Improved cell box

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...

AI Technical Summary

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 the battery temperature is different, it will cause inconsistencies in the entire battery pack, thereby affecting the service life of the entire battery pack and leaving potential safety hazards.

In the existing battery box, the heat dissipation effect of the battery is poor, and it is difficult to ensure the consistency of the battery use conditions
