Abstract:
In one or more embodiments, an information handling system may include an embedded controller, communicatively coupled to a battery system that is configured to power the information handling system. The embedded controller may be configured to: receive a cycle count from the battery system; determine that the cycle count is above a threshold; query the battery system for an expected margin of error, in response to determining that the cycle count is above the threshold; receive the expected margin of error from the battery system; determine that the expected margin of error is within a range; and in response to determining that the expected margin of error is within the range, compute a condition metric of the battery system based on a prediction of a capacity of the battery system and a design capacity of the battery system and store the condition metric of the battery system.
