Milvent Battery Pack Vents Simulation Testing Report - 1

Milvent Vent with Valve protects the battery pack Simulation Testing for different conditions. 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 Battery Pack Vents Simulation Testing Report - 2

Milvent's Vent with valve has three Stages 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. 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. (Battery Pack Size: LxWxH=2148x1444x355mm).Battery Pack Housing material is Aluminum. With Milvent's...

Stage 2: when the temperature in the battery pack rises rapidly and the pressure and heat accumulate rapidly, the Vent with 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 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...

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. 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 Vent with valve is fit for above application, and the internal design has the function of active air vent valve, which...
