    Abstract: Provided is a device including an acquisition unit configured to obtain a time taken for a voltage level of a battery in a charge mode to change for each of a plurality of voltage sections, and a prediction unit configured to predict a state of health (SOH) of the battery based on ratio information determined by comparing the time obtained for each of the plurality of voltage sections with a reference time for each of the plurality of voltage sections. When the time taken for some voltage sections of the plurality of voltage sections is obtained by the acquisition unit, the prediction unit corrects the predicted SOH of the battery based on the time taken for the voltage level of the battery in a discharge mode to change.

    Abstract: The present invention relates to a packing system including a transporting device, an erecting device, and a guiding device. The packing system is configured to reduce the number of a packing process and to simplify the packing process, thereby improving production efficiency, compared with a conventional system. The packing system is configured to minimize wrinkling of a packing material and to adjust position of ends of the packing material in a way that the packing material is always supplied to a predetermined position, thereby reducing a failure rate of a packed product. It is possible to pack various sizes of packing target objects using a single system.

    Abstract: A flow frame for a redox flow battery includes: a frame body having a plate-like shape and an electrode hole in its center where an electrode is to be disposed; four through holes disposed at corners of the frame body, respectively; a flow channel disposed at a front of the frame body above and below the electrode hole so that two of the through channels diagonal to each other as a pair are connected to each other via the electrode hole; through channels disposed at distal ends of the flow channel to cause electrolyte flows toward a rear of the frame body; and a distribution channel connecting the through channels with the electrode hole at the rear of the frame body. The flow channel has at least one branch point, and a change in cross sectional area of the flow channel before and after the branch point is 10% or less.
