Auxiliary fire fighting device for test of power battery for vehicle

Abstract

The invention provides an auxiliary fire fighting device for a test of a power battery for a vehicle. The auxiliary fire fighting device comprises a testing table, a detecting table, an anti-explosioncover, an oil cylinder and a vacuum pump. The testing table is provided with the detecting table for storing a to-be-tested sample, the anti-explosion cover is arranged over the testing table, and the oil cylinder is connected with the anti-explosion cover and drives the anti-explosion cover to vertically move. The vacuum pump for pumping air in the anti-explosion cover is arranged at the top ofthe anti-explosion cover, a temperature sensor and a pressure sensor are arranged in the anti-explosion cover, and a travel switch is arranged on the side wall of the anti-explosion cover. The auxiliary fire fighting device for the test can be well applied to the situation that failure reactions occur in the testing processes of battery single bodies and modules, rapid reacting can be conducted, the safe and environment-friendly effects are achieved, burning failed samples can be efficiently protected in time, analysis and research on the samples in the later period are facilitated, and sufficient technology and data support can be provided for engineering research and development tests and product verification of relevant departments, drafting and amending of standard laws and rules, andthe like.

Description

technical field [0001] The invention belongs to the field of new energy vehicle testing, and in particular relates to an auxiliary fire extinguishing device for vehicle power battery testing. Background technique [0002] In recent years, the global electric vehicle market is growing at a faster rate, and the production and sales of electric vehicles have increased significantly. This mainly depends on the successive release of electric vehicle development strategies and national plans by governments of various countries, which further pointed out the direction for industrial development; the second is Power batteries have been highly valued, R & D investment has increased sharply, and the expectation of breakthroughs in electric vehicle technology bottlenecks has been greatly enhanced; third, governments of various countries have increased policy support and fully promoted the industrialization of electric vehicles; fourth, pure electric vehicles have benefited from high-per...

AI Technical Summary

Problems solved by technology

[0005]At present, in the electric vehicle power battery testing organization, the treatment after the battery catches fire and explodes during the test generally adopts sand burying, water spraying, and carbon dioxide fire extinguisher to extinguish the fire Wait, but in the application process, the above treatment methods have many defects, such as pollution problems in the fire extinguishing process, which may easily cause safety risks to the test equipment, cannot save the shape of the sample after failure, and is not conducive to the analysis and research of the sample in the later stage, etc.
