AI Technical Summary
Technical Problem
Conventional methods for diagnosing battery degradation require full charging and discharging processes, which are time-consuming and inefficient, and lack a straightforward method to assess battery degradation based on voltage and resistance.
Method used
A battery diagnosing apparatus and method that measures open circuit voltage (OCV) and resistance after charging is complete, calculates voltage and resistance deviations, and analyzes voltage-resistance ratios to determine degradation acceleration without full discharge.
Benefits of technology
Enables rapid and convenient diagnosis of battery degradation by analyzing voltage and resistance deviations, reducing the need for full charging and discharging processes and allowing for quick identification of degradation patterns.
