Resumen de: WO2026060526A1
Various embodiments are described herein for a system and method for condition monitoring and detecting and diagnosing faults in electromechanical or electrochemical systems and batteries using a frequency-domain statistical analysis framework. The method comprises receiving raw time-domain signals from one or more sensors monitoring the electromechanical or electrochemical system, applying a Short-Time Fourier Transform to convert the time-domain signals into a spectrogram, and segmenting the spectrogram into a plurality of frequency band segments. Each segment is independently analyzed using Principal Component Analysis based Multivariate Statistical Process Control, followed by statistical smoothing of the MSPC outputs. Fault conditions can be classified based on the smoothed statistical indicators, enabling accurate identification of deviations from baseline behavior.

A battery system with a large-format Li-ion battery powers attached equipment by discharging battery cells distributed among a plurality of battery packs. The discharging of the battery cells is controlled in an efficient manner while preserving the expected life of the Li-ion battery cells. Each battery pack internally supports a battery management system and may have identical components, thus supporting an architecture that easily scales to higher power/energy. Battery packs may be added or removed without intervention with a user, where one of battery packs serves as a master battery pack and the remaining battery packs serve as slave battery packs. When the master battery pack is removed, one of the slave battery packs becomes the master battery pack. Charging and discharging of the battery cells is coordinated by the master battery pack with the slave battery packs over a communication channel such as a controller area network (CAN) bus.

A portable energy storage device capable of simultaneous multi-port discharge and a power allocation method. The energy storage device is equipped with multiple charging output ports, some of which have different preset power allocation priorities. This allows the user to determine the priority sequence of multiple power-receiving according to needs when using the device. The invention ensures that when multiple charging output ports are all connected to power-receiving devices and the sum of power of the power-receiving devices exceeds the maximum power that the device can provide, all ports can still operate at their respective preset minimum power. If there is remaining power, the remaining power is preferentially allocated to the charging output ports with higher priority. When the number of charging output ports connected to power-receiving devices changes, the device reallocates power, achieving dynamic power adjustment and enabling the device to operate at its maximum output power whenever possible.

Resumen de: WO2026064449A1
A method for producing sulfurizcd-carbon cathode materials for electrochemical cells involves mixing carbon nanofibers, sulfur, and a monomer (e.g., acrylonitrile) to form a mixture, polymerizing the monomer to encapsulate the nanofibers and sulfur within a polymer matrix (e.g., polyacrylonitrile), and pyrolyzing the matrix to chemically bond carbon from the polymer to the nanofibers and sulfur, yielding sulfurized-carbon particles fused to the nanofibers. The pyrolyzed material forms a fluffy powder that is compressed into a free-standing dry film, wherein the nanofibers and longer nanofiber yarns create a three-dimensional conductive network enhancing mechanical stability and electrical conductivity. The film is laminated to a current collector to form a cathode. Optional pore- loading with molecular sulfur improves capacity and cycle life, achieving >70% sulfur utilization without wet processing solvents.
