Active air-cooling heat dissipation battery box for hybrid electric vehicle

Abstract

The invention discloses an active air-cooling heat dissipation battery box for a hybrid electric vehicle. The active air-cooling heat dissipation battery box comprises a battery box, wherein the battery box is of a trapezoid structure; two round air inlets which are distributed on the left and right are arranged in the top part of the battery box; rectangular air outlets which are distributed on the left and right are arranged in the bottom part; battery packs arranged in a fan shape are arranged in the battery box; a temperature monitoring and early warning module is arranged at the left side in the battery box; heat dissipation air flues are arranged between the longitudinally arranged battery packs; temperature sensors are arranged in the battery packs at eight corners of the battery box respectively; and a heat dissipation fan and ventilating dustproof and waterproof cotton are arranged in each air inlet. The active air-cooling heat dissipation battery box has the advantages that, with an automatic control technology as a core, a virtual instrument technology, a sensor technology and an electrical control technology are integrated; and efficient use of a battery box heat dissipation system for the hybrid electric vehicle is achieved, so that the battery box heat dissipation system is safer, more reliable and more efficient.

Description

Technical field [0001] The invention relates to the technical application field of electric vehicle batteries, in particular to an active air-cooled heat dissipation battery box for hybrid vehicles. Background technique [0002] With the deterioration of the environment and the increasingly serious energy shortage, electric vehicles are the focus of future research and development in the automotive industry. The improvement of battery pack performance is a key research aspect of improving the performance of electric vehicles. [0003] The battery pack emits a lot of heat during operation, and this heat cannot be quickly and effectively dissipated, which will cause the performance of the battery pack to decline, and seriously cause the battery to burn and explode. [0004] The existing air-cooled heat dissipation system takes the surface temperature of the battery as the control object, and ignores the heat transfer process of the temperature from the inside of the battery to the out...

AI Technical Summary

Problems solved by technology

[0003] The battery pack will emit a lot of heat during operation. If the heat cannot be dissipated quickly and effectively, it will lead to a decline in the performance of the battery pack, and it will seriously cause the battery to burn and explode.

[0004] The existing air-cooled heat dissipation system takes the surface temperature of the battery as the control object, and ignores the heat transfer process from the inside of the battery to the outside of the battery, that is, the asynchrony between the internal temperature of the battery and the surface temperature of the battery, and there is a heat dissipation lag phenomenon.

Moreover, the existing cooling fans are basically driven by constant power or in different stages for heat dissipation, which has problems such as low energy utilization rate and peak heat cannot be dissipated in a timely and effective manner.
