First Claim
Patent Images
1. A method of detecting whether a battery in an electronic device is counterfeit or defective, the method comprising:
- (a) obtaining an actual battery characteristic profile generated by recording performance of the battery during use of the battery by the device;
(b) retrieving an expected battery characteristic profile corresponding to said actual battery characteristic profile;
(c) comparing said expected battery characteristic profile with said actual battery characteristic profile to determine a value representing an error between said expected battery characteristic profile and said actual battery characteristic profile;
(d) comparing said value to an error threshold; and
(e) taking a responsive action when said value exceeds said error threshold.

Abstract
Systems and methods are disclosed for detecting whether a battery in an electronic device is counterfeit or defective. An actual battery characteristic profile is generated by recording the performance of the battery during use of the battery by the device. This profile is then compared to its corresponding expected characteristic profile. If the profiles are not substantially similar (i.e. if the error between the two curves exceeds a given error threshold), the battery is determined to be counterfeit or defective and responsive action is taken.
