Abstract: A battery management device includes a calculating unit that calculates a movable distance based on a state of charge of an energy storage device serving as a power source of the electric moving body. The calculation unit of the battery management device is configured to: acquire a state of charge of the energy storage device; acquire environmental information in a planned route of the electric moving body; calculate, from the acquired state of charge and environmental information, a power consumption amount predicted based on a watt-hour necessary for the electric moving body to move along the planned route and a prediction of a power consumption amount in an installation mounted on the electric moving body; and calculate a movable distance achieved by remaining power of the energy storage device based on the calculated predicted power consumption amount and the state of charge.
