System and method for information handling system battery charge protection and fault alarm |
摘要 |
An information handling system battery has first and second protective circuits to detect and address faults for a first charge applied from an external power source to an integrated charger and a second charge applied from a charger of an information handling system to battery cells. If the first protective circuit detects a fault associated with the integrated charger, charging of the battery cells is still supported by inserting the battery in an information handling system. If the second protective circuit detects a fault, the battery becomes inoperative by disconnecting the battery cells. An indicator, such as LEDs on the battery casing, indicates whether a soft or hard fault has occurred.
