The marketability of hybrid and electric vehicles depends largely on their power batteries. They must have high energy density, high performance and long service life, while also meeting strict safety standards. In electric vehicles, lithium-ion batteries currently dominate the field. In order to obtain the highest capacity and voltage, many lithium-ion batteries are connected together in the power battery. Therefore, the battery compartment in an electric vehicle is usually very large and weighs several hundred kilograms. For maximum safety, they are usually installed in a sealed enclosure under the seat on the bottom of the vehicle.

Therefore, when the vehicle encounters a puddle, car wash or fire, the battery of the high-voltage pool must be fully protected to prevent water from penetrating into the water body (for example, in difficult terrain or floods). Moisture can cause short circuits, compromising the safety and functionality of your safety vehicle.

In order to prevent batteries from exploding, batteries are now equipped with a safety valve on the top. The safety valve is standard for every battery and is also the most important explosion-proof barrier. When the internal pressure of the battery is too high, the safety valve on the top will open to exhaust and reduce pressure to avoid explosion.

The battery pack explosion-proof valve is a high-tech product designed and developed with a new concept. Through careful design, it integrates waterproof, breathable and explosion-proof functions. It not only has the functions of explosion-proof and reducing explosion damage of traditional explosion-proof valves, but also has waterproof and breathable functions. . It has high temperature resistance, non-burning, high impact resistance, high reliability, simple installation, high waterproof performance, large air permeability, high accuracy of detonation point, can be automatically reset after blasting and can be 100% inspected before shipment. Ensure product quality and other advantages.

When the pressure inside the battery pack reaches the explosion pressure value of the explosion-proof valve, it is directly connected to the outside and quickly deflates to prevent or reduce damage caused by the high pressure in the battery box during explosion. When the pressure inside the box is less than the burst pressure value, the pressure relief mechanism quickly resets and the product can continue to be used. Patented structural design, waterproof, breathable and explosion-proof performance can be 100% tested before leaving the factory to ensure product quality.
