MDR-3131 储能电池热失控(PM+CO2+H2)监测传感器

        储能电池热失控(PM+CO2+H2)监测传感器能够实现对电芯热失控时释放出的颗粒物浓度、CO2、H2等指标的有效监测，并将测量信号通过CAN总线传递给电池管理系统（BMS），从而起到电芯热失控颗粒物浓度、CO2、CO的监测和预警作用。当电芯发生热失控时，传感器能够迅速检测到气体压力的变化，并通过CAN总线将这些信息实时传递给BMS。BMS接收到信号后，能够及时采取相应的措施，如触发预警机制或启动安全策略，以防止热失控进一步扩散，保障电池系统的安全。
        Energy storage battery thermal runaway (PM+CO2+H2) monitoring sensor CAN effectively monitor the particle concentration, CO2, H2 and other indicators released when the battery is thermal runaway, and transmit the measurement signal to the battery management system (BMS) through the CAN bus, so as to play a monitoring and warning role in the concentration of thermal runaway particles, CO2, CO. When thermal runaway occurs in the cell, the sensor CAN quickly detect the change in gas pressure and transmit this information to the BMS in real time through the CAN bus. After receiving the signal, the BMS can take appropriate measures in time, such as triggering the early warning mechanism or initiating the safety policy, to prevent the further spread of thermal runaway and ensure the safety of the battery system.
