Fire safety control system for high-pressure hydrogen storage of new energy vehicles

Abstract

The invention provides a fire safety control system for a high-pressure hydrogen storage system of a new energy vehicle, belongs to the electromechanical technical field, and solves the problem that staff escape safety under a fire environment in the prior art is relatively poor. The system is arranged in a vehicle body of the new energy vehicle, and comprises a controllable steering pressure relief device, a steering drive part, environment induction equipment and an alarm, wherein the controllable steering pressure relief device comprises a hot-melting pressure relief valve, a guide tube anda steering tube; the steering device part is a servo motor; the environment induction equipment comprises a sensor I for detecting whether people is in the vehicle or not, a sensor II for detecting whether staff or the vehicle is on the rear part of the vehicle body or not, a sensor III for detecting the environment temperature of a gas storage bottleneck, and an alarm. The system realizes recognizing according to the environmental condition to control pressure relief and direction in a self-adaptive mode, raises the alarm to pre-alarm, solves the safety escape problem, under the fire environment, of a driver, passengers and personnel outside the vehicle, and remarkably reduces fire risk level of a high-pressure hydrogen storage system of the new energy vehicle.

Description

technical field [0001] The invention belongs to the field of electromechanical technology, and relates to a fire safety control system for high-voltage hydrogen storage of new energy vehicles. Background technique [0002] New energy vehicles are a strategic emerging industry that my country focuses on supporting and developing. Among them, hydrogen fuel cell vehicles have a good development momentum due to their significant advantages such as high energy efficiency and zero emissions. my country's "Thirteenth Five-Year Plan for the Development of Strategic Emerging Industries" proposes to achieve mass production and large-scale demonstration applications of fuel cell vehicles by 2020. However, safety issues are one of the obstacles hindering the promotion of hydrogen fuel cell vehicles. High-pressure hydrogen storage, easy leakage, flammability and explosive properties make vehicle-mounted high-pressure hydrogen a source of danger, and different types of accident conseque...

[0005] Although TPRD has avoided the catastrophic explosion of hydrogen storage bottles, the side effects of TPRD opening cannot be ignored

The Japan Automotive Research Institute conducted a TPRD leak experiment and showed that after opening downwards, the hydrogen flame will surround the entire body, making it difficult for the driver and passengers to escape safely.
