Title:
HOME DISCHARGE CONTROL DEVICE AND HOME DISCHARGE CONTROL METHOD
Document Type and Number:
Japanese Patent JP2013046557
Kind Code:
A
Abstract:

To provide a home discharge control device which accurately detects the remaining capacity of an external battery with a current sensor for large current when storage power of the external battery is used for a home load.

A home discharge control device includes: a voltage sensor 9 detecting output voltage of an external battery 20; a power sensor 11 detecting load power of a home load 30; a control part 21 calculating a calculation value of a first discharge current of the external battery 20 from the detection results of the voltage sensor 9 and the power sensor 11; and a DC/DC converter 15 controlling the discharging of the first discharge current from the external battery 20 for supplying the electric power to the home load 30. The DC/DC converter 15 causes the first discharge current to be discharged to the home load 30 when the calculation value is equal to or higher than a first predetermined value.
