Abstract
In a secondary battery charging method, constant current charging is performed until a first predetermined voltage Vis attained, constant voltage charging is then performed at the first predetermined voltage V, the first constant voltage charging is completed when a charge current becomes (I−ΔI) from I, and then n is incremented by one; and constant voltage charging is performed at a voltage V=V+ΔV, a step of completing the n-th constant voltage charging when the charge current becomes (I−ΔI) from Iis repeated by incrementing n by one, and the N-th constant voltage charging in which a value of the voltage Vreaches a second predetermined voltage V(>V) is completed to terminate the constant voltage charging.
