Abstract: A battery capacity calculating method can very accurately calculate a residual capacity of a secondary battery especially in the last stage of discharging independently of environmental conditions such as a temperature or a deteriorated state. A battery capacity calculating apparatus (10) is equipped with a voltage measuring circuit (11) which measures the terminal voltage (Vmea) of a battery (1) at the time of discharging, a current measuring circuit (12) which measures the current value (I) of the battery (1) at the time of discharging, and a control circuit (13) which calculates a residual capacity and/or residual power. The operation unit (15) in the control circuit(13) calculates a discharged capacity (Qmea) and an apparent discharged capacity (Qocv) based on a terminal voltage (Vmea) and a current value (I) measured by the voltage measuring circuit (11) and the current measuring circuit (12), respectively, estimates a discharge curve (Cpre) in the future including the last stage of discharging based on a capacity shift ( DELTA Q) being the difference between the discharged capacity (Qmea) and the apparent discharged capacity (Qocv) during discharging, and calculates the residual capacity and/or the residual power of the battery (1) based on the estimated discharge curve (Cpre).

Abstract: A battery pack capable of preventing manufacture of an altered battery pack by a simple construction and a simple structure is provided. The battery pack has a plurality of secondary batteries and an inspection circuit. Each of the secondary batteries is previously given an identification mark. When the plurality of secondary batteries are classified into a first secondary battery group configured of secondary batteries selected from the plurality of secondary batteries and a second secondary battery group configured of remaining secondary batteries not belonging to the first secondary battery group, the inspection circuit creates a first data string of the secondary batteries configuring the second secondary battery group, based on a predetermined arithmetic rule, from identification marks of the secondary batteries configuring the first secondary battery group, obtains a second data string by examining identification marks of the secondary batteries configuring the second secondary battery group, subsequently compares the first data string with the second data string, and stops a function of the battery pack when the first data string and the second data string do not match.
