Abstract
Recycling of an electrochemical energy storage device is provided. A remaining charge on the electrochemical energy storage device is determined. An impedance profile of the electrochemical energy storage device is determined for the remaining charge. The impedance profile includes an internal impedance of the electrochemical energy storage device at different charge levels from the remaining charge to a complete discharge. A variable discharge load is applied on the electrochemical energy storage device until the complete discharge. The variable discharge load varies with the internal impedance of the electrochemical energy storage device at the different charge levels.
