20090115420 | METHOD AND SYSTEM FOR DETERMINING A STATE OF CHARGE OF A BATTERY - Methods and systems are provided for determining a state of charge of a battery. A magnetic force between the battery and a magnet is detected. The state of charge of the battery is determined based on the detected magnetic force. | 05-07-2009 |
20090140742 | METHOD AND SYSTEM FOR DETERMINING A STATE OF CHARGE OF A BATTERY - Methods and systems are provided for determining a state of charge of a battery. The battery is subjected to a predetermined magnetic field such that the battery and the predetermined magnetic field jointly create a resultant magnetic field. The resultant magnetic field is sensed. The state of charge of the battery is determined based on the resultant magnetic field. | 06-04-2009 |
20110166811 | METHOD AND SYSTEM FOR DETERMINING A STATE OF CHARGE OF A BATTERY - Methods and systems are provided for determining a state of charge of a battery. The battery is subjected to a predetermined magnetic field such that the battery and the predetermined magnetic field jointly create a resultant magnetic field. The resultant magnetic field is sensed. The state of charge of the battery is determined based on the resultant magnetic field. | 07-07-2011 |
20120161757 | METHOD AND SYSTEM FOR DETERMINING A STATE OF CHARGE OF A BATTERY - Methods and systems are provided for determining a state of charge of a battery.

20120315531 | BATTERY CELL CONNECTION APPARATUS - A battery component includes electrochemical cells with positive and negative terminals of different metals within a sealed enclosure. A positive terminal and a negative terminal of substantially the same material extend outside the sealed enclosure. The battery component provided enables battery construction which reduces or eliminates exposed welds of different metals. A battery assembly with exposed interconnecting members of the same metal is also provided. | 12-13-2012 |
20130147435 | COST-EFFECTIVE RELIABLE METHOD TO DEPOWER RECHARGEABLE ELECTRIC BATTERIES - 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. | 06-13-2013 |
