Problems solved by technology

[0002] When the battery pack is short-circuited, overcharged, over-discharged, or subjected to collisions and other safety accidents, the battery management system may issue a warning and cut off the abnormal circuit, but it cannot prevent thermal runaway and thermal diffusion
At the same time, due to the impact of size and technology, there is currently no good protection method inside the battery pack. For example, there are certain false alarms or non-reporting situations in smoke alarms. rescue
When the fire officers and soldiers arrived at the scene of the accident, they could only extinguish the external flames. The batteries inside the battery pack continued to explode and catch fire, threatening personal and property safety.

Abstract

The invention discloses a battery pack and an electric automobile provided with the battery pack. The battery pack comprises a battery box, a battery closed inside the battery box, and a water coolingsystem used for absorbing the heat of the battery; the water cooling system comprises a circulating water channel filled with cooling water; and the water cooling system also comprises a water inlethole, a water diversion pipe and a waterproof breathable film, wherein the water inlet hole is formed in the box wall of the battery box in a cut-through manner, one end of the water diversion pipe isconnected with the water inlet hole in a sealing manner and the other end of the water division pipe is connected with the circulating water channel of the water cooling system in the sealing manner,and the waterproof breathable film is used for sealing and blocking a water channel formed by the water division pipe and the water inlet hole together. When thermal runaway occurs on the battery inside the battery pack, the internal voltage of the battery pack can be released quickly, and the explosive power is reduced; and simultaneously, the heat inside the battery pack is absorbed rapidly, sothat thermal diffusion is reduced.

Description

technical field [0001] The present application relates to the field of batteries, in particular to a battery pack and an electric vehicle equipped with the battery pack. Background technique [0002] When the battery pack is short-circuited, overcharged, over-discharged, or subjected to collisions and other safety accidents, the battery management system may issue a warning and cut off the abnormal circuit, but it cannot prevent thermal runaway and heat spread. At the same time, due to the impact of size and technology, there is currently no good protection method inside the battery pack. For example, there are certain false alarms or non-reporting situations in smoke alarms. rescue. When the fire officers and soldiers arrived at the scene of the accident, they could only extinguish the external flames. The batteries inside the battery pack continued to explode and catch fire, threatening personal and property safety. Contents of the invention [0003] The purpose of thi...
