Abstract: A system for assuring safe use of a battery pack includes a display unit and a state of health (SoH) monitor connected to the battery pack, the SoH monitor. The SoH monitor a) instructs the SoH monitor to measure terminal voltage of the battery pack at a beginning of a current flow cycle; b) instructs the SoH monitor to measure terminal voltage of the battery pack after completion of the current flow cycle; c) instructs the SoH monitor to successively re-measure terminal voltage of the battery pack after completion of the current flow cycle until one of the successively re-measured terminal voltages is equal to a previous one of the re-measured terminal voltage; d) instructs the SoH monitor to determine and record ampere-hours (Ah) passing through the battery pack during the time period between steps a) and c); e) instructs the SoH monitor to determine SoH of the battery pack as a function of a quotient of a difference between terminal voltages determined in steps a) and c) divided by the Ah determined in step d), and f) instructs the SoH monitor to send the SoH determined in step e) to the display unit for display as an updated SoH of the battery pack. A switch is operable to disconnect the battery pack from the DC power system upon the display unit indicating SoH of the battery pack being below a predetermined value

Abstract: An electrical system for an aircraft with an electric taxi system (ETS), the electrical system may include at least one traction motor, a DC link and at least one traction-motor bidirectional DC-AC converter interposed between the at least one traction motor and the DC link. An engine-driven power source may be configured to provide DC power to the DC link or extract DC power from the DC link. A battery unit may be configured to provide DC power to the DC link or extract DC power from the DC link. An adaptive power controller may be interconnected with the power source, the battery unit and the at least one traction-motor bidirectional DC-AC converter and configured to regulate voltage of DC power delivered to the DC link.
