摘要

A battery remaining power calculating method, battery remaining power calculating device, battery and remaining power calculating program for predicting the remaining power of a secondary battery with high accuracy by using a relatively simple circuit structure. The output voltage value of a second battery is measured. The use mode is divided into a high-consumption mode in which the output current is a predetermined threshold or more and a low-consumption mode in which the output current is below the predetermined threshold. In the low-consumption mode, the remaining power is calculated from the output voltage value and a predetermined reference voltage curve, which is a discharge characteristic of the secondary battery. In the high- consumption mode the remaining power is calculated assuming that the variation of the remaining power of when the low-consumption mode is changed to the high-consumption mode is almost zero. Alternatively, in the high-consumption mode, the remaining power may be calculated from a reference remaining power before the use mode is changed, the start voltage which is the output voltage when the high-consumption mode starts, a predetermined cutoff voltage of the secondary battery, and the output voltage value.
