A measurement apparatus includes a measurement circuit configured to measure a first current that flows to an electricity storage device and a second current that flows from the storage device, and a processor configured to detect one of a first state, in which the storage device is fully charged, and a second state, in which the storage device is fully discharged. The processor is configured to, upon detection of one of the first and second states, control the measurement circuit to start the measurement of the first current and the second current, calculate a remaining amount of power of the storage device using the measured first current and the measured second current, and output the calculated remaining amount of power.
