The battery charging and discharging in the energy storage charging box can be in an ideal temperature charging and discharging environment, improve the performance of the waste battery, ensure the service life of the waste battery, and improve the quality of the energy storage charging box.

[0044] In the 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. The flow rate of the cooling air can be accelerated, the heat dissipation efficiency of the battery pack 001 can be improved, and the temperature of the environment in which the battery pack 001 is located can be maintained within a suitable range. The purpose of the height difference between the air outlet 16 and the air return 17 is to make the cooling air flow direction of the battery pack 001 inclined from top to bottom, which can further improve the cooling efficiency of the battery pack 001, further satisfy the function of efficient air cooling, and prolong the service life of the battery pack 001.

[0045] In this embodiment, the air supply pipeline 14 extends in the height direction, is arranged at the longitudinal rear side of the placement bin, has an air outlet 16, and is provided with an air guide plate 18 for guiding gas to the air outlet 16. The air guide plate 18 is arranged to actively guide cooling air to the corresponding air outlet 16, to control the flow of cooling air to each group of battery packs as much as possible, to meet the heat dissipation consistency of each battery pack 001 as much as possible, to meet the cooling consistency of each position of the energy storage charging box, to reduce the temperature difference between the upper and lower parts of the energy storage charging box, to enable the battery charging and discharging in the energy storage charging box to be in an ideal temperature charging and discharging environment, to improve the reuse performance of waste batteries, and to improve the quality of the energy storage charging box. The air guide plate 18 is provided with a shunt hole 19, or the air guide plate 18 and the inner wall of the air supply pipeline 14 form a shunt hole 19, so that the cooling air can pass through the corresponding air outlet 16 and diffuse to the corresponding air return port 17 through each group of battery packs 001.

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

[0047] The air return pipeline 15 extends in the height direction, is arranged at the longitudinal front side of the placement bin, and the number of air return ports 17 of the air return pipeline 15 is consistent with the number of battery packs 001.

[0048] In this embodiment, the air guide plate 18 is inclined downward from back to front, and the shunt hole 19 is arranged on the air guide plate 18. The inclined arrangement of the air guide plate 18 can improve the initial kinetic energy of the cooling air entering the battery pack, and the staggered arrangement of the shunt holes 19 on the adjacent air guide plates 18 in the height direction can ensure that the cooling air enters the next level at the bottom. The shunt holes 19 on the air guide plates 18 in the height direction are staggered, so that the cooling air entering the next level has initial kinetic energy after being stored, and then diffuses downward step by step. The air guide plate 18 at the bottom can not have a shunt hole 19 and directly guide air to the corresponding battery pack for cooling.

[0049] In this embodiment, the shunt holes 19 arranged on the adjacent air guide plates 18 in the height direction are staggered and have an overlapping area 20. The upward blowing method can obtain greater initial kinetic energy, which is beneficial to heat dissipation of the battery pack 001. The arrangement of the overlapping area 20 can make the cooling air flowing in the height direction have sufficient air pressure, and the cooling air supplied to the battery pack also has a certain air pressure under the arrangement of the air guide plate 18, thereby achieving the purpose of independently supplying and returning air to each layer of battery pack.

[0050] In this embodiment, the air outlet 16 and the air return port 17 are longitudinally opposite, 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;

[0051] The shunt holes 19 on the air guide plate 18 are several, the aperture size of the several shunt holes 19 gradually decreases from front to back, and the distance between adjacent through holes gradually increases from front to back; the closer the shunt hole 19 is to the air outlet 16, the smaller the size and the farther the distance, the greater the kinetic energy of the air outlet, which ensures the cooling capacity of the battery pack 001, and in this scheme, as shown, it shows the position of the shunt hole 19 on the two air guide plates 18 from top to bottom, and the two air guide plates 18 are a group, and the stacking of the two is repeated downward, and the middle part always reserves an overlapping area 20, so that the air flow from top to bottom passes through each layer of air guide plate 18, and the cooling of each layer of battery pack is ensured as much as possible. Figure 5

[0052] The aperture size of the several air return ports 17 gradually decreases from bottom to top; the setting of the air return port 17 can actively guide the air return, improve the heat dissipation efficiency of the battery pack, and the size becomes smaller and smaller upwards, which can make up for the controllable temperature difference caused by the insufficient output pressure of the bottom air outlet 16, further ensure the environment temperature in the energy storage charging box, and ensure the use temperature of each battery pack 001.

[0053] In this embodiment, as shown in the figure, Figure 3 The energy storage charging box is arranged with two groups of battery packs 001 in the transverse direction, and the support column 12 includes several support columns in the middle, on both sides and at the rear end of the two groups of battery packs 001;
