Patent number: 9475481Abstract: A powertrain includes a motor-generator and an auxiliary electric system. The powertrain also includes a first energy storage device disposed in a parallel electrical relationship with a motor-generator and an auxiliary electric system. Additionally, the powertrain includes a first switching device selectively transitionable between a first open state to electrically disconnect the first energy storage device from at least one of the motor-generator and the auxiliary electric system, and a first closed state to electrically connect the first energy storage device to at least one of the motor-generator and the auxiliary electric system. The motor-generator and the auxiliary electric system are operable regardless of the first switching device being in the first open and closed states.Type: GrantFiled: May 16, 2016Date of Patent: October 25, 2016Assignee: GM Global Technology Operations LLCInventors: Alan G. Holmes, Venkata Prasad Atluri, Chandra S. Namuduri, Robert S. Conell, Michael G. Reynolds, Thomas Wolfgang Nehl, Bob R. Powell, Madhusudan Raghavan

Patent number: 9370992Abstract: A powertrain for a vehicle is disclosed. The powertrain includes an engine, a motor-generator and a starter mechanism. The powertrain also includes a first energy storage device disposed in a parallel electrical relationship with a motor-generator and an auxiliary electric system. Additionally, the powertrain includes a first switching device selectively transitionable between a first open state to electrically disconnect the first energy storage device from at least one of the motor-generator and the auxiliary electric system, and a first closed state to electrically connect the first energy storage device to at least one of the motor-generator and the auxiliary electric system. Electrical communication between the motor-generator and the auxiliary electric system is independent of the first switching device being in the first open and closed states.Type: GrantFiled: March 13, 2014Date of Patent: June 21, 2016Assignee: GM Global Technology Operations LLCInventors: Alan G.

Patent number: 9281703Abstract: Methods and systems for depowering a rechargeable battery in a rapid, yet controlled, manner. The methods comprise (i) providing a depowering medium comprising expanded graphite (and optionally, one or more dispersible non-ionic electric conductors) dispersed in a substantially non-ionic aqueous medium; (ii) contacting terminals of the battery with the depowering medium; and (iii) maintaining contact between the depowering medium and terminals for a period of time sufficient to depower the battery. The systems comprise (i) the depowering medium; and (ii) a container configured to receive a battery and the depowering medium such that the battery body is contacted with the depowering medium prior to the terminals.Type: GrantFiled: December 5, 2012Date of Patent: March 8, 2016Assignee: GM Global Technology Operations LLCInventors: Mahmoud H. Abd Elhamid, Tao Xie, Tao Wang, Ramona Y. Ying, Robert S. Conell
