Description

Technical Field

[0001] The present invention relates to the field of formation and grading control, and particularly relates to a temperature control system and method based on a formation and grading system. Background Art

[0002] Generally, it is necessary to perform formation and grading on batteries in the later stage of the battery production stage. This step requires ensuring the temperature rise of the battery storage location and the uniform temperature of the batteries, thereby ensuring the consistency of the performance of batteries in the same batch. Then, in the actual production process, the same production equipment often deals with different types of batteries at the same time. Also, because the heat dissipation capacity of a conventional battery cabinet is not adjustable, different types of batteries cannot be produced at the best temperature simultaneously.

[0003] In addition, there are many processes in the formation and grading process of batteries, and the heat generation in each process is different. Consequently, the heat dissipation capacity required by the battery cabinet in each process is also different. There is a contradiction between the heat dissipation capacity required by the production environment and the heat dissipation capacity that the equipment can provide, and it also causes waste of energy and increases the operating cost.

[0034] Refer to Figure 2 Shown is a schematic diagram of unit connections according to a preferred embodiment of the present invention, which further shows the connection relationships of the functional units in different modules on the basis of Figure 1 That is:

[0035] The startup module further includes a data import unit for importing initial information; a fan setting unit connected to the data import unit for interaction, which is used to call the preset start-stop mode in the initial information and set the fan start-stop mode based on this mode; an execution unit connected to the data import unit for interaction, which is used to call the process data in the initial information and generate execution data based on this data; a startup unit connected to the fan setting unit and the execution unit respectively for interaction, which is used to call the execution data and the fan startup mode, and then start the system according to this data and mode; the initial information mentioned here includes process data and preset start-stop mode, and such information can be increased, decreased or modified according to the needs of the actual production environment; the execution data includes the theoretical total heat generation of the storage locations in each process and the fan speed in each process, and such data is obtained through theoretical calculation or analysis of actual production experience and can be input into the system as initial information.

[0036] The acquisition module further includes: a storage location temperature acquisition unit connected to the startup unit in the startup module for interaction, which is used to acquire the temperatures of different areas in the storage location and generate storage location temperature data; a battery temperature acquisition unit connected to the startup unit in the startup module for interaction, which is used to acquire the temperatures of each battery in the storage location and generate battery temperature data; the storage location temperature data and the battery temperature data mentioned here together constitute the temperature data; there is at least 1 storage location temperature acquisition unit, and the actual number is determined based on information such as the size of the storage location and the temperature acquisition coverage, and it is generally arranged in different areas of the storage location to measure and reflect the actual temperature in the storage location; there is at least 1 battery temperature acquisition unit, and at least 1 battery corresponds to 1 battery temperature acquisition unit. If the production requirements are met, 1 battery temperature acquisition unit can also correspond to multiple batteries, and its actual installation quantity is determined based on the application scenario and data requirements.

[0037] The analysis module further includes: a storage location average temperature analysis unit connected to the storage location temperature acquisition unit in the acquisition module for interaction, which is used to call and analyze the storage location temperature data and then obtain the storage location average temperature value; a battery average temperature analysis unit connected to the battery temperature acquisition unit in the acquisition module for interaction, which is used to call and analyze the battery temperature data and then obtain the battery average temperature value; a battery temperature difference analysis unit connected to the battery average temperature analysis unit and the battery temperature acquisition unit in the acquisition module respectively for interaction, which is used to call the battery average temperature value and the battery temperature data, and obtain the battery temperature difference data between each battery and the battery average temperature value based on the above data analysis; an environmental temperature difference analysis unit connected to the storage location average temperature analysis unit and the battery average temperature analysis unit respectively for interaction, which is used to call the storage location average temperature value and the battery average temperature value, and obtain the environmental temperature difference data based on the above data analysis; the battery temperature difference data and the environmental temperature difference data together constitute the temperature difference data in the system.

[0038] The temperature control module further includes: an air conditioner temperature control unit, which is connected to the ambient temperature difference analysis unit in the analysis module for interaction and is used to control the ambient temperature. If the absolute value of the ambient temperature difference data is higher than the preset ambient temperature difference value, the air supply temperature value of the air conditioner is reduced. If the absolute value of the ambient temperature difference data is lower than or equal to the preset ambient temperature difference value, the current air supply temperature of the air conditioner is maintained, and the fan temperature control unit is further enabled; a fan temperature control unit, which is respectively connected to the air conditioner temperature control unit and the battery temperature difference analysis unit in the analysis module for interaction and is used to control the battery temperature. If the absolute value of the battery temperature difference data is higher than the preset battery temperature difference value, the speed of the fan corresponding to the battery is adjusted. If the absolute value of the battery temperature difference data is lower than or equal to the preset battery temperature difference value, the current speed of the fan is maintained.

[0039] Referring to Figure 3 As shown, the schematic diagram of the method flow according to the preferred embodiment of the present invention includes the following steps: S1. Set the fan start-stop mode and generate execution data, and then start the system; S2. Collect temperature data; S3. Call and analyze the temperature data, and then obtain the temperature difference data; S4. Adjust and control the temperature based on the temperature difference data.

[0040] Referring to Figure 4 As shown is the schematic diagram according to the specific embodiment A of the present invention. Embodiment A shows that in a storage location with 16 batteries arranged, in order to meet the temperature control effect of the batteries, 8 fans are arranged at the same time, and each fan corresponds to 2 batteries; in the actual production process, the ambient temperature for battery grading is generally 25°C. Assuming that the capacity of each battery is 220Ah, the battery grading process is as follows: Shelve for 1 min; Constant current discharge at 60A until the voltage cuts off to 2.5V; Shelve for 1 min; Constant current charge at 120A for 80 min; Shelve for 1 min; Constant current charge at 22A for 40 min; Shelve for 1 min; Constant current charge at 11A for 20 min; Shelve for 1 min; Constant current discharge at 120A for 90 min...

[0041] Since the above process first feeds back to the fan temperature control unit, that is, at the fan, for the preliminary adjustment of the fan speed according to the functional relationship between the battery heat generation and the charge-discharge curve and the functional relationship between the fan speed and the air volume. At this time, the speeds of all fans are the same; in the actual cabinet, due to the blocking effects of cylinders, wire grooves, probe assemblies, temperature acquisition components, etc., it is impossible to make the actual cooling air volume of each battery consistent. For example, in the process of constant current discharge at 120A, first, according to the temperatures of each battery, the average temperature of the batteries in the tray is obtained as 32°C, and the difference between the average temperature value of the storage location and the average temperature value of the batteries is calculated to obtain the ambient temperature difference data, that is, the temperature rise data; if the battery is within the temperature rise range allowed by the battery manufacturer, the following operations are carried out. If the absolute value of the battery temperature difference data of each battery is within the range allowed by the battery manufacturer, no fan adjustment is made. If not, fan adjustment is made.

[0042] If the battery temperature at the air inlet is around 29°C and the battery temperature at the air outlet is 35°C, the control algorithm is used to finely adjust the fan speed at this time, so that the temperatures of different batteries approach the average battery temperature value, and the absolute value of the battery temperature difference data of each battery is within the range required by the battery manufacturer.

[0043] If the temperature rise data does not meet the requirements of the battery manufacturer, the air supply temperature of the air conditioner is adjusted at this time, and the adjustment value of the air inlet temperature of the air conditioner is the value by which the temperature rise data exceeds the preset temperature of the battery manufacturer.

[0044] In each process of the grading and formation process of lithium batteries, the above process is repeated; when the battery manufacturer changes the production battery and the batteries in the tray change from 2×8 to 2×12, the position of the fan is adjusted first to make the fan correspond to the equal amount of batteries, and then the above steps are repeated for temperature control.
