Patent ID: 8390249

Claim:
A battery comprises: a positive terminal; a negative terminal; one or more rechargeable cells operably coupled to the positive terminal and to the negative terminal; a voltage sensing circuit operable to determine a voltage of the one or more rechargeable cells; and a radio frequency identification (RFID) tag that includes: a transceiver section having a coil integrated into at least one of the positive terminal and the negative terminal, wherein the coil transceives electromagnetic signals within a given frequency band and, at direct current (DC), is a conductive element of the at least one of the positive terminal and the negative terminal; memory for storing battery information and battery charging parameters; and a processing module operable to: obtain the voltage; determine battery charging requirements based on at least one of the voltage, the battery charging information, and the battery charging parameters; and communicate the battery charging requirements via the transceiver section.
