After completing the connection between the battery cells and the Battery Management System (BMS), a V-port battery is preliminarily assembled. However, for its long-term safe usage, we need to undergo the following important battery performance testing steps.
Step 5: PACK Comprehensive Testing Equipment
This step is primarily used to test the performance of the PACK, which refers to the battery pack. The battery pack testing equipment utilizes various sensors and electronic components to monitor various parameters of the battery pack, including current, voltage, temperature, capacity, etc. It can continuously record this data in real-time and analyze it to assess the state of the battery pack. For example, if any individual battery cell exhibits abnormal behavior, the battery pack testing equipment can immediately issue an alert to avoid potential safety issues. Additionally, the battery pack testing equipment can perform charge and discharge tests to evaluate the performance and lifespan of the battery pack. This helps manufacturers and operators to identify issues early and take measures to ensure the reliability of the battery pack.
Step 6: Aging Test
Step 6: Voltage Delta Test
Voltage delta testing for batteries typically refers to the assessment of voltage differences among various positions within the battery during operation. These differences may arise due to internal chemical reactions, aging, wear, temperature variations, or uneven loads.
Step 7: Final Assembly
For the final assembly, we will utilize an ultrasonic plastic welding machine. This machine is a high-tech device used for welding thermoplastic products. It employs high-frequency vibration to melt the contact surfaces of two plastics and form strong molecular chains. The advantages include ease of operation, fast welding speed, high welding strength, and high production efficiency.
