To comprehensively assess battery performance and safety, several categories of testing are performed at both the module and pack levels. These tests focus on electrical, thermal, mechanical, and environmental factors. This research article explores the key elements of battery module and pack testing, providing insights into. How do you determine when the battery should be charged if it's not being used or has been in long-term storage? How do you determine what type of material will be required for an enclosure? How do you plan for controlling thermals in the battery enclosure? Can Epec certify battery packs for other. This study takes the power battery pack of a pure electric vehicle as the research object, focusing on safety—a core concern widely emphasized in the automotive industry. In practical application scenarios, evaluating the safety of the power battery pack through a single operating condition fails. Central to the performance, range, and reliability of EVs is the traction battery pack, which powers the vehicle and enables it to function efficiently. Earlier, a 20-foot container could deliver 2–3. 5 MWh capacity, but technology is advancing toward compact five-megawatt-hour energy boxes.
