Battery management system (BMS) and driving method thereof

A method of driving a Battery Management System (BMS), the method comprising the steps of:

• detecting a State of Charge (SOC) reset point;
• integrating a measured battery current until a current integration value corresponding to the SOC reset point reaches a battery capacity rating in response to an SOC reset condition reaching the SOC reset point and a reset operation being required;
• comparing a current integration result and the battery capacity rating;
• and
• determining that a battery is being overcharged in response to the current integration result being equal to the battery capacity rating.

A Battery Management System (BMS), comprising:

• detecting means for detecting a State of Charge (SOC) reset point;
• integrating means for integrating a measured battery current until a current integration value corresponding to the SOC reset point reaches a battery capacity rating in response to an SOC reset condition reaching the SOC reset point and a reset operation being required;
• comparing means for comparing a current integration result and the battery capacity rating;
• and
• determining means for determining that a battery is being overcharged in response to the current integration result being equal to the battery capacity rating.
