Title: ESTIMATING DEVICE, ELECTRICITY STORAGE DEVICE, AND ESTIMATING METHOD
Abstract:
This estimating device for estimating the state of charge (SOC) of an electricity storage element 31 is provided with a current measuring unit 41, an estimating unit 50, and a modifying unit 50. The estimating unit 50 executes: an estimating process of estimating the SOC of the electricity storage element 31 by integrating the current measured by the current measuring unit 41; and, if a prescribed correction condition has been reached, a correction process of correcting an error in the estimated value of the SOC by charging the electricity storage element 31 to full charge or close to full charge. The modifying unit 50 modifies the correction condition in accordance with the state of the electricity storage element 31.
