Abstract: A battery tray having multiple insertion holes into which charge/discharge terminals are inserted and multiple heat dissipation holes for air flow are formed at the bottom of a housing in which the batteries are accommodated. Heat can smoothly flow through the heat dissipation holes, and even if there is a difference in the location where the battery is accommodated depending on the center or the outer edge of the tray, the temperature deviation is reduced.

Abstract: A high temperature aging system includes a battery cell tray stack having a structure in which battery cell trays are stacked in multiple stages therein, one or more tray racks located inside a high temperature aging chamber and each including a grid-shaped storage space in which the battery cell tray stack is located, a stacker crane configured to transport the battery cell tray to the grid-shaped storage space, a thermal imaging camera installed on the stacker crane configured to acquire thermal image temperature data on the battery cell trays loaded in the grid-shaped storage space, and a controller configured to control a temperature inside the high temperature aging chamber on the basis of the thermal image temperature data.

Abstract: The present technology relates to a spatial address-based management system, and the management system includes a spatial address-related information reception part configured to receive spatial address-related data assigned to each of segments generated by dividing a workspace into a plurality of rows and columns, a controller configured to process the spatial address-related data received from the spatial address-related information reception part and transmit the processed data to a spatial address-related data storage part, and the spatial address-related data storage part configured to store the spatial address-related data transmitted from the controller as spatial address data, wherein the spatial address data includes information on a unique position of the spatial address, information on a workpiece that is placed at the spatial address, and information on attributes or properties of the spatial address.

Abstract: The present specification relates to an optical film including a transparent base; an anti-static primer layer provided on at least one surface of the transparent base, and including a binder resin including a sulfonic acid polyester acryl-based resin and an anti-static material; and a surface treatment coating layer provided on the anti-static primer layer, and a polarizing plate including the same.
