Description

Technical Field

[0001] The utility model relates to the technical field of vehicle fire extinguishing systems, in particular to a special automatic fire extinguisher for new energy vehicles. Background Technique

[0002] With the increasing global emphasis on environmental protection and sustainable development, electric vehicles have gradually become an important part of modern transportation due to their advantages such as zero emissions, low noise, and low maintenance costs. However, the widespread popularity of electric vehicles has also brought a series of new safety challenges. Among them, the main safety hazards come from the on-vehicle batteries and chargers of electric vehicles;

[0003] On-vehicle batteries, especially lithium-ion batteries, have advantages such as high energy density and long lifespan, but at the same time, there is a risk of thermal runaway. In abnormal situations such as overcharging, over-discharging, high temperature, or physical damage, safety problems such as short circuits and thermal runaway may occur inside the battery, thereby triggering a fire. In addition, the chargers of electric vehicles may also generate high temperature, electric arcs, or electric sparks under conditions such as long-term operation, overload, or electrical faults, thus triggering a fire;

[0004] If a fire breaks out during the charging of an electric vehicle, or if the battery shorts for any reason, the energy inside the battery will be released in the form of heat in a short time, which will ignite the internal components of the lithium battery, or cause the battery pack to rupture and the electrolyte to leak, thereby triggering the combustion or even explosion of the lithium battery in the vehicle. Since the internal structure of an electric vehicle is relatively enclosed, once a fire occurs, the fire is likely to spread rapidly and is difficult to be detected and extinguished in time. Therefore, it is necessary to detect the danger in time after the battery catches fire and extinguish the fire at the fastest speed to ensure personal and property safety;

[0005] Therefore, developing a fire extinguishing device that can be automatically triggered and quickly extinguish the fire source when a fire occurs in the on-vehicle battery or charger is crucial for improving the safety of electric vehicles. Content of the Utility Model
