Battery box with excellent performance of ventilation and heat dispersion

Abstract

The invention relates to a battery box with the excellent performance of ventilation and heat dispersion. The battery box comprises a box and a battery pack arranged in the box, wherein the battery pack is fixed in the box through splints arranged on both sides of the battery pack; angle steel I for fixing the battery pack is connected between the two splints; gaps are reserved among batteries forming the battery pack; two lateral plates, which are perpendicular to a plane where the gaps are positioned, of the box are respectively an air inlet plate and an air outlet plate; an air inlet is formed on the air inlet plate, and an exhaust fan is arranged on the air outlet plate; drainage plates are arranged on the lateral surface, which is opposite to the air inlet plate, of the battery pack; and gaps among the drainage plates correspond to the gaps among the batteries. In the battery box, cold air is inhaled to the box from the air inlet through the exhaust fan, and flows through the gaps among the batteries through the drainage plates to take heat generated by the battery pack away. Through the structure, the batteries can operate under the consistent environment, so that the batteries are consistent, the safety of the battery pack during use is improved, and the service life of the battery pack is also prolonged.

Description

technical field [0001] The invention belongs to the field of battery boxes, in particular to a battery box suitable for energy storage systems with good ventilation and heat dissipation. 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 n...

AI Technical Summary

Problems solved by technology

Lithium-ion batteries are greatly affected by temperature. When the battery temperature is different, it will cause inconsistencies in the whole box of batteries, which will affect the service life of the whole battery pack and leave a safety hazard.

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
