[0034] Figure 1 This is a schematic diagram of the battery swapping cabinet. Figure 2 This is a structural diagram of the battery compartment. Figure 1 and Figure 2 As shown, the battery swapping cabinet includes a cabinet body 1, multiple battery compartments 2, multiple battery compartment fans 4, a cabinet fan 7, a smoke sensor 12, and a control board 11. The cabinet body 1 is used to install and support the various components of the battery swapping cabinet, such as the battery compartments 2.

[0035] Multiple battery compartments 2 are installed inside the cabinet 1. The battery compartments 2 are used to hold batteries for charging, making it convenient for users to replace them. In some embodiments, the multiple battery compartments 2 are arranged in a matrix within the cabinet 1, which can accommodate a sufficient number of battery compartments 2 to provide enough space for users to charge and replace batteries, saving time.

[0036] The battery compartment 2 can have various feasible shapes, such as cuboid, cylindrical, or prismatic. The battery compartment 2 matches the shape of the battery to facilitate battery insertion. For example, if the battery is cuboid, the battery compartment 2 will be correspondingly cuboid. In some embodiments, the battery compartment 2 is equipped with an electrical connector (i.e., a charging interface). When the battery is placed in the battery compartment 2, it can be electrically connected to the connector and charged. The electrical connector is electrically connected to the control board 11, which can control the connector to connect to power and charge the battery, or stop charging the battery according to instructions (e.g., to prevent overcharging after the battery is fully charged). Furthermore, in some embodiments, each battery compartment 2 can be equipped with a compartment control module. The electrical connector is electrically connected to the compartment control module, which is in turn connected to the control board. The compartment control module can control the corresponding electrical connector, compartment door, etc., within the battery compartment 2 to perform corresponding actions, completing battery swapping and monitoring operations.

[0037] In this embodiment, multiple battery compartment fans 4 are respectively configured one-to-one with multiple battery compartments 2, that is, each battery compartment 2 is equipped with one battery compartment fan 4. The battery compartment fans 4 are used to exhaust air from the corresponding battery compartment 2 into the cabinet 1. Cabinet fans 7 are installed inside the cabinet 1, and are used to exhaust air from the cabinet 1 to the outside of the cabinet 1 for air exchange. The multiple battery compartment fans 4 and the cabinet fans 7 work together to achieve the replacement of air in the battery compartments 2 and cabinet 1 with external air. Figure 1 As shown, the smoke sensor 12 is installed inside the cabinet 1, and the smoke sensor 12 is used to detect whether there is smoke inside the cabinet 1.

[0038] like Figure 3 As shown, the control board 11 is communicatively connected to multiple battery compartment fans 4, cabinet fans 7, and smoke sensors 12. When smoke is emitted from the battery compartment 2, the smoke can escape from the battery compartment 2 into the cabinet 1. When the smoke sensor 12 detects the smoke, it sends a smoke signal to the control board 11. Based on the smoke signal, the control board 11 controls the multiple battery compartment fans 4 and the cabinet fans 7 to start simultaneously, expelling the smoke from the battery compartment 2 and cabinet 1 to the outside of the cabinet 1. This allows for rapid smoke removal and reduces the risk of explosion. Specifically, the multiple battery compartment fans 4 expel the smoke from their respective battery compartment 2 into the cabinet 1, and the cabinet fans 7 ultimately expel the smoke to the battery swapping cabinet.

[0039] In this embodiment, the smoke sensor 12 is installed at the top inside the cabinet 1. Since smoke flows from low to high, when smoke appears in the battery compartment 2 at any location, it will pass through the smoke sensor 12 installed at a high position, thereby effectively detecting the smoke, realizing the exhaust of the smoke, and improving the safety of the battery swapping cabinet.

[0040] Furthermore, the cabinet fan 7 is located inside the cabinet 1 near the top, which facilitates the exhaust of air (such as smoke from combustible gases) inside the cabinet 1 to the outside of the cabinet 1, avoiding residues, etc.

[0041] In some embodiments, the smoke sensor 12 is a carbon monoxide sensor.

[0042] In some embodiments, the battery swapping cabinet further includes multiple battery compartment heaters 3, each corresponding to one of the multiple battery compartments 2. That is, each battery compartment 2 is also equipped with a corresponding battery compartment heater 3. The battery compartment heaters 3 are used to heat the air inside the cabinet 1, especially the air temperature near the battery compartment heaters 3. Maintaining a constant temperature inside the battery compartment 2 ensures that the internal temperature of the battery is at a suitable level, improving charging efficiency and battery life. The control board 11 can also communicate with the battery compartment heaters 3 and the battery compartment fan 4. After the battery is placed in the battery compartment 2, the battery communicates with the control board 11 to exchange data, such as uploading data on power level and internal temperature.

[0043] When there is a battery in battery compartment 2 but it is not fully charged, i.e., the battery is in a state of waiting to be charged or charging, the control board 11 interacts with the battery BMS to read that the internal temperature of the battery is less than or equal to a first temperature threshold. When the control board 11 reads that the internal temperature of the battery is less than or equal to a first temperature threshold, the control board 11 controls the corresponding battery compartment heater 3 and battery compartment fan 4 to start. The battery compartment heater 3 heats the air inside the cabinet 1, and the battery compartment fan 4 blows the heated air into the battery compartment 2 and exhausts the cold air inside the battery compartment 2 into the cabinet 1, forming a heating cycle to ensure that the temperature of the battery compartment 2 is at an appropriate temperature, so as to gradually increase the internal temperature of the battery, improve charging efficiency and battery life. When the control board 11 reads that the battery is fully charged or the internal temperature of the battery rises above a second temperature threshold, the control board 11 controls the battery compartment heater 3 to stop heating, and at the same time controls the battery compartment fan 4 to stop running as needed. The first temperature threshold and the second temperature threshold can be set according to the actual situation. In some embodiments, the first temperature threshold is 5°C and the second temperature threshold is 10°C.

[0044] like Figure 1 and Figure 2As shown, each battery compartment 2 is equipped with a battery compartment air inlet and a battery compartment air outlet 9. A battery compartment fan 4 is located outside the battery compartment air inlet, quickly blowing smoke and other air from the battery compartment 2 from the air inlet side to the air outlet 9 side, thus exhausting it into the cabinet 1. A battery compartment heater 3 is located between the battery compartment fan 4 and the battery compartment air inlet, quickly heating the air near the battery compartment air inlet. The battery compartment fan 4 is located outside the battery compartment heater 3, quickly blowing the heated air into the battery compartment 2 through the battery compartment air inlet, rapidly regulating the temperature inside the battery compartment 2. Preferably, the battery compartment air inlet and battery compartment air outlet 9 are located on opposite sides of the battery compartment 2 according to the fan's blowing direction. The battery compartment air inlet is located at the rear end of the battery compartment 2, where the rear space is larger, facilitating the installation of the battery compartment fan 4 and battery compartment heater 3, while also allowing them to be concealed, improving aesthetics. The battery compartment air outlet 9 is located at the top or bottom of the battery compartment 2 near the front end, which can conform to the airflow direction to achieve rapid air exchange without affecting the rotation of the compartment door or battery swapping. The battery compartment air inlet and outlet 9 can be multiple vents arranged in a matrix.

[0045] The battery swapping cabinet also includes multiple battery compartment temperature sensors 5. Each battery compartment temperature sensor 5 is installed one-to-one within a specific battery compartment 2, and is used to detect the temperature inside the battery compartment 2. That is, each battery compartment 2 has one battery compartment temperature sensor 5. In some embodiments, the battery compartment temperature sensor 5 is installed on the outside of the battery compartment 2, with its probe extending into the battery compartment 2 to detect the temperature inside the battery compartment 2.

[0046] like Figure 3 As shown, the control board 11 is communicatively connected to the battery compartment temperature sensor 5, which sends the real-time detected battery compartment temperature to the control board 11. When the temperature inside the battery compartment 2 exceeds a third temperature threshold, the control board 11 activates the battery compartment fan 4 to exchange air between the battery compartment 2 and the cabinet 1. Specifically, the battery compartment fan 4 blows air from the cabinet 1 into the battery compartment 2, and air from the battery compartment 2 is blown out of the cabinet 1. This air exchange lowers the temperature inside the battery compartment 2, creating a suitable temperature environment for charging.

[0047] The battery swapping cabinet also includes a cabinet temperature sensor 6, which is installed inside the cabinet 1, such as... Figure 1As shown. Cabinet temperature sensor 6 is used to detect the temperature inside cabinet 1. Cabinet fan 7 is used to blow air from inside cabinet 1 to the outside, reducing the temperature inside cabinet 1. Control board 11 is communicatively connected to cabinet temperature sensor 6 and cabinet fan 7. During the exchange of air between battery compartment 2 and cabinet 1, the temperature of the air inside cabinet 1 gradually increases, and cabinet temperature sensor 6 sends the detected temperature to control board 11. When the detected air temperature inside cabinet 1 exceeds a fourth temperature threshold, control board 11 controls cabinet fan 7 to start and exhaust the air from inside cabinet 1 to the outside. The third and fourth temperature thresholds can be set according to actual conditions. In some embodiments, the third and fourth temperature thresholds are 35°C.

[0048] In some embodiments, the cabinet temperature sensor 6 and the cabinet fan 7 are located inside the cabinet 1 near the top to facilitate air exchange and circulation. Figure 1 As shown, cabinet 1 is equipped with a cabinet air inlet 10 and a cabinet air outlet, which are located on the back of cabinet 1. The cabinet air inlet 10 is located near the bottom of cabinet 1, and the cabinet air outlet is located near the top of cabinet 1. Cabinet fan 7 is located near cabinet air outlet, and cabinet temperature sensor 6 is located near the top of cabinet 1.

[0049] This embodiment of the battery swapping cabinet includes a cabinet body, battery compartments housed within the cabinet, battery compartment fans, cabinet fans, smoke sensors, and a control board. Each battery compartment fan is paired with a corresponding battery compartment. When the smoke sensor detects smoke, it sends a smoke signal to the control board. Based on this signal, the control board simultaneously activates multiple battery compartment fans and cabinet fans to expel smoke from the battery compartments and cabinet body to the outside. This battery swapping cabinet utilizes the battery compartment fans and cabinet fans to quickly expel combustible gases, achieving air exchange within the cabinet, reducing the possibility of explosion, and minimizing losses.

[0050] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
