[0129] Embodiment 5

[0130] The embodiment provides an intelligent charging / battery replacing device management subsystem, which mainly comprises the following modules / devices: ① a core control module, ② an information display and interaction device, ③ a switch control device, ④ a communication control device, ⑤ a battery state monitoring device, ⑥ a charging control device, ⑦ an alternating current output device, ⑧ a network communication module, and ⑨ a fee settlement module.

[0131] The communication interface and related sensors of the battery state monitoring device in the battery charging and replacing box monitor the state and data of the battery modules in the box, and then transmit the information to the core control module in real time through the communication control device. The core control module is connected to the Internet by controlling the network communication module, communicates with the cloud server, interacts data, and displays the state information on the information display and interaction module.

[0132] The user logs into the personal platform account on the charging and battery replacing device through the information display and interaction module by manually inputting an account or APP scanning verification, interacts information with the cloud server through the network communication module, and logs into the personal platform account. In the personal account, the user can check the state and data of the electric vehicle, the vehicle-mounted battery box, the modular battery and the like owned by the user, and issues instructions such as charging / battery replacing or alternating current output according to needs.

[0133] When the "core control module" receives the user's "charging" instruction, it controls the switching state of the "switch control device" through the "communication control device", and further controls the charging action of the "charging control device". For example, if the user indicates that charging to 70% is required during the low electricity consumption period, the "core control module" receives the instruction and controls the "switch control device" to open the charging switch of the "charging control device" at the start point of the specified time period. The charging amount fed back by the "battery state monitoring device" is monitored, and when the 70% charging amount is reached, the "switch control device" is controlled to close the charging switch of the "charging control device", the charging is completed, the relevant information is displayed on the "information display & interaction module", and the state data of each battery is uploaded to the cloud server through the "network communication module".

[0134] When the "core control module" receives the user's "battery replacement" instruction, it guides the user to insert the depleted battery and remove the replaced fully charged battery according to the step prompts on the "information display & interaction module", and uploads and updates the relevant data and ownership relationship of the battery to the cloud server through the "network communication module".

[0135] When the "core control module" receives the user's "AC output" instruction, it instructs to open the "AC output device" switch to supply power externally through the "communication control device", monitors the remaining power information fed back by the "battery state monitoring device", displays it in time on the "information display & interaction module", and uploads it to the cloud server through the "network communication module". When the remaining power reaches the critical value of power supply, a warning information is displayed on the "information display & interaction module", and the "AC output device" switch is controlled to be closed with a delay, the external power supply is completed, and the latest state information is uploaded to the cloud server through the "network communication module".

[0136] For fee settlement, the "core control module" completes fee settlement by calling the relevant interface of the "fee settlement module".

[0137] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can make equivalent replacements or changes within the technical scope disclosed in the present application according to the technical solution and inventive concept of the present application, which should be covered within the protection scope of the present application.
