A monitoring device for an energy storage device mounted on a vehicle includes: a memory; and a processor, wherein the memory is configured to store at least one of data on an estimated value of a parking-time discharge current, which the energy storage device discharges during parking, and data for calculating the estimated value of the parking-time discharge current. The processor is configured to perform first SOC estimation processing in which an SOC of the energy storage device is estimated by integrating estimated values of the parking-time discharge current based on the data stored in the memory when the vehicle is in a parking state.
