Battery energy storage system

摘要

In order to provide a charge/discharge technology for controlling an assembled battery system without promoting degradation or reduction in the lifetime of the assembled battery system, the assembled battery system includes a function for controlling charge and discharge power of a plurality of units each including a secondary battery and a power converter as one unit, the plurality of units being electrically connected in parallel to each other. When each unit performs charge or discharge by at least one or more times, charge and discharge of the unit are controlled so as not to be performed until a predetermined pause time period elapses.
