BATTERY SYSTEM AND ITS CONTROL METHOD
First Claim
1. A battery system that is operable in association with an electrical grid, the battery system comprising:
- a battery that charges or discharges electric power;
a control section that controls said battery to charge electric power supplied from said electrical grid and to discharge electric power to said electrical grid; and
a system controller that controls said control section such that said battery system operates in a first mode where electric power that is generated by a pre-designated distributed electric power source associated with said electrical grid is supplied preferentially to a user'"'"'s load or in a second mode where electric power that is charged in said battery is supplied preferentially to said user'"'"'s load.

Abstract
A battery system includes a battery, a control section that controls the battery to charge electric power supplied from the electrical grid and to discharge electric power to the electrical grid; and a system controller. The system controller controls the control section such that the battery system operates in a first mode where electric power that is generated by a pre-designated distributed electric power source associated with the electrical grid is supplied preferentially to a user'"'"'s load or in a second mode where electric power that is charged in the battery is supplied preferentially to the user'"'"'s load.

5. A control method for a battery system that is operable in association with an electrical grid, the battery system including:
-
a battery that charges or discharges electric power; and a control section that controls said battery to charge electric power supplied from said electrical grid and to discharge electric power to said electrical grid, the control method comprising; causing a computer to control said control section such that said battery system operates in a first mode where electric power that is generated by a pre-designated distributed electric power source associated with said electrical grid is supplied preferentially to a user'"'"'s load or in a second mode where electric power that is charged in said battery is supplied preferentially to said user'"'"'s load. - View Dependent Claims (6, 7, 8)
