Abstract: An electrode manufacturing device that applies pressure to an electrode containing a coating part and a non-coating part is provided. The electrode manufacturing device includes: a first pressure roll that applies pressure to the non-coating part; a second pressure roll that applies pressure to the coating part; and a connection part that penetrates through the center of the first pressure roll and the center of the second pressure roll, respectively, wherein a difference between a radius of the first pressure roll and a radius of the second pressure roll is equal to or smaller than a step difference between the coating part and the non-coating part.

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.
