July 23, 2014



By a News Reporter-Staff News Editor at Electronics Newsweekly -- According to news reporting originating from Washington, D.C., by VerticalNews journalists, a patent application by the inventor Peswani, Sanjay (Canton, MI), filed on December 30, 2012, was made available online on July 10, 2014.

No assignee for this patent application has been made.

Reporters obtained the following quote from the background information supplied by the inventors: "A battery pack having a plurality of battery cells therein has been utilized to provide power for an electric vehicle. However, if an amount of power extracted from the battery pack exceeds a desired amount of power, the operation of the battery pack can be degraded.

"Accordingly, the inventor herein has recognized a need for a system and a method for derating a power limit associated with a battery pack that minimizes and/or eliminates the above-mentioned operational issue."

In addition to obtaining background information on this patent application, VerticalNews editors also obtained the inventor's summary information for this patent application: "A system for derating a power limit associated with a battery pack in accordance with an exemplary embodiment is provided. The system includes a battery pack voltage sensor configured to measure a first battery pack output voltage of the battery pack at a first time. The system further includes a microprocessor programmed to operably communicate with the battery pack voltage sensor. The microprocessor is further programmed to determine an initial power limit of the battery pack based on at least one operational parameter of the battery pack. The microprocessor is further programmed to determine whether the first battery pack output voltage is greater than a threshold battery pack voltage. The microprocessor is further programmed to determine a first power limit of the battery pack that is less than the initial power limit, if the first battery pack output voltage is greater than the threshold battery pack voltage. The microprocessor is further programmed to transmit a first message having the first power limit on a communication bus.

"A method for derating a power limit associated with a battery pack in accordance with another exemplary embodiment is provided. The method includes determining an initial power limit of the battery pack based on at least one operational parameter of the battery pack utilizing a microprocessor. The method further includes determining whether a first battery pack output voltage of the battery pack at a first time is greater than a threshold battery pack voltage, utilizing the microprocessor. The method further includes determining a first power limit of the battery pack that is less than the initial power limit if the first battery pack output voltage is greater than a threshold battery pack voltage, utilizing the microprocessor. The method further includes transmitting a first message having the first power limit on a communication bus utilizing the microprocessor.
