Abstract
Systems, methods, and computer-readable media are disclosed for state of charge estimation using battery voltage. The device may determine a first value indicative of a battery voltage during a first time interval, determine a second value indicative of an open circuit voltage of the battery during the first time interval, and determine a third value indicative of a battery temperature during the first time interval. The device may determine, using the second value and the third value, a fourth value indicative of battery resistance during the first time interval, determine, using the first value, the second value, and the fourth value, a first estimated current associated with the battery, and determine a first estimated state of charge value of the battery using the first estimated current.
