BATTERIES AND METHODS FOR HANDLING A DETECTED FAULT CONDITION

Abstract:

In accordance with some embodiments, a battery includes a cell and a thermistor coupled to a monitor line and a switch. The monitor line is operable to send signals to the communications device or battery corresponding to a temperature of at least a portion of the battery. A data line is coupled to a decoder. The decoder is coupled to the switch, wherein the decoder is operable to activate the switch, thereby interrupting the thermistor. In accordance with some embodiments, a method includes receiving a fault signal at a data line of the battery, the fault signal indicating that at least a first cell of the communications device battery has been compromised. The method includes interrupting a thermistor by activating a switch coupled to a decoder coupled to the data line, thereby simulating that the temperature of at least a portion of the battery has reached an outer limit.
