Problems solved by technology

Therefore, if the voltage of the power storage device drops significantly during idling stop, the voltage will drop further due to the voltage drop thereafter, so that sufficient electric power cannot be supplied from the power storage device to auxiliary machines during restart of the engine, and the auxiliary machines may sometimes be damaged. The action of the class becomes unstable

Abstract

The invention provides a power storage device and a method of restarting an engine of an idle stop vehicle. The power storage device (1) supplies power to a starter and an auxiliary engine for starting an engine of an idle stop vehicle, the power storage device (1) being provided with a power storage element (12), a measurement unit (current sensor 51) for measuring a physical quantity relating tothe amount of voltage drop in the power storage element (12), and a management unit (55) for managing the power storage element (12), the management unit (55) performing: estimation processing (S101-S104); estimating the minimum voltage of the power storage element (12) during restart of the engine on the basis of the physical quantity at a given point in time during idle stop; and a notificationprocess (S106) for notifying the idle stop vehicle of a restart request for the engine when the minimum voltage is less than a prescribed threshold value (S105: YES).

Description

technical field [0001] It relates to a power storage device and an engine restart method of an idle-stop vehicle. Background technique [0002] Conventionally, there are known vehicles that perform a so-called idling stop that automatically stops an engine when the vehicle is stopped (hereinafter referred to as an idling stop vehicle). Generally, in an idle-stop vehicle, the power storage device that supplies electric power to the starter that starts the engine is also used to supply power to auxiliary machines (ECU: Engine Control Unit, headlights, air conditioner, etc.) during idle stop. , audio, etc.) power storage device that supplies power. [0003] During idling stop, power is supplied from the power storage device to the auxiliary equipment, but since the engine is stopped, power generation is also stopped. Therefore, the voltage of the power storage device (more specifically, the power storage element included in the power storage device) drops significantly during...
