Estimating the term…
In a secondary battery charging method, constant current charging is performed until a first predetermined voltage V0 is attained, constant voltage charging is then performed at the first predetermined voltage V0, the first constant voltage charging is completed when a charge current becomes (In−ΔIn) from In, and then n is incremented by one; and constant voltage charging is performed at a voltage Vn=Vn-1+ΔVn, a step of completing the n-th constant voltage charging when the charge current becomes (In−ΔIn) from In is repeated by incrementing n by one, and the N-th constant voltage charging in which a value of the voltage Vn reaches a second predetermined voltage VN (>V0) is completed to terminate the constant voltage charging.
A secondary battery charging method in which constant current charging is performed until a first predetermined voltage V0 is attained, constant voltage charging is then performed at the first predetermined voltage V0, the first constant voltage charging is completed when a charge current becomes (In−ΔIn) from In, and then n is incremented by one, and
A secondary battery charging method in which when a value of a constant current in constant current charging is regarded as I0, constant current charging is performed by combining a constant current value k1·I0 (provided that, 0.4<k1<1) and the constant current value I0, and then constant voltage charging is performed.
