Abstract
A battery remaining power predicting device predicts a remaining power of a battery by a first computing flow for regressively calculating a battery open circuit voltage and the battery remaining power, based on a battery voltage and a battery temperature both measured, and a current value and a battery internal resistance calculated from a change in the battery remaining power. Further, the battery remaining power predicting device predicts the remaining power of the battery by a second computing flow for calculating a battery capacity and a battery internal resistance, based on a battery remaining power before the start of a constant current discharge, a battery voltage immediately before the stop of the constant current discharge, and a settled battery voltage after the stop of the constant current discharge, after the constant current discharge is performed for a predetermined period as a battery load.
