Any modification of the structure, change of the proportional relationship, or adjustment of the size, without affecting the effects that the present utility model can produce and the purposes that can be achieved, should still fall within the scope covered by the technical content disclosed in the present utility model.

[0037] Please refer to Figures 1 to 4 , the present utility model discloses an activation device for battery performance, which can improve the problem that the temperature of the working environment of the current battery pack is unstable, resulting in the reduction of the performance of the battery pack. Among them, the activation device for battery performance can be applied to automobiles or battery swapping stations to improve the performance of the batteries in automobiles or battery swapping stations during actual use through the activation device for battery performance. However, it is not limited thereto, and the specific application scenarios of the activation device for battery performance can be determined according to actual needs.

[0038] Specifically, the activation device for battery performance includes a battery frame 100, a battery pack 200, a water supply unit 300, and a controller. Among them, the battery frame 100 can be a frame structure connected by a plurality of brackets, and the battery frame 100 at least includes a first connection surface 110 and a second connection surface 120. The first connection surface 110 and the second connection surface 120 can be parallel to each other, and the battery pack 200 is arranged on the first connection surface 110, and the water supply unit 300 and the controller are respectively connected to the second connection surface 120.

[0039] In some embodiments, a plurality of battery packs 200 are provided, and the battery packs 200 are located on the first connection surface 110. Each single battery pack 200 includes at least one battery box 210, and a battery pack is stored in the battery box 210. When each single battery pack 200 includes a plurality of battery boxes 210, the plurality of battery boxes 210 are stacked on the first connection surface 110.

[0040] It should be noted that an interlayer cavity 211 is provided on the inner wall of the battery box 210, and a water inlet pipe 330 and a water outlet pipe 340 are communicated in the interlayer cavity 211. It can be understood that the water inlet pipe 330 and the water outlet pipe 340 are respectively connected to the water supply unit 300. Through the water supply unit 300, it can be realized that after the liquid enters the interlayer cavity 211 from the water inlet pipe 330, it returns to the water supply unit 300 through the water outlet pipe 340. Furthermore, the circulation of the liquid between the water supply unit 300 and the interlayer cavity 211 is realized. It is allowed to regulate the temperature of the liquid entering the interlayer cavity 211 to ensure the ambient temperature of the battery pack in the battery box 210. Therefore, a heating module 600 can be connected to the pipeline of the water inlet pipe 330, and the heating module 600 is controlled and connected to the controller. Through the controller, the working condition of the heating module 600 is regulated to realize heating the temperature in the water inlet pipe 330.

[0041] Furthermore, the heating module 600 is a positive temperature coefficient heater, and the heating module 600 can be used to heat the liquid in the water inlet pipe 330. Among them, the positive temperature coefficient heater can automatically adjust the heat generation according to the ambient temperature, avoid unnecessary energy waste, and realize high efficiency and energy saving. The positive temperature coefficient heater can automatically reduce the power when overheated, prevent overheating damage, and improve the safety of use. And the positive temperature coefficient heater can also realize precise temperature control to meet the requirements of various occasions that need precise temperature control.

[0042] In order to improve the accurate control of the temperature of the battery pack in the battery box 210, at least one temperature sensor can be provided in the battery box 210. The temperature sensor is electrically connected to the controller, and the controller can obtain the temperature data in the battery box 210 in time through the temperature sensor.

[0043] Based on this, when the temperature in the battery box 210 obtained by the temperature sensor is lower than a preset threshold, the controller regulates the heating module 600 to heat the liquid in the water inlet pipe 330 to increase the temperature in the battery box 210 until the temperature sensor in the battery box 210 senses that the temperature in the battery box 210 is within a suitable range.

[0044] In some embodiments, the water supply unit 300 includes a water pump 310 and a water tank 320. The water inlet pipe 330 is connected to the water outlet of the water pump 310, and the water outlet pipe 340 is communicated with the water tank 320. In order to improve the connection effect between the water inlet pipe 330 and the battery box 210, a control valve 400 can be provided at the connection between the battery box 210 and the water inlet pipe 330. Through the control valve 400, the on-off between the water inlet pipe 330 and the battery box 210 is regulated.

[0045] In some embodiments, to improve the performance of the present device during actual use, a cooling module 500 may be provided. The cooling module 500 is electrically connected to the controller, and at the same time, the cooling module 500 is also connected to the pipeline of the water inlet pipe 330.

[0046] Specifically, the cooling module 500 includes a condenser 510, a condensation fan 520, and a plate heat exchanger 530. Among them, the condenser 510 is fixedly connected to the battery frame 100, and the condensation fan 520 is fixedly connected to the condenser 510. The plate heat exchanger 530 is located on one side of the condenser 510, and the water inlet pipe 330 is connected to the plate heat exchanger 530. When the water inlet pipe 330 passes through the plate heat exchanger 530, the temperature inside the water inlet pipe 330 can be adjusted through the plate heat exchanger 530. When the low-temperature liquid in the water inlet pipe 330 enters the interlayer cavity 211, the temperature inside the battery box 210 can be reduced. At the same time, the temperature inside the battery box 210 is detected according to the temperature sensor until the temperature inside the battery box 210 is within the appropriate range of the battery pack.

[0047] The present utility model also discloses an automobile, which includes an activation device for battery performance as disclosed in the above embodiments. Through the activation device for battery performance, it can ensure that the battery of the automobile maintains a high-performance state during use.

[0048] The present utility model also discloses a battery swapping station, which includes an activation device for battery performance as disclosed in the above embodiments. Through the activation device for battery performance, it can ensure that the batteries in the battery swapping station maintain a high-performance state during use.

[0049] In summary, the present utility model discloses an activation device for battery performance and an automobile and a battery swapping station to which it is applied. After the liquid enters the interlayer cavity 211 from the water inlet pipe 330 through the water supply unit 300, it can return to the water supply unit 300 from the water outlet pipe 340 to realize circulation. The controller, based on the temperature sensor, regulates the working conditions of the heating module 600 and the cooling module 500 to heat or cool the temperature of the water inlet pipe 330. By regulating the temperature of the liquid entering the interlayer cavity 211, the ambient temperature of the battery pack in the battery box 210 is adaptively adjusted.

[0050] Therefore, it can effectively improve the problem that the temperature of the working environment of the current battery pack is unstable, resulting in a reduction in the energy of the battery pack. Therefore, the present utility model effectively overcomes some practical problems in the prior art and thus has high utilization value and practical significance.
