Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Counterfeit and defective batteries pose risks to portable electronic devices and users due to their non-compliance with safety and performance standards, as they often lack essential safety features and do not meet operational specifications, potentially causing damage or bodily injury.
Innovation Solution
A method and system for detecting counterfeit or defective batteries by comparing actual characteristic profiles generated during use with expected profiles, using a mobile device's processor and memory to analyze performance data and determine if the battery meets specified conditions, with the option to notify the user or take appropriate action if discrepancies are found.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If counterfeit batteries are used to reduce cost, then device cost is reduced, but safety and reliability deteriorate
Solution Approach 1:
The system performs preliminary detection of battery authenticity and condition before the battery is used in the device. By analyzing characteristic profiles (voltage, current, temperature, impedance) during charging and discharging cycles, the system identifies counterfeit or defective batteries before they can cause safety hazards, allowing preventive action to be taken.
Solution Approach 2:
The system continuously monitors battery performance parameters and compares actual characteristic profiles against expected profiles for authentic batteries. This feedback mechanism allows real-time detection of deviations that indicate counterfeit or defective batteries, enabling the system to respond appropriately to maintain safety while managing cost risks.

3Measurement precision
If temperature monitoring is used to detect unauthorized batteries, then detection accuracy is improved, but device complexity increases
Solution Approach 1:
The system uses existing battery management components (charging circuitry, temperature sensors, microcontroller) to perform multiple functions: normal battery charging, temperature monitoring, and authenticity detection. By making these existing components multi-functional, the system achieves improved detection accuracy without significantly increasing device complexity.
Solution Approach 2:
The system continuously monitors battery performance parameters and compares actual characteristic profiles against expected profiles for authentic batteries. This feedback mechanism allows real-time detection of deviations that indicate counterfeit or defective batteries, enabling the system to respond appropriately to maintain safety while managing cost risks.

AI summary
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.
