Abstract: A data acquisition unit acquires usage data of a secondary battery and battery information for specifying the type of the secondary battery. A degradation characteristic search unit searches a degradation characteristic database on the basis of the battery information and specifies a degradation characteristic information that includes a storage degradation characteristic, a charging degradation characteristic, and a discharging degradation characteristic of the secondary battery. A degradation state analysis unit estimates a storage degradation amount, a charging degradation amount, and a discharging degradation amount of the secondary battery on the basis of the usage data of the secondary battery and the specified degradation characteristic information.

Abstract: In a battery abnormality detection system, a data acquirer acquires a current flowing through a battery and a temperature of the battery. A determiner determines presence or absence of abnormal heat generation of the battery based on a relation between an amount of the current flowing through the battery in a certain period and a temperature rise of the battery in the certain period. The determiner determines the presence or absence of the abnormal heat generation of the battery based on the current and the temperature of the battery in a charging period in which the temperature of the battery exceeds a set temperature.

Abstract: A lighting device includes a light emitting element; a first lens that captures and emits light generated by the light emitting element; and a second lens that captures light emitted from the first lens and emits the light in a predetermined direction. The first lens includes a first-lens-entrance through which the light generated by the light emitting element enters, a first lens exit that emits the light entered from the first-lens-entrance and transmitted through an inside of the first lens, and a plurality of first-lens-side-portion-wall-surfaces that are provided between the first-lens-entrance and the first lens exit. The plurality of first-lens-side-portion-wall-surfaces include a reflection-side-surface-portion that reflects the light entered the inside of the first lens from the first-lens-entrance, and a side surface portion that is configured to allow light having a luminous intensity smaller than a luminous intensity of light entering the reflection-side-surface-portion to enter.

Abstract: A data acquisition unit acquires temperature data for a plurality of battery packs mounted on different equipment (e.g., electric-powered vehicle) in a predetermined period. A statistical calculation unit calculates, for each battery pack, a statistical value based on a temperature change rate in a plurality of charging periods included in the predetermined period. A determination unit determines a temperature adjustment function of the equipment for which a deviation of the statistical value based on the temperature change rate is equal to or greater than a threshold value to be abnormal.
