A computer-implemented method enables capacity based pre-charging and age based permanent failure detection in a battery. The method comprises detecting, via a controller, a real time cell voltage for at least one cell in the battery. The controller determines if the real time cell voltage is less than a normal operating cell voltage. In response to the real time cell voltage being less than the normal operating cell voltage, a capacity based pre-charge value is calculated based on a full charge capacity and at least one cell parameter of the cell. A pre-charge time is calculated based on the capacity based pre-charge value. A pre-charge voltage is identified. The battery management controller is triggered to pre-charge the battery using the calculated pre-charge time and the identified pre-charge voltage.

Battery management system and method for charging lithium-ion battery cells in an information handling system

Embodiments of methods for preventing internal short circuits in a lithium-ion battery cell. In an embodiment, a method of manufacturing a lithium-ion battery cell may include providing a cathode, providing an anode, providing a separator disposed between the cathode and the anode, and covering an edge of the cathode to prevent a short between the cathode and the anode through the separator. The method may also include winding the cathode, the anode, and the separator into an electrode roll.
