A vehicle includes a power storage device (150) for driving the vehicle, a charging inlet (270) for receiving electric power from a power supply (402) provided externally to the vehicle, a charging circuit (294) for charging the power storage device (150) with the electric power from the power supply (402), and an electric power line (281, 282) for connecting the charging inlet (270) and the charging circuit (294). An abnormality detection apparatus for the vehicle includes a voltage application circuit (293) for applying a test voltage to the power line (281, 282), and an ECU (170) as a short circuit detection unit. The ECU (170) detects short circuit of the power line (281, 282) when a voltage value (VH, VC) of the power line (281, 282) is out of a predetermined normal range including a value of the test voltage, while the voltage application circuit (293) applies the test voltage to the power line (281, 282). The ECU (170) determines, based on the voltage value (VH, VC) of the power line (281, 282), which of a plurality of short circuit modes corresponds to the detected short circuit.
