Abstract
(EN) Systems and methods for monitoring a state of charge of a battery are disclosed. An updated state of charge of the battery may be determined based on a measured terminal voltage of the battery, a measured current of the battery, and a value of at least one battery parameter selected from a plurality of values based on a prior state of charge of the battery.
