摘要： PROBLEM TO BE SOLVED: To estimate the remaining capacity of a battery without affecting the life of the battery. SOLUTION: A remaining capacity estimating section 6 stores the average current consumption per unit time consumed by various sections operated by the battery 5 in a stationary state and stores the current consumption for one occurrence of an abnormality. The current consumption in the stationary state is calculated by measuring the operating time, counting the number of occurrences of the abnormality, and multiplying the average current consumption and the measured operating time together. The current consumption in an abnormal state is calculated by multiplying the current consumption for one occurrence of the abnormality and the measured number of occurrences of the abnormality together. The calculated current consumption is subtracted from the initial current capacity of the battery 5.
