Title
(EN) MANAGEMENT DEVICE AND POWER STORAGE SYSTEM
Abstract
(EN)

A management device (50m) manages a plurality of power storage devices (10 to 40) interconnected in parallel. In the management device (50m), a halt controller (541m) halts an operation of at least one of the plurality of power storage devices (10 to 40) during a period in which charged/discharged power between the plurality of power storage devices (10 to 40) and a load (2) is less than a set value. During the period in which the charged/discharged power is less than the set value, for example, the halt controller (541m), by turns, halts an operation of one of the plurality of power storage devices at a set time interval.
