Abstract
A device capable to accurately controll a battery,, which is charged by an electric power supplied through a power supplying line,for charging, is provided. The control device for a battery,includes: voltage measuring means Vm for measuring a terminal voltage of the battery,current measuring means Im for measuring a charging current flowing through the power supplying line,for charging; charging characteristic computing means,A for computing an approximate correlated linear characteristic between the terminal voltage and the charging current on the basis of periodic changes in the terminal voltage measured by the voltage measuring means Vm and in the charging current measured by the current measuring means Im during a charging operation of the battery,and full charging capacity computing means,B for computing a full charging capacity of the battery,on the basis of the approximate correlated linear characteristic computed by the charging characteristic computing means,A and a predetermined reference value of the charging current.
