A method of charging a battery, wherein the battery comprises a plurality of battery cells, includes charging the battery with a first voltage for a first time period, which charging is first charging, charging the battery with a second voltage for a second time period, which charging is second charging, and charging the battery with a third voltage for a third time period, which charging is third charging, wherein lengths of the first to third time periods are determined in correspondence with a magnitude of charging current of the battery.

Battery charging method with mutiple constant voltages and battery charging apparatus employing the same

Embodiments of the present invention provide an accelerated lifetime estimation device for predicting the lifetime of a secondary battery, and a method thereof. The accelerated lifetime estimation device can accurately estimate a normal lifetime of the secondary battery while reducing an evaluation time period of the secondary battery.

Device for estimating a lifetime of a secondary battery and method thereof
