing compositions for dietary fiber enrichment, foods for restricting carbohydrate intake or low calorie foods.
