If the heat dissipation space is left only to meet the minimum condition that the battery does not overheat and damage, the remaining space is filled with batteries.

The electrical socket 9 is specifically divided into a discharging socket and a plurality of charging sockets, and the plurality of charging sockets can be externally connected with plugs for charging at the same time, so that the charging efficiency of the battery pack is doubled.

[0040] The grid slot 3 arranged in the energy storage device body 1 is positioned and installed, the grid slot 3 includes a bottom plate and a grid plate fixed in four directions above the bottom plate, and two rows of battery panels 2 are placed in the grid slot 3. The bottom of each row of battery panels 2 is provided with two symmetrically distributed L-shaped rail plates 4, and the L-shaped rail plates 4 are fixed on the bottom plate of the grid slot 3.

[0050] The scattering tool 23 includes a small concave frame 36 fixed on the grid slot 3, a range increasing shaft 35 and a multi-adjusting shaft 34 supported on the small concave frame 36, and a split gear 37 fixed on the transposition tool 24. The range increasing shaft 35 is in perpendicular transmission with the multi-adjusting shaft 34 at one end. The range increasing shaft 35 is in meshing transmission with an arc-shaped rack arranged on the fan frame 26 through a fixed shaft gear at the other end. The multi-adjusting shaft 34 and the range increasing shaft 35 are respectively movably sleeved in different through holes arranged on the small concave frame 36. The multi-adjusting shaft 34 is in meshing transmission with a bevel gear fixed on the range increasing shaft 35 through a fixed ring bevel gear.

[0051] The transposition tool 24 includes a rail seat 38 fixed on the grid slot 3, an I-shaped long column 39 sliding through a T-shaped slot arranged on the rail seat 38, a cross plate 41 vertically arranged at one end of the I-shaped long column 39, and a homing spring piece 40 fixed on the end of the I-shaped long column 39. The homing spring piece 40 presses the cross plate 41 at one end. The cross plate 41 slides through a plate hole arranged on the end of the I-shaped long column 39. The cross plate 41 hooks the concave frame seat 13 at one side of the end. The other side of the end of the cross plate 41 is provided with an inclined surface for resetting. The I-shaped long column 39 is in meshing transmission with the split gear 37 through a row of teeth arranged thereon.

[0052] The swing tool 20 includes an inclined frame 43, a double adjusting plate 44 vertically fixed at one end of the inclined frame 43, and a mainspring 42 fixedly sleeved on a protrusion column arranged on the pile plate frame 21. The outer end of the mainspring 42 is fixed on the double adjusting plate 44. The protrusion column of the pile plate frame 21 is movably sleeved in a through hole arranged on the inclined frame 43. The shaft body of the disc roller 19 is movably sleeved in a through hole arranged on the other end of the inclined frame 43.

[0053] The air valve 22 includes an L-shaped rack 45 fixedly engaged with the end of the double adjusting plate 44, an extension column 46 fixedly connected with one end of the L-shaped rack 45, a cylinder 47 slidably inserted into the other end of the extension column 46, and a valve plate 48 covering the end of the cylinder 47. The cylinder 47 is fixed on the stake plate frame 21, and a small hole is formed in the middle of the valve plate 48. The valve plate 48 is fixed on the stake plate frame 21 by a spring on one side.

[0054] The motor driving mechanism in the prior art is arranged in the energy storage device body 1 to drive the integrated shaft 15. The integrated shaft 15 drives the fan shaft 14 to rotate the fan 16 to blow air, so that the heat dissipation airflow blows to the end of the battery plate set 2 to cool the plate surface of the battery 12. Specifically, the airflow blows to one side of the plate surface of the battery 12. When the airflow blows to the other side of the plate surface of the battery 12, the battery 12 is transported to the other end of the other battery plate set 2.

[0055] The integrated shaft 15 drives the head shaft 33 to rotate the ratchet wheel 32 slowly. When the protrusion on the ratchet wheel 32 meets the press column 29, the press column 29 is pushed, and the tail shaft 28 is rotated. Then, the fan frame 26 is swung to rotate the range increasing shaft 35 for several turns. The multiple adjusting shaft 34 drives the gear 37 to rotate, which causes the I-shaped column 39 to translate. The I-shaped column 39 pulls the cross plate 41, which is translated to hook the concave frame seat 13 on the battery plate set 2. Specifically, the battery plate set 2 is hooked, and the battery plate set 2 is transported to the end of the other battery plate set 2. In addition, after the battery plate set 2 is transported to the other battery plate set 2, the next battery plate set 2 is transported after a period of time. Because the press column 29 is pushed once every turn of the ratchet wheel 32, the ratchet wheel 32 needs enough time to rotate a full circle. The time for the ratchet wheel 32 to rotate a full circle corresponds to the interval time for the battery plate set 2 to be transported.

[0056] After the battery plate set 2 at the end of the battery plate set 2 is transported to the other battery plate set 2, the battery plate set 2 is transported in the opposite direction on the other battery plate set 2. Specifically, the battery plate set 2 is transported in the opposite direction by the pressing of the disc roller 19. When the battery plate set 2 is transported, the battery plate set 2 pushes the disc roller 19 in the opposite direction. The disc roller 19 swings away from the grid slot 3, and the inclined frame 43 swings synchronously with the disc roller 19. The spring 42 is contracted to store energy. When the battery plate set 2 is transported, the spring 42 releases the pressure. The inclined frame 43 swings in the opposite direction to drive the disc roller 19. The disc roller 19 presses the battery plate set 2 at the end, which causes the whole battery plate set 2 to translate in the opposite direction.

[0057] The air valve 22 is designed to limit the swing of the double adjusting plate 44. Referring to Figure 15, because air in the cylinder 47 is quickly forced out behind the valve flap 48 as the telescoping post 46 is inserted into the cylinder 47, and the counterclockwise rotation of the double tuning plate 44 is slow because air is only able to be replenished into the cylinder 47 through the air bleed hole in the valve flap 48 as the telescoping post 46 is withdrawn from the cylinder 47, to summarize the air valve 22 restricts the rotation of the double tuning plate 44, the double tuning plate 44 controls the ramp 43, the ramp 43 drives the disc roller 19, so the disc roller 19 swings away from the grate slot 3 quickly, and the disc roller 19 returns to the grate slot 3 slowly, so the disc roller 19 pushes the row of battery plates 2 slowly and gently.

[0058] While embodiments of the application have been shown and described, it is to be understood that the application is not limited to these embodiments. Rather, it is the intention that modifications, changes, substitutions, and variations be made to the embodiments without departing from the spirit and scope of the application, which is defined solely by the claims and their equivalents.
