Milvent Venting+Valve protects the battery pack
Milvent Venting+Valve protects the battery pack Allow release of excess pressure within the full EV battery pack enclosure With the development of electronic products and new energy vehicles, consumers have an increasing demand for power supply and energy storage, and have a higher and higher demand for environmental protection new energy products. Batteries gradually replace lead-acid batteries and are widely used in the fields of electronics, new energy vehicles and energy storage. New energy lithium battery is one of the most important core components of new energy vehicles Power lithium battery refers to the lithium battery applied in power drive system, such as automobile lithium battery, man-machine lithium battery, power tool lithium battery, geological exploration, environmental monitoring, automobile model, airplane model, self-balancing automobile lithium battery, etc.Compared with ordinary consumer lithium batteries, the requirements of power lithium batteries are generally more special, high energy density, high volume energy ratio, wide temperature range, support high rate of discharge, longer cycle life, more safe.This requires high reliability of the battery, which can adapt to various harsh external environments, such as different temperature and pressure changes. Milvent's new energy battery explosion-proof valve has three levels of protection for the battery: Stage 1: The passive venting function can balance the pressure inside and outside the battery pack product, while preventing the dust and water.  PIC 1. Curve changes under normal operation.
Stage 2: when the temperature in the battery pack rises rapidly and the pressure and heat accumulate rapidly, the explosion-proof valve is actively started and the valve is opened To discharge excessive pressure and protect the battery.  PIC 2. The internal curve changes when the battery heats up rapidly for a long time
Stage 3: When the pressure returns to normal, the valve of stage 2 will resume and close and be ready at any time.Active ventilation continues.  PIC 3. Rapid temperature rise of short time battery and normal internal curve changes.
Milvent's explosion-proof valve breaks through the design and improves the destruction-type design on the market. When the battery pack gets out of control and returns to normal in a short time, Mill's battery pack explosion-proof valve can be reused. From the practical application of the battery case is more complex, also may occasionally heats up quickly and then return to normal, not a momentary short more than normal pressure, the battery is not continue to use, as our mobile phone batteries, sometimes running program is overmuch, cause overload battery heating up too fast, but excess load program operation, mobile phone batteries will be back to normal, the temperature of the battery also can continue to use. Milvent's battery explosion-proof valve is designed to be reusable to protect the battery against complex and changing conditions. From the perspective of technology development, automotive power battery technology is the bottleneck technology that restricts the industrialization process of electric vehicles. With the industrialization of electric vehicles gradually thorough, and key enterprises are intensify efforts to the development of power battery industry, based on new materials and structure of the ratio can power battery technology has become a global focus and enhance the vehicle power battery safety, life, low temperature characteristics of lower cost is the direction of the industrial technology development.So it is very important to use the explosion-proof valve with high reliability. Currently Milvent battery pack venting with explosion-proof valves are available in both plastic and metal materials.Please feel free to consult us, we will provide professional services.
