Abstract: System and methods for estimating a state if a fuse are presented. In some embodiments, the disclosed systems and methods may be utilized in connection with estimating a state of a fuse associated with a manual service disconnect associated with an energy storage system included in a vehicle. Consistent with embodiments disclosed herein, a current event counting-based method utilizing one or more weighted time data buckets associated with various current levels may be used in connection with estimating MSD fuse life. In some embodiments, a MSD fuse end-of-service life signal may be triggered when a total time associated in the weighted time data buckets exceed a threshold value.

Abstract: A battery mounting system for a vehicle including a mounting member configured to connect to an underbody. The mounting member includes a first end, a second end, a first side, and a second side. The second end is opposite to and spaced from the first end along a first axis and the second side is opposite to and spaced from the first side along a second axis that is orthogonal to the first axis. A cross-member extends between the first side and the second side. The cross-member forms a first battery module zone and a second battery module zone. The second battery module zone being spaced from the first battery module zone along the first axis. A first battery module is arranged in the first battery module zone below the vehicle underbody and a second battery module is arranged in the second battery module zone below the vehicle underbody.
