摘要:
A vehicle includes a body and at least one propulsion unit operatively coupled to the body. The vehicle also includes an electrical power system at least partially disposed within the body. The electrical power system includes a rechargeable battery and a health management unit operatively coupled to the rechargeable battery. The health management unit includes a state of health module configured to output information corresponding to battery health based on received battery-related data. The battery-related data includes data collected in real time operation of the rechargeable battery and battery relevant fault history of the vehicle.
摘要:
Systems and methods for health management of rechargeable batteries are disclosed. In one embodiment, a rechargeable battery system includes a rechargeable battery, and a battery health management unit operatively coupled to the rechargeable battery and including a state of health module configured to estimate a battery health by receiving battery-related data and predicting one or more failure modes. The state of health module may further include a prognostic failure mode component configured to combine at least one flight data variable with at least one model-based prognostic. In alternate embodiments, the battery health management unit may further include a state of life module and a state of charge module.

A fitting and an associated grommet are provided for supporting a conduit penetrating a panel and limiting energy transfer between the conduit and panel. The fitting may include a grommet having annular first and second sections spaced apart from one another and an annular wall extending between the first and second sections such that the wall and first and second sections define a bore. A plurality of ribs protrude from the annular wall, the ribs being distributed circumferentially around the annular wall and spanning between the first and second sections. A tubular liner extends through the bore of the grommet and contacts the first and second sections. The plurality of ribs extend into the bore, and at least some of the ribs contact the liner.

An ice protection system and method are provided that facilitate the prevention or reduction in ice formation upon an aerodynamic surface. The ice protection system may include at least one induction coil spaced apart from an electrically conductive layer of an aerodynamic surface and disposed interior of an exterior surface of the aerodynamic surface. For example, the ice protection system may include a plurality of induction coils with each induction coil being spaced apart from the other induction coils such that the respective induction coils are associated with different portions of the aerodynamic surface. The ice protection system may also include a signal source configured to provide alternating current to the induction coil(s) to thereby generate an electromagnetic field that creates an eddy current in the electrically conductive layer so as to heat the electrically conductive layer.
