Electric vehicles (EVs) have revolutionized the automobile industry, offering a more sustainable and energy-efficient mode of transportation. One of the essential components of electric vehicles is their rechargeable batteries. In this guest editorial, David Wallach explains how the performance and longevity of rechargeable batteries are critical to the success of electric vehicles, and why battery testing is a vital aspect of electric vehicle development and maintenance.

Electric vehicle battery testing is necessary to ensure the safety, reliability, and performance of electric vehicles in all operating ambient conditions. It involves testing the battery's capacity, energy efficiency, cycle life, and thermal stability. Philip Preston, President of PolyScience shares, “the battery is a critical component of an electric vehicle, and any issues can lead to reduced driving range, power output, and safety concerns. Therefore, testing batteries helps manufacturers ensure that they meet safety standards and provide optimal performance for consumers.”

Temperature control is a critical component of many industrial and scientific processes, and is a crucial factor in battery testing as it directly affects the performance and lifespan of electric vehicle batteries. Accurate temperature control can make or break the success of a process, impacting product quality, yield, and cost-effectiveness. Moreover, temperature fluctuations can affect battery capacity and charging speed. During charging, if the battery gets too hot, it can reduce the charging speed, leading to longer charging times. Similarly, if the battery is too cold, its capacity can become limited, reducing the driving range of the vehicle. Therefore, temperature regulation is necessary to ensure consistent and efficient charging of electric vehicle batteries.

“As electric vehicles become more prevalent, there is a growing need for rigorous testing of their batteries. This is because the battery is one of the most critical components of an electric vehicle and is responsible for providing the energy needed to power the vehicle. Battery testing is essential to ensure that electric vehicles are safe, reliable, and efficient,” says Preston.

One of the key components in battery testing is the industrial chiller. PolyScience is a leading manufacturer of temperature control solutions for an extensive range of applications, including chillers. An industrial chiller is a cooling unit that helps maintain a constant temperature in the battery testing chamber. The importance of industrial chillers in electric vehicle battery testing can be summed up in three words: accuracy, reliability, and safety.


In order to accurately test an electric vehicle battery, it is essential to maintain a consistent temperature within the testing chamber. This is because temperature fluctuations can affect the performance and lifespan of the battery. Industrial chillers help maintain a constant temperature, ensuring that the results of the testing are accurate and reliable.


The reliability of an electric vehicle battery is critical to its overall performance and safety. Industrial chillers play a critical role in ensuring the reliability of the battery by maintaining a constant temperature during testing. This helps identify any weaknesses or defects in the battery that could impact its long-term reliability.


The safety of the electric vehicle battery is paramount. Batteries that are not properly tested can pose a risk to both the driver and the environment. Industrial chillers are essential in ensuring that the battery is tested in a safe manner. By maintaining a constant temperature, the risk of overheating, venting, rupturing, or other safety hazards is greatly reduced.

Industrial chillers also play an important role in the manufacturing process of electric vehicle batteries. In order to produce high-quality batteries, the manufacturing process must be tightly controlled. Industrial chillers provide thermal management during the manufacturing process, which helps ensure that the end product is of the highest quality.

Another benefit of industrial chillers in battery testing is that they can help reduce testing time. By maintaining a constant temperature, the testing process can be completed more quickly and efficiently. This means that manufacturers can produce more batteries in a shorter period of time, helping to meet the growing demand for electric vehicles.

Preston shares that, “industrial chillers are essential in electric vehicle battery testing and the safe evolution of the entire industry as manufacturers try to make more powerful, longer lasting batteries. They play a critical role in ensuring the accuracy, reliability, and safety of the battery.” As electric vehicles become more prevalent, the use of industrial chillers in battery testing will continue to grow in importance. By investing in high-quality industrial chillers, manufacturers can produce safe, reliable, and efficient electric vehicles that will help shape the future of transportation.
