    Abstract: An expedited preflight readiness system for aircraft includes a power source having one or more battery modules for storing electrical power. An integrated controller is electrically and communicatively coupled with the power source for monitoring and controlling the power source to provide electrical power to aircraft subsystems. A mobile device is communicatively coupled with the integrated controller for communicating instructions to the integrated controller for initiating preflight readiness of the aircraft and for monitoring preflight readiness. A method for preconditioning an aircraft includes determining a state-of-charge of an APU and activating an environmental control subsystem for preconditioning the aircraft by adjusting a current temperature according to a preconditioning profile based on one or more of a target temperature, a target time, the current temperature, an outside air temperature, an amount of energy, and a state-of-charge of the APU.

    Abstract: An internal battery heating system includes an electrical conversion device electrically coupled to an electrochemical sub-cell or battery modules to form a heating circuit. The electrical conversion device alternately raises and lowers a voltage of the heating circuit to drive current between the heating circuit and the electrochemical sub-cell or battery modules. A controller commands the electrical conversion device to cyclically charge and discharge the electrochemical sub-cell or battery modules for internally heating the battery modules. Alternatively, a battery module may be electrically coupled to electrochemical sub-cells via pairs of switches to form a heating circuit. The pairs of switches are adapted for switching the heating circuit alternately between a parallel arrangement and a series arrangement to alternate charging and discharging of the battery module which results in internal heating of the battery module.

    Abstract: A battery module includes a monoblock comprising one or more battery cells, a first power path electrically coupled to the monoblock and electrically couplable to one or more terminals, a switching device coupled to the first power path and configured to open and to close a circuit thereof, a control system that controls the switching device, and a second power path electrically coupled to the monoblock. The second power path is configured to provide power to the control system. An absence of a voltage signal from the second power path detected by the control system causes the switching device to open to electrically disconnect the one or more terminals of the first power path. Detection of the voltage signal from the second power path by the control system may cause the switching device to close to electrically connect the one or more terminals of the first power path.
