  • Patent number: 11177515
    Abstract: A system for maintaining a fleet of aircraft batteries located at multiple airports. The system may be configured to obtain charge information and battery health information for individual batteries within the fleet of aircraft batteries from charging containers located at individuals ones of the multiple airports. The charge information may include charge statuses of the individual batteries and/or the battery health information may characterize the degradation of the individual batteries over time. The system may determine predictions of one or more batteries to be re-allocated and/or to receive maintenance based on the battery health information. The system may generate a battery management plan including the one or more predictions recommending one or more batteries to be re-allocated and/or to receive maintenance.

  • Patent number: 11165274
    Abstract: The portable, motor-driven alternator for use in recharging a battery is configured for use with a battery. The portable, motor-driven alternator for use in recharging a battery comprises the modified chainsaw, an AC/DC converter, a selectable voltage regulator, a jumper cable, and a diode. The modified chainsaw generates electrical energy. The AC/DC converter converts the electrical energy from an AC voltage to an unregulated DC voltage. The selectable voltage regulator regulates the unregulated DC voltage from the AC/DC converter into a regulated voltage. The selectable voltage regulator generates a voltage level selected from a plurality of voltage levels. The jumper cable transfers the electrical energy from the selectable voltage regulator to the battery. The diode prevents the backflow of electrical energy from the battery into the selectable voltage regulator.

  • Patent number: 11139693
    Abstract: A contactless power transmission apparatus includes a receiver that includes a resonant circuit that receives electric power from a transmitter. The receiver causes, in response to a measurement value of an output voltage of electric power output from the resonant circuit being out of a predetermined allowable range of voltages, a short circuit to short-circuit the resonant circuit and transmits determination information indicating that the contactless power transmission apparatus is not outputting a constant voltage. In response to the determination information, the transmitter in the contactless power transmission apparatus detects a switching frequency of alternating current power to be supplied to a transmitter coil from a power supply circuit at which the contactless power transmission apparatus outputs a constant voltage in accordance with a measurement value of a current through the transmitter coil.
