Abstract
Provided is a power supply control device including a command sending unit configured to deliver a polling command to a bus line, and a battery registration unit configured to give an identifier to a battery device that has responded to the polling command within a predetermined response period. The command sending unit delivers information of the identifier to the bus line for the battery device to which the battery registration unit gives the identifier and delivers, to the bus line, a command for the battery device to which the identifier is given.
Claims12
A power supply control device comprising:
- a command sending unit configured to deliver a polling command to a bus line;
- and
- a battery registration unit configured to give an identifier to a battery device that has responded to the polling command within a predetermined response period,
- wherein the command sending unit delivers information of the identifier to the bus line for the battery device to which the battery registration unit gives the identifier and delivers, to the bus line, a command for the battery device to which the identifier is given.
A battery device comprising:
- a command response unit configured to receive a polling command delivered to a bus line and to respond within a predetermined response period;
- an identifier obtaining unit configured to obtain an identifier given based on a response from the command response unit;
- and
- a charge and discharge control unit configured to control charge and discharge by receiving the command which is delivered to the bus line and the identifier of which is specified.
A power supply system comprising:
- a power supply control device;
- and
- one or more battery devices,
- wherein the power supply control device includes
- a command sending unit configured to deliver a polling command to a bus line, and
- a battery registration unit configured to give an identifier to the battery device that has responded to the polling command within a predetermined response period,
- wherein the command sending unit delivers information of the identifier to the bus line for the battery device to which the battery registration unit gives the identifier and delivers, to the bus line, a command for the battery device to which the identifier is given, and
- wherein the battery device includes
- a command response unit configured to receive the polling command delivered from the power supply control device to the bus line and respond within a predetermined response period,
- an identifier obtaining unit configured to obtain the identifier given by the power supply control device based on a response from the command response unit, and
- a charge and discharge control unit configured to control charge and discharge by receiving the command which is delivered from the power supply control device to the bus line and the identifier of which is specified.
A power supply control method comprising:
- delivering a polling command to a bus line;
- giving an identifier to a battery device that has responded to the polling command within a predetermined response period;
- delivering information of the identifier to the bus line for the battery device to which the identifier is given;
- and
- delivering, to the bus line, a command for the battery device to which the identifier is given.
