The 220V battery pack, composed of 19 individual 12V batteries connected in series (12V/only*19), is subjected to a continuous discharge for 1 hour using a pre-discharge current of 2I10. During this period, a surge current of 22I10 is applied for 0.5 seconds without interrupting the pre-discharge current. The test is designed to evaluate the battery pack's ability to maintain stable voltage under high-current conditions. Throughout the entire process, the terminal voltage of the battery pack must not drop below 202V during the surge discharge. This requirement ensures that the battery can handle sudden load changes without failing, which is critical for applications where power stability is essential. The test also helps verify the reliability and safety of the battery system under extreme conditions. By simulating real-world scenarios, such as sudden power surges or short circuits, engineers can assess the performance and durability of the battery pack. This kind of testing is commonly used in automotive, industrial, and energy storage systems to ensure compliance with safety and performance standards. Proper execution of this test is vital for ensuring long-term operational integrity and preventing potential failures that could lead to system downtime or safety hazards.
