Abstract

The invention discloses an airport all-electric drive fire fighting truck power lithium battery thermal disaster early warning system and method. The system comprises a power lithium battery, a monitoring system, an alarm system and a man-machine interaction system. The monitoring system is used for detecting a state of the power lithium battery and transmitting monitored data to a data acquisition system, the man-machine interaction system displays the data, and if a dangerous situation exists, people in the vehicle are informed through the alarm system. A voltage sensor, a temperature sensor, a strain pressure sensor, a combustible gas detector and a smoke detector are arranged in the power lithium battery. The power lithium battery of the system is monitored, data is transmitted to thedata acquisition system, and if preset conditions are met, the alarm system gives an alarm. The system and the method have advantages that accurate running states of a single lithium battery and the interior of a battery pack are provided in real time, and continuous, stable and safe running of the vehicle-mounted power lithium battery is guaranteed.

Description

technical field [0001] The invention relates to the technical field of fire early warning, in particular to a thermal disaster early warning system and method for an airport all-electric drive fire truck powered lithium battery. Background technique [0002] The airport's all-electric drive fire-fighting power lithium battery system has a capacity of 615Ah and a total power of 377.856Kwh. A total of 12 battery packs are included, and each battery contains 48 cells. Due to the special use environment of airport firefighting vehicles and the different temperature and pressure environments of airports in different regions, the vehicle-mounted power lithium battery system module also needs to withstand the use environment of wide temperature and wide pressure. Therefore, the research and development of the thermal disaster early warning module of the vehicle power lithium battery system under the condition of wide temperature field and wide pressure field is particularly import...
