6 FAQs about [Battery mechanical load standard]

What are the safety standards based on mechanical loading?

Since providing a safe performance is of significant importance, different tests and safety standards have emerged as a highly advantageous method to comprehend their behavior under mechanical loading, such as SAEJ2464, UL1973, GB/T36276, and IEC62660-2 .

Do thermo-mechanical coupled loads affect battery performance?

Through the present work, it was found that limited literature exist that clearly define the influence of temperature and vibration. Therefore, comprehensive research still needs to evaluate the influence of the thermo-mechanical coupled loads on the battery performance.

Why are there no standards for mechanical tests on battery cells?

First, there are still no widely-accepted standards for mechanical tests on battery cells. Second, no general agreements have been made on which model (s) should be used to describe the mechanical behavior. These two gaps are inherently interconnected because tests should serve as the calibration of models and models can explain the tests.

Why is mechanical characterization of Li-ion batteries important?

In a narrow range of stress state, various models have nearly identical performance. Mechanical characterization of Li-ion battery cells is becoming increasingly important as the community becomes more aware that the underlying mechanisms of battery failure and degradation involve the complex interplay between electrochemistry and mechanics.

What are the parameters of a battery?

The state of the battery is mainly defined by two parameters: state of charge (SOC) and, state of health (SOH). Both parameters influence performance in the battery and are dependant on each other (Jossen et al., 1999).

How can mechanical tests be used to evaluate battery failure risk?

Therefore, mechanical tests can be used to evaluate the failure risk of the battery cells. A well-known example is the nail penetration test which is widely applied for the study of thermal runaways. The cell structure can be easily fractured by the sharp rigid tip, causing direct contacts among layers, and causing short circuits , .
