Description

Technical Field

[0001] The present application relates to the field of energy storage technology, and in particular to an energy storage box and an energy storage device. Background Art

[0002] Energy storage devices have been widely used due to their large electrical energy storage capacity. Energy storage devices usually include an energy storage box and multiple batteries installed in the energy storage box. Batteries will release flammable gas when thermal runaway occurs. The high-temperature gas will accumulate in the energy storage box, which will affect the reliability of the energy storage device. Therefore, a ventilation system needs to be installed on the energy storage box.

[0003] In the prior art, the ventilation system of the energy storage box is prone to airflow short-circuiting, resulting in poor ventilation effect and reduced reliability of the energy storage device. Utility Model Content

[0004] In view of the above problems, the present application provides an energy storage box and an energy storage device, which solve the problem that the ventilation system of the energy storage box is prone to airflow short circuit.

[0005] The first aspect of the present application provides an energy storage box, the energy storage box comprising:

[0008] In the present application, the air inlet is arranged on the first side wall, and the air outlet is arranged on the second side wall. At the same time, the air inlet is arranged outside the projection area of ​​the air outlet on the first side wall. By setting the air inlet and the air outlet, the flow path of the airflow in the energy storage box is extended, the airflow short circuit is reduced, and the ventilation effect of the energy storage box is improved.

[0009] In some embodiments of the present application, at least one of the air inlet and the air outlet is provided with a water-blocking component. The water-blocking component is used to block rainwater and the like, thereby reducing the situation where rainwater enters the interior of the energy storage box, thereby reducing the potential safety hazards caused by water ingress into the energy storage box.

[0010] In some embodiments of the present application, the air inlet is provided with a water-blocking component, which is provided outside the energy storage box and at least shields the top of the air inlet. The water-blocking component is provided above the air inlet, thereby reducing the situation where the airflow carries rainwater and the like into the energy storage box during the process of entering through the air inlet, and further reduces the potential safety hazards caused by water ingress into the energy storage box.

[0011] In some embodiments of the present application, the water retaining component includes a shell, the shell has an air inlet channel, the water retaining component is connected to the first side wall, the outlet of the air inlet channel is connected to the air inlet, and the direction of the inlet of the air inlet channel is set at a preset angle to the ground on which the energy storage box is installed, and the preset angle is greater than or equal to zero degrees and less than or equal to ninety degrees.

[0013] In some embodiments of the present application, the pore density of the filter element is in the range of 15 PPI to 30 PPI, where PPI is the average number of pores per unit inch. By setting the pore density of the filter element, the resistance to the airflow process can be reduced while taking into account the filtering effect.

[0014] In some embodiments of the present application, the filter element is a filter net or a filter foam.

[0104] Energy storage devices have been widely used due to their advantages such as large energy storage capacity. Energy storage devices usually include an energy storage box and multiple batteries arranged in the energy storage box. Batteries will release flammable gas when thermal runaway occurs. The accumulation of high-temperature gas in the energy storage box will affect the reliability of the energy storage device. Therefore, a ventilation system needs to be provided on the energy storage box. In the related art, the ventilation system of the energy storage box is prone to airflow short circuit, resulting in poor ventilation effect and reducing the reliability of the energy storage device.

[0105] In the present application, the energy storage box includes a first side wall and a second side wall, at least one air inlet is provided on the first side wall, at least one air outlet is provided on the second side wall, and the second side wall is arranged parallel to and spaced from the first side wall along a first direction (the first direction is the length direction or width direction of the energy storage box), the air outlet has a projection on the first side wall, and any air inlet is arranged outside the projection area. In the present application, the air inlet is arranged on the first side wall, and the air outlet is arranged on the second side wall, and at the same time, the air inlet is arranged outside the projection area of ​​the air outlet on the first side wall. By arranging the air inlet and the air outlet, the flow path of the airflow in the energy storage box is extended, the airflow short circuit is reduced, and the ventilation effect of the energy storage box is improved.

[0106] According to some embodiments of the present application, the energy storage device includes an energy storage box and a battery. A battery compartment is provided inside the energy storage box, a battery bracket is provided inside the battery compartment, the batteries are arranged on the battery bracket, and the batteries are arranged in a rectangular array in the battery compartment to accommodate a large number of batteries in the battery compartment.

[0107] The battery can be a battery cell, a battery module or a battery pack.

[0108] A battery cell is the smallest unit in a battery, and a battery cell may include but is not limited to a lithium-ion battery, a sodium-ion battery, or a magnesium-ion battery, etc. The shape of a battery cell includes but is not limited to a cylinder, a flat body, a rectangular parallelepiped, or other shapes, etc.

[0109] The battery module includes a plurality of battery cells, and the plurality of battery cells are connected in series and / or in parallel via electrode terminals.

[0110] The battery pack may include multiple battery cells or multiple battery modules. When the battery pack includes multiple battery cells, the multiple battery cells are connected in series and / or in parallel via electrode terminals. When the battery pack includes multiple battery modules, the multiple battery modules are connected in series and / or in parallel.

[0111] The energy storage box can be a simple three-dimensional structure such as a single cuboid, cylinder or sphere, or a complex three-dimensional structure composed of simple three-dimensional structures such as cuboids, cylinders or spheres. The material of the energy storage box can be alloy materials such as steel, iron, aluminum alloy, iron alloy, etc., or polymer materials such as polycarbonate, polyisocyanurate foam plastics, or composite materials such as glass fiber and epoxy resin.

[0112] In some embodiments of the present application, Figures 1 to 10 As shown, an energy storage box 10 is proposed, which includes a first side wall 11 and a second side wall 12. At least one air inlet 111 is provided on the first side wall 11, and at least one air outlet 151 is provided on the second side wall 12. Along a first direction a, the second side wall 12 is spaced apart from the first side wall 11, and the air outlet 151 has a projection on the first side wall 11, and any air inlet 111 is arranged outside the projected area, wherein the first direction a is the length direction or width direction of the energy storage box 10.

[0113] In this embodiment, the energy storage box 10 is a rectangular structure (such as a container structure, etc.), which has a length direction, a width direction and a height direction, and the length direction, the width direction and the height direction are perpendicular to each other. When the energy storage box 10 is placed on the ground, the length direction and the width direction are parallel to the ground, and the height direction is perpendicular to the ground.

[0114] Specifically, when the energy storage box 10 is used in the energy storage device 100, the external airflow enters the interior of the energy storage box 10 through the air inlet 111 and flows in the energy storage box 10, so that the air inside the energy storage box 10 is finally discharged through the air outlet 151, thereby realizing ventilation of the energy storage box 10, so as to reduce the accumulation of combustible gas in the energy storage box 10, thereby improving the safety performance of the energy storage device 100.

[0115] In the present application, the air inlet 111 is arranged on the first side wall 11, and the air outlet 151 is arranged on the second side wall 12, and the air inlet 111 is arranged outside the projection area of ​​the air outlet 151 on the first side wall 11. By arranging the air inlet 111 and the air outlet 151, the flow path of the airflow in the energy storage box 10 is extended (such as Figure 4 The curved arrow line shown is the airflow direction c) in the energy storage box, which reduces the airflow short circuit and thus improves the ventilation effect of the energy storage box 10.

However, the setting of the filter 172 will generate resistance to the flow of airflow. In the present application, by setting the pore density of the filter 172, the resistance to the airflow during the flow process is reduced while taking into account the filtering effect.
