Problems solved by technology

[0003] There are two heat dissipation methods for the battery box in the prior art: one is to induce the natural wind outside the car to dissipate heat. The disadvantage of this method is that when the air temperature outside the car is too high, the natural wind outside the car will not be able to dissipate heat. effect; the other is to independently lead the air-conditioning wind i

Abstract

The invention discloses a heat radiating method and mechanism of an electric automobile battery box. The heat radiating method comprises the following steps: introducing natural air outside an automobile to radiate heat when the temperature in the battery box exceeds the preset temperature T2; radiating heat by extracting air-conditioning cold air in the automobile when the temperature in the battery box exceeds the preset temperature T4, wherein T4>T2; and stopping extracting the air-conditioning cold air in the automobile when the air-conditioning cold air is subjected to heat radiation, so that the temperature decreases and does not exceed the preset temperature T3 which is lower than T4 and higher than T2, and introducing natural air outside the automobile to radiate heat. The heat radiation method can play a better heat radiation effect on the battery box, does not waste energy, and meanwhile does not affect the environment in the automobile.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a heat dissipation method and a heat dissipation mechanism for a battery box of an electric vehicle. Background technique [0002] With the shortage of oil resources and the enhancement of people's awareness of environmental protection, electric vehicles have gradually entered people's field of vision. As the main energy storage unit of electric vehicles and the power source for driving vehicles, the battery pack is a key component of electric vehicles, and its working status directly affects the performance of electric vehicles. Lithium-ion batteries have good power output characteristics and long life advantages, so they have been widely used in electric vehicle battery packs. However, lithium-ion batteries are very sensitive to temperature changes, especially those used in existing electric vehicles are large-capacity, high-power lithium-ion batteries, which have a ...
