Battery pack exhaust structure

Abstract

The invention discloses a battery pack exhaust structure which comprises a battery pack and an exhaust assembly, wherein the battery pack is fixed on the vehicle body on the back side of a back row seat; the exhaust assembly comprises a first connecting pipe, a three-way joint, a four-way joint, a second connecting pipe and a mounting joint; the battery pack and the exhaust assembly are connected by virtue of the first connecting pipe; the three-way joint is arranged at the tail end of the exhaust assembly; the joints in two ends of the three-way joint in the transverse direction are respectively connected with the battery pack; the four-way joint is arranged in the middle of the exhaust assembly; the joints in two ends of the four-way joint in the transverse direction are respectively connected with the battery pack; two ends of the second connecting pipe are respectively connected with the three-way joint and the four-way joint; the mounting joint is arranged at the forefront end of the exhaust assembly and is fixedly connected with the battery pack; and one end of the mounting joint is connected with the four-way joint, and the other end of the mounting joint is connected with an exhaust guide pipe on the vehicle body. According to the battery pack exhaust structure disclosed by the invention, the exhaust assembly is arranged outside the battery pack, and gases produced by a chemical reaction of the battery are discharged out of the vehicle by virtue of the exhaust assembly, so that the service stability and safety of the battery of an electric vehicle are improved.

Description

Problems solved by technology

[0005] The purpose of the present invention is to provide a battery pack exhaust structure. By setting the exhaust assembly outside the battery pack and using the cooperation between the exhaust assembly and the battery pack, the original open thermal management system is not safe and easy to solve. The problem of introducing toxic gas into the car, or the gas leaked from the battery in the closed thermal management system is not easy to discharge, and the problem of battery explosion caused by the excessive pressure difference between the inside and outside of the battery pack can effectively improve the stability and safety of the battery pack.
