Problems solved by technology

Among them, the air cooling occupies a large volume in the battery module, and the cooling effect of the air cooling is not ideal
The main reason is that the convective heat transfer coefficient on the surface of the battery is low and the heat transfer area is limited by the surface area of ​​the battery. In order for the air to take the heat out of the battery in time, the temperature of the battery must be raised, which affects the life of the battery and Charge retention is rather unfavorable

Abstract

The invention relates to a thermal management system for a battery pack. The thermal management system comprises the battery pack and a battery pack cooling device, wherein the battery pack comprises a plurality of single battery bodies; the battery pack cooling device comprises cooling fins and uniform temperature plates; the uniform temperature plates are arranged between the single battery bodies; and the cooling fins are arranged outside the single battery bodies. The thermal management system has the beneficial effects that the uniform temperature plates are arranged between the single battery bodies; and the cooling fins which are consistent with the single battery bodies are arranged on the outer surfaces of two sides of the uniform temperature plates, so that the cooling structure improves the cooling effect of batteries when utilizing existing module structure and battery pack volume; the battery temperatures are lowered from the level of an existing air-cooling module; the cost and the manufacturing time are saved; the structure is simple; and the manufacture procedure is simple and convenient.

Description

【Technical field】 [0001] The present application relates to the technical field of batteries, in particular to a thermal management system of a battery pack. 【Background technique】 [0002] With the increasing energy crisis and environmental pollution, pure electric vehicles and hybrid vehicles have emerged as the times require, and have increasingly become important means of transportation. The power battery is the energy carrier driven by pure electric vehicles and hybrid vehicles. In order to meet the requirements of fast charging and continuous mileage, as well as the kinetic energy of the vehicle under climbing, acceleration and other working conditions, the power battery must have high power output and large capacity. In order to ensure the high capacity and high power of the power battery, a large number of single power batteries are usually connected in series and parallel to form a battery module. During the fast charging and high-current discharging process of th...
