A battery monitoring apparatus that monitors a temperature of a battery includes a temperature detecting unit, a power supply, a limiting unit, a temperature acquiring unit, and determining unit. The temperature detecting unit is provided for the battery. Resistance of the temperature detecting unit changes with temperature. The power supply applies a voltage to the temperature detecting unit. The limiting unit limits the application of voltage to the temperature detecting unit from the power supply. When the limiting unit is not limiting the application of voltage, the temperature acquiring unit determines the temperature of the battery based on a voltage-drop amount in the temperature detecting unit. When the limiting unit is limiting the application of voltage, the determining unit makes a determination regarding a short circuit between the temperature detecting unit and the battery based on the voltage applied to the temperature detecting unit.
