Abstract: An aspect of the present invention is to provide a fluorine-based polymer showing a significantly low dielectric constant of less than 1.8 and a fluorine-based polymer composition including the same. The fluorine-based polymer provided in an aspect of the present invention shows a very low dielectric constant, wherein the polymer is not only a pollution-reducing material generating no harmful substance, but may also be utilized as a coating material in various fields due to high adhesiveness. Furthermore, a polymer film employing the polymer as a material has a volume resistance of about 5.8×1015 Ohmcm, showing an excellent resistance value as an insulating material.

Abstract: An energy storage system of disclosed technology include: a plurality of battery racks, each of the plurality of battery racks structured to support a plurality of battery cells; a management controller configured to be in communication with and to control the battery cells in the plurality of battery racks; and one or more connection lines configured to connect the management controller to the plurality of battery racks to form a network.

Abstract: The present disclosure provides a bush-type mount for a vehicle that has a high degree of freedom of setting of the properties thereof along three axes so as to increase the property thereof in the axial direction (the longitudinal direction of the vehicle) to the level of the property thereof in the radial direction (the vertical direction and the lateral direction of the vehicle) or to increase both the property thereof in the axial direction and the property thereof in the radial direction, thereby sufficiently securing the properties of an entire mount system in all directions irrespective of the direction in which the bush-type mount is disposed.

Abstract: A damper for a drive shaft of a vehicle, which is installed to a predetermined position of the drive shaft for transmitting torque of an engine to a driven wheel, may include a bimetal or a metallic member corresponding to the bimetal; and a hollow body molded of a rubber material to surround the bimetal or the metallic member.
