Problems solved by technology

When the temperature is too low, its chemical activity decreases, resulting in a significant reduction in the effective capacity of the battery or even the inability to charge and discharge. In serious cases, it will also cause irreversible changes in the battery electrolyte and positive and negative electrode structures, seriously affecting battery life.
When the temperature is too high, although the battery activity is enhanced, the danger also follows
Charging and discharging at high temperature will cause the internal pressure of the battery to rise, and serious safety accidents such as battery explosion and fire will occur

Abstract

The present application discloses a battery box, which includes a box body and batteries sealed in the box body, the box body is arranged in double layers, and includes an inner wall and an outer wall made of fiber composite materials, and a gap between the inner wall and the outer wall A clamping space is formed, and a reflective layer and a heat insulating layer are formed in the clamping space, wherein the reflective layer is arranged close to the outer wall, and a heat generating layer is formed on the surface of the inner wall away from the clamping space. The box body of the present invention is integrally formed of composite materials, has the characteristics of firmness, light weight, heat preservation, waterproof and dustproof, flame retardant, etc., reduces the control cost of the external temperature control device, and saves energy consumption.

Description

technical field [0001] The application relates to a battery box with good thermal insulation effect, adjustable temperature inside the box and low control cost. Background technique [0002] In modern society, with the development of new battery technology, secondary batteries are used to store and provide energy in more and more fields. Especially in the energy storage of mobile devices, there are more and more applications, especially the demand for batteries in new energy vehicles is increasing. However, current secondary battery products are extremely sensitive to ambient temperature because the technical principle is electrochemical reaction. When the temperature is too low, its chemical activity decreases, resulting in a significant decrease in the effective capacity of the battery or even failure to charge and discharge. In severe cases, it will also cause irreversible changes in the battery electrolyte and positive and negative electrode structures, seriously affect...
