Abstract: The present invention provides a high voltage battery rack, including: a plurality of battery modules electrically connected with each other; and a rack controller configured to control the plurality of battery modules, wherein each of the plurality of battery modules comprises: external terminals; and an MSD module configured to determine whether a voltage is applied to the external terminals during operation.

Abstract: A rack BMS detects a ground fault through a circuit embedded therein, and as a master BMS is configured to disconnect all the connections between battery racks and a grid in the case in which the rack BMS detects the ground fault, no more current flows through chassis, thereby protecting the battery racks and ensuring safety of a person using the battery racks.

Abstract: The present invention provides a battery rack including: a housing; a plurality of battery modules stacked in the housing; and a connection member configured to electrically connect the plurality of battery modules, wherein each of the plurality of battery modules includes a plurality of battery submodules stacked on each other, and each of the plurality of battery submodules comprises: at least one cooling member; and a plurality of battery cells located on both sides with the at least one cooling member interposed therebetween, wherein at least two of the plurality of battery cells are located on each of both sides of the at least one cooling member.

Abstract: According to the present invention, a dummy terminal is provided on a sensing substrate and sensing substrate may be thus commonly used on both side surfaces of a battery module, and as a result, since only one type of sensing substrate provided with the dummy terminal needs to be manufactured instead of manufacturing two types of sensing substrates having different arrangements of the substrate terminals, mass productivity of the sensing substrate and the battery module including the same may be significantly improved.

Abstract: A space-fed, flat, reflectarray antenna apparatus for providing a desired degree of phase shift to a received electromagnetic wave to form a narrow beamwidth signal. The reflectarray antenna, in one form, is provided as a dual reflection antenna having a polarization sensitive subreflector and a reflectarray element spaced apart from the subreflector. The reflectarray element includes a large plurality of independent patch antenna units which each form antenna cells. Each patch antenna unit includes a vertical polarization sensitive antenna, a horizontal polarization sensitive antenna and a microstrip transmission line conjoining the two antennas. The microstrip transmission line of each antenna unit has a predetermined length intended to provide a predetermined degree of phase shift.
