Electric automobile fire active response and assisted self-rescue system based on novel battery box body

Abstract

The invention belongs to the technical field of pure electric automobile intelligent hardware and automobile services and relates to a power battery box body and an on-board fire active response and assisted self-rescue system based on an electric automobile. The on-board fire active response and assisted self-rescue system based on the electric automobile comprises a sensing layer, a decision layer and an execution layer; the sensing layer and the execution layer are both connected with the decision layer; the sensing layer transmits a sensor signal to the decision layer; the decision layer processes the sensor signal into a control signal through a microprocessor and transmits the sensor signal to the execution layer; the sensing layer comprises a temperature sensor, a smoke sensor, a flame sensor and a seat pressure sensor; the decision layer is a microprocessor formed by a single chip microcomputer; and the execution layer comprises a delay module, an alarm module, a GPS positioning module, an accident assisting module, an automobile cruise control system CCS and an indicator lamp module. According to different abnormal situations in a battery box, corresponding technical measures are adopted to limit an automobile speed and give a driver corresponding prompting; and therefore, a battery is protected, and humanized accident treatment services are provided for the driver.

Description

technical field [0001] The invention belongs to the technical field of pure electric vehicle intelligent hardware and vehicle service, and relates to an electric vehicle fire active response and auxiliary self-rescue system based on a novel battery box. Background technique [0002] With the increase in the use of electric vehicles in the market, fire accidents caused by lithium batteries have gradually increased, causing losses to people's lives and property. Electric vehicle fire accidents have gradually become the focus of media public opinion, such as an electric taxi Spontaneous combustion in the downtown area, an electric taxi collided and caught fire, and a city bus caught fire at a charging station have all aroused widespread concern from all walks of life. [0003] Most of the existing electric vehicle power battery fire prevention technologies are in the field of passive safety, that is, the design of flame retardant and fire prevention of power battery boxes or th...

Problems solved by technology

[0004] However, the fire situation of the power battery is complicated, and the power battery is in a state of thermal runaway after the fire. The existing technology may not be able to guarantee the effective control of the flame and the accurate and timely fire extinguishing treatment, so the active response to the fire of the power battery seems to be especially important

[0005] The existing protection measures for electric vehicle power batteries are to add detection components or fire extinguishing components in the battery box, sacrificing part of the space of the battery box, which also limits the number of batteries arranged; the existing protection for the battery box The equipment has many holes on the surface of the box, which affects the sealing of the battery, which is not conducive to the waterproof, moisture-proof, and impact-proof of the battery; the existing battery fire prevention technology is mostly in the field of passive safety, and it is to take corresponding measures after the battery catches fire. measures to protect the personal safety of drivers and passengers, and it cannot completely and effectively control the fire, and it lacks corresponding auxiliary self-rescue measures after the fire
