MDR-3120 电池热失控烟雾传感器

        电池热失控烟雾传感器能够实现对电芯热失控时释放出的粉尘浓度、温度等指标的有效监测，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粉尘浓度、温度的监测和预警作用。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。
        The battery thermal runaway smoke sensor CAN effectively monitor the dust concentration and temperature released when the battery cell is thermal runaway, and transmit the measurement signal to the battery management system (BMS) through the CAN bus, so as to play a role in monitoring and warning the concentration and temperature of the thermal runaway dust in the battery cell. 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.
