  "textContent": "Methods and systems for estimating a battery parameter for a rechargeable battery. A sequence of a first zero current period, a first battery measurement of the first battery circuit, delivery of a known quantity of charge to the first battery circuit, a second zero current period, and a second battery measurement is performed. The known quantity of charge may be obtained from various sources. The battery parameter is estimated using an inverted open circuit voltage model, the first and second battery voltage measurements, and the known quantity of charge. The battery parameter may be a battery capacity and/or battery state of health.",
