Embodiment Construction

[0033] The present invention aims to provide a solution for rapid cooling of the vehicle power battery pack when it fails. Specifically, the present invention provides a cooling system for a vehicle power battery pack. Please refer to figure 1 , the system includes: a power battery pack 1 , a spout 2 , a coolant storage device 3 , a power battery pack casing 4 and a coolant pipeline 5 . The power battery pack casing 4 is used to accommodate the power battery pack 1 , and the coolant pipeline 5 is used to connect the coolant storage device 3 and the nozzle 2 .

[0034] The present invention is designed to use the liquid stored in the coolant storage device 3 in the vehicle to cool the faulty power battery pack 1 when the power battery pack fails, reducing the risk of burning, explosion and other dangers. Specifically, a nozzle 2 is opened on the vehicle coolant pipeline 5 , and the nozzle 2 is located in the casing 4 of the power battery pack and faces the surface of the powe...

Abstract

The invention provides a cooling system of a power battery pack for a vehicle. The power battery pack comprises a power battery pack casing in which the power battery pack is positioned. The cooling system comprises a cooling liquid storing device, at least one nozzle and a cooling liquid pipeline which is used for connecting the cooling liquid storing device with the nozzle, wherein the nozzle is positioned in the power battery pack casing, faces the surface of the power battery pack and is started when a failure assessment parameter of the power battery pack meets a preset starting condition, so that a liquid in the cooling liquid storing device can be sprayed to the power battery pack. As the cooling system is used, a large amount of heat is adsorbed via liquid gasification, so that the power battery pack in failure can be cooled. Thus, the safety of the vehicle is ensured.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a cooling system for a vehicle power battery pack. Background technique [0002] With the rapid development of the world economy, the penetration rate of automobiles is constantly rising, and the pollution of automobile exhaust to the environment is also becoming more and more serious. As a daily means of transportation, the energy-saving and emission-reducing performance of automobiles is particularly important. More environmentally friendly hybrid vehicles and "zero-emission" electric vehicles have become the future development trend of automobiles. [0003] For hybrid vehicles and electric vehicles, the battery pack has extremely high energy. If the power battery pack fails, it is very likely to cause excessive temperature. Excessive temperature may not only ignite the battery pack casing, but also easily cause the battery to burn. Internal combustion, explosion, endanger p...
