Abstract
Systems and methods for diagnosing battery voltage misreporting is described. According to various embodiments, battery voltage may be monitored with respect to a state of charge and/or time. Based on this monitored information, battery charge state data may be generated by computing time derivatives of the monitored battery voltage across a voltage range. This battery charge state data may be compared with an expected set of charge state data if substantial differences exist, an error may be generated. Other embodiments are described and claimed.
