Abstract
A battery remaining capacity measuring apparatus comprises a temperature sensor 5 and a remaining capacity operation portion 19. A temperature sensor 5 detects a temperature of a battery 3. A remaining capacity operation portion 19, wherein when a detected temperature of a battery 3 from a temperature sensor 5 is not within the range of a predetermined temperature in the state of an open circuit, a load 1 and a battery 3 which are previously obtained according to a detected temperature correct a line pattern in the state of an open circuit and when a load is connected to a battery, a remaining capacity can be obtained on the corrected line. Accordingly, it is possible to obtain a remaining capacity according to this temperature, even if a temperature of a battery 3 is not within the range of a predetermined temperature.
