Patent ID: 6867595

Claim:
A verification system for verifying authenticity of a battery used in a portable electronic device, the system comprising: a battery for supplying a first electrical current, the battery comprising a transducer for inducing an analog voltage based on the fist electrical current; and a portable electronic device having the battery removably installed therein, the portable electronic device comprising: an analog-to-digital converter (ADC) electrically connected to the transducer for converting the analog voltage to a digital voltage value; a lookup table for providing an expected voltage value based on an operating state of the portable electronic device; and a controller for reading the expected voltage value from the lookup table based on the operating status of the portable electronic device, comparing the expected voltage value with the digital voltage value provided by the ADC, and determining whether the battery is authorized for use in the portable electronic device according to the expected voltage value and the digital voltage value.
