[0002] The battery swap cabinet is mainly designed to solve the problem of frequent battery swapping for riders, couriers, and other people who have short battery life and high safety risks for charging indoors or in buildings. Existing battery swap cabinets generally integrate intelligent battery swapping methods and systems to control the battery compartment.

[0003] The current common battery replacement methods are generally: the main control board, warehouse control board, and battery are connected through a wired communication mode, such as a conventional LAN communication mode; the battery information must first be collected by the warehouse control board and then reach the main control board; the main control board uses 4G communication to exchange information with the server.

[0004] Chinese patent CN113232548A discloses an offline battery replacement method, system, terminal and storage medium of a battery swap cabinet. When it detects that it is in an offline state, it receives a Bluetooth connection request initiated by a user terminal; when receiving an order sent by the user terminal through a Bluetooth connection, it opens an idle battery compartment and prompts to put in the battery to be replaced; obtains the first ID of the battery to be replaced placed in the idle battery compartment, and determines whether the first ID is consistent with the second ID in the order; if so, opens the fully charged battery compartment and prompts to take out the fully charged battery in the fully charged battery compartment. It discloses enabling Bluetooth connection in an offline state, establishing a Bluetooth connection with the user terminal to transmit data when the battery swap cabinet itself is offline or the network is unstable, opening an idle battery compartment and prompting to put in the battery to be replaced when receiving an order sent by the user terminal through a Bluetooth connection; and verifies the legitimacy of the user's battery to ensure the smooth completion of the battery replacement task. This patent only solves the technical solution of how users verify battery replacement when the battery swap cabinet network is offline.

[0005] In the current commonly used power exchange cabinet composition, there are several problems that cannot be solved:

[0006] 1. When the battery is frequently replaced, the battery may be placed in the battery compartment without the data cable properly plugged in, causing the battery to drop out of service;

[0007] 2. The battery is in the battery swap cabinet. Due to external vibration, the data line is in poor contact, causing the battery to drop out, or the charging port is in poor contact, causing the battery to be not fully charged;

[0008] 3. The warehouse control board and the battery are only connected by wire. If the wired communication is abnormal after long-term use, the battery cannot be replaced for the user. Summary of the invention

[0009] The purpose of the present invention is to avoid the shortcomings of the prior art and provide a battery replacement cabinet that can restore offline batteries.

[0042] Step S2: When the main control board cannot obtain the battery information of the battery compartment, it is determined that the battery in the battery compartment is offline or faulty, and the main control board connects to the battery module of the battery compartment in Bluetooth mode;

[0043] If the main control board cannot connect to the battery module via Bluetooth, it is determined that the battery module in the battery compartment is faulty, and the battery compartment is disabled;

[0044] If the main control board and the battery module can be connected via Bluetooth, it is determined that the battery module in the battery compartment is offline;

[0045] Step S3: The main control board sends the Bluetooth name and Bluetooth MAC address corresponding to the battery module to the server for authentication through the regular communication module of the main control board;

If the legal battery is replaced with a offline battery, the compartment control board corresponding to the offline battery module and the main control board are restored to wired communication mode for management and control.

[0053] 2. For this battery swap cabinet, the battery that goes offline due to non-fault reasons does not require maintenance personnel to intervene. The main control board can also obtain the battery information of the battery module through the Bluetooth mode, and after the user replaces the battery, it can automatically restore to the wired communication mode to manage the battery module of the warehouse control board.

[0054] 3. For this battery swap cabinet, when the status of the in-place detection switch is that the battery is in place, the status of the charging module is that there is a battery load, and the main control board cannot obtain the battery information in the wired communication mode, it is judged that the battery module in the battery compartment is offline or faulty.

[0055] 4. For this battery swap cabinet, the disconnected battery taken out by the user may not be fully charged. The user can request to re-swap the battery as needed. The re-swapped disconnected battery will restore the wired communication mode connection and continue charging to solve the technical problem of poor contact of the charging interface of the disconnected battery.

If the travel switch is closed, it indicates that the battery is in place. After the battery module is taken out of the battery compartment, the travel switch will automatically pop up and the travel switch will be disconnected, indicating that the battery is not in place.

[0083] When the status of the in-place detection switch is that the battery is in place, the status of the charging module is that there is a battery load, and the main control board cannot obtain battery information in the wired communication mode, it is determined that the battery module in the battery compartment is offline or faulty.

[0084] For this battery swap cabinet, when the status of the in-place detection switch is that the battery is in place, the status of the charging module is that there is a battery load, and the main control board cannot obtain the battery information in the wired communication mode, it is judged that the battery module in the battery compartment is offline or faulty.

[0085] Embodiment 3: The other technical features of this embodiment are the same as those of Embodiment 2, except that:

[0093] The clock power module is used to record the power replacement time and provide power to the main control board.

[0094] Embodiment 5: The other technical features of this embodiment are the same as those of Embodiment 1, except that:

[0095] like Figure 3As shown, the warehouse control board also includes a CAN address dial module, a CAN bus module, a charging module interface, a battery BMS communication interface, a relay door lock control module, and a clock power supply module;

[0096] The CAN address dial module is used to: distinguish the address identification of each battery compartment in the same network;

[0100] The relay door lock control module controls the electric lock to open the door by closing the relay;

[0101] The bin control board is connected to the battery in-place detection switch in the battery bin;

[0102] The clock power module is used to record the warehouse opening time and provide power to the warehouse control board.

[0103] Embodiment 6: The other technical features of this embodiment are the same as those of Embodiment 1, except that:

[0105] The charging port is used to connect the charging module to charge the battery;

[0106] The RS485 interface is used to connect to the warehouse control board so that the warehouse control board can obtain battery information;

[0107] The battery Bluetooth is used to communicate with the main control board via Bluetooth.

[0110] like Figure 1As shown, the main control Bluetooth is GATT CLIENT Bluetooth, the battery Bluetooth is GATT SERVER Bluetooth, and the main control board and the battery module communicate in GATT CLIENT / SERVER mode. Because the battery module has its own GATT SERVER Bluetooth, the main control board can directly access the battery module through the GATT CLIENT main control Bluetooth on the board, and then directly obtain the data of the battery module. GATT CLIENT / SERVER is a one-to-many Bluetooth connection.

[0111] Embodiment 8: The other technical features of this embodiment are the same as those of Embodiment 1, except that: Figure 1-4 As shown, the conventional communication module includes at least one of the 2G / 3G / 4G / 5G communication modules.

[0112] Embodiment 9: The other technical features of this embodiment are the same as those of Embodiment 1, except that: Figure 1-4 As shown, the wired communication mode is a CAN bus LAN composed of CAN bus modules between the main control board and the warehouse control board. After the main control board and one or more warehouse control boards are powered on and initialized, the CAN bus modules on each control board will automatically form a CAN bus LAN. The main control board can control the warehouse control board through the CAN bus LAN, and then control the charging module to charge the battery through the warehouse control board. At the same time, the main control board can also collect data from the warehouse control board through the CAN bus, and then the warehouse control board obtains the data of the battery module through RS485 and transmits it to the main control board.

[0113] In this battery exchange cabinet, each warehouse control board is equipped with a CAN address dial module and a CAN bus module. Each warehouse control board and the main control board use their own CAN bus modules to form a wired communication mode - CAN bus local area network. After the main control board receives the battery exchange command, the warehouse control board executes the command of the main control board through the CAN local area network to control the relay door lock control module, control the opening and closing of the battery compartment, execute battery charging and replacement services, and return the user's battery exchange information to the server through the main control board.

[0114] Embodiment 10: The other technical features of this embodiment are the same as those of Embodiments 1-9, except that:

[0115] The power exchange cabinet performs power exchange through the following steps:

[0116] Step S1: The main control board that interacts with the server data communicates with the battery compartment control board in a wired communication mode to obtain battery information in the battery compartment;

[0117] Step S2: When the main control board cannot obtain the battery information of the battery compartment, it is determined that the battery in the battery compartment is offline or faulty, and the main control board connects to the battery module of the battery compartment in Bluetooth mode;

[0118] If the main control board cannot connect to the battery module via Bluetooth, it is determined that the battery module in the battery compartment is faulty, and the battery compartment is disabled;

[0119] If the main control board and the battery module can be connected via Bluetooth, it is determined that the battery module in the battery compartment is offline;

[0120] Step S3: The main control board sends the Bluetooth name and Bluetooth MAC address corresponding to the battery module to the server for authentication through the regular communication module of the main control board;

[0121] If the authentication fails, the battery module is considered illegal and cannot be charged or replaced, and the battery compartment is disabled;

[0122] If the authentication is passed, the battery module is considered legal and charging and battery replacement services are allowed;

[0123] Step S4: The user requests a battery replacement, and the main control board controls the battery compartment to open an empty battery compartment for the user to put the battery module in, and the main control board sends the battery serial number of the battery module to the server for authentication;

[0124] If the authentication fails, the main control board will open the compartment door to allow the user to retrieve the battery module, ending the battery replacement service;

[0125] After the authentication is passed, if the user takes out a battery module that has been disconnected, the main control board automatically disconnects the Bluetooth connection mode with the battery module that has been disconnected. At the same time, the main control board and the battery compartment control board automatically return to the wired communication mode for management and control.

[0126] Embodiment 11: The other technical features of this embodiment are the same as those of Embodiments 1-9, except that the power exchange cabinet can also perform power exchange through the following steps:

[0127] Step 1, control system initialization: the main control board sets the CAN address dial code, initializes, starts the regular communication module, joins the CAN network, and starts Bluetooth; several warehouse control boards bidirectionally connected to the main control board set the CAN address dial code, initialize, and join the CAN network; the battery module is initialized and Bluetooth is started.

[0128] Step 2: The main control board detects the status of the battery in-place switches in all battery compartments in real time, and detects the load conditions of the charging modules corresponding to all battery compartments;

[0129] Step 3: The main control board determines whether the battery module in the battery compartment can be charged or replaced;

[0130] Step 3-1: If the status of the battery in-place switch in the battery compartment is that the battery is in place and the corresponding charging module detects that there is a battery load, the main control board can normally obtain battery information from the compartment control board and can charge or replace the corresponding battery module;

[0131] Step 3-2, if the status of the battery in-place switch in the battery compartment is that the battery is in place and the corresponding charging module detects that there is a battery load, but the main control board cannot obtain battery information from the compartment control board in wired communication mode, the main control board uses Bluetooth communication mode to directly connect to the battery Bluetooth of the corresponding battery module;

[0132] Step 3-2-1, if the Bluetooth connection authentication fails, it is determined that the battery module in the battery compartment is faulty or an illegal battery, and the main control board disables the battery compartment;

[0133] Step 3-2-2, if the Bluetooth connection authentication is successful, it is determined that the battery module in the battery compartment is offline, and the main control board sends the Bluetooth name and Bluetooth MAC address of the battery module to the server for authentication. Only the battery Bluetooth registered on the server can pass the authentication;

[0134] If the server fails to authenticate the Bluetooth of the offline battery, the battery module in the battery compartment is judged to be an illegal battery, and the main control board disables the battery compartment;

[0135] If the server successfully authenticates the offline battery Bluetooth, the main control board obtains battery information from the battery module through the Bluetooth communication mode, and can charge or replace the corresponding battery module;

[0136] Step 4: After the main control board receives the user's battery replacement instruction, it sends the corresponding control command to the corresponding warehouse control board through the CAN local area network to provide the user with battery replacement services;

[0137] Step 5: The warehouse control board first opens an empty battery compartment through the relay door lock control module to allow the user to put in the battery module that needs to be replaced, connects the battery module to the charging port, and closes the battery compartment;

[0138] Step 6: The main control board sends the battery serial number of the inserted battery module to the server for authentication;

[0139] Step 6-1: If the authentication fails, the main control board will open the door of the compartment to allow the user to retrieve the battery module, ending the battery replacement service;

[0140] Step 6-2, authentication passed, if the warehouse control board opens the battery compartment door of a fully charged battery module through the relay door lock control module, after the user takes out the battery module, the warehouse control board returns the battery replacement information of the user in step 5 and step 6-2 to the main control board; or,

[0141] Step 6-3, authentication passed. If the warehouse control board opens the battery compartment door of a disconnected battery module through the relay door lock control module, after the user takes out the disconnected battery, the warehouse control board returns the battery replacement information of the user in steps 5 and 6-3 to the main control board; the main control board actively disconnects the Bluetooth connection with the offline battery module, and the main control board and the warehouse control board automatically restore to wired communication mode. The main control board switches to obtaining battery information from the warehouse control board. If the user puts a battery module into the battery compartment, the battery module in the battery compartment restores to wired communication mode for management and control.

[0142] The disconnected battery taken out by the user may not be fully charged. The user can return to step 1 and replace the battery as needed. The replaced disconnected battery will restore the wired communication mode connection and continue charging to solve the technical problem of poor contact of the charging interface of the disconnected battery. No maintenance personnel intervention is required, and self-repair is completed during the user's battery replacement process.

[0143] Embodiment 12: The other technical features of this embodiment are the same as those of Embodiments 1-9, except that: Figure 7 As shown, the steps for the main control board to connect to the battery Bluetooth using the Bluetooth communication mode are as follows:

[0144] Y1, the battery Bluetooth of the battery module broadcasts a service access point with the battery ID serial number as the Bluetooth name; the main control Bluetooth of the main control board searches for the Bluetooth name corresponding to the ID serial number of the disconnected battery to be connected; if a matching Bluetooth name is found, a Bluetooth connection is requested from the battery Bluetooth of the battery;
