Problems solved by technology

Lithium-ion batteries generate heat during the charging and discharging process. When the batteries are connected in series and parallel, due to the small gap between the batteries and the insufficient ventilation of the box, there will be a large temperature difference between the cells.
Lithium-ion batteries are greatly affected by temperature. When

Example Embodiment

[0024] The improved battery box of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0025] Such as Image 6 As shown, the improved battery box includes a box body 1 and two battery modules placed in the box body. The two battery modules are arranged on opposite sides of the box body 1 in parallel. Such as Figure 8 As shown, the box body 1 is composed of four side panels, a box cover and a box bottom. Two parallel side panels serve as the air inlet plate 2 of the battery box. The air inlet plate 2 is provided with a plurality of air inlets 10 The area occupied by the air inlet on the air inlet plate is adapted to the width of the battery pack. A side plate perpendicular to the air inlet plate 2 and far from the two battery modules serves as the air outlet plate 3 of the battery box. An air outlet 11 is provided in the middle of the wind plate, an outlet fan 12 is provided inside the air outlet, and a deflector 13 is ...

Abstract

The invention relates to an improved cell box which comprises a box body and two cell modules that are arranged at the two opposite sides in the box body, wherein the box body consists of four side plates, a box cover and a box bottom, wherein the two side plates which are parallel to each other are taken as air inlet plates of the cell box, and another side plate which is vertical to the air inlet plates and is further away from the cell modules is taken as an air outlet plate of the cell box; each cell module comprises a battery pack, a baffle and a drainage plate, wherein the baffle is provided with a fan; the air inlet plates are provided with air inlets, and the air outlet plate of the cell box is provided with an air outlet which is provided with an outlet fan and the guide plates; and the guide plates are symmetrically arranged at the two sides of the fan. The cell box leads cold air to be absorbed into the box body through the air inlets by the fan and flow through gaps among batteries by the drainage plates, and the heat of the batteries can be taken away through the outlet fan at the air outlet, so that the structure leads the batteries to work in comparatively consistent environment, thus not only leading the batteries to be consistent and improving the safety when in use, but also prolonging the service life of the cell modules.

Description

technical field [0001] The invention belongs to the field of battery boxes, in particular to an improved battery box suitable for energy storage systems. Background technique [0002] As primary energy such as oil, natural gas and other resources become more and more scarce, human beings are faced with severe challenges that the living environment may continue to deteriorate. In order to reduce energy costs and realize the sustainable development of the world, countries all over the world have carried out research on energy storage technology, and the idea is to use large-capacity batteries as energy storage systems. Therefore, choosing a suitable battery has become one of the keys to the development of energy storage technology. [0003] At present, the batteries used in energy storage systems are mainly high-capacity lithium-ion batteries. Lithium-ion batteries have the advantages of high energy density, long life, no memory effect, and no pollution, and have been widely...
