Beschreibung
Zusammenfassung:	An estimation device for estimating a residual electricity amount of an energy storage cell or an assembled battery is configured to perform: first processing of estimating the residual electricity amount based on an integrated value of a current of the energy storage cell or the assembled battery; second processing of estimating an accumulated error of the residual electricity amount based on an integrated value of a measurement error of the current; third processing of estimating the residual electricity amount by a method that differs from the first processing; fourth processing of calculating a residual electricity amount difference that is a difference between the residual electricity amount estimated in the first processing and the residual electricity amount estimated in the third processing; and fifth processing of calculating a correction value of the measurement error based on the accumulated error and the residual electricity difference.
