Abstract: The present disclosure provides a switched reconfigurable multi-converter multi-source energy storage system configuration for electrified vehicles comprising of multiple dc/dc power converters, multiple energy sources, a mode selector switching module further comprising a plurality of controllable switches and a controller. A method of switching to reconfigure the multi-converter multi-source energy storage system during the dynamic events of variable power demand or regeneration in an electrified vehicle is disclosed. Furthermore, a power flow control scheme for executing the dynamic switching methods of reconfiguration to maneuver the flow of power within the system during different scenarios of forward power delivery or reverse power accumulation is disclosed. The controllable switches are methodically activated or deactivated to couple or decouple the energy sources to or from the input side of the dc/dc power converters by means of necessary activation or deactivation signals from the controller.

Abstract: The disclosed technology relates to determining physical zone data within a zoned namespace solid state drive (SSD), associated with logical zone data included in a first received input-output operation based on a mapping data structure within a namespace of the zoned namespace SSD. A second input-output operation specific to the determined physical zone data is generated wherein the second input-output operation and the received input-output operation is of a same type. The generated second input-output operation is completed using the determined physical zone data within the zoned namespace SSD.

Abstract: A method for identifying valid change points includes plotting original timeseries data; plotting a scaled cumulative sum of deviance from a mean applied on the timeseries data for generating a cumulative sum (CUSUM) chart; applying a piecewise linear fit (PWLF) on the CUSUM chart for generating a PWLF segment chart; identifying potential change points on the PWLF segment chart; determining an angle formed at each of the potential change points; comparing the determined angle for each of the potential change points against a reference angle limit; when the determined angle is less than the reference angle limit, discarding a corresponding potential change point, and when the determined angle is greater than the reference angle limit, calculating a significance value for the corresponding potential change point; and identifying a valid change point based on the significance value.

Abstract: A method for predicating a service life of a fuel filter includes causing a fuel pump of a fuel system to direct fuel through a fuel filter of a fuel system. The method also includes receiving work cycle data from machines that implement a same or similar fuel system. The method further includes receiving, via sensors of the fuel system, fuel system data and determining, from the fuel system data, a pressure difference across the fuel filter. The method further includes determining, based on the work cycle data, predicted load cycle data for the fuel system and determining, via a filter life model, a filter service interval representing an amount of time the fuel filter is operable in the fuel system prior to the pressure difference reaching a predetermined value.
