[0004] Currently, for the operation of the control system, the staff needs to frequently enter the processing bin for observation or operation, and the current energy storage charging box is too large and the space utilization rate is not high. With the frequent opening and closing of the processing bin, the temperature in the processing bin fluctuates greatly, resulting in excessive consumption of the expected ambient temperature in the bin, and it will also cause fluctuations in the charging and discharging of retired battery packs, shortening the reuse life of retired batteries and wasting certain resources. Especially when operating and repairing the control system, the ambient temperature of the processing bin quickly approaches the external ambient temperature. Under the premise that it cannot be quickly pulled back by the cooling system, the temperature of the battery pack at the bottom of the energy storage charging box cannot be in an ideal temperature charging and discharging environment, resulting in the reuse life of the battery pack at the bottom of the energy storage charging box being generally lower than the reuse life of the battery pack at the top of the energy storage charging box, and the replacement frequency is high, which is not conducive to controlling the cost of the energy storage station, and multiple maintenance is not conducive to the promotion and application of energy storage stations.

[0039] The pallets 10 are arranged in groups in the support frame at intervals along the height direction. The battery pack placement compartment 1 has a plurality of battery packs 001 stacked in the height direction. The number of the battery packs 001 is consistent with the number of the pallets 10. Each group of the battery packs 001 is correspondingly arranged on a group of pallets 10, so that the battery packs 001 can be driven to be taken out of or put back into the support frame.

[0040] The support frame includes a support base plate 11 and a support column 12. The support base plate 11 is supported by the support column 12 to form a plurality of battery pack cells stacked up and down for placing the battery pack 001. The spacing arrangement of the support base plate 11 can form a relatively closed battery pack cell.

[0043] Through the correspondingly arranged air outlet 16 and air return vent 17, the airflow path passes through the battery pack 001, so that the heat of the corresponding battery pack 001 is directly taken away, and the air return vent 17 also has a certain negative pressure, so that the cooling air is guided and forced to flow through the battery pack 001, thereby accelerating the cooling efficiency of the battery pack 001; when the battery pack 001 is assembled in the energy storage charging box, each group of battery packs 001 is equipped with a group of air outlets 16 and air return vents 17 of this solution, and the air outlet and return air both rely on the existing air conditioning cooling subsystem. Compared with the original air conditioning cooling system in the energy storage charging box, this solution can directly apply cooling air to the battery pack 001, reducing the battery pack 00 1. Differentiation of cooling at different positions can speed up the heat dissipation efficiency of the battery pack 001, increase the heat dissipation efficiency of the battery pack 001, control the temperature of the battery pack 001 within a preset range, and reduce the overheating and scrapping of the battery pack 001 due to inconsistent heat dissipation efficiency of the battery pack 001 in the energy storage charging box. At the same time, it can also improve the safety of the energy storage charging box, control the temperature of the entire box within the set range, and take into account the heat dissipation of each battery pack 001, so that the battery charging and discharging in the energy storage charging box can be in an ideal temperature charging and discharging environment, improve the reuse performance of waste batteries, ensure the service life of waste batteries in cascade utilization, and improve the quality of the energy storage charging box.

[0044] In the present embodiment, the middle part of the air outlet 16 in the height direction is higher than the middle part of the air outlet 16 in the height direction, and the middle part of the air outlet 16 in the height direction is close to the top surface of the battery pack 001; it can speed up the flow rate of the cooling air, improve the heat dissipation efficiency of the battery pack 001, and help maintain the temperature of the environment in which the battery pack 001 is located within an appropriate range. The purpose of the height difference between the air outlet 16 and the return air outlet 17 is to make the cooling air flow direction of the battery pack 001 tilt from top to bottom, which can further improve the cooling efficiency of the battery pack 001, further meet the function of efficient air cooling, and improve the service life of the battery pack 001.

[0045] In this embodiment, the air supply duct 14 extends in the height direction, and the air supply duct 14 is arranged on the longitudinal rear side of the placement bin. The air supply duct 14 has an air outlet 16. The air supply duct 14 is provided with an air induction plate 18 for guiding the gas to the air outlet 16. The purpose of setting the air induction plate 18 is to actively guide the cooling air to the corresponding air outlet 16, and try to control the flow of cooling air to each battery pack to be consistent, try to meet the heat dissipation consistency of each battery pack 001, meet the cooling consistency of each position of the energy storage charging box, reduce the upper and lower temperature difference in the energy storage charging box, so that the battery charging and discharging in the energy storage charging box can be in an ideal temperature charging and discharging environment, improve the reuse performance of waste batteries, and improve the quality of the energy storage charging box; the air induction plate 18 is provided with a diversion hole 19 or a diversion hole 19 is formed between the air induction plate 18 and the inner wall of the air supply duct 14; so that the cooling air can pass through the corresponding air outlet 16 and diffuse to the corresponding return air outlet 17 through each battery pack 001;

[0046] The number of the air outlets 16 of the air supply duct 14 is consistent with the number of the battery packs 001, and the air outlets 16 are arranged at the rear end of the battery pack 001 in a one-to-one correspondence with the battery packs 001; the number of the air induction plates 18 is consistent with the number of the air outlets 16, and the air induction plates 18 are arranged at the rear end of the air outlets 16 in a one-to-one correspondence with the air outlets 16;

[0049] In this embodiment, the diversion holes 19 staggered on the adjacent air duct plates 18 in the height direction have an overlapping area 20; the blowing method from top to bottom can obtain greater initial kinetic energy, which is beneficial to the heat dissipation of the battery pack 001. The setting of the overlapping area 20 can make the cooling air flowing in the height direction have sufficient wind pressure, and the cooling air delivered to the battery pack also has a certain wind pressure under the setting of the air duct plates 18, thereby achieving the purpose of autonomous air supply and return to each layer of battery packs.

[0050] In this embodiment, the air outlet 16 and the return air outlet 17 are arranged opposite to each other in the longitudinal direction, the middle part of the air outlet 16 in the height direction is higher than the middle part of the air outlet 16 in the height direction, and the middle part of the air outlet 16 in the height direction is close to the top surface of the battery pack 001;

Two air guide plates 18 are grouped together, and the stacking of the two is repeated downward. An overlapping area 20 is always reserved in the middle, so that the wind flow from top to bottom passes through each layer of air guide plates 18, and the cooling of each layer of battery packs is ensured to be consistent as much as possible.

[0052] The aperture sizes of the return air vents 17 gradually decrease from bottom to top; the setting of the return air vents 17 can actively guide the return air, improve the heat dissipation efficiency of the battery pack, and the size becomes smaller as it goes up, which can make up for the controllable temperature difference caused by insufficient output pressure of some bottom air outlets 16, further ensure the ambient temperature in the energy storage charging box, and ensure the operating temperature of each battery pack 001.
