Abstract: A method of manufacturing a multilayer metal plate by electroplating includes a first forming operation of forming one of a first metal layer and a second metal layer on a substrate by electroplating, wherein the second metal layer is less recrystallized than the first metal layer, the second metal layer is comprised of nanometer-size grains, and the second metal layer has a higher level of tensile strength than the first metal layer; and a second forming operation of forming, by electroplating, a third metal layer not formed in the first forming operation on a surface of one of the first metal layer and the second metal layer formed in the first forming operation.

Abstract: Provided is an output control method of a parallel battery energy storage device including an inverter. More particularly, the present disclosure relates to an output control method, wherein when an external battery is connected in parallel to an inverter equipped with an internal battery and is used, output power is limited depending on a capacity of the external battery, thereby ensuring user safety.
