Abstract: Provided are a secondary battery degradation determination method and a secondary battery degradation determination device which can detect degradation of a secondary battery in advance even before an engine starts. When it is determined in Step S1 that a vehicle is in a stop state, a stable-state open-circuit voltage OCV is measured in Step S2 and internal resistance R1 is calculated in Steps S3 and S4. On the other hand, when it is determined in Step S1 that a starter 21 is operated, a maximum discharge current value Inew is measured in Step S5 and a maximum discharge current value Is is updated in Steps S6 and S7. In Step S14, a minimum voltage Vs is calculated. In Step S15, the stable-state open-circuit voltage OCV and the minimum voltage Vs are compared with predetermined threshold values to perform the degradation determination of a secondary battery 10.

Abstract: A tapered waveguide is optically connected to an end surface of an optical fiber bundle part, and has a tapered part that changes in outside diameter in a tapered shape. The fiber bundle part is optically connected to the end surface of the large-diameter side of the waveguide. The entire waveguide has a substantially uniform index of refraction. A delivery fiber is optically connected to the end surface on the small-diameter side of the waveguide. As with the fiber bundle part the delivery fiber passes through a hole in a capillary and is affixed. The capillaries are each affixed to a retaining member such that the fiber bundle part, the waveguide, and the delivery fiber are disposed on the same axis and optically connected. The waveguide is retained in a state floating from the retaining member, and the outside surface of the waveguide is not in contact with the retaining member.

Abstract: A secondary battery state detection device for detecting the state of a secondary battery includes at least one processor and at least one memory that is communicably connected to the at least one processor. The at least one processor reads a set of instructions stored in the at least one memory, and executes detection processing in which a charging voltage is detected, the charging voltage being generated when an alternator that generates an adjustable voltage charges the secondary battery; computation processing in which a charging resistance is computed as an internal resistance of the secondary battery when the alternator charges the secondary battery; and estimation processing in which a state of charge of the secondary battery is estimated on the basis of the charging voltage detected by the detection processing and on the charging resistance computed by the computation processing.
