[0036] Fig. 5 is a sequence diagram of an operation example 1 of the electric device system shown in Fig. 1. When a user starts a management application, the management application connects to the electric device 1A of company A for communication, and the electric device 1A of company A transmits device information to the management application indicating that the electric device 1A is an impact driver of company A (brand A). The management application displays a screen related to the auto-stop setting, for example, as shown in Fig. 12(A), that is, displays the impact time as a parameter of the auto-stop setting.

[0037] After that, the user instructs the management app to switch the connection destination from company A's electric device 1A to company B's electric device 1B. The management app requests company A's electric device 1A to disconnect communication, and company A's electric device 1A disconnects communication with the management app. The management app then connects to company B's electric device 1B, and company B's electric device 1B transmits device information to the management app indicating that it is an impact driver of company B (brand B). The management app displays a screen related to the auto-stop setting, for example, as shown in Fig. 12(B), i.e., displays the tightening torque as a parameter of the auto-stop setting.

[0038] According to the sequence of FIG. 5, the electric device 1A of company A and the electric device 1B of company B can be customized with a common management application, which is easy to use and reduces the development cost of the management application. On the other hand, since the screen display for customization is switched for each manufacturer, the characteristics of each manufacturer can be expressed, which is highly convenient. In addition, even if the parameter of the auto-stop setting is the fastening torque, the impact time corresponding to the set fastening torque can be transmitted. Therefore, whether the impact time or the fastening torque is displayed as a parameter of the auto-stop setting, the communication content between the management application and the electric device 1A of company A and the electric device 1B of company B may be the same. In other words, since the difference in brands can be handled simply by changing the screen display on the management application side according to the brand transmitted as the device information, the communication content itself does not need to be changed according to the brand of the electric device, and the development cost of the management application is reduced compared to the case where the communication content is changed for each brand.

[0039] Fig. 6 is a sequence diagram of an operation example 2 of the electric equipment system shown in Fig. 1. When a user installs and starts a management application on a mobile terminal 80, the management application displays a consent confirmation to a license agreement, license information, and privacy policy (hereinafter "license agreement, etc.") on the premise that the application will be connected only to electric equipment of company A. When the user performs an operation to consent, the management application becomes available on the premise that the application will be connected only to electric equipment of company A.

[0040] When the user instructs the management app to connect to company B's electrical device 1B, company B's electrical device 1B sends device information to the management app indicating that it is an impact driver from company B (brand B). The management app then displays a confirmation of consent to the license agreement, etc., on the premise that the device will connect to company B's electrical devices in addition to company A's electrical devices. When the user performs the consent operation, the management app can be used on the premise that the device will connect to company B's electrical devices in addition to company A's electrical devices.

[0041] According to the sequence of FIG. 6, it is possible to suppress the discomfort felt by a user who owns only the company A's electric device 1A when a confirmation of consent to a license agreement or the like is displayed on the assumption that the device will be connected to the company B's electric device 1B, which the user has no plans to connect.

[0042] Fig. 7 is a sequence diagram of an operation example 3 of the electric equipment system shown in Fig. 1. When a user installs a management app on a mobile terminal 80 and starts it, the management app displays a link to the homepage of company A. When a user instructs the management app to connect to company B's electric equipment 1B, company B's electric equipment 1B transmits device information to the management app indicating that it is an impact driver of company B (brand B). The management app displays a link to company B's homepage in addition to or instead of the link to company A's homepage.

[0043] According to the sequence of Fig. 7, a user who has connected to Company B's electric device 1B can easily browse Company B's website from the management application screen, which is convenient. Instead of or in addition to the link to the brand's website, a link to access the website of the manufacturer of the electric device, or product information or an instruction manual for the electric device may be displayed. Parameters for setting the operation of the electric device, such as parameters related to auto-stop settings and parameters related to adjusting the trigger pull amount, can also be received from the linked website and applied to the electric device, which further enhances convenience.

[0044] Fig. 8 is a sequence diagram of an operation example 4 of the electrical equipment system shown in Fig. 1. When a user starts a management app in Japan, the management app connects to the electrical equipment for communication. Meanwhile, the management app acquires GPS location information, recognizes that the location is Japan, and displays the Japanese brand. When a user starts a management app in North America, the management app connects to the electrical equipment for communication. Meanwhile, the management app acquires GPS location information, recognizes that the location is North America, and displays the North American brand.

[0045] According to the sequence in Figure 8, if a manufacturer sells electrical equipment under different brands for each country or region, the management application automatically displays the brand according to the country or region, which is easy to use.

[0046] Fig. 9 is a sequence diagram of an operation example 5 of the electric device system shown in Fig. 1. When a user starts the management app, the management app connects to company A's electric device 1A for communication, and company A's electric device 1A transmits device information to the management app indicating that it is an impact driver of company A (brand A). The management app displays the remaining number of times (life) that the battery pack 20 attached to company A's electric device 1A can be charged and discharged as N times. In this specification, "N times" refers to the remaining number of times (life) that the battery pack 20 can be charged and discharged according to company A's standards.

[0047] The user then instructs the management app to switch the connection destination from company A's electrical device 1A to company B's electrical device 1B. The management app requests company A's electrical device 1A to disconnect communication, and company A's electrical device 1A disconnects communication with the management app. The management app then connects to company B's electrical device 1B, and company B's electrical device 1B transmits device information to the management app indicating that it is an impact driver of company B (brand B). The management app displays the remaining number of times (lifespan) that the battery pack 20 attached to company B's electrical device 1B can be charged and discharged as N-150 times.

[0048] 9, the remaining number of times of charging and discharging (lifespan) can be changed according to the characteristics of the users targeted by each of companies A and B, which is convenient. For example, if the users targeted by company B require a higher accuracy of fastening torque than the users targeted by company A, the remaining number of times of charging and discharging (lifespan) can be displayed more strictly (or less) for the battery pack 20 attached to company B's electric device 1B, which can prompt the user to replace the battery pack 20 with a new one early before the torque error becomes large, which is convenient.

[0049] Fig. 10 is a sequence diagram of an operation example 6 of the electric device system shown in Fig. 1. When a user starts the management app, the management app connects to the electric device 1A of company A for communication, and the electric device 1A of company A transmits device information to the management app indicating that the electric device 1A is an impact driver of company A (brand A). The management app displays the discharge cutoff voltage of the battery pack 20 attached to the electric device 1A of company A as V volts.

[0050] The user then instructs the management app to switch the connection destination from company A's electric device 1A to company B's electric device 1B. The management app requests company A's electric device 1A to disconnect communication, and company A's electric device 1A disconnects communication with the management app. The management app then connects to company B's electric device 1B, and company B's electric device 1B transmits device information to the management app indicating that it is an impact driver of company B (brand B). The management app displays the discharge stop voltage of battery pack 20 attached to company B's electric device 1B as V+0.5 volts.

[0051] According to the sequence of Fig. 10, Company A and Company B can change the discharge stop voltage according to the characteristics of their respective target users, which is convenient. For example, if Company B's target users require a higher precision fastening torque than Company A's target users, the discharge stop voltage can be displayed more strictly (higher) for the battery pack 20 attached to Company B's electric device 1B, encouraging the user to charge the battery pack 20 early before the torque error becomes large, which is convenient.

[0052] FIG. 11 is a table summarizing combinations of items that can be set or checked for electrical equipment using an application installed on the mobile terminal 80, and parameters or notation content corresponding to the items, which differ depending on the manufacturer or brand of the electrical equipment.

[0053] The notation of the auto-stop setting in Figure 11 corresponds to the difference in display as shown in the sequence in Figure 5 and Figures 12(A) and (B), and in the case of Company A (Brand A), it is expressed by impact time, and in the case of Company B (Brand B), it is expressed by tightening torque.

[0054] The kickback setting in Figure 11 is, for example, an indication of the operating condition of a function that stops the motor when kickback occurs when the electrical equipment is a hammer drill or the like, and is indicated by the motor rotation speed in the case of Company A (or Brand A), and by the pressing load in the case of Company B (Brand B).

[0055] The notation of the rotation speed setting (drilling speed setting) in Figure 11 corresponds to, for example, the case where the electrical equipment is a drill or other drilling tool, and in the case of Company A (or Brand A), it is expressed in terms of the rotation speed of the motor or the tip tool, in the case of Company B (Brand B), it is expressed in terms of the drilling speed (drilling depth per unit time), and in the case of Company C (Brand C), it is expressed in terms of the noise level.

[0066] This embodiment provides the following advantages.

[0067] (1) The management application can wirelessly connect to multiple electrical devices of different brands or manufacturers, and displays information about the wirelessly connected electrical devices on the screen (display unit 83) of the mobile terminal 80 that differs depending on the brand or manufacturer of the electrical device (for example, Figs. 12(A) and (B) or Figs. 13(A) and (B)). This makes it possible to manage multiple electrical devices of different brands or manufacturers with a common management application, which is easy to use and reduces the development costs of the management application.

[0068] (2) The management app can wirelessly connect to a plurality of electrical devices owned by different users (owners), and displays information about the wirelessly connected electrical devices on the screen (display unit 83) of the mobile terminal 80 in a manner that differs depending on the user of the electrical device (e.g., FIGS. 14(A) and 14(B)). This allows the display about the electrical device to be changed according to the characteristics of the user (whether or not high precision is required for the tightening torque, etc.) using a common management app, which is easy to use and reduces the development costs of the management app.

[0069] (3) The management application receives device information (information about the brand or manufacturer) from the wirelessly connected electric device, and performs different display on the screen (display unit 83) of the mobile terminal 80 depending on the brand or manufacturer of the electric device based on the received device information (for example, Figs. 12(A), (B) and 13(A), (B)). In addition, the management application performs different display on the screen (display unit 83) of the mobile terminal 80 depending on the brand, manufacturer or owner of the electric device based on the common content of wireless communication between multiple electric devices having the same function but different brands, manufacturers or owners (for example, electric device 1A of company A and electric device 1B of company B). Therefore, there is no need to transmit information instructing the display mode from the electric device to the management application, and the communication content can be common. Therefore, even if the electric devices are made by different manufacturers or brands, the communication program with the management application can be common, and the development cost of the communication program and the management application can be reduced.
