Problems solved by technology

[0002] The source of fires in new energy vehicles is mostly caused by power battery problems. Although many new energy vehicles are designed with power battery fire prediction devices, safety accidents such as fires have occurred. The root cause of the problem is that the fire warning devices are only for batteries. Early warning of the problem. When the power battery overheats and other potential safety hazards, the vehicle is not controlled, and the vehicle can still drive the vehicle. When some drivers are negligent about the fault, serious consequences will be caused

Embodiment Construction

[0015] Below the present invention is further described:

[0016] see Figure 1-2 ,

[0017] The invention discloses a new energy vehicle fire early warning control strategy, including a fire early warning system. The fire early warning system includes a first-level early warning, a second-level early warning, and a third-level early warning, and the danger levels are divided into: first level, second level, and third level. Level, if there is a dangerous alarm, the vehicle controller will give corresponding alarm reminders and limit power for the vehicle. When the high-voltage battery temperature sensor detects that the temperature of the high-voltage battery module is greater than 75°C, it will be set as a first-level early warning. The high-voltage battery smoke sensor When smoke is detected or the temperature of the battery module is greater than 80°C, it is set as the second-level early warning; And the smoke sensor is installed at the installation position of the high-...

Abstract

The invention relates to the technical field of pure electric vehicle fire early warning system application, in particular to a new energy vehicle fire early warning control strategy, which comprisesa fire early warning system, and the fire early warning system comprises first-level early warning, second-level early warning and third-level early warning. Safety hazards caused by harmful gas leakage, smoke and fire hazards of high-temperature and high-voltage batteries in the running process of the vehicle can be avoided, battery fire early warning is divided into three levels, the whole vehicle is controlled according to the fire alarm level, a driver is reminded to conduct corresponding treatment, and the safety purpose is achieved.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a new energy vehicle fire early warning control strategy. Background technique [0002] The source of fires in new energy vehicles is mostly caused by power battery problems. Although many new energy vehicles are designed with power battery fire prediction devices, safety accidents such as fires have occurred. The root cause of the problem is that the fire warning devices are only for batteries. Early warning of the problem was carried out. When the power battery overheated and other safety hazards occurred, the vehicle was not controlled, and the vehicle could still drive as a whole vehicle. When some drivers were negligent about the fault, serious consequences would result. [0003] Based on the above reasons, the present invention proposes a new energy vehicle fire early warning control strategy, which divides the battery fire early warning into three levels, and t...
