Abstract
A battery management system and a driving method include a first switch coupled to an end of a resistor. When calculating an internal resistance of a battery, the first switch is turned on and the battery and the resistor are coupled in parallel. Then, the internal resistance of the battery is calculated by using a second current flowing to the battery and a first current flowing to the resistor.
