Hi, everybody! Welcome to a topic that in today's high-tech world is continuing to become more important, “battery safety and performance” at high altitudes. You're probably asking yourself, "Why do I care about batteries at high altitudes?" Well, if you do things like aviation, space exploration, or even high-altitude transportation, this is a big deal. But it's not only in those niche areas.

Battery Altitude Chamber : The Solution

We have the Battery Altitude Chamber, which is a special testing chamber that duplicates both the low pressure of high altitude and how batteries tend to perform in those extreme harsh environments.

What is a Battery Altitude Chamber?

The Battery Altitude Chamber is a controlled chamber that subjects a battery to a simulated high altitude. It incorporates such parameters as reduced air pressure, temperature, and humidity attuned to a battery's response. This allows the manufacturers to test how their batteries will behave if submitted to the pressures, or lack of pressures, fed to them within high-altitude environments.

Benefits of Using an Altitude Chamber

So, why should you care about Altitude Chambers? Let's explore the key benefits:

1. Ensuring Safety and Reliability

What is at stake at these high altitudes could be anything, from aviation and aerospace research to simply flying at great heights with drones; safety is a big concern. The Altitude Chambers will test how your product performs under the extreme conditions that it is being faced with in the real world. This will show potential failure points so that your product can be made not only functional but also safe and reliable.

2. Improvement of Product Performance

Ever wondered at some point why mobile phones, laptops, or even drones function seamlessly at high altitudes? It is due to the fact that they have been thoroughly tested in Altitude Chambers! Manufacturers use these chambers to tweak the performance of their products by clearly identifying the impact of altitude on battery life, component stability, and general functionality. The outcome is products that function consistently, regardless of where they are used.

3. Compliance with International Standards

If you design products for aerospace, military, or the consumer electronics industry, there is no playing around with compliance to international standards.  Altitude Chambers give you the ability to comply with these standards by creating the required testing environment for certifications such as UN 38.3 (for lithium batteries) and IEC 60068-2-13 (for environmental testing).

4. Reduction of Risks and Liability

Imagine the cost and reputation damage if a battery fails mid-flight or if there is a malfunction of some critical part in space. Altitude testing significantly reduces these risks because manufacturers can catch and fix their potential problems during the development phase. 

5. Versatile Testing Capabilities

Altitude Chambers are so versatile. This equipment can simulate a wide range of conditions, starting from high temperature extremes, changing humidity, and even rapid decompression events, among other things. 

Uses of an Altitude Chamber

Altitude Chambers are used throughout various industries, and their applications are as diverse as the conditions they simulate. Examples are present in numerous and multifaceted areas, but some of the general areas of application of these chambers are:

1. Aviation and Aerospace

The environment seems completely different, when you’re at 35000 feet, from what we find on the ground. The tests are to make sure all the vital systems function in the thin, cold air at high altitudes, thereby maintaining the safety and efficiency of flight operations correctly.

2. Space Exploration

Space is a high-altitude environment, almost perfect in vacuum, with the temperature varying from one extreme to another. The main application of these chambers can be seen in the testing of satellites, spacecraft, and above components with a view to attesting the ability to withstand the harsh realities of being in space. Such testing is indispensable for space missions to be successful, so that failure of equipment may have catastrophic consequences.

4. Consumer Electronics

You might not even think about it, but most consumer electronics also travel at very high altitudes. The manufacturers need to know that those things work, be it that you hike high up the mountains or fly high with your drone. It, therefore, goes without saying that altitude chambers offer manufacturers a means to establish that everything can work under such conditions.

5. Automotive Industry

High-altitude tests are equally adopted in the automobile industry, especially in cars that are intended for operation in or at elevated heights or extremely mountainous terrains. Altitude Chambers are ideal for testing engines, the braking system, and other important components in the drivetrain that ensure they work efficiently at various altitudes.

Standards of Altitude Chambers

Given their critical role in safety and performance testing, Altitude Chambers must meet standards to ensure accuracy and reliability. Let's take a closer look at some of the key standards that govern altitude testing:

1. UN 38.3

This standard is most relevant to the shipment of lithium batteries by air. UN 38.3 subjects batteries to altitude testing to simulate 15,000 feet conditions. The idea behind this standard is, batteries should not leak, vent, or explode under low pressure.

2. IEC 60068-2-13

This standard was set by the International Electrotechnical Commission. It includes checking how much pressure material can endure at high altitudes. 

3. MIL-STD-810G

This military standard details testing methods and procedures to determine the effects of environmental stresses on military equipment. Guidelines for altitude tests are included to ensure the working of the equipment in conditions of high altitude.

4. RTCA DO-160

This is a standard followed in the aviation industry to test the environmental conditions that the avionics equipment has to go through. Altitude test is taken so as to assure that the electronic components work at altitudes normally reached during a flight.

5. ASTM D6653

This standard provides guidelines for altitude simulation testing, especially for packaging used in air transport.

FEED CURIOSITY!

How high does this machine simulate altitude conditions in the chamber?

This machine can simulate up to 45000 meters of altitude conditions.

How long does an altitude test normally last?

The simulation length varies from the limit of a few hours, or even minutes, to several days, considering the test parameters.

Can the chamber simulate more than one altitude in one test?

Yes, it can simulate a diversity of altitudes in one test session to estimate battery performance over a variety of elevations.
