|20120243130||ELECTRIC BATTERY WITH MULTIPLE ELECTRICAL ENERGY GENERATING ELEMENTS - A lithium-based battery system for a vehicle includes a plurality of lithium battery cells arranged in series that provide energy to propel the vehicle. Each of the battery cells includes a first terminal, a second terminal, a plurality of lithium battery elements arranged in parallel, a plurality of disconnect switches, and a shunt switch. Each of the battery elements includes a first terminal and a second terminal. The first terminal of each of the battery elements is connected to the first terminal of the battery cell. The second terminal of each of the battery elements is connected to the second terminal of the battery cell via a corresponding one of the disconnect switches. The shunt switch is connected between the first and second terminals of the battery cell. A control module selectively opens and closes the shunt switches and the disconnect switches.||09-27-2012|
|20120070701||METHOD FOR SECURING THE OPERATION OF AN ELECTRIC BATTERY - The invention relates to a method for securing the operation of an electric battery comprising a plurality of electrical energy-generating elements which are mounted within an electricity production circuit, said method providing for monitoring the occurrence of a malfunction of each of said elements and, in case a malfunction of an element is detected, to actuate a shunting of said defective element so the electrical current no longer crosses through said defective element while maintaining the production circuit closed. The invention also relates to a battery in which such a method can be implemented.||03-22-2012|
