DETAILED DESCRIPTION OF THE INVENTION

[0009] A battery monitoring system according to one embodiment of the present invention will be described in detail below with reference to the drawings.

[0010] Fig. 1 is an explanatory diagram showing an overview of the storage battery monitoring system 1. Fig. 2 is a block diagram of the electrical equipment 3. Fig. 3 is an explanatory diagram showing a management screen for the storage batteries 10, 10, etc. Fig. 4 is an explanatory diagram showing a voltage transition chart of the storage battery 10. The storage battery monitoring system 1 comprises electrical devices 3, 3, ... each equipped with a storage battery 10, a cloud server device 4, and a terminal computer 5 carried by a user. The electrical device 3 is, for example, a temporary traffic light or an electronic sign, and comprises a storage battery 10 that supplies power to a load 6 of the electrical device 3, and a solar panel 11 for charging the storage battery 10. The electrical device 3 also comprises a GPS unit 12 for acquiring location information of the storage battery 10 using GPS, a voltage measurement unit 13 for measuring the voltage of the storage battery 10, and a communication unit 14 for transmitting the acquired location information and measured voltage to the cloud server device 4.

[0011] Meanwhile, the cloud server device 4 is installed in a data center or the like, receives the location information and measured voltage values ​​transmitted from the communication unit 14, and determines the state of the storage battery 10 as described below based on the location information and measured voltage values, and transmits various information including the results of the state determination to the terminal computer 5 via the Internet 2. The terminal computer 5 is a well-known computer used by a user in an office or the like, and is equipped with a display unit, input unit, control unit, etc., as well as an email function. The location information and measured voltage values ​​are transmitted from the communication unit 14 of the storage battery 10 to the cloud server device 4 via LTE communication.

[0012] Here, notification of the remaining capacity of the storage battery 10 in the storage battery monitoring system 1 will be described. First, when using the storage battery monitoring system 1, the user accesses the cloud server device 4 using the terminal computer 5 and sets identification information (for example, a name) and an initial location for each electrical device 3 (i.e., storage battery 10). The user also sets the type and remaining charge thresholds (first and second thresholds, described below) for each storage battery 10. The user also sets an email address for the terminal computer 5. Note that the cloud server device 4 has stored in advance characteristics relating to the relationship between voltage and remaining charge of each storage battery, each corresponding to a different type of storage battery.

[0013] In each electrical device 3 installed at the initial position set by the user, voltage measurement unit 13 measures the voltage of storage battery 10 at predetermined voltage measurement intervals (e.g., every two minutes) and stores the measured value in its own memory. GPS unit 12 acquires its own location information using GPS at predetermined location measurement intervals (e.g., every 10 minutes) and stores the location information in its own memory. Communication unit 14 then transmits the location information stored in GPS unit 12 and the voltage measurement value stored in voltage measurement unit 13 to cloud server device 4 at predetermined communication intervals (e.g., every 10 minutes).

[0014] Meanwhile, the cloud server device 4 determines, based on the received location information, whether the location of the storage battery 10 has moved a predetermined notification distance (e.g., 100 m) or more from an initial location preset by the user. If it determines that the storage battery 10 has moved a distance greater than the notification distance, it determines that the storage battery 10 may have been stolen or unintentionally moved due to a disaster or the like, and notifies the terminal computer 5 of this by email. Furthermore, based on the received voltage measurement value, it calculates the remaining charge of the storage battery 10 at the time of reception and determines whether the remaining charge of the storage battery 10 has fallen below a first threshold preset by the user. If it determines that the remaining charge of the storage battery 10 has fallen below the first threshold, it determines that the electrical appliance 3 may stop operating, and notifies the terminal computer 5 of this by email. Furthermore, if the cloud server device 4 is unable to receive new location information and voltage measurement values ​​from the communication unit 14 even though communication time has passed since the last time it received data from the communication unit 14, it will notify the terminal computer 5 by email that there is a possibility that the communication unit 14 is malfunctioning.

[0015] Next, a display mode on the display unit of the terminal computer 5 when the cloud server device 4 is accessed from the terminal computer 5 will be described. 3, the management screen for the storage batteries 10, 10, etc., displays a list of identification information 21 of the storage battery 10 (electrical device 3), remaining charge 22 of the storage battery 10, and location information 23 of the storage battery 10. Each storage battery 10 is provided with an input display unit 24 for inputting a first threshold value for calling attention to the remaining charge of the storage battery 10, an input display unit 25 for inputting a second threshold value for notifying a limit of the remaining charge of the storage battery 10, and a remaining charge identification display unit 26 for displaying an identification display relating to the remaining charge of the storage battery 10. When the remaining charge of the storage battery 10 calculated based on the measured voltage value received from the storage battery 10 is equal to or greater than the first threshold value, the remaining charge identification display unit 26 displays a first identification display (specifically, a green circle) as an identification display. Furthermore, when the remaining charge of the storage battery 10 is less than the first threshold and is equal to or greater than the second threshold, a second identification mark (specifically, a yellow circle) is displayed as an identification mark on the remaining charge identification display unit 26. Furthermore, when the remaining charge of the storage battery 10 is less than the second threshold, a third identification mark (specifically, a red circle) is displayed as an identification mark on the remaining charge identification display unit 26.

[0016] 4 can be displayed for each storage battery 10. In the voltage transition chart, voltage measurement values ​​31 received from the storage battery 10 are displayed in chronological order along with date and time 32. The cloud server device 4 also acquires weather information from a weather information site (for example, the Japan Meteorological Agency site), and displays weather icons 33 based on the weather information in correspondence with the date and time 32.

[0017] According to the storage battery monitoring system 1 having the above configuration, each storage battery 10 is provided with a voltage measurement unit 13 and a communication unit 14. When the remaining charge of the storage battery 10 calculated by the cloud server device 4 based on the voltage measurement value received from the storage battery 10 is less than a first threshold and equal to or greater than a second threshold, a second identification mark is displayed on the remaining charge identification display unit 26 as an identification mark. When the remaining charge of the storage battery 10 is less than the second threshold, a third identification mark is displayed on the remaining charge identification display unit 26 as an identification mark. Furthermore, when the remaining charge of the storage battery 10 is less than the first threshold, there is a risk that the electrical device 3 may stop operating, and a notification to that effect is sent to the terminal computer 5 by email. Therefore, the remaining charges of the storage batteries 10, 10... can be monitored without having to go to the installation locations of the storage batteries 10, 10..., making the storage battery monitoring system 1 very user-friendly.

[0018] Furthermore, a GPS unit 12 is provided for each storage battery 10, and location information along with voltage measurements is transmitted to the cloud server device 4 via a communication unit 14. The cloud server device 4 also displays location information 23, 23... of the storage batteries 10, and if the storage battery 10 has moved beyond a notifiable distance, it notifies the terminal computer 5 by email that there is a risk that the storage battery 10 has been stolen or has been unintentionally moved due to a disaster or the like. Therefore, the current locations of the storage batteries 10, 10... can be ascertained without the need to go to the installation locations of the storage batteries 10, 10..., and even if the storage batteries 10, 10... have been stolen or have been unintentionally moved due to a disaster or the like, it is possible to know that this situation has occurred.

[0019] Furthermore, when accessed from the terminal computer 5 by the cloud server device 4, the display unit of the terminal computer 5 displays the received voltage measurement values ​​31 for each storage battery 10 in chronological order along with the date and time 32, and also displays a weather icon 33 based on the weather information obtained from the weather information site in correspondence with the date and time 32. Therefore, it is possible to monitor the remaining capacity of the storage batteries 10, 10... without having to go to the installation locations of the storage batteries 10, 10..., and by being able to know the weather at the installation locations of the storage batteries 10, 10..., it is possible to predict the future operating status of the storage batteries 10, 10..., making the storage battery monitoring system 1 extremely easy to use.

[0020] The battery monitoring system of the present invention is not limited to the above-described embodiments, and the configurations of the battery, cloud server device, and terminal device can be modified as needed within the scope of the present invention.

[0021] For example, in the above embodiment, a terminal computer is used as the terminal device, but it is of course also possible to use other terminal devices such as a smartphone or a tablet device. Furthermore, with regard to the display on the display unit of the terminal device when the terminal device accesses the cloud server device, it is also possible to configure the cloud server device to acquire map information from a map site and display the location of the storage battery on the map based on the received location information. When displaying the location of the storage battery on the map, it is of course also possible to display an identification indication according to the remaining charge of the storage battery or to display the remaining charge of the storage battery as a numerical value.

[0022] Furthermore, in the above embodiment, the cloud server device is configured to calculate the remaining charge of the storage battery based on the received voltage measurement value, and to display an identification display or send an email notification depending on the remaining charge of the storage battery, but this configuration is synonymous with a configuration that uses the voltage measurement value as is (such as comparing the voltage measurement value with a threshold value), and it is also possible to configure the device not to calculate the remaining charge of the storage battery. In addition, it goes without saying that the time and distance set as the voltage measurement time, position measurement time, communication time, and notification distance can be changed as appropriate.
