Abstract: A battery module including a cell assembly having a plurality of battery cells arranged to be stacked on each other; a lower housing having a lower plate provided in a plate form and two vertical plates extending vertically on the lower plate with a predetermined interval, the cell assembly being at least partially inserted into a space between the two vertical plates, so that a plurality of bus bars electrically connected to electrode tabs respectively provided at the battery cells are coupled to the vertical plates; an upper housing coupled to the lower housing to surround an upper portion of the cell assembly; and a sensing unit having a harness wire electrically connected to the plurality of bus bars and provided from a lower portion of the lower housing to an upper portion thereof and a sensing connector connected to an end of the harness wire.

Abstract: Disclosed is a system for determining a protection level. The system includes a receiver configured to receive an error augmentation for a satellite orbit and clock error, an error augmentation for an ionospheric error, an error augmentation for noise and multi-path between a receiver and a satellite, and an error augmentation for a tropospheric error, a first calculator configured to calculate a first adjustment coefficient to be applied to the error augmentation for the satellite orbit and clock error and the error augmentation for the ionospheric error, and a second calculator configured to calculate a protection level by applying the first adjustment coefficient.
