How to prevent car lithium battery from catching fire?

How to prevent lithium battery from fire Lithium battery test box Lithium battery fire test Lithium battery firepower test requires a strategic depth of multi-channel defense. In addition to using non-combustible or non-combustible data, as far as possible, the battery has a substantial safety performance. The first line of defense outside the battery is to prevent the battery from overheating and fire due to various reasons, such as overload, short circuit, collision, etc. This requires power system safety planning. When the first line of defense is broken (for example, the battery management system fails to cut off the charging power supply in time), the battery temperature rises, the temperature sensor or the gas or smoke detector monitoring system should promptly detect the fault and alarm, and prompt the staff to deal with the fault and eliminate it. The cause of the fire. This is the second line of defense. When the fault is not handled in time and the second preventing part is broken, the battery cannot be prevented from burning (smoldering). At this time, the fire control system should limit the combustion to the containment of the battery box (or box) in question, and isolate adjacent unfired batteries and equipment to prevent the fire from expanding. Since the temperature of the lithium battery after thermal control is very high, the existing non-aqueous resuscitation agents such as gas and dry powder cannot quickly reduce the battery temperature, and the effect of resuscitation is not very ambitious. Therefore, setting the battery fire strategy to controllable burnout is a practical method with strong technical and economic benefits. This is the third defense. When the fire control fails and the fire spreads and poses a serious threat to the safety of personnel and property, the fixed water-based resuscitation system in the car should be activated, or the fire brigade should make a resuscitation statement on the vehicle: Some pictures and content of the articles published on this site are from Internet, if there is any infringement, please contact to delete the previous article: Five meanings of using AGV lithium battery
