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.
Claims8
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.
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.
