[0030] 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 heaters 3, multiple battery compartment fans 4, 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.
[0031] 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.
[0032] 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.
[0033] In this embodiment, multiple battery compartment heaters 3 and multiple battery compartment fans 4 are respectively arranged in a one-to-one correspondence with multiple battery compartments 2, that is, each battery compartment 2 is equipped with one battery compartment heater 3 and one battery compartment fan 4. 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. The battery compartment fans 4 are used to blow the heated air into the corresponding battery compartment 2, while simultaneously exhausting the cold air inside the battery compartment 2 back into the cabinet 1, thereby forming a heating cycle to ensure that the temperature inside the battery compartment 2 reaches the required temperature, such as around 35°C. 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.
[0034] like Figure 1 and Figure 2 As shown, each battery compartment 2 is equipped with a battery compartment air inlet 8 and a battery compartment air outlet 9. A battery compartment heater 3 is located outside the battery compartment air inlet 8, which can quickly heat the air near the battery compartment air inlet 8. A battery compartment fan 4 is located outside the battery compartment heater 3, which can quickly blow the heated air into the battery compartment 2 through the battery compartment air inlet 8, rapidly regulating the temperature inside the battery compartment 2. Preferably, the battery compartment air inlet 8 and battery compartment air outlet 9 are located on opposite sides of the battery compartment 2 according to the airflow direction of the fan. The battery compartment air inlet 8 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, and 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, conforming to the airflow direction for rapid air exchange without affecting the rotation of the compartment door or battery swapping. The battery compartment air inlet 8 and battery compartment air outlet 9 can be multiple vents arranged in a matrix.
[0035] The control board 11 is communicatively connected to the battery compartment fan 4 and the battery compartment heater 3. 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.
[0036] 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.
[0037] The battery swapping cabinet also includes multiple battery compartment temperature sensors 5, such as Figure 2 As shown, multiple battery compartment temperature sensors 5 are arranged one-to-one within multiple battery compartments 2. The battery compartment temperature sensors 5 are used to detect the temperature inside the battery compartment 2. That is, each battery compartment 2 is equipped with 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.
[0038] 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.
[0039] The battery swapping cabinet also includes a cabinet temperature sensor 6 and a cabinet fan 7, both of which are located inside the cabinet 1. 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.
[0040] 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.
[0041] This embodiment of the battery swapping cabinet includes a cabinet, a battery compartment housed within the cabinet, a battery compartment heater, a battery compartment fan, and a control board. The battery compartment heater and fan are configured to correspond one-to-one with the battery compartment. The control board is configured to, when detecting that the battery is in a state of waiting to be charged or charging and the battery's internal temperature is less than or equal to a first temperature threshold, control the battery compartment heater to heat the air inside the cabinet and control the battery compartment fan to blow the heated air into the battery compartment and exhaust the cold air inside the battery compartment back into the cabinet. The control board is also configured to, when the battery is fully charged or the battery's internal temperature is greater than or equal to a second temperature threshold, control the battery compartment heater to stop heating. This battery swapping cabinet, without significantly increasing costs, places the battery in a suitable charging temperature environment, improving charging efficiency and reducing safety risks.
