Problems solved by technology

[0003] Thermal runaway is an important problem that threatens the safety performance of battery products. In traditional battery packs, fireproof cotton is generally covered on the upper part of the battery pack to temporarily slow down the heat spread during thermal runaway. Although this method can play a certain protective role , but there is a problem of poor gas circulation, so that the gas and flames and other fluids generated during thermal runaway will damage the battery pack because they cannot be discharged in time, and even cause safety accidents

Abstract

The invention relates to the technical field of batteries, in particular to a battery pack and a vehicle. The battery pack provided by the present invention includes a first separator, a battery row and a protective member, the first separator is located between two adjacent batteries in the battery row along the first direction, and the upper surface of the first separator is lower On the upper surface of the top cover, a recess is formed between the battery row and the first separator. The protective member includes a first protective part and a second protective part. The first protective part covers all explosion-proof valves of the battery row and is connected to the upper surface of the battery row. There is a channel between them, the channel is used to guide the fluid to flow along the first direction and has a downward opening, and the second guard part closes the part of the opening facing the concave part. By arranging the second protection part to seal the part of the downward opening of the channel facing the recess, the present invention can effectively prevent the fluid generated by thermal runaway from flowing into the recess, more reliably realize the directional discharge of the thermal runaway fluid, and improve the battery pack safety performance.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a battery pack and a vehicle. Background technique [0002] With the vigorous development of new energy vehicles, the demand for power battery products is increasing, and the safety performance of battery products is getting more and more attention. [0003] Thermal runaway is an important problem that threatens the safety performance of battery products. In traditional battery packs, fireproof cotton is generally covered on the upper part of the battery pack to temporarily slow down the heat spread during thermal runaway. Although this method can play a certain protective role , but there is a problem of poor gas circulation, so that fluids such as gas and flames generated during thermal runaway will damage the battery pack and even cause safety accidents because they cannot be discharged in time. Contents of the invention [0004] A technical problem to be solved by the pr...
