A secondary battery system includes plural batteries individually controllable for charging/discharging, plural PCSs each connected to the corresponding battery and performing charging/discharging to the connected battery, and a battery controller distributing a charge/discharge power value as a whole system to each of the PCSs at a fixed cycle or an arbitrary timing. The battery controller includes a preference order calculator setting a preference order to the plural batteries at each time point based on a deterioration characteristic of each battery related to each SOC thereof, and a distribution rate determining unit distributing the charge/discharge power value to the PCSs in accordance with the preference order."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Secondary battery system with plural batteries and method of distributing charge/discharge power","description":"A secondary battery system including plural batteries, extends the lifetime of each battery, and improves the charge/discharge (energy) efficiency of a whole system is provided.
