    • A power management system includes a first power line, a second power line, a first parallel protector, a second parallel protector, a third parallel protector, a first current sensor, a second current sensor, a third current sensor, and a processor. The first parallel protector is coupled to the first power line. The second parallel protector is coupled to the first parallel protector and the second power line. The third parallel protector is coupled to the first parallel protector and a ground terminal. The first current sensor, the second current sensor and the third current sensor respectively sense a first current flowing through the first parallel protector, a second current flowing through the second parallel protector, and a third current flowing through the third parallel protector. The processor detects a surge discharging path according to the first current, the second current and/or the third current.
