Problems solved by technology
However, on the one hand, its fire alarm forecast cannot comprehensively analyze the actual operation of the batteries in the battery compartment, resulting in low fire alarm forecast accuracy; on the other hand, this technical solution only detects the temperature and smoke of the battery compartment environment, and cannot The actual abnormal situation inside the battery occurs in time, so it has a large lag, which is not conducive to timely detection of fire, resulting in missing the best rescue opportunity
[0005] The utility model patent with the authorized announcement number CN 205549285 U discloses an intelligent fire warning and automatic fire extinguishing device for the vehicle engine compartment or power battery compartment. An alarm is issued for abnormal temperature or smoke that has occurred, and there are also problems such as low forecast accuracy and strong forecast lag

The invention discloses a composite battery fire warning system. The composite battery fire warning system comprises a first temperature monitoring unit, a smoke monitoring unit, a second temperature monitoring unit, a chemical component monitoring unit, a power monitoring unit and a control unit, wherein the control unit is in communication connection with each monitoring unit for receiving monitoring data, and a monitoring dispatching signal and / or fire warning signal is generated according to the received monitored data and preset data. The system can be used for accurately and timely acquiring a running parameter in a battery, the monitoring dispatching signal can be adjusted and improved in real time by rapid and integrated analysis, so that the reliability of the system is further improved, and energy consumption is reduced.
Description
technical field [0001] The invention relates to the technical field of battery fire alarms, in particular to a composite battery fire alarm system. Background technique [0002] The power battery is the power source that provides the power source for the tool, and mostly refers to the battery that provides power for electric vehicles, electric trains, electric bicycles, and golf carts. It is mainly different from the starter battery used to start the car engine. As the core component of electric vehicles, the safe operation of power batteries is the basis for the safe operation of various equipment. [0003] At present, the power equipment of new energy buses is mainly power batteries or super capacitors, and a new energy bus is generally installed with multiple battery boxes, and a large number of power battery units or super capacitors are installed in the battery boxes. When short-circuit thermal runaway, high temperature, external force extrusion, puncture, etc. occur ...
