With the popularity of electric vehicles, the performance and reliability of batteries have become the focus of attention. The performance of batteries changes at different temperatures, making high and low temperature testing of electric vehicle batteries particularly important. These tests ensure the driving safety and long-lasting performance of batteries under extreme temperature conditions.

SONACME Technology provides Battery Test Chambers for electric vehicle battery system testing to help manufacturers design reliable power cells. Before batteries can be released, manufacturers need to prove that their products can power electric vehicles in low and high temperatures in different environments and seasons. Electric vehicle batteries must be resilient enough to withstand the extreme internal and external temperatures that affect battery efficiency.

Temperature and Electric Vehicle Battery Risks

Performance

The performance of electric vehicle batteries is often temperature dependent, with moderate temperatures improving the performance and storage capacity of lithium-ion batteries. Exposure to extreme temperatures can lead to damaged, dangerous and degraded batteries:

• Reduced driving range

• Reduced charging capacity

• Reduced power

• Shorter lifespan

Safety                                                                                                                                    

Vehicle manufacturers must ensure the safety of the user during standard operation as well as in the event of an accident or malfunction in order to comply with national and international regulations. Electric vehicle batteries often include protection to reduce the risk of thermal runaway, an uncontrolled and rapid rise in pressure and temperature that can lead to fire or explosion.

We manufacture a wide range of environmental climate test chambers that can accurately control the rise and fall of internal temperatures. We have a wide range of high and low temperature battery explosion test chambers in different sizes to suit a variety of battery designs and dimensions.

High Temperature Testing

High temperature testing predicts how a battery will react in real-world environments, including:

• Direct sunlight

• Heat

• Humidity

The materials used in electric vehicle batteries determine their response to temperature extremes. Ourbattery test chambers can gradually increase the temperature to 180°C and measure and monitor it throughout the test:

• Battery voltage

• Battery Capacity

• battery performance

Low Temperature Testing

SONACME Technology's Battery Test Chambers can test electric vehicle batteries at low temperatures. Although electric vehicle batteries tend to perform best in the moderate temperature range, lithium-ion batteries have reduced capacity and longer charging times in cold weather.

Low temperature testing involves gradually lowering the temperature inside the chamber and recording the battery's response. Our environmental test chambers can reach temperatures as low as -70°C to simulate extreme conditions. Cryogenic testing provides manufacturers with important performance data, including:

• Battery voltage and capacity

• Battery efficiency when starting a vehicle

• Factors contributing to battery performance degradation

High and low temperature testing of electric vehicle batteries is an important part of ensuring safe and long-lasting performance on the road. These tests evaluate the performance, reliability and safety of batteries under different temperature conditions and help manufacturers improve product design and provide a better user experience. Through scientific and rigorous high and low temperature tests, we can drive electric vehicles with confidence and enjoy a more efficient and environmentally friendly way of travelling. 

SONACME Technology manufactures Battery Test Chambers in accordance with the standards and guidelines set by ISO, IEC, MIL-STD, RTCA DO and other industry organisations. Please contact us to develop your solution for EV battery testing.
