An auxiliary power supply system includes a plurality of electrical storage devices that supply power to an electrical device. Each of the storage devices has the communication capability with the electrical device. Each of the storage devices provisionally selects one of a plurality of first communication addresses as a provisional communication address of its own. The plurality of first communication addresses have been set for the plurality of electrical storage devices by the electrical device. Each of the storage devices returns a response signal in reply to a transmission signal, to which the provisional communication address of its own is added. Each of the storage devices changes, when finding that any communication error has occurred while returning the response signal, the provisional communication address of its own into one of one or more unused communication addresses belonging to the plurality of first communication addresses that have been set.

Auxiliary power supply system, module, auxiliary power supply control method, and program

A backup power supply system of the present invention includes a first auxiliary power supply and a second auxiliary power supply capable of supplying electric power to a first load when failure of a main power supply occurs. In the backup power supply system, a second duration is shorter than a first duration. The first duration is the duration until the first auxiliary power supply becomes capable of supplying electric power to the first load. The second duration is the duration until the second auxiliary power supply becomes capable of supplying electric power to the first load.

Backup power supply system, power supply backup method, and program

A backup power-supply system according to the present invention includes a detector, a power storage unit, and a controller. The detector is configured to detect an abnormality of a power supply that supplies electric power to loads. The power storage unit is configured to supply electric power to the loads when the detector detects the abnormality of the power supply. The controller is configured to monitor a remaining electric energy remaining in the power storage unit, and impose, when the remaining electric energy of the power storage unit is smaller than a threshold electric energy, a limitation on the loads to which the power storage unit supplies the electric power.

Backup power supply system and vehicle

A vehicle electricity storage device includes a capacitor unit for supplying stored electric power to an electronically controlled system, and a microcomputer including a memory. The memory stores a plurality of thresholds (internal resistance limit values) different from each other. Each of the plurality of thresholds is to be compared with an electrical characteristic value (internal resistance value) related to the capacitor unit for determining a deterioration state of the capacitor unit. The each of the plurality of thresholds is stored in association with an identification ID for identifying the electronically controlled system. The microcomputer acquires the identification ID from the electronically controlled system. And the microcomputer selects, from the plurality of thresholds, a threshold associated with the identification ID acquired. Then the microcomputer determines the deterioration state of the capacitor unit by using the electrical characteristic value and the threshold selected.

Vehicle electricity storage device

A hearing aid () comprises a body case () that is worn behind an ear (), a sound conductor () that is linked at one end to the body case () and is linked at the other end to an earpiece (), and an engaging component () for holding the earpiece linked to the other end of the sound conductor in the external auditory canal () of the ear (). The engaging component () is made up of a first arc part () disposed on the earpiece () side, a second arc part () that is larger than the first arc part () and is disposed opposite the first arc part (), a first linking part () that links one end of the first arc part () and one end of the second arc part (), and a second linking part () that links the other end of the first arc part () and the other end of the second arc part (). The second linking part () has a shape such that its center part protrudes toward the first linking part (). This constitution allows the hearing aid () to be put on more easily.
