Abstract

Provided is a battery control device that can accurately detect a state of charge even if characteristics relating to the state of charge change as a result of battery degradation. This battery control device is provided with map data describing the correspondence relationship between an open-circuit voltage and a state of charge of the battery and outputs different state-of-charge values for the same open-circuit voltage according to the amount of elapsed time.
