Abstract: A battery charging service system for an electrification vehicle and a method thereof are provided. The battery charging service system includes a mobile charger including at least one energy storage system (ESS), a working device that provides a battery charging service using the mobile charger, and a service device connected with the working device over a network. The service device collects a position and a remaining battery capacity of a user’s vehicle, classifies a target vehicle which needs battery charging in a service area based on the position and the remaining battery capacity of the user’s vehicle, and transmits a work instruction to the working device taking charge of the service area.

Abstract: Disclosed is a method for operating a fastening apparatus which includes a plurality of fastening devices, and support plates to which the plurality of fastening devices are connected by a variation mechanism to be movable. The method includes: moving the fastening devices along circumferential directions of the support plates or along a radial direction of the support plates depending on a shape and a structure of a workpiece, so that positions of the plurality of fastening devices vary.

Abstract: A fastening apparatus includes: a main structure, a movable structure mounted to be vertically movable with respect to the main structure, a support connected to the movable structure, a plurality of fastening devices mounted on the support, and a variation mechanism to vary fastening positions of the fastening devices. In particular, the variation mechanism changes the fastening positions on a 2-dimensional coordinate, and also individually moves the plurality of fastening devices along a radial coordinate and an angular coordinate of a polar coordinate system.

Abstract: A method of operating a fastening apparatus includes: a fastening apparatus preparing step of preparing a fastening apparatus including n fastening tools; a first workpiece disposing step of disposing a first workpiece having m fastening holes at one side of the fastening apparatus; a first fastening tool disposing step of disposing each of the n fastening tools above any one of the m fastening holes; and a first storage step of storing, in a control unit, positions of the n fastening tools in the first fastening tool disposing step, in which m is larger than n, and a plurality of first fastening tool disposing steps and a plurality of first storage steps are alternately performed.

Abstract: A cylinder head pallet includes: a base plate; a subplate disposed upwardly of the base plate, spaced apart from the base plate, and having a first surface and a second surface that oppose each other; and a plurality of posts installed on the first surface and the second surface of the subplate to support a cylinder head.
