PROBLEM TO BE SOLVED: To provide a method of detecting the remaining capacity of a battery more correctly. SOLUTION: The remaining capacity of the battery detection method is composed of: the operation for measuring the current and the voltage of the battery; the operation for the remaining capacity of the battery as the first remaining capacity based on the integration of the measured battery current; while the operation for the remaining capacity of the battery as the second remaining capacity based on the battery voltage; the operation for the synthetic weighted mean of the first remaining capacity and the second weighted mean as the remaining capacity of the battery, wherein the region the amount of the remaining capacity is large or small the weight of the second remaining capacity is made large, and other than that region, the weight of the first remaining capacity is made large.
