CLIMATIC TESTING OF BATTERIES: TECHNOLOGY AND SAFETY FOR A MORE RELIABLE ENERGY FUTURE

 Today, batteries are a key component in strategic sectors such as electric mobility, renewable energy storage, consumer electronics, and aerospace. Their development not only demands high storage capacity and efficiency but also reliable and safe behavior under extreme conditions. This is where climatic testing plays a crucial role.

At DYCOMETAL, we have extensive experience in designing and manufacturing advanced climatic chambers for battery testing, both in R&D and validation processes. These chambers simulate demanding environments that replicate the real-world conditions batteries may be exposed to throughout their service life.

What is evaluated in climatic battery testing?

Climatic tests expose batteries to controlled variations in temperature, humidity, and pressure with the aim of:

• Analyzing thermal behavior under extremely cold or hot conditions.
• Accelerating aging processes to detect premature failures or material degradation.
• Verifying stability under repeated thermal cycles or intermittent usage.
• Assessing the response to overcharges, pressure changes, and other external stress factors.

These tests are essential for ensuring the safety, durability, and efficiency of the final product, especially in critical applications where a failure could have serious consequences.

WHAT HUMIDITY RANGE IS BEST FOR MY CLIMATIC CHAMBER?

Climatic chambers can control either the temperature or the humidity within them. This is a point that is sometimes difficult to understand, because the relative humidity (RH) percentage will depend on the existing temperature. The higher the temperature, the more moisture the air can hold.

Relative humidity is the ratio of the amount of moisture in the air to the amount it can hold. Changing the temperature changes the relative humidity, which makes temperature control very important, since stable temperatures ensure a stable humidity level.

The normal humidity range for test chambers is usually between 10% and 98% RH, ranging from 10°C to 90°C and limited by the dew point. Test chambers use the dew point to establish the relative humidity limit.

The best way to understand this theory is to look at the temperature vs. relative humidity diagram, which indicates the manufacturer’s humidity limits. It is important to work within these limits to prevent damage to the cooling system.

To achieve lower humidity levels, the chamber is usually equipped with an air-drying system to allow the coil to drop below freezing.

Climate testing regulations have well-defined temperature and humidity ranges. Please indicate the regulations you wish to follow so that DYCOMETAL can offer you the most comprehensive equipment in the humidity ranges you need to perform your tests. Since humidity depends on temperature, indicate the temperature points and the humidity at those points you wish to define so that we can properly define the humidification systems.

WHAT NEGATIVE TEMPERATURE RANGE DO I SELECT FOR MY CLIMATIC CHAMBER?

Climatic chambers can control both positive and negative temperatures. For positive temperature control, the chambers use electric heating elements, but for negative temperatures, there are different cooling options. Most climatic chambers use a mechanical system based on refrigerant gas compressors to perform the cooling.

There are several negative temperature ranges, but the standard used and the type of material or sample being tested will determine the negative range. The following must be taken into account: the negative temperature range indicated in the standard, energy dissipation, mass, and type of material, in order to calculate the cold group and determine whether it is the most appropriate. For example, if you want to lower the test temperature to -40°C with a large mass and high dissipation, a single-compressor chamber will not be sufficient, and you will need to select a two-compressor system with a larger negative temperature range.

There are several alternatives for lower temperature ranges, based on mechanical cooling or an expandable refrigerant.

• Ambient +10°C. This lower limit is common for non-cooled chambers. Since the fan generates its own heat, temperatures close to ambient cannot be guaranteed. If a temperature close to ambient is desired, a cooling system will be necessary.

• -25°C. This is a considerably lower range that can be achieved by refrigerants commonly used in refrigerators or air conditioners, using a refrigerant gas.

• -40°C. This type of cooling system is commonly called single-stage, as there is only one compressor in the cooling system.

• -70°C. Systems called cascade or dual-stage. The high stage will be used to cool the low stage, allowing the temperature limits to be lowered. The high stage will ensure no overpressure or overheating.

• -86°C. To achieve this cooling, a triple cascade cooling system is used. This is rare in climatic chambers, however, it is common for ultra-low temperature freezers.

• -170°C. Chambers that reach these limits use liquid nitrogen for cooling. Nitrogen is an inexpensive method for cooling a chamber; however, prolonged use can be expensive. It is typically used for tests requiring gradients close to 30°C/min with a small volume.

Remember, provide as much information as possible to the DYCOMETAL technical department so they can configure the most appropriate equipment for your solution.

PROHESION, MODIFIED SALT SPRAY TEST, ASTM G85-ANNEX A5

ASTM G-85 is a corrosion standard that establishes a number of methods for modified salt spray testing. These variations described in the standard are useful when a different or more corrosive environment than the salt spray described in ASTM B117 tests is desired. This method is applicable to both ferrous and non-ferrous metals, as well as organic and inorganic coatings.

Within this standard, Annex A5 establishes test criteria based on stages of slightly acidified salt spray, followed by exposure to drying at a temperature above the test temperature by inlet of fresh, unsaturated air. These conditions have to be taken into account when designing the chamber, since this second stage requires a modification of a standard salt spray.

The SSC salt spray chamber models can have this test in their configuration by means of a design and programming modification, and this test can be carried out as an option of the standard configuration in any of the models offered.

WHAT POSITIVE TEMPERATURE RANGE SHOULD I SELECT FOR MY CLIMATIC CHAMBER?

 Once we have selected the most suitable chamber volume, it is time to select the positive and negative temperature ranges to perform the tests. In this case we will focus on the positive temperature ranges that an environmental test chamber can have, i.e. heating.

The climatic chambers have a heating system based on electrical resistors that generate heat, placing a greater number of resistors will increase the heat generated and therefore the upper range of temperatures and higher heating rates.

Normally the standards indicate the positive test temperature, but sometimes it is the sample itself that will mark the maximum temperature range it can withstand. Always select a maximum temperature range in which you will be working.

Depending on the application for which the chamber is to be used:

• +50 ⁰C. A range for environmental stability testing where the product is subjected to the normal ambient temperatures it will encounter throughout its lifetime. It is used for pharmaceutical industry, biotechnology or in some construction materials testing. Its insulation is usually expanded polyurethane.

• +85ºC. They are modular type chambers or intended for industries where it is not necessary large upper temperature limits such as. These chambers will use polyurethane as insulation.

• +150 or 180 ⁰C. Most of the chambers have this temperature range. It is a dedicated range for industrial sector like automotive, electronics, aeronautics, etc. The insulation shall be composed of mineral wool. These ranges should not be exceeded due to the risk of overheating of the cooling oil.

• +200 °C. Range for thermal shock chambers. As both test chambers (hot and cold) are separated, the cooling limit of the cooling oil may be exceeded.

• ≥ +200 °C. This range is used for stoves, ovens or muffles that do not have a cooling system. This allows the upper temperature limit to be raised.
