The invention discloses a multifunctional power battery state detection and display system, which are used for solving the problem that a set of non-battery-manufacturer power battery box fire early warning and alarming device is independently installed in the existing industry to be independently used and separated from a battery management system, the power battery box fire early warning and alarming device and the battery management system perform own duties which cause waste of resources and relatively high cost and the set alarm threshold value and the set alarm strategy are not always suitable for characteristics of batteries so that false alarm is generated; according to the invention, the detection slave control module with a fire detection function is integrated in the battery pack; the voltage, temperature, CO harmful gas, smoke and flame in the current battery pack are detected in real time and are transmitted to the detection main control module through the internal CAN line, and then are transmitted to the independent display screen through the external CAN line by the detection main control module, so that the related key information in the battery pack is displayed on the independent display screen in real time, the cost is low, the structure is simple, and the effect is remarkable.

    本发明公开了多功能动力电池状态检测及显示系统,用于解决现有目前行业内单独安装一套非电池厂家的动力电池箱火灾预警及报警装置,与电池管理系统分开独立使用,各司其职,造成资源浪费,成本相对较高以及设定的报警阀值、报警策略不一定十分适合电池自身的特性,会产生误报的现象的问题;本发明通过电池包内设有的集成带火灾探测功能的检测从控模块,实时检测当前电池包内的电压、温度、CO有害气体、烟雾和火焰,经过内部CAN线路传递到检测主控模块,再由检测主控模块通过外部CAN线路传递到独立显示屏中,使得电池包中的相关关键信息实时在独立显示屏上显示,成本低,结构简单,效果显著。
