    摘要： An assembly (24) for an aircraft (1000) includes an aircraft electrical distribution bus (66), a battery (70), and a battery monitoring system (72). The battery includes a plurality of battery strings (80). The plurality of battery strings is configured as a main subset (106) and a reserve subset (108). The battery monitoring system further includes a processor (100) in communication with a non-transitory memory (102) storing instructions, which instructions when executed by the processor, cause the processor to electrically connect the reserve subset to the aircraft electrical distribution bus by: determining the bus voltage and the battery string voltage of each battery string of the reserve subset, identifying a threshold voltage range of the reserve subset for electrically connecting the reserve subset to the aircraft electrical distribution bus, where identifying the threshold voltage range is based at least on the bus voltage, and electrically connecting at least one battery string of the reserve subset to the aircraft electrical distribution bus with the bus voltage within the identified threshold voltage range.

    摘要： A power and energy management, PEM, method for managing power consumed by a plurality of power devices on a network, the scheme comprising: a first network monitoring step (S1) to determine whether power and energy management is required based on the power available on the network and the power consumption of the power devices on the network; a status monitor step (S2) to determine the operating status of each of the power devices on the network; a step (S4) of determining a coordination strategy for operating the power devices on the network in response to a determination in the first network monitoring step that power energy management is required; a step (S5) of determining a coordination strategy for recharging of any storage devices on the network in response to a determination in the first network monitoring step that power energy management is not required; and controlling (S6) devices on the network to operate at a power consumption level and/or to recharge based on the above steps.

    摘要： A power and energy management system, PEMS, architecture for managing power consumed by a plurality of power devices on a network, the architecture comprising: one or more local supervisors (11, 12, 13) each arranged to be connected in digital communication with one or more of the power devices (10) on the network; each local supervisor comprising: an input (CONTROL ERROR) to receive a control error signal indicative of a difference between the power consumption of the one or more devices and power available on the network for those devices; a watchdog module (120) configured to receive the control error signal and to determine from the control error signal whether there is a need for PEMS action on the network; a status monitor (130) configured to obtain information as to the operating status of the one or more power devices; a coordinator module (150) configured to define a coordination strategy for operating selected devices of the one or more devices based on the determination from the watchdog module and the information obtained by the status module; and a control action module (160) arranged to provide a set point to selected devices of the one or more devices to operate according to the coordination strategy determined by the coordinator module.

    摘要： An electrical power system (300) including a first plurality of power sources (371) including at least one of a first solar array (304), a first supercapacitor (308), and a first battery (306). The electrical power system further includes a second plurality of power sources (372) including at least one of a second solar array, a second supercapacitor, and a second battery. The electrical power system further includes a first ESMC (311) in electronic communication with the first plurality of power sources. The electrical power system further includes a second ESMC (312) in electronic communication with the second plurality of power sources. The electrical power system further includes a multi-channel DC bus (320) which supplies electric power to a load. The first ESMC supplies electric power to a first channel (321) of the multi-channel DC bus. The second ESMC supplies electric power to a second channel (322) of the multi-channel DC bus.
