Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of test cabinets, in particular to an intelligent lithium battery fire protection test cabinet. Background Art
[0002] With the wide application of lithium batteries in various fields, such as electric vehicles, energy storage systems, portable electronic devices, etc., the safety issues of lithium batteries have become increasingly prominent. Since lithium batteries may undergo thermal runaway under abnormal conditions such as overcharging, short circuit, and high temperature, which may lead to fires or even explosions, it has become crucial to accurately and reliably test the fire protection performance of lithium batteries. Traditional fire protection test methods and equipment often have some limitations. For example, the tested parameters are not comprehensive enough to monitor multiple key indicators in real time and accurately; the degree of automation and intelligence during the test process is low, relying on manual operation and judgment, which is prone to errors and delays; it is difficult to effectively capture and warn of the subtle changes and potential risks in the early stage of a fire; moreover, some test equipment has insufficient performance and stability when dealing with complex fire scenarios. With the continuous development and progress of sensor technology, data analysis technology, automatic control technology, and computer simulation technology, it provides strong support for the research and development of intelligent lithium battery fire protection test cabinets. Advanced sensors can collect various parameters such as temperature, humidity, smoke, and combustible gas concentration in real time and accurately; powerful data processing and analysis capabilities can quickly process and judge these data to timely discover potential safety hazards; the automatic control system can automatically take corresponding protective measures according to preset conditions, such as starting the fire extinguishing device, cutting off the power supply, etc.; computer simulation technology can simulate and predict different fire scenarios before the test to optimize the test plan.
[0003] Most of the existing equipment only installs smoke alarms to detect whether a fire occurs, and the smoke alarms usually trigger an alarm after obvious smoke is generated in a fire. However, in the initial stage of a fire, especially some smoldering fires, a large amount of heat and toxic gases may be released before a large amount of smoke is generated. Relying solely on smoke alarms may lead to a response delay and miss the best fire extinguishing and rescue opportunities.
[0004] Therefore, there is an urgent need to provide an intelligent lithium battery fire protection test cabinet to solve the above problems. Summary of the Utility Model
[0005] The technical problem to be solved by the utility model is to overcome the above-mentioned disadvantages of the prior art and provide an intelligent lithium battery fire protection test cabinet.
