POWER BANK APPARATUS FOR MEASURING RESISTANCE OF CHARGING LINE
First Claim
1. A power bank apparatus configured to measure resistance of a charging line, the power bank apparatus comprising:
- at least one input port configured to receive from at least one external power supply at least one input power signal as at least one test signal through at least one charging line;
at least one first detection circuit coupled to the at least one input port to receive the at least one test signal, wherein the at least one first detection circuit is configured to detect a voltage of the at least one test signal as at least one no-load voltage if the at least one external power supply is in a no-load state, and the at least one first detection circuit is configured to detect the voltage and a current of the at least one test signal as at least one load voltage and at least one load current if the at least one external power supply is in a load state; and
a processing circuit coupled to the at least one first detection circuit, the processing circuit receiving the at least one no-load voltage, the at least one load voltage, and the at least one load current to calculate the resistance of the at least one charging line.

Abstract
A power bank apparatus configured to measure resistance of a charging line includes an input port, a first detection circuit, and a processing circuit. Through the charging line, the input port is configured to receive from an external power supply an input power signal as a test signal. The first detection circuit receives the test signal. If the external power supply is in a no-load state, the first detection circuit is configured to detect a voltage of the test signal as a no-load voltage. If the external power supply is in a load state, the first detection circuit is configured to detect the voltage and a current of the test signal as a load voltage and a load current. The processing circuit is coupled to the first detection circuit and receives the no-load voltage, the load voltage, and the load current to calculate the resistance of the charging line.
