Abstract

The present invention relates to a voltage recognition system of a starting battery and a method of recognizing an off state of an external system using the same, and more particularly, to a driving system of a starting battery and a method of recognizing an off state of an external system using the same, which make it possible to start an engine next time by recognizing the off state of the external system in an overvoltage state according to whether there occurs a difference between values of voltages measured by two ADCs having different positions of ground GND without requiring a current sensor.
