Abstract
A remaining charge detection device for a power storage unit including a current detection unit which detects the current value of a charging current and a discharging current of a power storage unit; a voltage detection unit which detects the voltage value of a terminal voltage of the power storage unit; and a current accumulation remaining charge calculation means which accumulates the current value detected by the current detection unit to obtain an accumulated charging current and discharging current and calculates a remaining charge of the power storage unit. The remaining charge detection device further includes a no-load state detection unit which detects a no-load state of the power storage unit, and a remaining charge for calibration calculation unit which calculates a remaining charge for calibration for the remaining charge of the power storage unit.
