1. A temperature measuring apparatus for measuring a temperature of a battery pack, comprising:
a first resistor connected between a first power supply and a first node;
a second resistor connected between a second node and a second power supply;
a temperature-variable resistive element connected between the first node and the second node, wherein a resistance of the temperature-variable resistive element varies depending on a temperature of the temperature-variable resistive element; and
a processor configured to:
receive a first voltage input from the first node;
measure a first temperature based on the first voltage input;
receive a second voltage input from the second node;
measure a second temperature based on the second voltage input; and
determine a temperature of the battery pack based on at least one of the first temperature or the second temperature.
