Abstract

See full text

To provide a battery pack capable of performing a highly accurate prediction of a remaining power of a battery while being low in cost. A battery remaining power predicting device includes a voltage detection portion which measures a voltage and a temperature of a battery, a computing portion which predicts and calculates a remaining power of the battery, and a controller which controls the computing portion, and has a battery remaining power predicting flow for regressively calculating the battery remaining power, and a secular change estimating flow for estimating a secular change in battery characteristics, using a case where a battery current is in a constant current state.
