ENERGY STORAGE APPARATUS AND RESTART METHOD FOR ENGINE OF IDLING-STOP VEHICLE

摘要

An energy storage apparatus for supplying electric power to auxiliaries and a starter that starts an engine of an idling-stop vehicle, the energy storage apparatus including: an energy storage device; a measurement part (current sensor) that measures a physical quantity relating to a voltage drop of the energy storage device; and a management part that manages the energy storage device. The management part executes an estimation process of estimating, based on the physical quantity, a minimum voltage of the energy storage device during restart of the engine at a predetermined time point during idling-stop of the idling-stop vehicle, and a notification process of notifying a restart request for the engine to the idling-stop vehicle when the minimum voltage is less than a predetermined threshold.
