INTELLIGENT BATTERY SENSOR FOR MEASURING ACCURATE CURRENT AND METHOD THEREOF

摘要

PURPOSE: An intelligent battery sensor for accurately measuring a current and a current measuring method thereof are provided to accurately measure a current in a battery by accurately finding a resistance value even though a value of shunt resistance is changed. CONSTITUTION: Shunt resistance(100) measures a current in a battery. A current source(200) is connected to the shunt resistance and supplies a current to the shunt resistance. A resistance value in the shunt resistance is calculated through current supply of the current source. The current in the battery is measured based on the calculated resistance value.
