Abstract
A secondary-battery maximum-capacity measuring apparatus, includes: a current dependency processing unit configured to convert an inter-terminal voltage and an open cell voltage of a secondary battery into values without depending on a load current based on an amount of change in relative value of a voltage during a time period when a constant current is drawn from the secondary battery; and an error calculation unit configured to compute errors of the inter-terminal voltage and the open cell voltage of the secondary battery, the inter-terminal voltage and the open cell voltage being converted by the current dependency processing unit.
