Thermal disaster warning system and method for power lithium battery of airport all-electric drive fire truck

Abstract

The invention discloses a thermal disaster warning system and method for a power lithium battery of an airport all-electric drive fire truck, comprising: a power lithium battery, a monitoring system, an alarm system, and a human-computer interaction system; the monitoring system is used to detect the state of the power lithium battery, And the monitored data is transmitted to the data acquisition system and the human-computer interaction system for data display. If there is any danger, the personnel in the vehicle will be notified through the alarm system. The power lithium battery is equipped with voltage sensors, temperature sensors, strain pressure sensors, flammable gas detectors and smoke detectors; the power lithium battery of the monitoring system and transmits data to the data acquisition system. If the preset conditions are met, then The alarm system provides an alarm, and the invention has the advantages of providing accurate operating status of the single lithium battery and the internal operation state of the battery pack in real time, so as to ensure the continuous, stable and safe operation of the vehicle-mounted power lithium battery.

Description

Technical field [0001] The present invention relates to the field of fire early warning technology, particularly to an airport all-electric drive fire truck power lithium battery thermal disaster early warning system and method. Background [0002] The airport all-electric drive fire power lithium battery system has a capacity of 615Ah and a total power of 377.856Kwh. A total of 12 battery packs are included, each containing 48 monomers. The special use environment of airport fire fighting vehicles and the different temperature and pressure environments of airports in different areas, the vehicle power lithium battery system module needs to withstand a wide temperature and wide pressure environment at the same time. Therefore, the research and development of the thermal disaster early warning module of the vehicle-powered lithium battery system under the condition of wide temperature field and wide pressure field is particularly important. The high-speed start and stop of the fir...
