  "textContent": "Disclosed is a current measuring apparatus and method, and a battery pack including the current measuring apparatus. The current measuring apparatus includes: a switching circuit installed on the charging and discharging path; a current measuring unit having a shunt resistor installed on the charging and discharging path and configured to output a current signal corresponding to a voltage across the shunt resistor; a voltage measuring unit configured to measure the voltage across the switching circuit; a temperature measuring unit configured to measure a temperature of the switching circuit; and a control unit. The control unit determines a first current value indicating a current flowing through the shunt resistor, based on the current signal. The control unit determines a second current value indicating a current flowing through the switching circuit, based on the measured voltage and the measured temperature. The control unit determines whether the shunt resistor is in a normal state, based on the first current value and the second current value.",
