Communication device, information processing system, information processing method, and computer program

An information processing system comprising:

• a communication device connected to an energy storage device or a power supply related apparatus;
• and
• an information processing apparatus that transmits and receives information to and from the communication device, wherein
• the communication device includes:
• an acquisition part that acquires information including a state of the energy storage device or the power supply related apparatus on a basis of a set timing;
• a change acceptance part that accepts a change in the timing and changes the timing;
• and
• a transmission part that transmits, at a timing after the change, the information acquired by the acquisition part to the information processing apparatus, and
• the information processing apparatus includes:
• a determination part that determines whether the timing needs to be changed;
• and
• an instruction part that transmits to the communication device an instruction to change the timing when the determination part determines that the change is necessary.

An information processing method for processing information by a communication device connected to an energy storage device or a power supply related apparatus and an information processing apparatus that transmits and receives information to and from the communication device, wherein

• the communication device transmits, to the information processing apparatus, information including a state of the energy storage device or the power supply related apparatus acquired at a timing based on a setting,
• the information processing apparatus determines whether the timing needs to be changed,
• the information processing apparatus transmits to the communication device an instruction to change the timing when it is determined that the timing needs to be changed, and
• the communication device changes the timing on a basis of the received instruction for the change.

A computer program stored in a non-transitory computer readable medium, for receiving and displaying information of an energy storage device and/or a power supply related apparatus to a computer provided with a display part, the program causing the computer to perform:

• requesting display information for displaying a state of the energy storage device and/or the power supply related apparatus, the display information being provided for each of systems including the energy storage device and/or the power supply related apparatus or for each of places where the energy storage device and/or the power supply related apparatus is installed;
• collectively displaying the display information for each of the systems or for each of the places on a basis of the display information transmitted in response to the request;
• communicatively connecting to a communication device on a basis of information of connection to the communication device connected to the energy storage device or the power supply related apparatus included in the display information;
• and
• displaying a screen that is provided from the communication device and accepts a change in a timing for acquiring information including the state in the energy storage device or the power supply related apparatus.

A capacity estimation system comprising:

• an information processing apparatus that processes information including a state of an energy storage device;
• a management apparatus that acquires voltage and current in the energy storage device;
• and
• a communication device including a first communication part that communicates with the management apparatus and a second communication part that communicates with the information processing apparatus or another apparatus, wherein
• the communication device includes:
• an acceptance part that accepts an estimation instruction for a full-charge capacity of the energy storage device by using the second communication part;
• and
• a transmission processing part that, when the acceptance part accepts the estimation instruction, transmits the voltage and current acquired from the management apparatus by using the first communication part and/or transmits a state of charge estimated on a basis of the voltage and current by using the second communication part, and
• the communication device changes a timing for acquiring the state in the management apparatus when the acceptance part accepts the estimation instruction.

A communication device comprising:

• a first communication part that is connected to an energy storage device and acquires information of voltage and/or current in the energy storage device;
• a second communication part that communicates with another apparatus;
• an acceptance part that accepts an estimation instruction for a full-charge capacity of the energy storage device through communication in the second communication part;
• and
• a processing part that, when the acceptance part accepts the estimation instruction, controls a switching part configured to switch connection or disconnection of a power line for electric connection to the energy storage device so as to start measurement of the voltage and current in the energy storage device,
• wherein a timing for acquiring a state in the energy storage device is changed when the acceptance part accepts the estimation instruction.

A computer program, stored in a non-transitory computer readable medium, for receiving and displaying information of an energy storage device to a computer provided with a display part, the program causing the computer to perform:

• requesting display information displaying a state of the energy storage device;
• displaying the state of the energy storage device on a basis of display information transmitted in response to the request;
• communicatively connecting to a communication device on a basis of information of connection to the communication device connected to the energy storage device included in the display information;
• and
• displaying a screen that is provided from the communication device and accepts execution of estimation of a full-charge capacity of the energy storage device,
• wherein a timing for acquiring the state in the energy storage device is changed when the execution of the estimation is accepted.
