Publication number: 20140103726Abstract: Methods and systems for controlling power conversion systems. In one aspect, a power management system includes a first power conversion system coupled to a first energy source and a second power conversion system coupled to a second energy source, and a control system. The control system causes, while the first power conversion system is operating in an active mode and the second power conversion system is operating in a standby mode, the second power conversion system to exit the standby mode, the second power conversion system providing a reactive power flow upon exiting the standby mode. The control system causes the first power conversion system to provide a compensatory reactive power flow to compensate for at least a portion of the reactive power flow from the second power conversion system.Type: ApplicationFiled: October 12, 2012Publication date: April 17, 2014Applicant: XTREME POWER INC.Inventor: Eric Martin

Patent number: 8471520Abstract: A power delivery rate from a renewable power source to a load is managed by determining, by processing circuitry, a change in a power generation rate, determining, by the processing circuitry, whether the change in the power generation rate exceeds a limit, and then, adjusting, by control circuitry, a power transfer rate to or from a power storage device, such that the adjusting is sufficient to prevent the power delivery rate from exceeding the limit.Type: GrantFiled: May 4, 2010Date of Patent: June 25, 2013Assignee: Xtreme Power Inc.Inventors: Carlos James Coe, Aeron Neils Hurst, Mark Isaac Hardin, Matthew Clayton Such, Richard Thomas Jennings

Patent number: 8237407Abstract: A battery pack connection scheme is shown that provides an synchronized DC environment for every cell in the pack, such that every cell in the same or similar voltage level in the pack sees exactly the same voltage and current environment. In some embodiments, a pack is provided having a positive load connection terminal and multiple batteries connected in parallel to the terminal. The connections are made via respective conductive paths each including a high-power DC precision cable segment, each of the conductive paths having a resistance suitable to allow an average charge acceptance rate of the battery pack to be greater than a one-hour, or “C1”, charge rate. The precision cable segments preferably have matching impedances, or have matching DC resistances.Type: GrantFiled: October 12, 2006Date of Patent: August 7, 2012Assignee: Xtreme Power Inc.Inventors: Aeron Hurst, Carlos Coe, Mark Hood

Patent number: 8198759Abstract: A battery pack connection scheme is shown that provides an optimum DC environment for every cell in the pack, such that every cell in the same or similar voltage level in the pack sees exactly the same voltage and current environment. In some examples, a portable pack is provided having a positive load connection terminal and multiple batteries connected in parallel to the terminal. Connections are made with segments preferably have matching impedances, or have matching DC resistances, creating a uniform DC environment. Portable pack designs are provided including chargers and inverters connected in the uniform DC environment.Type: GrantFiled: November 25, 2008Date of Patent: June 12, 2012Assignee: Xtreme Power Inc.Inventors: Aeron Hurst, Carlos Coe, Charles Moyer, Grant Randall, Lupe Carranco

Publication number: 20100201320Abstract: Discharging a battery is accomplished by: applying an electrical stimulus to the battery; measuring a response to the electrical stimulus, the measured response providing an indication of discharge efficiency of the battery; determining a target frequency corresponding to a maximum discharge efficiency; and then discharging the battery with a discharge current profile comprising current pulses having a frequency component selected based on the determined target frequency.Type: ApplicationFiled: February 9, 2010Publication date: August 12, 2010Applicant: XTREME POWER, INC.Inventors: Carlos Coe, Aeron Hurst
