Patent number: 10048320Abstract: System and methods for estimating a future power capability of a battery system included in a vehicle are presented. In some embodiments, a method for estimating a future power capability of a battery system may include determining an initial battery voltage when the battery operates at a current limit and estimating a future battery current at a first time when the battery operates at the associated voltage limit based on the initial battery current. A future battery voltage at the first time when the battery operates at the associated current limit may be determined based on the initial battery voltage. An estimated voltage-limited power capability of the battery at the first time may be determined based on the future battery current and an estimated current-limited power capability of the battery at the first time may be determined based on the future battery voltage.Type: GrantFiled: June 12, 2015Date of Patent: August 14, 2018Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Patrick Frost, Brian J. Koch, Patricia M. Laskowsky, Ashley McAllister

Patent number: 9190853Abstract: Methods and systems for adjusting the voltage limits of a battery. In some implementations, voltage data may be received from each of a plurality of battery sections of a vehicle battery. A voltage offset for the vehicle battery may be calculated using the voltage data. The voltage offset may be calculated by determining a difference between an average voltage taken from each of the plurality of battery sections and at least one of a minimum voltage of all of the battery cells and an average cell voltage from a battery section having the lowest average cell voltage. The voltage offset may be applied to dynamically adjust a voltage limit associated with the vehicle battery so as to prevent any of the battery cells in the vehicle battery from exceeding the voltage limit.Type: GrantFiled: July 25, 2013Date of Patent: November 17, 2015Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Kurt M. Johnson, Robert C. Baraszu, Zachary D. Bylsma, Ashley McAllister, George Robison

Patent number: 9065278Abstract: Systems and methods for estimating the relative capacity of individual battery subdivisions in a battery system are presented. In some embodiments, a system may include calculation system configured to analyze the electrical parameters to generate derivative values of the parameters over a period of time. The calculation system may further calculate summation values associated with individual battery subdivisions based upon the derivate values. A battery control system may utilize the summation values to generate one or more commands configured to control an aspect of an operation of the battery pack based on using the summation values. The summation values associated with battery subdivisions may be used to determine a relative capacity for storing electrical energy, according to some embodiments. The determination of relative capacity may be used by a control system to prevent over-discharge of a battery subdivision having the lowest energy storage capacity.Type: GrantFiled: January 22, 2013Date of Patent: June 23, 2015Assignee: GM Global Technology Operations LLCInventors: Robert C.
