Patent number: 9157966Abstract: An online method and apparatus for determining state of charge (SoC) and state of health (SoH) of batteries on platforms that present dynamic charge and discharge environments is disclosed. A rested open circuit voltage (OCV) may be estimated online using a battery dynamic model along with measured terminal voltage, current and temperature. The SoC and SoH can then be determined from this estimated OCV. The apparatus and methods may estimate SoC and SoH of a battery in a real-time fashion without the need to a) disconnect the battery system from service; b) wait for a predefined rest time; or c) depolarize the battery.Type: GrantFiled: November 25, 2011Date of Patent: October 13, 2015Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Anki Reddy Papana, Harmohan N.

Patent number: 9013066Abstract: A power management system may employ a power source, a distribution system between the power source and electrical loads and an energy accumulator. The accumulator may comprise a plurality of energy processing blocks. Each block may have a limited number of energy storage cells connected in series to produce first voltage. A second higher output voltage from the accumulator may be achieved though integrated DC-DC, DC-AC and AC-DC conversion with intermediate boost of AC voltage through high frequency transformers. Bidirectional power flow may be achieved with high efficiency during charge and discharge of the accumulator. Secondary windings of the transformers may be connected with one another in series so that the accumulator can transfer energy between the distribution system and any one or all of the energy processing units in a fault-tolerant and efficient manner.Type: GrantFiled: October 28, 2010Date of Patent: April 21, 2015Assignee: Honeywell International Inc.Inventors: Hassan Ali Kojori, Harmohan N.

Patent number: 8350573Abstract: According to the features discussed herein, through a single generalized arc-fault detection algorithm, various types of series and/or parallel arc faults can be detected without any nuisance trip for either AC or DC Electric Power Systems. Running Discrete Fourier Series (RDFS) formulation for nuisance-free operation and cost-effective implementation is developed. Unlike other methods which require numerous source and load-side current and voltage measurements, only source side current is required. An arc detector may include a first detector to monitor variations of a magnitude of a fundamental component of a current, and a second detector to monitor an overload condition based in an i2t calculation.Type: GrantFiled: September 27, 2010Date of Patent: January 8, 2013Assignee: Honeywell International Inc.Inventors: Hassan Ali Kojori, Yang Ye
