1. A battery system comprising:
- a plurality of battery groups that respectively include at least one battery module including at least one battery cell, and have predetermined target using periods;
a connector for selectively connecting the plurality of battery groups to an external object; and
a controller that calculates a margin at the end of the target using period of each battery group based on a deterioration amount of each battery group, and controls the connector based on the calculated margin.

Abstract
A battery module group includes a plurality of battery groups. Each battery group includes a plurality of battery modules. Cell information is supplied from each battery module of the battery module group to a charge/discharge controller. The charge/discharge controller controls the turning on and off of a plurality of switching elements of a connector based on the supplied cell information of each battery module. The plurality of switching elements correspond to the plurality of battery groups, respectively. Thus, the plurality of battery groups are selectively connected to an external object via a DC/AC converter.
