Abstract

An estimation device is a device that estimates a charge state of an energy storage device including a negative electrode having a negative active material that contains Si. The estimation device includes a control unit that determines based on a charge-discharge history of the energy storage device whether or not to perform a first estimation method of estimating a charge state of the energy storage device by using a relationship between the charge state and a voltage of the energy storage device.
