First, in step S410, the presence of a first smartphone corresponding to the first battery is detected through a network.

In one embodiment, step S410 is completed by the controller 116 of the battery storage device 110. Among them, the controller 116 detects the existence of a smartphone on the wireless network through the wireless network connection unit 114, obtains the identification data of the smartphone through the wireless network, performs an authentication based on the identification data, and according to the authentication result, Determine whether the smartphone detected by the wireless network connection unit is a first smartphone corresponding to the first battery, thereby determining whether the wireless network connection unit 114 detects the first smartphone corresponding to the first battery The existence of mobile phones. It is worth noting that in some embodiments, the wireless network connection unit may be a network connection unit with low energy consumption technology, such as Bluetooth Smart technology. There are two modes in Bluetooth Smart technology, such as peripheral mode and central mode. In the central mode, the network connection unit can receive data from the network connection unit of other electronic devices, and has the ability to actively connect to other electronic devices. In the peripheral mode, the network connection unit can broadcast signals such as its own identification data. However, the network connection unit cannot actively connect to other electronic devices in the peripheral mode. In some embodiments, the wireless network connection unit is in a peripheral mode.

In some embodiments, the authentication based on the identification data is performed by a network server and generates the authentication result of the corresponding authentication. The above-mentioned authentication result may be authentication passed or authentication failed. When the authentication result is that the authentication is passed, the controller 116 determines that the smartphone is the first smartphone, and determines that the wireless network connection unit 114 detects the presence of the first smartphone corresponding to the first battery. When the authentication result is that the authentication fails, the controller 116 determines that the smartphone is not the first smartphone, and determines that the wireless network connection unit 114 does not detect the presence of the first smartphone corresponding to the first battery. In some embodiments, the controller 116 may obtain identification data of one of the smartphones when detecting the presence of a smartphone through the wireless network connection unit, and obtain the corresponding battery's battery identification data based on the smartphone's identification data The position is determined by the plurality of indicators of the battery storage device 110.

Specifically, when a smartphone is close to the battery storage device 110 by a predetermined distance, the smartphone can detect the battery storage device 110 through the wireless network 130 and upload an identification data to the network server through the network 150 140 performs an authentication, so the web server 140 can detect the presence of this smartphone through the network 150. The identification data may include the identification data ID of the smartphone and the device identification data BSID of the battery storage device 110.

Then, in step S420, in response to detecting the presence of the first smartphone corresponding to the first battery, a first control signal is sent to the first indicator in the battery storage device 110, causing the first indicator to output an indication Signal to generate a prompt. It is reminded that according to the type of the first indicator, different prompts can be generated, such as sound prompts, light signal prompts, etc., but the present invention is not limited thereto.
