Abstract

Disclosed herein is a charge/discharge controlling apparatus, including: a charging circuit; a discharging circuit; and a control section configured to control starting and stopping of charging into an electricity accumulating section through the charging circuit and starting and stopping of discharging from the electricity accumulating section through the discharging circuit; the charge/discharge controlling apparatus returning a response, in response to a charging starting instruction received when the electricity accumulating section is in a charging state and to a discharging starting instruction received when the electricity accumulating section is in a discharging state, representing that a process corresponding to the received instruction has been executed.

Claims

1. A charge/discharge controlling apparatus, comprising;

a charging circuit;

a discharging circuit; and

a control section configured to control starting and stopping of charging into an electricity accumulating section through the charging circuit and starting and stopping of discharging from the electricity accumulating section through the discharging circuit;

the charge/discharge controlling apparatus returning a response, in response to a charging starting instruction received when the electricity accumulating section is in a charging state and to a discharging starting instruction received when the electricity accumulating section is in a discharging state, representing that, a process corresponding to the received instruction has been executed.

2. The charge/discharge controlling apparatus according to claim 1, wherein, in response to an instruction to start charging when the electricity accumulating section is in a discharging state, charging into the electricity accumulating section is started after the discharging from the electricity accumulating section is stopped, and in response to an instruction to start discharging when the electricity accumulating section is in a charging state, discharging from the electricity accumulating section is started after the charging into the electricity accumulating section is stopped.

3. A charge/discharge controlling system, comprising:

a first apparatus which includes a charging circuit and a discharging circuit; and

a second apparatus to and from which one or more first apparatus can be connected and disconnected and which signals individual instructions for starting and stopping charging into an electricity accumulating section through the charging circuit and for starting and stopping discharging from the electricity accumulating section through the discharging circuit to the first apparatus;

the first apparatus returning, in response to the instruction for starting charging received when the electricity accumulating section is in a charging state or to the instruction for starting discharging received when the electricity accumulating section is in a discharging state, a response representing that a process corresponding to the received instruction has been executed.

4. The charge/discharge controlling system according to claim 3, wherein

the first apparatus changes a charging rate into the electricity accumulating section in response to a variation of an input voltage supplied thereto from the second apparatus, and

the second apparatus adjusts an output voltage thereof so that the output voltage may be within a range determined in advance in response to a variation of an input voltage from an electric power generation section.
