DGBELL is one of the largest manufacturers of environmental test chambers worldwide. First I will go over a few key terms associated with reliability testing. Design validation, products. Validation, environmental stress screening, and product lifecycle testing are four of the most popular tests used for environmental testing.

 

Common Specifications of Environmental Testing

The procedure is called an aggravated cycle. The cycle begins with 95% relative humidity at 30 degrees Celsius. Then it heats up to 60 degrees celsius. The temperature stays at 60 degrees Celsius for six hours. 

Next, we cool down to thirty degrees celsius and so get that temperature for four hours. After that, we turn the product on and allow it to soak at the same temperature for another four hours. Notice that we maintain a 95 percent relative humidity throughout the entire cycle. After this first cycle is complete 24 hours total it is ready to be repeated.

 

The layout of a Typical Environmental Test chamber

We’ll go over the environmental test chamber on the left starting clockwise with the serial communications panel you’ll find the control system. Right above it next on the top right is where chamber pressures are released. Through the exhaust port is an entry port that allows wires and thermocouples to be placed on the product under test and connected to an external data acquisition device. Lastly, casters allow for easy chamber maneuvering turning to the chamber on the right.

Let’s start from the top now looking to the inside of the chamber. You will see two lights are allowing visual access to the inside of the environmental test chamber. You will find the moveable product temperature control thermocouple, an electronic to humidity sensor, and an air baffle that supplies the air over the product under test. 

The control thermocouple is also located on the ceiling; the white arrows represent the airflow as it is directly distributed over the product and the air returns from the chamber floor. The humidity system is located on the right side cabinet and the compressors and condensers are housed in the front cabinet now.

 

Definitions of Components Used Inside Test Chamber

• Thermocouple

A thermocouple is a movable device that measures temperature product temperature control maximizes stress on the product through the chambers.

 

• Temperature Control Vs. Airstream Control

Control system and optimized airflow air stream control measure the air temperature at the outlet source of the air supply. Product temperature control measures the product’s temperature.

 

• Cascade Vs. Single Stage Refrigeration

Cascade refrigeration systems consist of two compressors that allow the chamber to go to minus 70 degrees Celsius single-stage refrigeration consists of one compressor that allows the chamber to typically go to minus 40 degrees Celsius.

 

• Air Cooled Vs. Water Cooled Condenser

The environmental test chamber’s refrigeration system can be cooled in one of three ways. Chambers with six horsepower compressors are smaller and can be cooled with onboard air or a water-cooled condenser. 

Chambers with six horsepower compressors or larger can be cooled with either water-cooled or remote air-cooled condensers. Remote air-cooled condensers are typically placed outside either on top of the facility or the ground. The purpose of all condensers is to draw the heat away from the compressors and other refrigeration system components.

 

• Dry Air Purge or Gaseous Nitrogen Purge

The dry air purge alternative empowers reduced moisture functioning at low temperatures. The machine is made up of a flow meter controller and regulator solenoid complete application. It uses compressed air as the source and is extremely useful in reducing moisture from the room. Gaseous nitrogen is another alternative to dry air purge; it aims to reduce the environmental test chamber’s moisture level.

 

• Liquid nitrogen boost with an oxygen monitor

Liquid nitrogen boost enables faster pull-downs and dissipation of heat from the product. An oxygen monitor or monitors can be added to the chamber or test lab to monitor oxygen levels. It also features an alarm if a depleted oxygen environment exists.

 

• Electronic Humidity Sensor Vs. Wet-bulb

Basic humidity systems have a few components. An electronic humidity sensor gives high-quality responses and is very accurate at low humidity levels. It does not require as much maintenance as a wet-bulb dry bulb system, which may require frequent wick replacements and a humidity system that can be clogged with dirty water from the test.

 

• Steam Generator Vs.Water Bath

The steam generator produces high volumes of moisture and water vapor consistency which is good for transitions. The water bath system can’t generate high volumes of moisture and has poor low humidity control due to the water in the bath. 

 

Benefits of Environmental Testing and Test Chambers for Industries

It’s necessary to check products for reliability before releasing components into manufacturing, ensuring that products may reliably withstand different environmental problems. It’ll reduce costs related to recalls and warranties. Item testing may also provide you a competitive edge since it aids in designing and producing a more robust product. So the item is prepared for consumer use. 

Reliability testing also helps customers meet supplier prerequisites. The most typical forms of environmental testing comprise humidity and temperature. This guide is going to concentrate on other common kinds of testing, including elevation and vibration tests.

 

• Design validation Testing

Product design is validated to ensure the basic functionality remains smooth in the normal environment. It will encounter during its life cycle in a specification driven and can be done in the R&D phase. During the production phase, the goal is to pass the test and meet the specification without any failures and the result is a robust product.

 

• Product Validation

The purpose of product validation is to ensure that the product meets the requirements specifications and regulations for which it is intended. The product validation procedure uses simulations similar to those of design validation to foresee faults or gaps in the design or manufacturing stages that might cause failures.

 

• Environmental Stress Screening

When customers utilize the merchandise, environmental stress screening employs an assortment of unique stresses like thermal cycling to induce latent defects. In recently manufactured or repaired products or components (usually digital), the potential for failure means catastrophic consequences. The living components or products are supposed to have more excellent reliability compared to a comparable unscreened population.

 

• Product Lifecycle Testing

You will find producers for these four kinds of evaluations by simulating real field surroundings such as humidity and temperature. Many products undergo conventional testing processes, which are frequently accepted by the army, IEC, UL. 

A few significant markets environmental test chambers and make a profit from product reliability testing. The markets do testing for the protection of their products such as aerospace, consumer electronics, automotive, etc. Any electronics Will requires testing to make sure it will correctly work in virtually any climate and experiences.

 

 

 

Usually, lithium-ion batteries are among the safest forms to use. However, if they’re damaged or include defects, they may be dangerous for employees who control material handling equipment. Whenever you’re on the market for a brand-new lithium-ion battery provider, UL 2580 battery safety test certificates are a must-have. The meticulous testing and product requirements help make sure you’re not carrying a risk, and the certification procedure helps producers ascertain their upkeep and care instructions. The UL 2580 Listed certificates are to different criteria based on the battery’s character regarding lithium-ion batteries.

UL 2580, by way of instance, supplies safety-related certificates, validation, testing, review, auditing, counseling, and training solutions to a broad array of customers, including manufacturers, retailers, policymakers, regulators, service businesses, and clients. Class 1 and Class 2 batteries must utilize UL 2580. Testers will test some battery parameters to examine how the battery reacts to conditions in such simulations. UL 2580 battery test prevents battery producers by substituting sub-standard elements that could pose abrupt failures and possible security risks. This article will discuss how these UL 2580 tests are performed with test chambers and test chamber types used for UL 2580 battery tests.

 

Battery Crush Test (Horizontal)

Battery crush tester simulation of various kinds of power lithium-ion batteries in the practice of usage, the battery endured compression, Manually, pose the multiple requirements which could happen when the battery is pumped by battery smash test machine. UL 2580 test includes a horizontal battery crush test to mimic the squeezing situation of different power batteries at usage. The battery crush test system is also an essential instrument for analyzing and assessing battery solutions’ protection. Extrusion pressure is used from the hydraulic head of the piston. The squeeze proceeds until the hydraulic pressure head reads 17.2 Mpa; the Applied drive is all about 13KN.

When the maximum pressure is reached, the strain could be relieved. The prismatic mobile additionally revolves about its horizontal axis. To be able to create its broad negative and narrow side may defy extrusion pressure. Every sample cell is exposed to stress only in 1 way and should use different samples for every evaluation. Semi cylinder or hemisphere type batteries should be parallel to the extrusion apparatus’s surface and exposed to extrusion pressure. Regular UL 2580 battery tests are contained in the security standards below. They include easy tests for dimensional precision to dynamic testing to confirm that the item may endure any dynamic and static mechanical stresses to which it could be subject.

 

Seawater Immersion Test Equipment

There are UL 2580 battery test standards in place designed to estimate the results of seawater immersion at the package level. These are primarily utilized to rate the flow regeneration of these packs. Our instruction for testing the criteria is to determine if there is any significance to the automotive seawater immersion test system.

The seawater immersion test device connects all of the wiring harness, connector, and other parts in line with the entire automobile connection style.  Since the monitoring interval could have been made for an overly long general evaluation period, each test was run in parallel. The submersion boats were steel tanks made for the purpose. The immersion period was conducted in an arrangement for every single hour interval. Seawater was ready in a different tank big enough to serve one immersion evaluation by mixing water from a pond to provide salt to its objective. The answer was agitated to market homogeneous conductivity. Seawater was subsequently pumped to the boat in under 10 minutes. Observing both hour immersion, the seawater was pumped from the analyzed car’s immersion vessel and moved in the following boat for the next vehicle’s immersion.

When we do the seawater immersion testing for UL 2580 battery test certification, some electric vehicles behave unexpectedly. Regular events contained unintended activation of lighting, windshield wipers, and horns. These phenomena might have been a result of the closing of buttons while submerged from the conductive seawater. The 12-volt batteries discharged via the seawater and through other heaps within an hour. This might be beneficial if the release time is quite fast to prevent unintended closing of the primary contractors and possible shock hazard or threat of a shallow voltage arc with potential fire.

 

Thermal Runaway Test Machine

Damaged or greatly over-heated Li-ion batteries in electric vehicles may transit to some thermal emission response with other gas and heat discharge. The heat might make a battery fire, and speedy gas release can damage the battery-pack casing. To characterize the gas and heat launch of giant automotive Li-ion cells, a more heavy-duty test seat was designed, along with a test set.

UL 2580 battery test standard includes an increased overall awareness of the danger of thermal runaway. We have some other objective to fulfill. Batteries have been used chiefly on non-manned assignments as mobile energy densities are rising. So, this increased stored energy presents the outcome of thermal runaway. The thermal runaway test chamber must follow some procedures to conduct this test. An outside heater is used to heat cells to thermal runaway. A nichrome wire was formed to a little heater component. Then the heater component was subsequently connected to the cell utilizing Kapton tape. The addition of a cable wrap around the Kapton coated heater to maintain the heater from coming from the mobile because the Kapton is heated beyond this glue’s melting point. A continuous voltage is placed on the valve until the mobile goes to thermal runaway. During springs, testing is normally powered by 30 W to 50 W.

After the test is completed, some cells could port a substantial quantity of smoke. The cathode meeting had been blown from their mobile. The inner jelly had been blown from the mobile can. We can conclude after observing the results that the cell may temperature was hot enough to spark the Kapton tape wrap and trigger additional fire round the anode, or may, of the mobile.

 

Conclusion

UL 2580 testing is performed to ascertain if or not a battery or cell is appropriate for the purpose that it is designed before it’s approved for use in this item. As a second phase, eligibility also has testing completed battery packs until the item is approved for release to the client. The UL 2580 battery tests are often carried out to confirm that the cells satisfy the company’s specifications. However, they might also be utilized to check the cells into arbitrary limits determined by the engineer to ascertain the length of time the cells live under adverse conditions or unusual loads. It determines failure modes or safety variables. The battery packs must also be analyzed with the charger advocated for the program to guarantee compatibility.
