Abstract
A battery-state monitoring apparatus includes: a secondary batterysupplying an electric power to portable equipment; and an operation processing partthat can detect a battery state of the secondary batteryin a detection mode to detect the battery state of the secondary battery, the operation processing part using the secondary batteryas a power source, wherein the battery-state monitoring apparatus includes a start-up current detecting partdetecting a start-up of the portable equipment, and wherein the operation processing partwaits for a detection of the battery state in a standby mode in which power consumption is smaller than the detection mode until the start-up is detected by the start-up current detecting part, and, on the other hand, the operation processing partdetects, by intermittently performing a temporary return from the standby mode to the detection mode, the battery state of the secondary battery in a return period during which the return is made.
