  "textContent": "A battery management system according to the present disclosure includes a current sensor to measure a battery current which is an electric current flowing through a battery, a voltage sensor to measure a battery voltage which is a voltage across the battery, and a control circuit. When the control circuit receives a key-on signal during a first rest period of the battery, the control circuit determines a fixed rest time, a fixed Open Circuit Voltage (OCV) and a fixed State Of Charge (SOC), and determines an integrated current value of the battery current during a cycle period of the battery. When the control circuit receives a key-off signal during the cycle period, the control circuit starts a second rest period of the battery. The control circuit determines an interest SOC corresponding to an interest OCV which is the battery voltage during the second rest period. The control circuit determines a State Of Heath (SOH) of the battery based on the fixed SOC, the integrated current value and the interest SOC.",
