The invention discloses a power-off protection system and method for vehicle driving, and belongs to the technical field of power-off protection systems.A central processing unit obtains temperature change establishing curve change state monitoring data, gas concentration establishing curve change state monitoring and a flame analysis module judges whether flames or flickering sparks exist or not; when the temperature is suddenly changed, spark data of flame or flickering judged by the flame analysis module is synchronously obtained for verification, if the spark data is verified, it is determined that the thermal runaway state is not the fire state, and the information is fed back to the alarm module for cooling treatment; and if the spark data is verified, it is determined that air is not circulated and gas generated by materials around the battery at high temperature is gathered, ventilation and cooling treatment is carried out, and the flame analysis module is used for determining that the flame is the flame.
本发明公开了一种车辆行驶的断电保护系统及方法,属于断电保护系统技术领域,中央处理器获取温度变化建立曲线变化状态监测数据、气体浓度建立曲线变化状态监测和火焰分析模块判定为火焰还是闪烁的火花后进行判定,当获取温度突变时,并同步获取火焰分析模块判定为火焰还是闪烁的火花数据进行核实,核实为火花数据则认定为热失控状态并非失火状态,则将该信息反馈至警报模块进行降温处理,当获取浓度突变时,并同步获取火焰分析模块判定为火焰还是闪烁的火花数据进行核实,核实为火花数据则认定为空气不流通且在高温下电池周围的材质产生的气体聚集导致,则进行通风和降温处理,取火焰分析模块判定为火焰。
