ABSTRACT:
In accordance with the invention, there is a battery defect detection method comprising applying a current ramp to a battery; determining a first time (t1) when a current of the battery reaches a maximum current (Ipeak), and determining a second time (t2) when a terminal voltage of the battery reaches a maximum voltage (Vpeak). The method also includes determining a differential (d), wherein (d)=/(t1)−(t2)/, and wherein (d) corresponds to a magnitude of defects in the battery.
