  "textContent": "A circulating current flowing between a first electric storage apparatus and a second electric storage apparatus may deteriorate a first relay and a second relay. [SOLVING MEANS] An electric storage system includes a first electric storage apparatus and a second electric storage apparatus each performing charge and discharge, a first relay and a second relay, and a controller. The first relay enables the charge and discharge of the first electric storage apparatus in an ON state and disables them in an OFF state. The second relay enables the charge and discharge of the second electric storage apparatus in an ON state and disables them in an OFF state. The first electric storage apparatus and the first relay are connected in parallel to the second electric storage apparatus and the second relay. The controller switches each of the first relay and the second relay from the ON state to the OFF state after the controller allows a circulating current flowing between the first electric storage apparatus and the second electric storage apparatus.",
