AI Technical Summary
Existing technologies struggle to quickly and non-destructively determine whether lithium precipitation occurs on the surface of a battery's negative electrode, which can lead to battery degradation, internal short circuits, and potential ignition or explosion.
A battery state estimating apparatus and method that analyzes voltage, current, and temperature changes during charging processes to detect abnormal behaviors indicative of lithium precipitation, allowing for rapid judgment and control of battery usage.
Enables quick, non-destructive detection of lithium precipitation based on charging process measurements, preventing accidents like fires or explosions by promptly stopping the use of affected batteries.
