As disclosed in Patent Documents 1 and 2, a system has been proposed and realized in which a user or a person in charge of maintenance remotely obtains a state of a storage element itself or a device using the storage element. However, until now, a system capable of collectively presenting various kinds of information on the storage element and the power supply-related device has not been realized.

Storage devices such as lead storage batteries or lithium-ion batteries are increasingly applied to industrial applications other than in-vehicle applications (automobile applications, motorcycle applications). For example, a storage element may be installed in parallel in a solar power generation system. In this case, the power storage element is connected to the power conditioner. In a large-scale solar power generation system called a mega solar, a large number of power storage elements and power conditioners are installed and used. Even when realizing the electric power peak cut in a factory or a large-scale facility, a large number of power storage elements and power conditioners are installed and used. Even in railway applications, a large number of power storage elements and a rectifier that is a DC or AC power supply device are installed and used. The conventional maintenance support system does not assume a case where such a large number of power storage devices and power supply-related devices are installed in a distributed power supply system or a business entity.

Along with the permeation of IoT (Internet of Things) into society, expectations for the realization of remote monitoring of power storage devices and power supply-related devices and the realization of value-added services thereby are increasing.

For maintenance management of a system including power storage elements and power supply related devices, the conventional maintenance support system independently developed for each power storage device itself or power supply related device included in the system can be used, but the usage is also displayed. There is no sense of unity in the aspect, and maintenance management becomes complicated.

An object of the present invention is to provide a communication device that can be mounted on either a power storage element or a power supply related device, but presents information according to the type of the device.

The communication device includes a storage unit that stores a device program. The device program stored in the storage unit includes an OS (Operating System) program, a Web server program operating on the OS, and a communication program as a common part, and the device program is a storage device to which the communication device is connected. Web screen data corresponding to each module or power supply related device is included as an individual part.

With the above configuration, the communication device can be mounted on either the power storage module or the power supply related device, and also stores a device program including a common program and operates based on the device program. In addition to the common program, the device program includes Web screen data for displaying a screen in a different manner depending on whether the target is a communication module or another power-related device. Even a system including a wide variety of devices can be equipped with a communication device that is the same hardware and can communicate using the same Web function.

In addition to the common part described above, the device program of each communication device stores, as an individual part, screen data that differs from each communication device depending on the power storage module or the power supply related apparatus. This makes it possible to display different screens depending on the power storage module or the power supply related device, and it becomes easy to visually identify whether the screen is information on the power storage module or information on the power supply related device.

The power supply-related device may be an inverter or converter that performs AC-DC conversion or frequency conversion of the current obtained from the power storage element, an uninterruptible power supply device that uses the inverter or converter, or a rectifier.

External communication programs that realize different protocols (message formats) or functions depending on the type of connected device may be individually stored in each communication device. Many programs stored in the communication device are common, including the Web server program. However, as an individual program, if the device is an uninterruptible power supply, a program is stored that allows it to accept shutdown control from the outside, and if it is another device, it follows the abnormal communication protocol for each device. A program for communication is stored.

The communication device includes: a first communication unit that communicates with the power storage module or a power supply-related device; a second communication unit that communicates with the first device or a second device; and a second communication unit that transmits from the first device. When a request is received, the information processing apparatus may further include a first transmission unit that transmits information including a state of the power storage module or the power supply related device obtained from the first communication unit to the first device from the second communication unit. ..

With the above configuration, the specific first device collects information including the states of the power storage module and the power supply related device from each communication device. Since it is possible to present the collected states of each power storage module and the power-related device, it is possible for the user or the person in charge of maintenance to obtain collective information for each system or each location.

When the communication device receives a transmission request from the second device in the second communication unit, the communication device acquires a state including a state of the power storage module or the power supply related device from the first communication unit, and acquires the obtained information. A second transmission unit that creates display information to be displayed based on the Web screen data and sends the created display information to the second device from the second communication unit may be provided.

With the above configuration, it is possible to acquire the status information of each of the power storage module and the power supply related apparatus from the communication device.
