Milvent M20X1.5 Breather with valve product for battery pack application

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...

This curve simulates an environment with a rise of 50°C within 50 minutes. It simulates the situation of starting a car on high speed in cold weather. Under the condition of airtight, the internal pressure will reach about 18KPA. With Milvent's battery pack vents with explosion-proof valve, the differential pressure can be quickly reduced to less than 1kPa 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...

This curve simulates rapid temperature rise for a long time in the case of out-of-control battery heat, and the pressure exceeds the pressure tolerated by the battery pack shell by 150kpa. The battery pack will burst if the battery pack is not vented quickly. Milvent battery pack explosion-proof valve is fit for above application, and the internal design has the function of active ventilation + passive ventilation valve. In the case that the passive ventilation cannot meet the requirements of ventilation, the active ventilation valve can be opened to provide additional pressure for exhaust.It...

This curve simulates the situation of rapid temperature rise in a short time under the condition of out-of-control battery heat, pressure exceeding 150kPa tolerated by battery pack housing, and then resuming normal operation. Milvent battery pack explosion-proof valve is fit for above application, and the internal design has the function of active air vent valve, which can be reused: it can be opened and then closed as the battery pack pressure returns to normal, to continue the next repetition work. Milvent's explosion-proof valve breaks through the design and improves the destruction-type design...
