摘要： A fuel gauge system for measuring the amount of current in a battery is provided. The fuel gauge system includes a first resistive element connected in series to the battery, a second resistive element connected in series to the first resistive element, a first switch connected in parallel to the second resistive element to control a current flowing in the second resistive element, a second switch connected in series to the second resistive element to control the current flowing in the second resistive element, a controller configured to output a first switching signal to the first switch and output a second switching signal to the second switch, and a fuel gauge circuit configured to measure a battery current flowing in the first resistive element and the second resistive element.
